In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

In this indoor and/or outdoor activity, learners make an anemometer (an instrument to measure wind speed) out of a protractor, a ping pong ball and a length of thread or fishing line.

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

This is a quick activity that shows how large amounts of rock and sediment are added to the edge of continents during subduction.

This activity gets learners looking at 6-sided shapes in nature, including the cells of a beehive, as well as other shapes.

In this kinesthetic activity, learners will play a game with a ball to demonstrate the Coriolis force, which partly explains why hurricanes in the Northern Hemisphere rotate counterclockwise.

In this activity, learners explore the engineering behind seismographs and how technology has improved accurate recording of earthquakes.

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

In this activity, learners explore how air warms when it condenses water vapor or makes clouds.

This is a culminating activity which allows learners to summarize what they know about Woodlands Native Americans by creating illustrations and map symbols for a large outline map (see related Activit

In this activity, learners will examine various world data maps to combine the information and predict which areas could be tropical rainforests.

In this activity, learners make their own "tornado" using two soda bottles and water.

In this activity, learners discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.

In this activity, learners discover the relationship between temperature and pressure in the lower atmospheres of Jupiter and Earth.

In this activity (on pages 12-15), learners make a crater model and test the effects of weather (rain) on its surface.

In this activity, learners investigate the Moon's infancy and model how an ocean of molten rock (magma) helped shape the Moon that we see today.

In this activity, learners discover that the Moon, like Earth, is made up of layers of different materials. Learners work in teams to make models of the interiors of the Moon and Earth.

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 observe the water cycle in action! Water vapor in a tumbler condenses on chilled aluminum foil — producing the liquid form of water familiar to us as rain and dew.
