Extreme Planet: Compasses, Scavenger Hunts, and Shelter-Building!

17 07 2012

Last week at the Museum, our full day camp for 7- to 10-year-olds explored the ideas of “Extreme Planet!”

For the first day of camp, we talked about the different things that would classify as “Extreme Planet.”  Not only did we talk about the Earth, but we also talked about the Earth’s extremes: hurricanes, tornadoes, and extreme situations!

After talking about all of the extreme possibilities on Earth, we went on a scavenger hunt to find all of the essential, basic elements that we could use to build a shelter to protect us from inclement (or really bad) weather.

During our scavenger hunt, we followed clues that told us which directions to go in to find our next shelter-building material.  For this part of the hunt, we used a compass! Does everyone know how compasses work?

One of our campers holds the compass during our scavenger hunt!

A compass is essentially a magnet, which reacts to the magnetic field of Earth.  This means that across all of Earth there are magnetic waves that the magnet of a compass reacts to.  The magnet, also called the needle, of the compass has one end marked to show which direction is North.  The reason that the needle always points North is because the North Pole has the opposite charge of the needle in the compass.  You’ve heard it before, but we’ll say it again: Opposites attract!!

Thus, the North Pole has a magnetic force that is opposite to the charge of the magnet in a compass, which draws the North tip of the needle towards the direction of the North Pole.

After finding all of our materials with the help of the compass, we came back to the Museum and built our best forts!

If you want to try to build a shelter to protect against harsh wind, rain, heat, or other extreme situations, just have a scavenger hunt of your own and collect all of these things:

- 1 card stock or thick piece of paper
- 1 plastic bag
- some tape
- 1 pair of scissors
- some string
- 5-10 skewers/sticks
- anything else you think would make a good shelter

Using any or all of these materials, try to build your own miniature shelter that can protect against extreme weather!  Share your photos if you’d like!

Here is what some of our campers came up with during camp!

Team Green went for a basic tent structure with their sticks and then later covered their shelter with the plastic bag to protect from the elements!

Team Blue built a shelter by curling their paper into a cone and covering it with the plastic bag to protect against rain and wind!

Team Red built a cube shape with their sticks and piece of paper before covering it all with their plastic bag to provide shelter from all of Earth’s extremes!
