In this activity, learners will listen to as many radio stations as possible to discover that AM radio signals can travel many hundreds of miles at night.

In this activity, learners simulate a multistage rocket launch using party balloons, fishing line, straws, and a plastic cup.

This fun and simple hands-on astronomy activity lets learners experiment with a bucket, stretchy fabric, marbles, and weights to discover some basics about gravity.

In this activity, learners make a model of a pollution spill that occurred at Bangs Lake in Mississippi and measure water quality parameters in their model.

In this activity, learners conduct a simple experiment to see how electrically charged things like plastic attract electrically neutral things like water.

In this design challenge activity, learners explore the concept of biomimicry by using a natural organism's special features to design a new human object.

This fun and simple hands-on astronomy activity describes techniques scientists use to find planets orbiting other stars.

In this activity, learners use basic measurements of the Earth and pieces of rock and iron to estimate the mass of the Earth.

Learners measure irregularly shaped bones using a variety of measurement methods and tools. Then, they measure again using standard conventions and metric tape measures.

In this activity, learners imagine what the world might look like if we could build an elevator to space!

Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?

In this outdoor activity, learners race small boats, made of cork, balsa wood, popsicle sticks etc., to investigate the rate and direction of currents in a stream or creek.

Based on color photographic images, learners compare geological features on Earth and Mars to understand similarities and differences between the two planets, and consider the forces that created land

In this activity, learners make their own pinhole viewer in order to measure the size of the sun.

In this activity, learners use sand and ice cubes to create a model of permafrost and the effects of the ice melting through the surface.

In this activity, learners explore the magnetic field of a bar magnet as an introduction to understanding Earth's magnetic field. First, learners explore and play with magnets and compasses.

In this activity you'll see how the sun's tilt on its axis changes the length of shadows. For example, why is your shadow longer in winter than in summer?

In this activity, learners will explore trends in shark populations using shark landing data from the National Marine Fisheries Service.

In this sunny day, outdoor activity, learners observe changes in shadows over time. The activity also helps to develop a sense of the Earth's motion.
