Just as the increase in atmospheric CO2 is causing the global air temperture to rise, the container with the added CO2 will trap more heat inside and will show a higher internal temperature.
Overview
This activity/demonstration can be used directly following lessons on greenhouse gasses and their effects on warming the atmosphere by allowing shortwave UV energy
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
