In this activity about dinosaurs and survival, learners use scrap materials to create a miniature dinosaur habitat that includes a food source, water source, and shelter.

In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.

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

How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.

In this Engineering Design Challenge activity, learners will use balloons to investigate how a multi-stage rocket, like that used in the Interstellar Boundary Explorer (IBEX) mission, can propel a sat

This activity (on pages 23-27) lets learners simulate the work of scientists who take core samples of Earth's rocky layers to determine geological history.

In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.

In this space science activity, learners explore transits and the conditions when a transit may be seen.

In this activity, learners test how cornstarch and glitter in water move when disturbed. Learners compare their observations with videos of Jupiter's and Earth's storm movements.

In this activity, learners model hot spot island formation, orientation and progression with condiments.

In this activity, learners make a model of the solid Earth's layers that's good enough to eat! Learners use tasty foodstuffs to simulate Earth's inner core, outer core, mantle, and crust.

In this activity, two groups of learners create two separate landform models out of clay (mountains and valleys).

Learners model the Sun-Earth-Moon system to show what causes the Moon's appearance to change when viewed from the Earth.

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, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

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 (located on page 2), learners will construct tiny model geysers out of film canisters, warm water, and antacid seltzer tablets.

Learners model the ocean currents that carry hot water from the tropics to northern latitudes.

In this activity, learners observe colors in the flame of a burning candle to explore connections between matter, light, color and temperature -- basic concepts of matter and energy.

Learners build models of sinkholes to gain an intuitive knowledge of their physical aspects.
