In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

Demonstrate the Bernoulli Principle using simple materials on a small or large scale.

In this activity, learners perform an experiment to find out what determines a flower's color.

In this demonstration, learners observe vinegar and baking soda creating carbon dioxide (CO2) in a bottle. The gas is poured out of a bottle onto a candle flame, putting out the candle.

In this activity, learners create a model using metric measuring tapes and atmosphere composition data.

In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.

Learners color and cut out a spiral-shaped snake. When they hang their snake over a radiator, the snake spins.

Learners see convection currents in action in this highly visual demonstration. Sealed bags of colored hot or cold water are immersed in tanks of water.

In this demonstration, learners observe vinegar and baking soda reacting to form carbon dioxide (CO2) gas.

Learners cover a bottle with a balloon. When they immerse the bottle in warm water, the balloon inflates. When they immerse the bottle in a bowl of ice, the balloon deflates.

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

Learners develop an understanding of air pressure in two different activities.
