Super Scientist Christina taught us about density by filling 2 clear jars with water. She then put an orange with a peel in one jar, and it floated to the top. She put a peeled orange in the other jar of water, and it sank. She taught us that the peeling causes little pockets of air to surround the orange causing it to float like a floatie in a pool. The orange with no peeling did not have the air pockets to keep it afloat. This was really neat, Christina. Great job!

Ethan taught us about chemical reactions and volcanoes! He used an already made volcano mountain and set it on top of an empty water bottle. He then poured baking soda in the bottle. The exciting part was when he added some vinegar which he had dyed with red food coloring. As soon as that was added, there was a big, bubbly reaction that erupted out of the bottle and poured over the volcano mountain. This was SO cool! We asked Ethan to do this several times for us. We learned that an acid (vinegar) mixed with a base (baking soda) causes a chemical reaction. Thank you, Ethan, for an AWESOME experiment!

Super Scientist Brooks did a great experiment about surface tension. He used half and half milk and then had each student drop different colors of food coloring on top. He did not mix it up. Instead, he poured drops of dishwashing liquid on the drops of food coloring. Immediately, we could see the milk swirl the colors together. It was very cool to see the various colors forming as they were mixed. The class also thought it was neat that it continued to swirl all day on its own. Awesome experiment, Brooks!

Super Scientist Madison from Mrs. C’s Class

Super Scientist Madison did a cool experiment with eggs! She had the class predict which egg would spin faster: a hard-boiled egg or a raw egg? She then spun the eggs at the same time…the boiled egg spun faster! The raw egg’s center of gravity changes as the white and yolk move around inside the shell, causing the wobbling motion. The boiled egg spins faster because it is solid! Great job, Super Scientist Madison!

Super Scientist Lenwood taught us how to make a rocket propel. He brought in Alka-seltzer tablets cut in half, a bottle of water, and a film canister made into a rocket. He placed a little water in the canister with half of Alka-seltzer tablet. He put the lid tight and placed it on the ground. We watched the rocket propel 3 feet in the air. He did this a couple of times. The rocket propels when the water and the alka-seltzer combine. The pressure from the carbon dioxide forces the top to pop off so the gas can escape. Then the rocket is propelled upward. They loved seeing this experiment.

Super Scientist Jenna in Mrs. P’s class

Super Scientist Jenna did a great job teaching us about density. She brought in two cups, two eggs, and some salt. She placed one egg in a cup of water and the egg sunk to the bottom. She added salt to the other cup of water and then dropped the egg in the cup. The salt made the water denser so the egg floated! We learned that the denser or thicker the water the better the chance the egg will float. Great Job!
