Super Scientist Hannah!

Hannah was Super Scientist for Mrs. C’s class! She showed us how to make an exploding sandwich bag! Wow! First, she put 1/4 cup of warm water into the sandwich bag. Then, she added 1/2 cup of vinegar. Next, she put 3 heaping teaspoons of baking soda into a tissue. She folded the tissue up to keep the soda inside. She then quickly dropped the tissue into the bag and sealed it. The bag expanded until we heard a loud POP! It was awesome. The baking soda and vinegar mix to create an acid-base reaction. The two chemicals create a gas and fill the bag. When the bag can’t hold anymore gas…POP!

Way to go, Super Scientist Hannah!!!

Super Scientist Lanie

Lanie was a wonderful Super Scientist in Mrs. C’s class!

Super Scientist Lanie showed us an amazing explosion of color! Colors begin to dance when you mix a little milk, food coloring, and a drop of liquid soap. Lanie filled a dish with milk. Next, she added drops of food coloring. Last, she dipped a Q-tip covered with dish soap into the milk. The colors began to swirl and move in the milk. It made a beautiful tie-dye. The secret of the bursting colors is the chemistry of that tiny drop of soap. Dish soap weakens the chemical bonds that hold the proteins and fats in solution. This is when the fun begins with dancing colors in the milk!! Great job, Lanie!

Super Scientist Jarrett from Mrs. B’s Class!

 

 

Jarrett taught Mrs. B’s class about “Goo.” He mixed a borax solution (1 tsp. borax with 1 cup water) with a water solution (1/2 cup glue with 1/2 cup water and green food coloring) . He made a POLYMER because it can take the shape of its container like a liquid and you can pick it up like a solid. The students loved taking turns with the “goo.” Great job Super Scientist Jarrett!

Super Scientist Blake in Mrs. P’s Class

Super Scientist Blake taught us about sink and float.  He brought in a bowl with several objects from around the house.  We filled the bowl with water.  The students got to make predictions.  He then placed the objects in the water to see if we predicted right.  The students learned that the heavier objects sunk to the bottom while the lighter objects floated on the water.

Super Scientist Ava in Mrs. P’s class

Super Scientist Ava made a volcano explode.  She made the volcano out of clay and painted it brown.  She mixed baking soda, wat  er and dish soap in one bottle.  In another bottle, she mixed red food coloring and vinegar.  She poured them into the volcano.  The solutions made a chemical reaction.  The solution bubbled out the top.  The kids loved this experiment!

Super Scientist Zachary did an experiment for Mrs. W’s class called “Elephant Toothpaste.” He used water, yeast, hydrogen peroxide, food coloring, and dishwashing liquid. He mixed these ingredients in an empty bottle, and foam began to rise up and pour over the top of the bottle. It looked like a giant tube of toothpaste! Zachary let every child touch the foam. It felt a little warm because of the exothermic reaction when the yeast and the peroxide work together. This was SO cool, Zachary!
