Smooth Operator
Source Institutions
In this activity, learners explore surgical instrument design. Teams of learners construct surgical instruments from everyday materials.
Stack 'Em Up
Source Institutions
In this simple and fun activity, learners build a tower of cups to explore distribution of weight. Learners make predictions about their towers and test their designs.
Sticky Structures
Source Institutions
In this engineering/design/arts and crafts activity, learners design and build "platforms" or "bridges" that can hold weight, and test which glue makes the strongest structure.
DNA Extraction: Look at your genes!
Source Institutions
Extract your DNA from your very own cells! First, learners swish salt water in their mouth to collect cheek cells and spit the water into a glass.
Solar Energy
Source Institutions
In this activity (page 11 of PDF), learners compare the air pressure within a dark and a light bottle both heated by the sun, and discover that solar energy can be collected and stored in many ways
A Simple Escapement Mechanism
Source Institutions
In this activity, learners build a simple mechanism that regulates the "escape" of energy released by a falling weight by portioning it into discrete amounts.
No bones about it!
Source Institutions
This is an activity (located on page 3 of the PDF) about the mixture of materials in bone and how they affect its strength.
Air Cannon
Source Institutions
In this activity (page 1 of PDF under SciGirls Activity: Forecasting), learners will construct an air cannon by cutting a hole in the bottom of a bucket and stretching a garbage bag over the other end
Solar Water Heater
Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.
Guiding Light
Source Institutions
In this optics activity, learners use glass and water to demonstrate total internal reflection (TIR).
House Warming
Source Institutions
In this physical sciences activity, learners explore how passive solar design increases energy efficiency.
Nano Scavenger Hunt
Source Institutions
This is an activity (located on page 3 of PDF under Where's Nano? Activity) about identifying nanoscale objects and phenomena in today's world.
Working with Watermills
Source Institutions
In this activity, learners explore how watermills have helped harness energy from water through the ages.
Sound Mixer: A Multi-track Mixer of Animal Sounds
Source Institutions
This is a virtual representation of a sound mixer containing pre-looped sounds of animal, insect, and environmental noises.
Making Recycled Paper
Source Institutions
In this activity on page 11 of the PDF, learners follow simple steps to recycle old newspaper into new paper.
Urine the Know
Source Institutions
In this activity on page 5 of the PDF, learners compare water with artificial urine to see how urinalysis works. Learners use urinalysis test strips to test for glucose and protein in the fake urine.
Fun with Speedboats
Source Institutions
In this activity, learners explore how boats are engineered to achieve speed.
Stethoscope
Source Institutions
Make a copy of the first stethoscope with only a cardboard tube! René Laennec invented the first stethoscope in 1819 using an actual paper tube!
Submarine: Lift Bag Lander
Source Institutions
In this activity (on page 4), learners create a submarine using a plastic sandwich bag. This is a fun way to learn about buoyancy and how captured gas can cause objects to float.
Bring it into Focus
Source Institutions
In this activity (page 2 of PDF), learners play with a lens and a piece of paper to focus an image on the paper. Learners look at different things, and see how the lenses affect the image.
