In this activity (located on pages 9-14 of PDF), learners visit a cemetery to examine the distinguishing characteristics of rock weathering.

In this activity, learners explore clouds and how they form.

Learners build a simple aneroid barometer to learn about changes in barometric pressure and weather forecasting. They observe their barometer and record data over a period of days.

Learners color and cut out a spiral-shaped snake. When they hang their snake over a radiator, the snake spins.

In this activity on page 27, learners perform an experiment to learn about how different types of marine debris degrade and how weather and sunlight affect the rate of degradation.

Learners see convection currents in action in this highly visual demonstration. Sealed bags of colored hot or cold water are immersed in tanks of water.

Learners cover a bottle with a balloon. When they immerse the bottle in warm water, the balloon inflates. When they immerse the bottle in a bowl of ice, the balloon deflates.

Learners complete a series of hands-on and investigative activities to explore cumulus clouds.

In this activity, learners investigate soil conditions by creating a soil map. Learners record soil characteristics and compare the conditions of soil in different grid sections.

This warm weather activity introduces learners to the impact trees have on blocking the sun's heat and reducing temperature on the Earth's surface.

In this activity, learners play a game to simulate the food chain.

In this activity, learners construct a coastal landmass from sand and add features such as tidal creeks and barrier islands.

In this activity, learners model a population of deer and see how the number of deer changes over time.

In this activity, learners gain knowledge about how carbon moves through all four of the Earth’s major spheres (biosphere, hydrosphere, atmosphere, and lithosphere), and understand how humans influenc

Learners investigate the concept of humidity by using a dry and wet sponge as a model. They determine a model for 100% humidity, a sponge saturated with water.

In this "Sid the Science Kid" activity, learners set up a simple experiment to find out how sunscreen counteracts the effects of the sun.

In this activity, learners create a biosphere in a baggie.

In this outdoor, warm weather activity, learners use sweepnets to search a grassy area such as a large lawn or field, collecting small animals to find as many different kinds of animals as possible.

By participating in a seed scavenger hunt, learners examine many adaptations of seeds, including how many seeds a plant makes, how those seeds travel to new locations, and what protects them from pred

In this activity related to climate change and data analysis, learners examine temperature and precipitation data to determine if climate variations are due to El Niño.
