Digger
Source Institutions
In this activity, learners build their own construction cranes using tongue depressors and pushpins.
Cartesian Diver
Source Institutions
In this quick activity (page 1 of the PDF under SciGirls Activity: California Fish), learners will build a simple Cartesian Diver in an empty 2-liter bottle.
Pop Can "Hero Engine"
Source Institutions
In this activity, learners build water-propelled engines from soft drink cans.
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.
Build A Hydrometer
Source Institutions
In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.
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.
Exploring Forces: Static Electricity
Source Institutions
In this activity, learners investigate what happens when you build up static electricity on plastic balls.
Water Motor
Source Institutions
In this physics activity (page 10 of the PDF), learners will explore how energy from moving water can be used.
Exploring the Universe: Star Formation
Source Institutions
In this activity, participants will learn how stars form from the dust and gas that exists in space clumping together.
We Have Capture!
Source Institutions
Using simple materials, learners will construct the end effector (grasping device) of a robotic arm and use the device to capture and pick up an object.
Milk Carton Boats
Source Institutions
This activity (on page 2 of the PDF SciGirls Activity: Milk Carton Boat) is a full inquiry investigation into boat hull design.
Design and Build a Wind Vane
Source Institutions
In this activity, learners design and build a simple wind vane —one of the oldest kinds of weather tools— and use it to show wind direction.
Airfoils
Source Institutions
In this experiment, learners discover how an airfoil creates lift. Learners use simple materials to build an airfoil and test it at different angles to investigate Bernoulli's principle.
Clipper Creations
Source Institutions
In this activity, learners create a working model of a nail clipper. This activity helps learners learn the basic principles of simple machines, engineering design and model building.
Target Practice
Source Institutions
In this dynamic activity, learners build a catapult that launches projectiles, such as marshmallows.
Make Your Own Mini Mini Golf Course
Source Institutions
Build your own Mini Mini Golf Course and learn about hands-on building and design, basic circuitry, motion modules and more!
Balloon Rockets
Source Institutions
In this activity, learners will create a model rocket out of an inflated balloon attached to a straw on a taught string.
Crazy About Kites
Source Institutions
In this activity, learners build a kite out of paper, change it, and try to make it fly even better. With their new knowledge of kite making, students can then go on to create their own kite designs.
Exploring Black Holes and Gravity
Source Institutions
This fun and simple hands-on astronomy activity lets learners imagine what would happen if our Sun were replaced with a black hole.
