Using electrolysis, learners produce hydrogen gas and oxygen gas from water molecules in a solution.

In this activity, learners explore trebuchet design. Teams of learners construct trebuchets from everyday materials.

In this two-part activity, learners map a navigation plan to get from Earth to Mars and back. In activity one, learners represent the orbital paths of Earth through dance and dramatic movement.

In this activity, learners are challenged to calculate their own weight on various planets using a scale and calculator. Older learners may be challenged to do so without using calculators.

In this activity, learners will perform various investigations to understand the vestibular-ocular reflex and learn about the importance of visual cues in maintaining balance.

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

This quiz lets you estimate your annual radiation exposure.

In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.

In this activity, learners are challenged to create a parachute using easily sourced materials in order to transport a LEGO figure safely to the ground.

In this activity, learners make a Benham Top to explore visual illusions and optics.

Learners add two dyes to mineral oil and water, and then compare their miscibility (how well they mix) in each.

This display shows the dangers of acid rain on buildings and other structures as two concrete bunny rabbits are disintegrated by sulfuric acid. Learners scrape chalk onto the concrete bunnies.

This game depicts a woman going through her day, faced with various loud sounds.

In this chemistry activity, learners transform two ingredients (4% polyvinyl alcohol solution and 4% borax solution) into gooey slime.

In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

In this activity and/or field trip, learners investigate the water currents that aquatic animals create when they breathe, feed, and propel themselves through water.

In this activity, learners explore how spring scales work and how they are used for non-exact weight measurement.

In this activity, learners explore how engineers work to solve the challenges of a society, such as delivering safe drinking water.

Exponga estos pósteres en el salón o déjelos donde los chicos los puedan explorar. Los chicos buscan las respuestas en libros de consulta, explorando el salón, y usando su creatividad.

In this activity, learners explore how engineers work in a team to solve problems.
