In this activity, learners discover the primary physical properties used to separate pure substances from mixtures.

This lab activity has learners create a pendulum with a one-second period.

Ocean acidification is a problem that humans will have to deal with as we release more and more carbon dioxide into the atmosphere.

Make your own speaker with a magnet, wire, and paper cup! If you have a radio with a headphone plug and an old pair of headphones, this is a great tinkering activity.

Learners use a variety of beans to represent a variety of species, and scatter these beans over a large piece of paper representing the environment.

In this activity, learners work individually to assemble a product and then work in teams to design, construct, test, and redesign an assembly line process whose product must meet specific quality con

Learners create a model of a wetland to observe how it absorbs and filters water from the environment.

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

In this Engineering Design Challenge activity, learners will use balloons to investigate how a multi-stage rocket, like that used in the Interstellar Boundary Explorer (IBEX) mission, can propel a sat

In this forensics activity, learners solve a mystery using “DNA” taken from the scene of the crime.

In this activity, learners use simple materials and basic tools to construct a special toy to explore pendulums. As the head of the toy bobs one way, the eyeballs bob the other way.

In this activity, learners construct speedy vehicles made out of paper plates and powered by twisted rubber bands.

In this activity (1st activity on the page), learners explore their sense of taste and the structure of the tongue by taste-testing various foods.

In this activity, learners will perform various investigations to understand the vestibular-ocular reflex and learn about the importance of visual cues in maintaining balance.

In this activity, learners carry out a scientific investigation of dust in their classroom. Learners produce an analysis on graph paper of the dust they collect over the course of a few days.

In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.

In this activity, learners observe colors in the flame of a burning candle to explore connections between matter, light, color and temperature -- basic concepts of matter and energy.

This game uses a modified Uno deck to review concepts related to stem cell research and diabetes.

In this activity (26th on the page), learners construct an easy-to-build device and test motor learning.

Learners build and investigate pendulums of different lengths. They discover that the longer the string of the pendulum, the longer the time it takes to swing.
