In this multi-step experiment (page 4 of pdf), learners study tide pools, and then drop a "wave" (a 4-pound bag of beans or birdseed) on a shell to mimic the force of crashing surf on tide pool animal

Learners identify an unknown liquid by comparing its behavior to known liquids. Learners drop liquids onto different surfaces and see how the liquids behave.

The Sacred Cenote at Chichén Itzá is a sink hole, or well, containing groundwater. In this activity, learners create their own cenote using chalk, limestone, acids, and rain water.

In this playful physics activity (page eight of the pdf), learners use toy cars to explore how speed and weight affect the results of collision.

In this fun sticker activity, learners will create a size wheel with images of objects of different size, from macroscopic scale (like an ant) to nanoscale (like DNA).

This kinesthetic science demonstration introduces learners to four states of matter: solid, liquid, gas, and plasma.

Learners discover that their breath contains carbon dioxide, one of the pollutants found in car exhaust.

This activity is designed to introduce learners to genes, genotypes and simple inheritance patterns.

In this activity, learners explore the web of connections among living and non-living things.

In this activity, learners design a scientific exploration mission to a planet or moon of their choice.

This activity (on pages 19-24) introduces learners to the rain forest's layers—emergent, canopy, understory, and forest floor—and has learners make paper lianas (vines that live attached to trees) and

In this activity (on page 2 of the PDF), learners explore surface tension by adding pennies to cups which are "full" of plain water or soapy water.

In this activity, learners can play two card games related to endangered species, specifically North American amphibians.

In this activity, learners cut, fold, and paste paper representing biomolecules to create a three-dimensional cell membrane with embedded proteins.

In this activity, learners will experiment to find how long it takes to compost paper. They will create their own compost container and test different variables.

In this activity, learners will design a seed and test how it travels. Learners will use the Engineering Design Process to create a seed which can move from place to place.

In this food science activity, learners observe different plant-originated foods.

In this environmental health activity, learners grow and observe bread mold and other kinds of common fungi over the course of 3-7 days.

In this math lesson, learners apply measurement skills to determine, in dollar bills, the capacity of a suitcase.

In this dynamic activity, learners build a catapult that launches projectiles, such as marshmallows.
