Kids for Conservation Lesson 1
Third graders observe various demonstrations dealing with the water on our earth, such as a comparison of the amount of salt water and fresh water on earth, then participate in a role playing activity in which they become a molecule of...
Curated OER
Science: Quick Freeze
Students observe an experiment of freezing point depression using club soda. Through observation, they note that the carbon dioxide molecules disrupt the capacity of the water molecules to solidify. Precautions must be taken to assure...
