In this activity, learners heat and cool carbonated water to find out whether temperature has an effect on how fast the dissolved gas leaves carbonated water.

In this activity, learners play a game and use pattern blocks to explore mirror images and reflection.

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 activity, learners build a paper model of the spacecraft and photometer (telescope) used during NASA's Kepler Mission.

With a straw, two craft sticks, and some rubber bands, construct a noisemaker called a Sound Sandwich and explore how vibration produces sound.

In this activity, learners use a toaster to generate wind and compare the appliance's heat source to Jupiter's own hot interior. Learners discover that convection drives wind on Jupiter and on Earth.

Learners imagine they are paleontologists in Florida, where they find (remove from envelope) paper "fossils" of some unknown creature, only a few at a time.

In this activity, learners place cards featuring biological structures in order by their relative size from largest to smallest.

In this activity, learners will create unique rockets. Each rocket will be powered by air as the learner will blow into a straw and watch their rocket fly.

In this physics activity, learners will investigate the strength of egg shells.

Learners turn over a random selection of cards from a larger set. From the words revealed, they try to determine the sentence represented on the larger set of cards.

In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.

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

Learners will explore the concept of angular distance, and investigate why the moon appears to be the same size as the sun during a solar eclipse, despite the sun being much larger.

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

This activity focuses on interactions within Earth systems and the effects of human activities. In this activity learners build a biomass pyramid.

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

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