Zipline
Source Institutions
In this design activity, learners create a vehicle that can transport a load, like a favorite toy or as a recycled object, from the top of a zipline to the bottom using only gravity.
Airboat
Source Institutions
In this activity related to Newton's Laws of Motion, learners build a boat powered by a propeller in the air.
Ramps 2: Ramp Builder
Source Institutions
In this inquiry-based learning activity, learners design, build, and test their own ramps. They are introduced to a variety of materials and explore putting them together.
Digger
Source Institutions
In this activity, learners build their own construction cranes using tongue depressors and pushpins.
Engineering Ups and Downs
Source Institutions
In this activity, learners explore the engineering and principles behind working elevators.
Let's Make Music
Source Institutions
In this activity, learners will create their own percussion instrument with recycled materials. Learners will explore design, fabrication, cause and effect and sound through this activity.
Roller Coasters
Source Institutions
In this design challenge, learners will create their own roller coaster using household objects for the track and a marble or small ball as their cart.
Sail Car Design
Source Institutions
This activity (on page 3 of the PDF under GPS: Sailboat Design Activity) is a full inquiry investigation into design optimization.
Invent on the Spot
Source Institutions
In this activity, learners design a device to solve a problem: how to get a ball out of a drain pipe.
Levers at Play
Source Institutions
In this activity, learners consider how a simple machine, a lever, turns a small push or pull (a small force) into a larger--or stronger--push or pull (a larger force).
Lift Off!
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Lift Off) is a full inquiry investigation into the engineering challenges of sending scientific sensors into space.
Cardboard Automata
Source Institutions
Cardboard Automata are a playful way to explore simple machine elements while creating a mechanical sculpture.
Hydraulic Car
Source Institutions
In this activity, learners build cars using syringes and water-powered hydraulics. Learners construct the car frame out of cardboard and set up a hydraulic system to raise and lower the car.
Propeller-Powered Car
Source Institutions
In this activity, learners construct cars that are powered by hand-made, electric propellers.
Cable Car
Source Institutions
In this activity, learners string a line across the room and build cable cars that can move from on end to the other.
Hovercraft
Source Institutions
In this activity, learners build a hovercraft using a paper plate, cup, and simple motor.
Globby Gooey Gak
Source Institutions
In this activity, learners concoct some stretchy green goo called Gak. This activity will introduce learners to polymers, chemical reactions, and how scientists invent new materials.
Target Practice
Source Institutions
In this dynamic activity, learners build a catapult that launches projectiles, such as marshmallows.
Interactive Gumball Machine
Source Institutions
In this activity, learners review the history of gumball machines and explore potential and kinetic energy, while working in teams to build a gumball slide.
Parachuting Pinwheel
Source Institutions
Build a pinwheel that works without wind! This activity contains steps on how to build a parachuting pinwheel out of paper, a film canister, and some brads.
