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

Thumb Piano
Source Institutions
In this activity, learners explore sound by constructing a simple piano out of wood and craft sticks.

Greeting Card Boxes
Source Institutions
In this activity, learners make cool boxes out of old (or new) greeting cards or postcards.

Shrinky Dinks
Source Institutions
Heat makes some materials expand, and it makes others shrink.

Thrill Ride
Source Institutions
In this activity, learners will build a roller coaster for a marble to run on using everyday household materials such as paper towel or toilet paper rolls, cups, boxes, books, buckets, chairs, etc.

Hidden Color Chemistry
Source Institutions
In this activity, learners will discover what colors are in different markers, and may be surprised at the results.
Shadow Puppets
Source Institutions
If you have lights, cardboard, scissors, and some brass fasteners, you can make shadow puppets! Create a story-telling and design challenge for your learners with this simple and creative activity.

Lava Lamp
Source Institutions
In this activity, learners will create their own lava lamps. Learners will explore density, effervescence and chemistry through this activity.

Balancing Sculptures
Source Institutions
In this activity, learners will use a variety of household and/or natural objects to design a sculpture that balances from a single point.

Marshmallow Catapult
Source Institutions
In this activity, learners explore physics by building a catapult that launches marshmallows with household objects.

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

Squishy Letters
Source Institutions
In this activity, learners will practice writing while making a fun messy craft. Learners will explore texture and color as well as develop writing and fine motor skills through this activity.

Make a DNA Model
Source Institutions
In this activity, learners make a 3-D model of DNA using paper and toothpicks. While constructing this model, learners will explore the composition and structure of DNA.

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

Atomic Mobile
Source Institutions
Learners make a mobile model of a carbon atom using clay, wire, and pipe cleaners.

Jitterbugs
Source Institutions
In this activity, learners construct bug models that "jitter" all over the table with just a battery, motor, and counterweight.

Self-Portrait Silhouettes: Activity 1
Source Institutions
In this activity, learners make a photographic image--without a camera!

Moo Glue
Source Institutions
Using a milk-based recipe, learners create "moo glue" which is basically white school-type glue. The "secret ingredient" in milk that helps make glue is a chemical called casein.

Fly a Hot-Air Balloon
Source Institutions
Learners assemble a hot-air balloon from tissue paper. The heated air (from a heat gun) inside the balloon is less dense than the surrounding air and causes the balloon to float.

Cupcake Delivery
Source Institutions
In this design challenge, learners will create wind-powered contraptions to transport a load, such as a cupcake or another small object, and test to see if they work.
