In this activity, learners explore Charles' Law in a syringe.

Historically, sea floor mapping (bathymetry) was done by soundings.

Using simple, inexpensive items, learners build and test submarine models.

In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.

In this activity, learners investigate the concepts of relative size and distance by creating a basic model of the solar system.

In this water pollution activity, learners create pond water cultures and investigate the effects of adding chemicals or natural nutrients.

This activity offers learners and their families several ways to raise their awareness together about home water.

In this activity, learners make an astrolabe, a device used for measuring altitude, including the height of objects in the sky.

In this three-part activity, learners play a game and conduct two simple experiments to explore water and surface tension. Learners will have fun discovering how water "sticks" together.

In this activity, learners explore dinosaur fossils and skeletons. First, learners listen to "Tyrannosaurus Rex" by Daniel Cohen to learn about T. rex dinosaurs specifically.

Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

In this activity, challenge learners to predict and investigate how many water drops they can fit on one penny.

This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection by encouraging them to formulate questions that can be answered through scientific investi

In this weather activity (page 10 of the PDF), learners will demonstrate the changes in atmospheric pressure by constructing their own barometer.

Get all wrapped up in a lesson about skin!

Learners take a field trip along a local body of water and conduct a visual survey to discover information about local land use and water quality.

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

In this activity, learners will investigate the impacts of harmful phytoplankton using NOAA's Coastal Services Center Harmful Algal Bloom Forecasting (HABF) Project data.

In this activity/demonstration, learners observe what happens when two ping pong balls are suspended in the air by a hair dryer. Use this activity to demonstrate how rain drops grow by coalescence.
