Ocean Art: Using Wax and Water

26 11 2010

Have you ever noticed water droplets pooling up on the top of leaves and dripping off? The waxy layer on the outside of leaves is called the cuticle and makes the leaves waterproof. This keeps moisture inside the plant, allowing the rain water to soak into the soil and into the pant’s roots.

You can see wax repel water through this art project.  I drew fish using crayons, markers and colored pencils.  Crayons are made from wax.

Then I painted over the picture with blue watercolor paint, so it looks like it is under the ocean.  You can see how the yellow fish repelled the paint. The purple marker smeared a little, because it was also water based and mixed with the paint.

Mother’s Day

6 05 2010

This weekend is Mother’s Day.  For my mom, I’ve decided to make a couple of things I know she would like.  Instead of buying these things, I’m actually going to make them.

Today I’ll show you how to make custom-dyed carnations.  I thought it would be cool to give my mom something that shows a scientific process and that was pretty. Later this week I will show you the card I made.

Dyed Carnations

Supplies:

12 carnations
3 vases
A bouquet of white carnations, ends cut off at an angle after purchasing
Food coloring

1. Divide your flowers up into thirds.

2. In each vase place a couple cups or so of water. Make each vase of water a different color with the food coloring. I’m making pink, purple, and red. Leave the flowers in the vases for about a day or until you like the colors.

The color moves to the petals as the flower drinks the water. When a flower is growing from the ground, its roots spread out to find the water. When they find the water, the flower can drink it and grow even more.  When we bring flowers home from the store they no longer have roots.  However, these flowers still need water, which is why we put them in a vase. If you watch your flowers throughout the day they are drinking the dyed water, you can observe how quickly or slowly they drink water.

3. Fix into a bouquet or put them all in a new vase with un-dyed water. Now they’re ready to be a gift.





Spring is almost here!

3 03 2010

Even though the weather has been cold a lot, spring is almost here. As you probably know, in spring all of the plants and flowers bloom because the temperature changes.  When you’re out and about, try and spot the blooms and buds on the plants around you.

I went down to Town Lake to see if I could find some buds.  Here’s what I saw:

First I found buds on some bushy plants.

Then I saw some on the trees.

Then I saw some flowers.  Some were about to bud and some had even bloomed.

Tell us what you find when you go outside and look!
