Finishing Up Chemistry

Finishing Up Chemistry

School's out, but LHS students in Mrs. Brown's chemistry classes finished up the school year with dry ice experiments. The dry ice (solid carbon dioxide) changes rapidly back to its most stable form which is a gas, and this change is called sublimation. There are several safety concerns that should be observed when working with dry ice such as not putting it into enclosed containers, not consuming it, not handling it with bare hands, and not inhaling it. Classes discovered why each of these precautions exist. They also experimented with acid/base indicators to see how the CO2 would affect them and created dense bubbles full of CO2 gas. Mrs. Brown, you are amazing, and thank you for all the extra things you teach our lucky kids! You're in the right place!
