Learners turn over a random selection of cards from a larger set. From the words revealed, they try to determine the sentence represented on the larger set of cards.

Learners investigate a pre-constructed mystery tube to determine its interior mechanism.

In this activity, learners make a photographic image—without a camera!

In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.

In this tabletop board game, players will represent a team of scientists and engineers sending a spacecraft on a mission to space.

In this activity, learners analyze a fictionalized report of life on Mars, based on a real NASA satellite photo, and explore how to separate scientific fact from fiction.

During this lesson, learners will determine their blood pressure and learn about systolic and diastolic pressures.

Learners listen to and try to decipher a radio message that was sent from Earth to possible intelligent civilizations.

Directed by instructional cards, learners kinesthetically model cell communication by acting as components in a cell signaling pathway.

Using simple materials from around the house and recycled materials, learners will engineer a grabber device to pick up and put down objects that are at least 12 inches away.

In this activity, learners build a speedboat using paint paddles, a propeller, and film canister. Learners attach a simple circuit and motor to the boat to power the propellers.

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

In this activity, learners create night lights using a plastic cup, programmable PICO Cricket, tri-color LED, and sensor.

In this activity, learners create painting machines that can paint moving forwards and backwards.

In this genetics activity, learners discover how to extract DNA from green split peas.

This activity shows learners how computers use numbers to represent pictures. A grid is used to represent the pixels (short for picture elements) of a computer screen.

This is a game that is sure to sharpen players' basic math skills. Players must use four randomly selected numbers to create an equation that equals a fifth number.

Based of the The Tech Challenge 2015, learners will engage in two mini-design challenges related to seismic engineering.

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

In this activity, learners are challenged to create a parachute using easily sourced materials in order to transport a LEGO figure safely to the ground.
