Source Institutions
Have you noticed the plastic rings that are used to hold six-packs of soda? Those rings are great for carrying cans, but they're real trouble when they become trash that animals can get tangled in.

Irrigation Ideas
Source Institutions
In this activity, learners explore how civil engineers solved the challenge of moving water via irrigation.
Magnus Glider
Source Institutions
A design challenge that takes paper airplanes into an entirely different direction: a magnus glider uses cups and and rubber bands to create a glider that uses the same forces that a curveball (from b

Give Me a Brake
Source Institutions
In this activity, learners explore the concept of how brakes can stop or slow mechanical motion.

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.

Tricky Tangrams
Source Institutions
In this activity (on pages 49-54 of PDF), learners play with tangrams, a set of triangles, squares and a parallelogram that can combine into a larger square as well as all sorts of other shapes.

Coral Snapshots: Biodiversity in Marine Protected Areas
Source Institutions
In this data activity, learners analyze data from coral reef snapshots taken by scientists at the Virginia Institute of Marine Science.

Build Your Own Solar Oven
Source Institutions
Learners follow directions to construct a solar oven that really cooks! The solar oven uses aluminum foil to reflect sunlight into a cooking chamber, which is painted black.

Paper Cup Stool
Source Institutions
In this activity, learners will explore how and why weight distribution works.

Strong Shapes
Source Institutions
Is a square stronger than a triangle? Use tongue depressors to build simple shapes. Then apply a little weight to them and see what happens!
Size Them Up: Learning About Volume and Capacity
Source Institutions
In this activity, learners will put a set of containers in order by capacity. Would the tallest container hold more or less water than the wide, short one?
Fair Shares: Predict Equal Shares
Source Institutions
Use this activity to build division and number sense into any snack time or whenever there is a limited set of things to share among a group: If we deal these out, could everyone get two pieces?
Leaves: Designing Leaf Arrangements on a Branch
Source Institutions
In this hands-on activity, learners investigate the functional design of leaves on a tree.

Paddle Power
Source Institutions
In this design challenge, learners build a boat that paddles itself using a rubber band as its power source.

Wet Art
Source Institutions
In this activity (located on page 10 of the PDF), learners explore the properties of spraying and dripping water, while making art.

Hidden Alarm
Source Institutions
In this design challenge activity, learners invent a device that will make their friends and family ask, "What's buzzing?" Learners design an alarm with an on/off switch that is small enough to hide.

Non-Round Rollers
Source Institutions
Wheels aren't the only things that can "roll" objects that are placed on top of it. Make non-intuitive shapes from cutouts and a compass to demonstrate this.

Treasure Hunters
Source Institutions
Learners use their opponent's clues and a compass rose to find the hidden treasure on a map. Learners use problem solving and coordinate grid skills as they hunt for treasure.

Two Sets!
Source Institutions
In this card game, learners make two sets of three cards that are alike. Learners must justify to the rest of the players why the three cards belong in each set.
Number Flips
Source Institutions
In this math activity, learners play a number game to explore the relationships between numbers, combinations, and the concept of equivalency.
