Home Molecular Genetics
Source Institutions
In this activity, learners extract DNA from their own cheek cells, then create a rudimentary DNA profile similar to those seen on crime scene dramas.

Give and Take
Source Institutions
In this activity, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes.

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!

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.

Hot Stuff!: Investigation #2
Learners test two jars containing hot water, one covered with plastic and one open, for changes in temperature.

Sink or Swim?
Source Institutions
In this activity, learners identify different plastics in a mystery bag. Learners discover that plastics are classified #1 through #7.

Read Without Seeing
Source Institutions
Learners write a message in Braille using beans to form the patterns of dots. Learners glue beans in place, and then challenge another learner to read the message.

There's Always Room For JELL-O
Source Institutions
In this activity, learners cut wells in JELL-O© and load the wells with different detergent solutions.

Gecko Feet
Source Institutions

Head, Shoulder, Knees and Toes...and Hands, Fingers and Back
Source Institutions
Are fingers the only place on the body where we use our sense of touch? In this activity (6th activity on the page), learners test the touch sensitivity of different parts of the body.

Self-Assembling Dessert Toppings
Source Institutions
This is an activity (located on page 3 of the PDF under Self-Assembly Activity) about self-assembly, the ability of molecules to assemble themselves according to certain rules.

Glitter Slime
Source Institutions
In this activity on page 8 of the PDF, learners make a slimy substance very similar to mucus, and sprinkle it with glitter to imitate the way that allergens are trapped.

Building a Magic Carpet
Source Institutions
In this activity (page 89 of the PDF), learners compare and contrast pitch and roll motions by using a Magic Carpet maze similar to one that was used for Neurolab investigations about microgravity.

Sea Turtle First Aid Investigation
Source Institutions
This activity (located on page 4 of the PDF under GPS: Sea Turtles Activity) is a full inquiry investigation into testing a repair material.

Can Nutrients in Water Cause Harm?
Source Institutions
In this water pollution activity, learners create pond water cultures and investigate the effects of adding chemicals or natural nutrients.

Racing with the Sun: Creating a Solar Car
Source Institutions
Learners use engineering design principles to construct and test a fully solar-powered car. Solar car kits usually include a photovoltaic cell and motor; some include a chassis as well.

Hot Stuff!: Creating and Testing for Carbon Dioxide
In this demonstration, learners observe vinegar and baking soda reacting to form carbon dioxide (CO2) gas.

How to Make an Audio Tape Bow
Source Institutions
From this How To slide show, you create an Audio Tape Bow that can play distorted audio sounds by running it across a tape head.

The Self-Watering Terrarium
Source Institutions
In this biology/ecology activity, learners construct a terrarium out of a tennis ball container. This terrarium is unique because it never has to be watered.

Home Water Audit
