New takes on kites!

8 03 2010

Here are the kites I was talking about earlier. These kites are a little different from the traditional kites, but will fly just as well and are a little more interesting.

If you have a lot of time and want a challenge, try making this tetrahedral kite:

Supplies:

60 long, straight drinking straws
Scissors
Kite string or thin, strong string that will stay knotted, at least 30 feet
4 wooden dowels, 1/8 diameter
Big sheet of paper
Newspaper, cellophane, or plastic bags
Tape
A pen/marker

1. Cut your string eight times as long as one of your straws.

2. String three straws together by pushing the string through the straw with a dowel. Tie the straws into a triangle. Leave two inches of string at the end. Then use the longer piece of string and pull it through two more straws and tie a knot so it looks like this:

3. Use this frame to make a pattern. Place the frame on top of the sheet of paper and trace around it, leaving about a one inch around the edge. Cut it out and use it to make ten cutouts of the newspaper, cellophane, or plastic bags, whatever you would like your kite’s shell to be.

4. Use the leftover string in the frame and add another straw onto the triangles. This makes a 3-d triangle, which will be one cell of the kite. Take the frame and place it on one of your cutouts. Attach with tape.

The kite frame.

Covering the frame with the shell.

5. Make 9 more cells. Attach all the cells together in the shape of a triangle with the leftover bits of string. To make them more secure, you can tape the knots and excess string to the inside of the cells.  Make sure all sides covered with the cutouts are facing the same direction.

The first layer should have 6 cells, the second should have 3, and the top layer should only have 1 cell.

6.  Cut off excess string between the cells. Along the leading edge of the cells tape your dowels to the straws for reinforcement.  Then cut two small holes on the top cell’s and lower cell’s shell, each in the middle of the cells. Tie the string around the dowels and straws and secure with tape. Then take the string you want to fly the kite by, and tie it one-third of the way down from the top of the kite. Wrap the excess around the left over dowel. It’s now ready to fly!

A kite ready for flight!

To make a kite out of recycled materials and for almost no money, try this:

Supplies:

Plastic shopping bag
Two thin wooden sticks
Duct tape
String

1. Take the two sticks and lay one other the other perpendicularly, so it looks like a + sign. Then take one piece of the duct tape and place it over where the sticks intersect.

2. Attach the 4 ends of the sticks to the bag with the tape. Then attach the string to another piece of tape and stick that piece to the bag of the center tape piece. Now it’s ready to fly.

I love my new kites and can’t wait to fly them at the festival or during the next few months.  I hope you go out and fly some too!





Everyday Science at C-Day Camp!

16 02 2010

On Monday at the Museum we had a C-Day Camp. We did a bunch of activities like writing secret messages, growing Lima bean plants and creating Shrinky Dink charms.

As part of the day, we made polymer slime. A polymer is made up of long chains of molecules, and in this experiment the polymer is glue.  When Borax is added to the glue it turns it into slime. To find out how to make this slime yourself, click here!

After we made our slime, we discovered how the inside of a diaper works. Seems icky, but it’s scientific! The special polymer inside of a diaper can absorb eight times its weight, allowing nothing to leak. Cool, huh? Check out a C-Day video of it here.

Because we know how well this polymer works, we poured two cups of water into the diaper and trusted it enough to put it over our heads. Then we cut open the diaper and actually felt the polymer.

Before the day ended, we made Shrinky Dinks. Shrinky Dinks are also made of a polymer.  When you put them in heat they shrink and harden as their long strands of molecules are forced closer together.

First we colored the Shrinky Dinks with permanent markers.

Then we heated them up in the oven until they shrank and became hard.

After the Shrinky Dinks cooled, we could put them on to string and make necklaces or bracelets with the charms.

These activities can all be done at home, so be sure and try one!

 





Happy Valentine’s Day!

10 02 2010

Instead of making a regular Valentine’s Day card, impress your valentine with these secret message cards.

Supplies:

1-2 sheets colored construction paper, we used pink and purple
1 sheet of white paper
Red cellophane or plastic wrap
3-5 red, orange, and pink markers
1 light blue pen
Scissors
Glue stick

Instructions:

1. Cut a large heart out of the colored construction paper. Cut a smaller heart out of the white paper to fit in the colored heart.

2. Cut a smaller heart out of a piece of colored construction paper and then cut out the middle, leaving a frame in the shape of a heart. Save the middle for decoration.

Cutting the hearts out.

3. Write your secret message or messages in the white heart using the blue pen.

The secret messages.

4. Write over the secret message with your red, orange, and pink markers. Paste the white heart on top of the larger heart. Use the middle of the heart frame to decorate the card.

My decorated valentine, almost ready for decoding!

