Freeze and Melt
Freeze tag! Have the class spread out around the playing area. Select some players to be freezers and un-freezers. Give freezers a blue ball and un-freezers a red ball. If a runner gets tagged with a blue ball, then they become a...

Please Pass the Salt
Salinity is the focus of two experimenters that work to answer the question, How does salt change the physical properties of water? Super scientists compare the freezing rate of salt and fresh water, combine the two waters to...

Introduction to Climate
Begin a full lesson on climate change by demonstrating how carbon dioxide gas contributes to increased temperatures. Be aware that pressure inside the antacid-containing bottle in Activity 2 may cause the lid to fly off; keep viewers at...
Curated OER
Icy Sun Catcher
Students fill the tray half full with water. In this art lesson, students lay the string in the tray and add little bits of little items. Students lay the tray outdoors on a cold winter night so that the water freezes. What is frozen...
Curated OER
Fun in the Sun
Students freeze colored water. In this art lesson, students take the blocks of ice out of the freezer, put the blocks into a small pool and watch the ice melt.

The Energy of Evaporation
Do all liquids evaporate at the same rate? Young scientists observe the evaporation rate of three different liquids. They measure the time, the temperature, and the change in energy. After comparing the chemical formulas, scholars...

Teach Engineering: What Is the Best Insulator: Air, Styrofoam, Foil, or Cotton?
That heat flows from hot to cold is an unfortunate truth of life. People have put a lot of effort into stopping this fact, however all they have been able to do is slow the process. Working in groups of three to four, students will...
