In this activity, learners cut wells in JELL-O© and load the wells with different detergent solutions.

As a group, learners investigate three packages which are all the same size and shape, but have different contents. One is filled with foam, one is filled with wood, and one is filled with metal.

In this design challenge activity, learners use two helium-filled balloons to build a blimp that can travel in a straight path across the room.

In this activity related to magnetism and electricity, learners observe as two parallel, current-carrying wires exert forces on each other.

In this game, learners cross off or color bingo squares in response to questions about their traits.

In this activity (on pages 15-18 of PDF), learners make a life-size two-dimensional paper model of their own skeletons.

In this activity learners will investigate magnetic and non-magnetic items in a sensory bottle.

In this activity, leaners will observe the process of natural selection on a population of birds called 'Springbeaks' over four seasons of breeding on an isolated environment called 'Clippy Island.' L

In this two-part activity, learners work in pairs to examine the four basic stages of a turbine engine.

Break open that used musical toy and squish some Play-Doh over the circuit boards, and you will hear some weird and distorted sounds the manufacturer never intended!

In this math lesson, learners participate in several activities where they apply measurement skills.

Many common household cleaners are antimicrobials.

In this activity, learners explore the design of tall structures such as skyscrapers and telecommunication towers.

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.

Learners explore the Bernoulli effect by building an airfoil (airplane wing) and making it fly.

Through this nutrition activity (page 5 of the PDF), learners will understand—and probably be surprised by—how big serving sizes of various foods should be.

By playing a card game similar to "Go Fish," but based on the stages of metamorphosis, learners will be able to see how insects change in form as they grow and will consider the advantages of undergoi

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.
