In this activity, learners discover how frogs' bodies change while growing from a tadpole to a frog. Learners create a simple craft that gives a visual display of the metamorphosis process.

In this activity, learners make models representing bones on Earth and bones that have been in space. They discover what happens to bones without proper exercise and nutrition.

In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.

In this activity, dry ice and other items are used to construct a demonstration model of a comet that illustrates the comet nucleus, coma, and tails.

In this activity, learners build a sled kite that models a type of airfoil called a parawing.

In this activity, learners will become an engineer by designing and engineering a miniature parachute.

In this activity, learners explore how casts of fossilized bones are created and used to learn about dinosaurs. Learners make observations, draw diagrams and share their findings.

In this activity, learners construct their own small catapults using simple materials. Learners follow visual instructions to build their launching device.

In this quick activity (page 1 of the PDF under SciGirls Activity: Tug O' War), learners will test how many pennies a flat paper index card bridging the gap between two stacks of books is able to supp

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

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 explore density and buoyancy as they design and construct rafts.

In this activity, learners act as the Earth and observe how different angles between the Sun, Earth, and Moon affect the phases of the moon we see each month.

In this activity, learners build a scale model of the solar system using a roll of toilet paper.

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 page 4), learners create a submarine using a plastic sandwich bag. This is a fun way to learn about buoyancy and how captured gas can cause objects to float.

With two stacks of books and a few rolls of pennies, build two kinds of bridges--a beam span and an arch span--and see how much weight each of them can hold.

In this activity (p.7-8 of PDF), learners examine fossil formation.

In this activity, learners will explore the dynamics of air pressure by using a candle, a cup, and a dish of water.

In this activity (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of information about