5. Cut the red cellophane or plastic wrap to fit the smaller outline of the colored heart. The easiest way to do this is cut a square out of your cellophane or plastic wrap that is a little bigger than your heart. Glue the cellophane or plastic wrap down and cut off the extra around the border of the heart.

6. Now have your valentine decode the message!

What can wind do?

27 01 2010

Did you know that wind is very important?  Wind can shape landforms like mountains through erosion.  It can make new plants by blowing their seeds to new places or helping to pollinate existing plants. Birds decide their course because wind can help push them in a certain direction. Sometimes wind can help airplanes and kites in the same way. Wind can also cause bad weather like hurricanes or tornados.

New wind turbine.

Nowadays, we use wind turbines to create energy.  These turbines look like giant, skinny windmills, and are all over the world. When the wind blows, air moves the blades and they begin to turn. When this happens, it starts a generator in the turbine which creates energy. This new energy can power anything electricity can, but it is better for the environment because it does not cause pollution by putting bad things in the air.

To see how wind works for yourself, you can make this pinwheel at home.  Like the wind turbines that create energy for us, this pinwheel also works by catching the wind under its blades to spin.

Supplies:

Construction paper
Ruler
Scissors
Pencil
Push pin
Unsharpened pencil with eraser
Dime
Markers or crayons
Glue stick
Hole punch

Instructions:

1. Measure and cut a 4 1/2″ square out of your paper. Decorate the paper with markers or crayons.

2. Place the dime in the middle of the square and trace around it.

3. Cut from each corner towards the center, stopping at the dime’s outline. You should have 4 sections.

4. With your hole punch, punch the top right corner of each section and the center of the dime’s outline.

5. Use the glue stick and put glue around the center hole. Then bring one of the corners to the center and line up the holes. Press down and make them stick together. Continue to put glue on each corner that you place down, this way they can all stick together. Also make sure the holes are always lined up.

6. Carefully take your push pin and put its needle through the holes. Push the needle end through the pencil eraser. Now you have a pinwheel! Go outside and test it out if it’s windy. If not, try blowing on it or putting it in a room that has a fan or air vent.  

Other than moving our pinwheels,  shaping the land, making plants, helping animals and providing new energy for us, wind can also be fun! Starting Saturday, the Museum’s new exhibit Air Fair will show us the power of wind and more exciting things it can do. To learn more about wind energy, visit Energy Kids.





Rainy Day Fun

15 01 2010
Just because it’s raining outside doesn’t mean you can’t have fun.  A rainy day is perfect for making crafts, reading or playing games.

Today at the Museum everyone made the most of the rain by playing in Tinker’s Workshop, exploring, or going to Storytime.

Everyone listened and watched as Paul read "The Mixed-Up Chameleon" by Eric Carle.

Later, someone else made a card with paper cutouts in the workshop.

What do you do on rainy day?





Mathematical Holiday Decorations

11 12 2009

These decorations are so easy to make! They make great holiday flare for Hanukkah or Christmas. All you need is colored paper, a ruler, scissors, and a stapler.

First, cut some colored paper into 1 inch strips. You will need 7 strips of paper. Then use a ruler to measure and cut the strips. You should end up with:

- two 12 inch strips

- two 10 inch strips

- two 8 inch strips

- one 6 inch strip

Stack the strips of paper in this order: 12-inch, 10-inch, 8-inch, 6-inch, 8-inch, 10-inch, 12-inch. It’s a measurement sandwich!

Now, staple one end of the stack. Next, gather the other ends of the strips together and staple them. You can tie a string around the top if you want to hang it up.





Salt dough tree ornaments

3 12 2009

Sure, you can shop for tree ornaments, but why not bring out your creative side by making ornaments at home? Homemade ornaments add a special touch to any Christmas tree because they were made by you!

These salt-dough ornaments look sweet hanging on any Christmas tree, but be warned, they’re not sweet to eat! Although inedible, making salt-dough ornaments is similar to baking cookies.

What you need:

-2 cups of all-purpose flour

-1 cup of salt

-1 cup of water

-Rolling pin

What to do:

1. Preheat the oven to 250 degrees.

2. Whisk the flour and salt together in a bowl.

3. Add water and stir thoroughly until there are no more traces of flour.

4. Knead the dough on a flat surface until it’s smooth. This will take about 8 to 10 minutes. Try not to let the dough get too rubbery by kneading it too long.

5. On a floured surface, roll out the dough until it’s about a quarter of an inch thick. (Mine were a little on the fat side, however)

6. Use cookie cutters to cut out shapes or carve out your own. Place the shapes on an ungreased cookie sheet. Make a hole at the top of each ornament big enough for a yard or ribbon to fit through.

7. Bake for 2 hours.

This craft came from Anna Getty’s eco-friendly book I’m Dreaming of a Green Christmas. See what other ornaments you can make from things found around your house!





