Science Wonders
Links to help others earn this Try-It.
To earn this Try-It, we tried lots of different science experiments.
We learned about crystals; that salt, sugar, ice, and snow are all crystals, as well as most gemstones. We looked at different crystals with a magnifying glass to see their shapes, and learned that we could tell the difference between salt and sugar by looking at the shape of their crystals.
We looked at different rock crystals, such as quartz, calcite, and flourite, to see their different shapes.
Then, we made crystal pictures with epsom salts. You can do this, too!

Some other cool crystal experiments:
We played a game with magnets to find out what could be picked up with a magnet and what couldn't. We learned that the earth was a great big magnet and a compass would always point North because of this.
We used straws to blow bubbles on a wet plastic tablecloth and discovered that they would try to stick together. That made it easy to make long caterpillars out of bubbles! But it was kind of hard to make a bubble inside another bubble. The trick was to get your straw really wet on the outside with bubble solution before you stuck it into your big bubbles.
We tried to make bubbles of different shapes using our fingers or three straws tied in a triangle, but the bubbles always came out round! At the Children's Museum, we made a "flat bubble" inside a hula hoop, and then we had a contest to see who could stick their hand through it the farthest before it popped. (Whoever had the most soap up their arm was the winner.)

We watched chemical changes when we mixed baking soda and vinegar to make a volcano. Then, we learned how to blow up a balloon using the carbon dioxide gas produced when you mix baking soda and vinegar. Here's another cool way to blow up a balloon.
