In this activity, learners explore how spring scales work and how they are used for non-exact weight measurement.

In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.

The goal of this activity is to design the fastest sailboat or one that carries the most treasure.

In this activity, learners explore how engineers incorporate biometric technologies into products as well as the challenges of engineers who must weigh privacy, security and other issues when designin

In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment.

In this environmental science and data analysis activity, learners work in groups to track a Dead Zone (decreased dissolved oxygen content of a body of water) using water quality data from the Nutrien

In a series of three experiments, learners explore the basics of biotechnology using self-locking plastic baggies. Each experiment demonstrates a phenomenon or principle of biotechnology.

April showers bring May flowers, but what do coastal storms bring?

In this activity, learners will use cereal to conduct an experiment and investigate how decreased bone density is related to increased risk of bone fracture.

This is an online game about stopping distance. Learners choose one of three vehicles and one of three speeds.

In this movement and measurement activity, learners jump as far as they can three times, and compare their longest jump to the longest jump of their friends, classmates and/or family members.

This is a quick and simple demonstration about reflexes (second activity on the page).

How far can you see out of the corner of your eye? Grab a partner and find out from the Exploratorium Science Snack.

In this activity, learners make critters out of recyclables and apply the rules of mathematics to solve genetics problems.

In this data analysis and environmental science activity, learners examine the effects of pollution on amphipods using data from the Chesapeake Ecotox Research Program.

In this activity, learners investigate the food, water, and space needs of common livestock animals.

In this activity, learners balance chemical equations and discover the law of conservation of mass. Learners use coins to model molecules to balance the equations.

In this activity, learners make a small batch of biodiesel that will work in any diesel engine. Learners use an old juice bottle as a "reactor" vessel to chemically process vegetable oil into fuel.

Here's a very simple activity if you have paper and scissors: make one cut, unfold, and you have a beautiful star! A great way to learn about polygons and origami mathematics.

In this lab (Activity #1 on page), learners compare bacteria growth on two petri dishes containing nutrient agar: one that has been touched by a finger washed only with water and one that has been tou