Fall felt apples

19 11 2009

These quaint felt apples make sweet trinkets this fall! They fit so nicely in the palm of your hand and make nice giveaways for Thanksgiving as well.

I originally got the idea from the Web site Kaboose, but made a couple adjustments based on the materials I had.

What you’ll need:

-Red and green felt

-A coffee stirrer or popsicle stick

-Hot glue gun

-Polyester fiberfil (like stuffed animal stuffing!)

-Brown marker or paint

-Scissors

What to do:

First, color the end of the coffee stirrer brown with either a brown marker or paint. Break off the end so it’s a couple or so inches in length. Set it aside for later.

Cut a plus-sign shape out of the red felt. If you prefer a shape to trace, you can download a printable shape provided by Kaboose here. I used a red marker to trace the plus-sign so it showed up just enough for me to see where I was cutting.

Tear off a piece of fiberfil and squeeze it into a ball shape. Glue it in the center of the plus-sign with either regular Elmer’s-type glue or the hot glue. Try to keep the puff ball as compact and round-shaped as possible.

Fold up two of the sides so they meet at the top. Then begin hot gluing the other sides one at a time so they stick to the sides you folded up. Hot glue is good because it dries quickly. When you’re done, you can peel off the excess strings of glue.

Now take your coffee stirrer and stick it in the middle. Glue a line along the opening and seal the top shut. Cut out a leaf shape from the green felt and glue it on top.

Voila, felt apples for the fall season! Happy crafting!





Colorful turkey hands

17 11 2009

Making turkey hands is an easy and classic Thanksgiving art craft!

First, trace your hand on a sheet of paper and use the outline of your hand as the body of the turkey. Then there are lots of different ways you can decorate your turkey.

I painted one of my turkeys with watercolor paint—it dries quickly! For my second turkey, I used markers to write things I’m thankful for in the “feathers.”

Other creative ways to decorate and use your turkey hands:

-Glue on corn kernels, rice grains or other seeds to give your turkey texture

-Cut your turkey out and tape it on your window to make a window cling

-Or, cut out multiple turkeys and write the names of all your family members to make Thanksgiving dinner table place cards

-Tear or cut pieces of magazines and glue them inside your turkey to make a turkey-shaped collage

What are some other things you can do with your turkey hands?





Origami Thankfulness Box

6 11 2009

Thanksgiving and the winter holidays are coming up, so everyone is in the giving mood! Maybe you would like to show someone why you’re thankful to know him or her. Or maybe you want to keep track of the things you are thankful for in a Thankfulness Box.

origami masu boxes

Either way, origami—the Japanese art of paper folding—is a great way to get crafty!

This box is called the masu box. A long time ago, people in Japan used to store their rice in wooden masu boxes. You don’t have to store rice in these paper boxes, but you can keep other keepsakes in it. I think these are great for holding candy, erasers, or buttons!

Here’s an idea: since Thanksgiving is coming up, why not start writing down on little slips of paper the things you are thankful for in life? Try coming up with one each day until Thanksgiving—it sounds like a lot, but there are a lot of things to be thankful for in this world!

After you write it down, fold it up and store it in your masu box. You can get your family to try this too! Then on Thanksgiving, sit down with your  family and all of you can share what’s inside your Thankfulness Boxes.

thankfulness box

Another thing you can do is think of someone who means a lot to you in life, such as a grandparent, teacher, or best friend. Write a  note about why you are thankful to have this person in your life. Put it inside the origami box along with a momento, such as a photograph or friendship bracelet. Surprise that person with your giftbox!

I think the web site Paper Crane gives clear instructions and good illustrations on how to fold the masu box . Click here to see them.

The Netflix Origami website also shows you a cool way to recycle “junk paper” and make a masu box with a lid! It has a lot of helpful pictures that make it easy to follow as well. Check it out here!

To whom do you plan on giving your super neat giftbox? What are you thankful for this year?





Yarn pumpkins

20 10 2009

The Make and Takes blog shows you how to make this great Fall craft, little yarn apples. I decided to use orange yarn and make yarn pumpkins instead.

yarn pumpkins

They were so easy to make and took hardly any time. I can’t wait to decorate my desk with them and given them away as little presents.

You can also give them away with candy on Halloween to trick-or-treaters.

Check out Make and Takes for the instructions on how to make yarn apples (or pumpkins!).





Make a terrifying T-shirt

13 10 2009

Audrey, the Museum Programs Coordinator, just showed me a cool way to transform a regular T-shirt into a TERRIFYING T-shirt with just Sharpies and rubbing alcohol.

Terrifying T-shirt!

