Today, we began the long-awaited Chemistry unit! We are going to have so much fun in the next couple months as we explore what everything around us is made of and how things interact.
Our final lab was to make a substance to put out a fire. We mixed two common household substances--baking soda and vinegar--to create a gas, which was more dense than oxygen, and able to suffocate the candle flame. The wow factor, and relatively safe chemicals, made this a good lab to begin with. Everyone got a chance to try out the magic, and then we had a discussion about the density of carbon dioxide, and how you can detect the presence of a gas, even when it isn't visible. Our youngest mad scientists did a phases of matter sort for their notebooks, learned a song about the states of matter, and acted out how the molecules move in each state. They loved helping to create the fire extinguisher, too! Additional InformationVideos:
Phases of Matter: Bill Nye the Science Guy is back again, this time with a show on matter! Matter Song This one is a little different than the one the youngest class sang today, but similar. Activities: Make Oobleck Is it a solid? Or a liquid? With oobleck, it's hard to know! Read about this non-Newtonian liquid and make your own to play with. It just takes cornstarch and water. Experiment with the affects of temperature and pressure on water. All you need is an empty milk carton and hot and cold water for this demonstration.
