Paper Drop Design Competition
Source Institutions
Using paper, paper clips, an index card, and tape, teams of learners design flying devices to (1) stay in the air as long as possible and (2) land as close as possible to a given target.

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.
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.

Turning the Tables
Source Institutions
In this activity, learners explore geometry and spatial relationships as they figure out how to arrange tables for a party.

Tactile Mazes
Source Institutions
In this activity (15th activity on the page) about the sense of touch, learners use glue and cardboard to construct a maze they use with their eyes closed.

Paper Bridges
Source Institutions
In this activity, learners build bridges using paper and explore how much weight each bridge design can support.

Stairway to the Sky
Source Institutions
In this math activity, learners use cubes to calculate how many blocks it would take to build stairways with different heights.

The Gator Pie Game
Source Institutions
In this activity, learners explore fractions as they help gators share pies.
Frustrations with Fractions
Source Institutions
In this math activity, learners make a set of fraction cards to play a game that will help relieve their fraction frustrations.

Old Faithful Plumbing Investigation
Source Institutions
This activity (located on page 3 of the PDF) is a full inquiry investigation into mapping the underground “plumbing” of geysers.

Paper Airplane Contest
Source Institutions
In this fun physics activity (page 9 of the pdf), learners take part in a paper airplane design challenge.

Paper Bridge
Source Institutions
In this engineering activity, challenge learners to construct a paper bridge that can support 100 pennies.

Motor Effect
Source Institutions
See what force a magnet has on a wire that has current running through it: will it push it, pull it, or will nothing happen? This is the foundation of a simple electric motor.

Cooling the Mummy's Tomb
Source Institutions
In this activity, learners conduct an experiment to help Pharaoh design a better insulated tomb.
Six Squares: Geometry and Design
Source Institutions
In this activity, learners take a turn contributing a closed figure made of six squares to a large grid; each must be different from all the others on the grid so far.

Straws and Airplanes
Source Institutions
Create airplanes from straws and geometric shapes. Test them out to see how far they can fly, or how accurately they can be aimed.

By the Numbers
Source Institutions
Learners describe objects in a room using only numbers and shapes. They can measure the object (like a desk) and make a list of facts about it (e.g.

How Much is a Name Worth?
Source Institutions
In this math lesson, learners use simple addition facts to compute values (in dollars and cents) for their names.

Under Pressure
Source Institutions
In this simple activity, learners discover how a mere piece of paper can be used to hold up the weight of a heavy book.