What you need:

-A T-shirt to decorate (colors show up best on light-colored shirts)

-Sharpies of various color

-Rubbing alcohol

-Pipette, eye dropper, or spoon to distribute the rubbing alcohol

-Cardboard that can fit inside your T-shirt

bloody knife wound

Put the cardboard inside the shirt so the colors don’t bleed through the fabric. Then begin drawing designs on your shirt. Use the pipette or other tool to drop small amounts of rubbing alcohol on the desgins. The rubbing alcohol makes the ink spread out in a circle. Sometimes the inks in one color separate, like the yellow coming out of the green ink in the picture below.

tentacle and scar

Once you’re done dripping the alcohol, let the shirt dry for 10-15 minutes before popping it in the dryer so the design sets. You can then add more embellishments on your designs afterward. Audrew made a creepy eyeball, a monster tentacle, and bloody scar out of her designs! 

creepy eyeball

Why does the ink do that?

Permanent marker ink is soluble in rubbing alcohol. Soluble is how you describe a substance if it dissolves in a liquid. For instance, salt dissolves in water so salt is soluble in water. Permanent marker ink, however, is not soluble in water. That’s why if you put water on your T-shirt drawings, the ink wouldn’t spread out like it does with rubbing alcohol.

Experiment with different colors and observe what happens with some colors, but not others. For instance, the color green is made up of yellow and blue. The rubbing alcohol brought out the yellow from the green. Does this work with other colors too?





Batty for bats and art

8 10 2009

Do you know how people began associating bats with Halloween?

bat

There are a lot of different stories that explain possible reasons why. One story says that in ancient times, people thought bats had magic powers and their presence indicated there was a ghost around! Another story says that a long time ago when people gathered around bon fires for warmth and warding off spooky spirits, the light from the fire would attract bugs and the bugs would attract bats!

Also, when bats hang upside down to sleep and wrap their wings around them, some people think their wings look like witches’ cloaks. Others think vampires transform into bats. Bats don’t always have a negative image, though—they sure do eat plenty of mosquitos!

handprint bat

To celebrate the upcoming Halloween, you can make your own handprint bat just like the one pictured above. It’s a cool and simple piece of art you can make at home with just paint, paper, and your hands.

First, put some black paint on a paper plate. You don’t have to use black though—you can use purple if you want purple bats!

Then rub your left hand in the paint so your hand is evenly covered. “Stamp” your hand on the paper. Your handprint is one of the bat’s wings.

Now cover your right hand in paint and put your handprint beside the one already on the paper. Let the paint dry and then add details to your bat, such as googly eyes, fangs, or even a bowtie!

Austin is actually home to the largest urban bat colony in North America. Over a MILLION Mexican free-tail bats spend their vacation under Congress Avenue Bridge! There are still some bats lingering around—check out this website to learn more about Austin’s bat colony and how to see them.





Make your own chopstick holders

28 09 2009

Sawadee ka! (I’m saying “hello” in Thai!)

Today I’m going to show you how to make your own chopstick holders, great for decorating the dinner table or giving away as presents. I got the idea from this cool web site!

chopstick holders

I didn’t have my chopsticks on me when I first made them, so I used pencils to show where the chopsticks would normally go.

step 1

First, take a regular-sized sheet of paper—already drawn on or left blank to decorate later—and fold it horizontally (also known as “hamburger style”). Cut down the crease so you now have two rectangles.

step 2

Take one of the rectangles and fold it in thirds so that one flap can easily fold on top of the other. Open it back up and fold the top two corners.

step 3

Next, fold the flaps back down again with the corners folded down so it looks like the photo below. If the flaps don’t stay down, you can use stickers or tape to keep the top flap down.

step 4

Now flip it over and fold the bottom up, securing it with tape. You can also use a sticker, like the green one in the picture.

step 5

Now you have your very own chopstick holders!

finished chopstick holders

Don’t know how to use chopsticks? Here’s a short, instructional video I made with the help of my friend Emily at the Museum:

If you’re still having trouble, here’s a trick for all beginners:

Cut a small segment of a straw and bend it in half. Stick the two ends of the chopsticks in the openings and then tape around the straw enough so the straw stays bent, but you can still move the chopsticks up and down. If you’re having trouble moving the chopsticks up and down, try taping the straw at a bigger angle for more springiness.

practice chopsticks

Now you have your own practice chopsticks! What sorts of things can you pick up with your chopsticks? How will you decorate your chopstick holders?





Turn an old book into an art journal

24 09 2009

recycled book

Old books lying around are great to re-use for collages and art journals. Find your creative side and imagine what kind pictures and designs you want to make inside!

The only things you need are an old book, scrap materials that can be found around the house, and art supplies such as scissors and a glue stick.

scrap magazines and newspapers

Instead of throwing away magazines or newspapers, save them to cut out shapes. Add color with markers or paint. Throw in some glitter or stickers!

Here are some ideas for journal entries:

Make a collage of your daydreams or what you dreamed last night.

Use pictures to record what you did today.

Illustrate your favorite poem.

Make up your own story and turn your art journal into a storybook.

What will YOU put in your art journal?
