Hot Stuff!: Investigation #2
Learners test two jars containing hot water, one covered with plastic and one open, for changes in temperature.

Finding the Size of the Sun and Moon
Source Institutions
In this activity, learners build a simple pinhole viewer. They use this apparatus to project images from a variety of light sources, including a candle, the Sun, and the Moon.

Mechanical Madness
Source Institutions
In this online Flash game, learners test their engineering know-how, moving a collection of mechanical parts onto a board to make complete a system of parts that will move a ball from start to finish.

New Boxes from Old
Source Institutions
Learners determine the surface area and volume of two identical boxes, and then figure out the dimensions of a cubical box with the same volume.

Parachute Parade
Source Institutions
In this engineering activity, learners design parachutes to give toy figures safe landings. This activity is great for practicing an important STEM skill--changing only one variable at a time.

Read Without Seeing
Source Institutions
Learners write a message in Braille using beans to form the patterns of dots. Learners glue beans in place, and then challenge another learner to read the message.

Using Different Models of Earth
Source Institutions
In this activity, learners explore how the shapes, sizes, and distances of land masses appear differently on two different models of Earth: an icosahedron and a flat map.

Paper Table
Source Institutions
In this design challenge activity, learners use tubes of newspaper to make a table that’s at least eight inches tall and strong enough to hold a heavy book!

Super Golf Tower
Source Institutions
In this engineering activity, challenge learners to build a tower out of 10 sheets of newspaper and 3 feet of masking tape, which can hold a golf ball balancing at the top.

Gecko Feet
Source Institutions
This is an activity (located on page 3 of PDF under Gecko Feet Activity) about modeling a nanoscale phenomenon (gravity-defying gecko feet) with macroscale objects (shoes).

Glider
Source Institutions
In this activity, learners construct paper airplanes that twist and turn.

Cup Draw (Low Tech)
Source Institutions
In this activity, learners construct drawing machines using a cup, some markers, and a battery pack. The markers act as "legs" for the machine, making a drawing that records as it moves.

Head, Shoulder, Knees and Toes...and Hands, Fingers and Back
Source Institutions
Are fingers the only place on the body where we use our sense of touch? In this activity (6th activity on the page), learners test the touch sensitivity of different parts of the body.

How Thick is Your Hair?
Source Institutions
In this activity on page 13 of the PDF, learners use a laser pointer (with known wavelength of light) to measure the thickness of a human hair.

Spool Racer
Source Institutions
In this physics activity, challenge learners to make a rubber band-powered spool racer. Demonstrate principles of motion as well as potential and kinetic energy.

Self-Assembling Dessert Toppings
Source Institutions
This is an activity (located on page 3 of the PDF under Self-Assembly Activity) about self-assembly, the ability of molecules to assemble themselves according to certain rules.

Find My Card
Source Institutions
In this activity, learners find the answer to the question, "if you have a pile of 8 cards, and you remove half, then half again, how many times can you do this until you get to just one card?" This w

Rubber Band Car
Source Institutions
In this design challenge activity, learners build a car that can travel at least four feet using rubber band power and use the design process to debug problems.

Exploring Products: Nano Fabrics
Source Institutions
In this activity, learners explore how the application of nano-sized "whiskers" can protect clothing from stains.

Cardboard Sculptures
Source Institutions
Learners explore the endless possibilities of cardboard engineering in this open-ended STEAM activity. Practice being creative by building structures with no glue, only cardboard and scissors.
