In this environmental science activity (page 3 of the PDF), leaners will identify and explain the causes of erosion.

In this activity, learners will simulate the interactions between a predator population of gray wolves and a prey population of deer in a forest.

In this activity, learners discover how to determine the distance to a lightning strike or nearby thunderstorm.

This fun and simple hands-on astronomy activity lets learners create 3D models of the Earth, Moon and Sun to demonstrate solar and lunar eclipses.

In this outdoor beach activity, learners use a variety of "beaks" (such as trowels, spoons or sticks) to hunt for organisms that shore birds might eat.

In this activity, learners investigate Scanning Probe Microscopes (SPM) and then work in teams using a pencil to explore and identify the shape of objects they cannot see, just as SPMs do at the nano

In this activity, learners pretend that they are orcas and search for their "pods" using Morse code.

Through doing these hands-on activities, learners explore the environmental consequences associated with fossil fuel usage.

This activity is about collecting and analyzing DNA as part of a criminal investigation.

In this activity, learners explore the engineering behind seismographs and how technology has improved accurate recording of earthquakes.

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

In this activity, learners experiment and collect data during a simulation of the fluid shifts experienced by astronauts' bodies in microgravity.

In this pencil and paper activity, learners work in pairs and simulate how astronomical spacecraft and computers create images of objects in space.

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

In this activity, learners help a poor cartographer color in the countries on a map, making sure each country is colored a different color than any of its neighbors.

This fun and simple hands-on astronomy activity lets learners explore what happens when a star explodes.

In this activity about computer programming, learners follow instructions in a variety of ways in order to successfully draw figures.

In this wintertime outdoor activity, learners role play wolves tracking their prey by following scented trails.
