Learners recreate the classic egg-drop experiment with an analogy to the Mars rover landing. The concept of terminal velocity will be introduced, and learners perform several velocity calculations.

In this activity, learners will build the highest tower they can out of recycled materials.

In this activity, learners explore motion, energy, and electricity by constructing bottle cars that run on motors.

In this three-part activity, learners conduct simple experiments to see how light refracts and reflects, and how colors of light affect what we see.

In this activity (p.6-10 of PDF), learners use different methods for hunting minibeasts (bugs). Learners can either make traps or simply look for minibeasts under stones and logs.

In this activity (posted on March 12, 2011), learners follow the steps to construct a spectroscope, a tool used to analyze light and color.

In this activity, learners interpret three trackways and use measurements and a formula to infer the relative speed of dinosaurs.

In this activity (located on page 7 of PDF), learners explore how Silly Putty was first invented and then attempt to make a batch of their own.

In this activity, learners build small indoor paper rockets, determine their flight stability, and launch them by blowing air through a drinking straw.

In this activity, learners use aluminum trays and wooden blocks to form stream tables to investigate river formations in two different landscape scenarios.

In this astronomy activity (page 6 of the PDF), learners will compare and contrast two planets in the solar system using data obtained from the internet.

In this math lesson, learners explore transformations and quadratic functions through toothpick patterns.

In this simple chemistry activity (page 1 of PDF under SciGirls Activity: Colorblind Dogs) about acids and bases, learners will mix a baking soda and water solution and use it to paint a message on a

In this (edible) activity, learners balance chemical equations using different kinds and colors of candy that represent different atoms. Learners will work in pairs and explore conservation of atoms.

In this activity, learners will plan a snack within a budget. With a $20 limit (theoretical) to spend on snack for everyone, learners look over grocery store circulars and make their shopping lists.

In this math lesson, learners play a game to identify the properties of prime, composite, abundant, deficient and perfect numbers.

In this activity (on page 2 of the PDF under GPS: Luge Activity), learners will construct a model hovercraft out of an empty spool and a piece of cardboard.

In this activity related to climate change, learners examine albedo and the ice albedo feedback effect as it relates to snow, ice, and the likely results of reduced snow and ice cover on global temper

Learners build simple catapults and use them to launch cotton balls.

This activity provides instructions for learners to create models of the Earth and then to model a "day" on Earth as well as modeling the seasons.
