In this outdoor activity/field trip, learners investigate organisms that live along the ocean's rocky coast.

This fun and simple hands-on astronomy activity lets learners explore model planets (that they or an educator will create), using methods NASA scientists use to explore our Solar System.

In this seismic simulation, learners play a "who-dunnit" game to explore earthquakes.

In this activity, learners construct a coastal landmass from sand and add features such as tidal creeks and barrier islands.

In this activity, learners observe live fish in tanks to consider how their body structures are related to their behaviors and habitats.

Many of the genetic sequences found in the fruit fly genome are similar to those found in humans.

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.

In this activity related to plant biotechnology, learners transform a strain of E. coli using green fluorescent protein from a bioluminescent jellies.

In this online activity, learners build their own system of heavenly bodies and watch the gravitational ballet.

In this outdoor activity and observation game, learners hunt for a variety of textures, colors, odors and evidence of organisms in the activity site.

Yes, you can weigh your car by figuring out your wheel's tire pressure combined with the "tire's footprint." You'll need someone with a car, driver's license, and safety in mind.

In this experiment related to plant biotechnology, learners discover how to prepare and load an electrophoresis gel.

In this data analysis and environmental science activity, learners evaluate the feasibility of wave energy as a practical alternative energy source using ocean observing system (OOS) buoys.

In this activity (pages 5-7), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.

In this activity, learners identify different classes of matter based on physical properties.

This fun hands-on astronomy activity uses a variety of simple props to help learners understand why they see what they see in a telescope.

This paper describes a working-model demonstration of Ernest Rutherford's 1911 experiment about the nature of atoms.

This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.

In this activity, learners determine the elastic and plastic properties of different types of metal wires.

In this optics activity, learners explore interference by adding wax blocks to a ripple tank.
