Demos & Experiments

In this lab activity, students investigate how to prepare a biofuel source for conversion to a combustible product. The activity models how raw materials are refined to process liquid fuels.

This model of ocean-atmosphere interaction shows how carbon dioxide gas diffuses into water, causing the water to become more acidic. The video demonstration and instruction provide an explanation of the chemistry behind this change and the consequences of ocean acidification. The video also addresses a misconception about how ocean acidification affects shelled organisms.

Carbon cycle activity to demonstrate how carbon moves throughout the atmosphere. The activity ends with a discussion of how humans impact the carbon cycle.

This is a simple but effective scientific experiment to study the impacts of temperature and salinity on water density.

Students act out 4 different molecules (nitrogen, oxygen, carbon dioxide and water vapor) to discover which ones are greenhouse gases and which ones are not.

This is a kinesthetic activity that demonstrates how shortwave radiation emitted by the sun and longwave thermal radiation emitted by the earth interact differently in the atmosphere. It allows students to experience this difference and reinforces their understanding of greenhouse gases as well. Students should have an understanding of shortwave and longwave thermal radiation and of greenhouse gases before doing this activity, but there is a minimal amount of background information about those topics included in this pdf. Additional resources and background information for teachers can be found on the website for the Little Shop of Physics.

Children use a toaster to generate wind and compare the appliance's heat source to Jupiter's own hot interior. They discover that convection drives wind on Jupiter and on Earth.

Children test how cornstarch and glitter in water move when disturbed. They compare their observations with videos of Jupiter's and Earth's storm movements.

This activity includes two experiments that explore shadows and light and how mirrors can demonstrate how light travels.

In this activity, students make and manipulate physical shoreline models to discover the features of resilient shorelines and to critically evaluate the impacts of rising seas. Students will use NOAA's Sea Level Rise Viewer to observe a coastal area of interest and predict the consequences of sea level rise on people, the environment, and the economy. Though the curriculum references North Carolina, this lesson will work for all coastal areas.
