Throw that fish back? A new generation of ethical anglers concerned about conserving resources is participating in "catch and release" fishing. How is this going?

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

In this activity, learners can create five-layer density columns by employing one of three (or all) methods.

In this activity, learners explore how to stay fit the fun way. Learners participate in three physical activities.

In this activity, learners (at least three) work together to explore the effects of atmospheric pressure.

In this robotics activity, learners find ways to express emotions and feelings using only body movements, not facial expressions.

In this optics activity, learners explore color by examining color dots through colored water and the light of a flashlight.

This is an activity about prediction. How far can you hop in 5 seconds? Could you make it to the door? Across the room? Everyone lines up and tries it.

In this activity, learners eat a snack and make a model of the plumbing system of a volcano.

In this data activity, learners will compare and contrast fish communities, diversity and habitats in U.S. National Marine Sanctuaries.

In this outdoor activity and game, learners explore how animals adapt for survival through coloration, markings and camouflage.

This activity allows learners to explore the scientific method in an open-ended fashion, using the 4-P Approach to Science Inquiry developed by the University of Wisconsin, Beloit.

In this optics activity, learners explore how light bends and affects what we see.

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

In this activity, learners use their feet to estimate distances. Learners calculate the distance of one step in centimeters by measuring 10 steps at a time to reduce measurement error.

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

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 group activity, learners use some common objects and work together to simulate the Coriolis effect. During the challenge, learners make predictions and test different scenarios.

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

In this activity, learners explore the structure of plant leaves. Learners find out what happens when they coat either the top or bottom sides of leaves with petroleum jelly.
