In this activity, learners test different food items by timing how long it takes each liquid to slide from the top of a ramp to the bottom.

In this activity (on page 2 of PDF under GPS: Roller Coaster Design Activity), learners will use food cans of many different properties (sizes, shapes, and weights) and set two cans on their sides at

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

In this demonstration, adult learners create a lava lamp using beer and nuts! Use this pub-themed activity to demonstrate the effects of buoyancy and bubbles.

In this physics activity, learners attempt to lift a jar full of rice using only a spoon.

In this physics demonstration, learners are challenged to insert a straw the furthest into a potato.

In this activity, learners conduct a series of hands-on experiments that demonstrate how the working of plants' veins, known as capillary action, enables water to travel throughout the length of a pla

In this activity, learners investigate convection by using food coloring and water of different temperatures.

In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.

In this activity, learners build edible models of Jupiter and Earth to compare their sizes and illustrate the planets' internal layers.

In this quick activity (page 1 of the PDF under SciGirls Activity: California Fish), learners will build a simple Cartesian Diver in an empty 2-liter bottle.

In this collection of demonstrations, learners explore Newton's Laws of Motion.

In this activity, learners explore engineering package designs that meet the needs of safely shipping a product.

In this activity, learners use things from the kitchen as building materials to explore how shapes contribute to the strength of different structures.

In this activity, learners explore how product design differences can affect the success of a final product -- in this case a bag for holding candy.

In this activity on page 7 of the PDF, learners explore how engineers characterize building materials.

In this activity about engineering, nutrition, and physical activity, learners design and build a healthy bone model of a space explorer which is strong enough to withstand increasing amounts of weigh

Learners explore capillary action in plants (such as plants ability to move water from roots to leaves) in an investigation called Paper Blooms.

Learners develop an understanding of air pressure in two different activities.

In this activity on page 7 of the PDF (Water in Our World), learners make their own water treatment systems for cleaning water.
