In this activity (on page 146 of the PDF), learners will explore the effects of increased carbon dioxide in the bloodstream.

In this activity, learners will exercise their imaginations and artistic skills. Appropriate for all ages, learners will create unique pieces to jumpstart storytelling sessions.

In this activity, learners of all ages can become food scientists by experimenting with flour and water to make basic pasta.

From this How To slide show, you create an Audio Tape Bow that can play distorted audio sounds by running it across a tape head.

This lesson focuses on how to measure at the nanoscale and provides learners with an understanding how small a nanometer really is.

Put on a pair of gloves and be the conductor of your invisible orchestra!

In this activity, learners dissect a piece of pizza to learn about nutrients important for health.

In this activity (page 37 of the PDF), learners observe, on a prepared slide, muscle and spinal cord cells from a rat.

Learners apply their knowledge of heat transfer to design two cans - one that will retain heat and one that will cool down quickly.

In this outdoor, windy day activity, learners "fly" and race leaves along a line to discover which types of leaves catch the most wind. Which leaves are the best fliers? Why?

This activity (located on page 3 of the PDF under GPS: Balloon Fiesta Activity) is a full inquiry investigation into Bernoulli’s principle and airplane wings.

In this math lesson, learners use fruit to learn about proportions and percentages. Learners compare the weights of the edible and non-edible portions of fruit.

In this activity, learners use edible models of the DNA molecule to transcribe an mRNA sequence, and then translate it into a protein.

This paper describes a working-model demonstration of Ernest Rutherford's 1911 experiment about the nature of atoms.

In this activity, learners build models of comets, using edible materials, to learn about comets' structure.

In this activity, learners build edible models of DNA, while learning basic DNA structure and the rules of base pairing.

In this outdoor activity, learners measure familiar objects in nature to practice working with the metric system.

In this weather activity (page 4 of the PDF), learners will explore the water cycle through an interactive game.

In this outdoor simulation game, learners search for pretend animals called "sticklers" to determine and map where they live (habitat) and how spread out they are in that area (distribution).

In this design challenge activity, learners add a jet-propulsion system (i.e. a balloon) to a blimp so it flies straight and far under its own power.
