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.
3D-tection: Trying to Fit In
Source Institutions
In this activity, learners explore how molecules must fit together, like a lock and key, in order to identify each other and initiate a new function as a combined unit.
Balloon Car
Source Institutions
In this activity, learners explore force and motion by constructing cardboard cars that are propelled by balloons.
Slide Whistle
Source Institutions
In this activity, learners build a slide whistle using PVC pipe, bamboo skewer, and piece of foam. Construction of the instrument is relatively simple.
Finger Basketball
Source Institutions
In this activity, learners build mini-basketball courts using cardboard and measuring spoons. Use this activity to introduce learners to catapults, forces, and levers.
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.
Exploring Tools: Mitten Challenge
Source Institutions
In this activity, learners build a LEGO® structure while wearing mittens. This activity shows learners how difficult it is to build small things when your tools are too big.
Torsion Drum
Source Institutions
In this activity, learners build a musical drum using a cardboard tube, plastic wrap, and beads.
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.
Bouncing Yo-Yo
Source Institutions
In this activity, learners build unique yo-yos, which spin round and round without moving up and down.
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.
Magnet Tower
Source Institutions
In this activity, learners build magnetic towers to explore the forces and properties of magnets.
Squidgy Slime
Source Institutions
In this chemistry activity, learners transform two ingredients (4% polyvinyl alcohol solution and 4% borax solution) into gooey slime.
Rubber Band Boat
Source Institutions
In this activity, learners build styrofoam boats powered by twisted rubber bands.
Puff Car
Source Institutions
In this activity, learners are challenged to design a wind-powered car using only a handful of household materials.
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.
Kick Stick Challenge
Source Institutions
In this design challenge activity, learners investigate series circuits and motors to build a hand-held "kick stick." Their goal is create a battery-operated device that sends a Ping-Pong ball across
