To learn about the effects of air pollution on Sea Ice. This can be a library/computer lab-based activity.
Procedure
Teacher:
1. Mix up a 3.5% solution of NaCl. Make enough "sea-ice" cubes for each pair of students
2. Make another class set of ice cubes with tap water. Leave the ice in the freezer until after the
To compare the conductivity of freshwater and seawater. This is a lab activity, and students should be taught appropriate safety measures, including eye protection and safety while using electricity.
Procedure
1. Use the table in attached PDF to record your data.
2. Put 100 mL of 3.5% NaCl solution into a 250 mL beaker.
3. Attach 2
The Solar Oven Science activity was developed as a way to target conservation of energy. Some students understand that he sun can be used for heating and cooking but they mistakenly think that this can only work in deserts. Because of conservation of energy solar cooking and heating can work in temperate and even arctic environments. The linked
This activity is a way to create a cloud chamber in the classroom. A cloud chamber allows students to view "invisible" alpha particles emitted through nuclear decay. Alpha particles have a long history in nuclear physics--they are a helium nucleus and their emission during nuclear decay was one of the first ways we knew that atomic nuclei could
