We are learning about Matter during science. We have done 2 cool experiments so far.

Mixing Solid and Liquid

Students experimented with adding drops of liquid (vinegar) to solids (flour, sugar, salt, baking soda). They used a pipette (dropper) to drop a little liquid at a time. We took time to observe and record what happened.  The most exciting step was watching the gas bubbles created when the vinegar was added to the baking soda.

Balloon Blow-Up

Our next experiment was to see if we could harness the gas created by mixing vinegar and baking soda and use it to inflate a balloon.  It worked! We tied off the balloon and noticed that the gas was very dense because the balloon dropped quickly to the floor compared to a balloon filled with air.

We have one more experiment planned for next week.  Stay tuned!
