Fan Cart
Source Institutions
If a sailboat is stranded because there is no wind, is it possible to set up a fan on deck and blow wind into the sail to make the boat move?
Laser Lissajous: PVC Version
Source Institutions
In this activity, learners use a laser pointer and two small rotating mirrors to create a variety of fascinating patterns, which can be easily and dramatically projected on a wall or screen.
Stereoscope
Source Institutions
In this activity, learners construct a device that allows them to view 2-D images in 3-D.
Capturing Homemade Microgravity
Source Institutions
This activity (page 2 of the PDF under SciGirls Activity: Microgravity) is a full inquiry investigation into how ordinary things behave in microgravity, similar to what astronauts experience.
Forensic Science: Hair Sample Investigation
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Forensics) is a full inquiry investigation into how hairs from a crime scene are matched to suspects.
Laser Lissajous: Binder Clip Version
Source Institutions
In this activity, learners use a laser pointer and two small rotating mirrors to create a variety of fascinating patterns, which can be easily and dramatically projected on a wall or screen.
Disease Detectives
Source Institutions
In this activity, learners examine antibodies and antibody recognition using a model.
Robot Basketball
Source Institutions
In this activity, learners explore accuracy and precision.
Nano Latch-n-Catch
Source Institutions
In this activity, learners design a therapeutic agent to image and/or cure various diseases in the respiratory system.
Jet Propulsion
Source Institutions
In this two-part activity, learners work in pairs to examine the four basic stages of a turbine engine.
Oil Spill Solutions
Source Institutions
In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.
Hockey Stick Power!
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Hockey) is a full inquiry investigation into how a hockey stick’s flex affects shooting power and accuracy.
Floodplain Modeling
In this design-based lesson, learners study flood dynamics as they modify a riverbed with blockages or levees to simulate real-world scenarios.
Particle Detection
Source Institutions
By tossing, collecting, and sorting beanbags, learners understand how the IBEX spacecraft uses its sensors to detect and map the locations of particle types in the interstellar boundary.
Make a Comet Model and Eat It!
Source Institutions
In this activity, learners build models of comets, using edible materials, to learn about comets' structure.
Wind Turbine Blade Design
Source Institutions
In this activity, learners design, build and test wind turbines. Learners go through the design process and use the scientific method to test important blade variables.
Low-Tech Water Filter for High-Impact Clean
Source Institutions
In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.
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).
Moving and Working in Space
Source Institutions
In this activity, groups of four learners must complete a set of four manual tasks. The restrictions are that they must complete the tasks in a limited time while wearing garden or rubber gloves.
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.
