In this activity (on page 1 of the PDF), learners make a "mini-globe" to investigate the causes of day and night on our planet.

In this activity (on pages 36-39), learners make a model of a watershed out of paper, then run water down the mountain to simulate how rainfall and pollution affect watersheds.

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

In this creative roleplay activity, learners will explore the various processes of the water cycle using movement, sound, and props to aid in comprehension.

Ancient trash tells archaeologists a lot about the past. In this activity, learners take a close look inside their trash can and think about the clues it offers about their lives.

In this outdoor winter activity, learners search for and create hibernation sites that will protect gelatin "animals" from freezing.

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

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

In this activity related to computer programming, learners give directions to a "robot" (either an adult or another learner) and find out which instructions the robot is able to follow, and how their

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

This activity (located on page 3 of the PDF under GPS: Farm Animals Activity) is a full inquiry investigation into raising livestock.

This fun and simple hands-on astronomy activity lets learners explore the difference between telescope magnification and resolution.

Learners create three solutions with different levels of salinity. They compare the density of these solutions by coloring them and layering them in a clear plastic cup and in a soda bottle.

In this activity, learners investigate soil erosion. Learners set up a simulation to observe how water can change the land and move nutrients from one place to another.

In this activity (on page 6 of the PDF), learners plot the path of the sun's apparent movement across the sky on two days, with the second day occurring two or three months after the first.

In this activity, learners are invited to imagine the park of their dreams!

In this quick activity, learners explore how blubber protects animals from the cold by making a "blubber mitt." Using cooking shortening, two zip-top sandwich bags, and duct tape, learners simulate bl

In this activity (page 5 of the PDF), learners will create a food web and explore food sources for different organisms. They will identify relationships between organisms in an ecosystem.

In this creative roleplay activity, learners will explore the various processes of the carbon cycle using movement and props to aid in comprehension.
