In this activity, learners will discover how to make butter from scratch. One optional tips includes adding marbles to speed up the process.

After learning that some of the chemicals we add to food crops may have harmful consequences on our health and the health of the environment, learners will create a pocket-sized card with their favori

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 activity, learners of all ages will design a functional bird feeder using familiar, every day materials.

In this activity (located on pages 23-24 of the PDF), learners are introduced to structural engineering and encouraged to practice goal-oriented building.

No glue is needed for learners of any age to become marshmallow architects or engineers.

In this activity, learners will explore nature by creating food for birds. Learners will develop fine motor skills and engage in nature observation through this activity.

In this engineering activity, learners investigate the differences between the strength of bridges made from flat and round building materials.

Learners build structures from spaghetti and marshmallows to determine which structures are able to handle the greatest load.

In this quick SciGirls activity (page 1 of the PDF under SciGirls Activity: Doghouse Design), learners will be introduced to the concept of thermal conductivity.

Learners work in groups to construct bridges using stale marshmallows and toothpicks.

In this activity, learners transform everyday milk into small plastic figurines and jewelry. Use this activity to introduce learners to monomers and polymers.

This is an activity that demonstrates how batteries work using simple household materials. Learners use a pickle, aluminum foil and a pencil to create an electrical circuit that powers a buzzer.

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 use molecular model kits to construct familiar molecules like lactose, caffeine, and Aspirin.

In this design challenge, learners use their creativity and imagination to design and test a wildlife crossing for their favorite animal.

In this simulation, learners use M&M™ candy to explore radioactive isotope decay.

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

This is an activity (on page 2 of the PDF under Surface Area Activity) about surface area to volume ratio.

In this activity, learners are challenged to design and build the tools they need to survive being shipwrecked on a deserted island.
