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 activity (on pages 24-34), learners explore the four-part stomach of cows (and other grazing animals called ruminants), and compare it to the human one-part stomach and its digestive process.

This is an activity (located on page 3 of the PDF under Water Clean-up Activity) about the use of reduction agents to decontaminate ground water.

In this activity, learners discuss the different salinities of oceans, rivers and estuaries.

In this activity, learners explore the economics of coal mining as you they use fake money to purchase mining tools, attempt to carefully mine their cookies, sell their chocolate chip ore, and try to

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.

This is an activity which will allow learners to gain an understanding of lemur behavior through observation and role play.

In this online Flash game, learners will explore a coral reef using an underwater remotely operated vehicle (ROV).

In this team design challenge (page 19-24 of PDF), learners "land" a model Lunar Rover in a model Landing Pod (both previously built in activities #3 and #4 in PDF).

This activity uses Jell-O(R) to introduce learners to microfluidics, the flow of fluids through microscopic channels.

In this activity, learners explore the engineering design process (EDP)—the process engineers use to solve design challenges.

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 perform an experiment that replicates the dilemma faced by birds in acquiring food from a confined area.

This is an activity about the adaptations that allow the Aye-aye to survive in its habitat. Learners will explore how the Aye-aye collects food and how this is influenced by their specialized finger.

In this simulation, learners use M&M™ candy to explore radioactive isotope decay.

In this lesson that includes hands-on activities and demonstrations, learners discover that it is the tilt of the Earth's axis (not its proximity to the sun) that causes the seasons.

In this activity (25th on the page) about learning and memory, learners explore a training method that animal trainers employ called "shaping." Working in pairs, learners will attempt to "shape" each

In this environmental science activity about biodiversity, learners play a game to discover the effects of non-native species on an ecosystem.

In this yummy biology activity (page 3 of the PDF), learners participate in a demonstration of natural selection.

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