In this activity, learners build a tool called an inclinometer that can find the height of any distant object, from a tree to the North Star.

In this activity, learners measure the diameter of their water balloons, model an impact, measure the diameter of the “crater” area, and determine the ratio of impactor to crater.

In this health and fitness activity, learners focus on the importance of daily physical activity, specifically walking.

In this activity, learners measure the amount of carbon dioxide in a carbonated drink.

In this activity, learners explore how engineers use scales and measures when designing a manufacturing process to ensure that final products are uniform in weight or count.

In this activity (page 2 of PDF under GPS: Glaciers Activity), learners will measure the rate at which water streams out of a leaky cup.

The demonstration/experiment provides quick proof that air has mass.

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

In this activity, learners will be working with predictions with a time frame of one week, or longer. Start by planting seedlings.

In this math-based activity, learners model the intensity of light at various distances from a light source, and understand how astronomers measure the amount of sunlight that hits our planet and othe

In this environmental health activity, learners investigate their own vital lung capacities.

This is an activity about turbidity, or the amount of sediment suspended in water.

In this experience, learners use the internet to research physical details about Chihuly's Fireworks of Glass "Tower" and "Ceiling" and consider the decisions Chihuly had to make as he was planning th

Learners add calcium chloride to a baking soda solution and observe an increase in temperature along with the production of a gas and a white precipitate. These are all signs of a chemical reaction.

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

In this activity, learners explore dinosaur skeletons and anatomy. Learners make observations about a T. rex skeleton diagram and then measure the skeleton length and width.

In this activity, learners "go fishing," then practice ruler use and size/pattern comparison with the animals they catch.

In this outdoor water activity, learners explore how to change the direction of water flow. Learners make puddles in dirt or use existing puddles and sticks to make water flow.

In this meteorological activity, learners get to build their very own anemometer (instrument for measuring wind speed) using a paper cup.

In this quick activity, learners drink Avogadro's number worth of molecules - 6.02x10^23 molecules!
