In this activity, learners use multiple thermometers, placed at different angles, and a lamp to investigate why some places on Earth's surface are much hotter than others.

This is an activity about waves. Using marbles, paper clips and rubber bands, learners explore how waves behave.

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

In this physics activity (page 8 of the PDF), learners will make their very own working compass.

In this physics activity, learners build their own rockets out of film canisters and construction paper.

In this activity, learners discover the difficulty of ocean exploration by human beings as they investigate water pressure.

Many people get water from a source deep underground, called groundwater.

What causes frost to form on the outside of a cold container? In this activity, learners discover that liquid water can change states and freeze to become ice.

In this quick activity (located on page 2 of the PDF under GPS: Balloon Fiesta Activity), learners will see the effects of convection and understand what makes hot air balloons rise.

In this activity about magnetism (page seven of the pdf), learners experiment with magnets to better understand how magnetic fields work.

In this meteorological activity, learners get to build their very own anemometer (instrument for measuring wind speed) using a paper cup.

In this activity, learners explore the relationship between cooling water vapor and condensation. Learners investigate condensation forming on the outside of a cold cup.

This is an activity about rockets. Learners will explore how rockets leave Earth's orbit and what it takes to make a launch successful.

In this activity about water solubility and density, learners use critical thinking skills to determine why water can dissolve some things and not others.

In this three-part activity, learners play a game and conduct two simple experiments to explore water and surface tension. Learners will have fun discovering how water "sticks" together.

Glare from the sun and ripples from the wind can make it hard to see what's below the surface of a body of water.

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.

Learners investigate how the temperature of water affects its density.

This fun and simple activity is a rubberband rocket design challenge! Learners will explore how tail fins can help to stabilize a flying object, while also exploring potential and kinetic energy.
