Latent Prints
Source Institutions
In this activity, learners examine fingerprints. Learners leave a hidden print on a surface and then make their own print detecting powder from graphite (found in pencils).
Which Powder is It?
Source Institutions
In this chemistry challenge, learners identify an unknown white powder by comparing it with common household powders.
Odors Aloft
Source Institutions
Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.
The Liquid Rainbow
Source Institutions
Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.
Rice Handle
Source Institutions
In this physics activity, learners attempt to lift a jar full of rice using only a spoon.
Cool Hot Rod
Source Institutions
If you have access to a copper metal tube, this activity does a great job demonstrating what happens to matter when it's heated or cooled. This activity requires some lab equipment.
Checking For Starch
Source Institutions
In this chemistry activity (page 3 of the PDF), learners will observe a chemical change, specifically what happens to iodine when it is applied to ripe and unripe apples.
DNA Extraction
Source Institutions
Learners use a simple process to extract DNA from strawberries.
What's In Your Breath?
Source Institutions
In this activity, learners test to see if carbon dioxide is present in the air we breathe in and out by using a detector made from red cabbage.
What's So Special about Water: Absorption
Source Institutions
In this activity about water's cohesive and adhesive properties and why water molecules are attracted to each other, learners test if objects repel or absorb water.
Testing Falling Peanut Butter Sandwich Myth
Source Institutions
In this activity related to rotational inertia (page 1 of the PDF under SciGirls Activity: Microgravity), learners will use a bit of scientific experimenting to test if open-faced peanut butter sandwi
Crystal Gardens
Source Institutions
In this activity, which requires adult supervision, learners get to explore the awesome power of chemistry.
Strong Bones, Weak Bones
Source Institutions
Most people will break a bone in their body at some point in their life, but how much force does it take to break one?
DNA Extraction from Wheat Germ
Source Institutions
DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique. This activity allows you to see long, stringy strands of DNA extracted from wheat germ.
Rippin' Rockets
Source Institutions
In this activity, learners work in pairs to conduct a series of experiments using a balloon, drinking straw, and paper.
DNA Extraction from Cheek Cells
Source Institutions
DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique.
What does Color have to do with Cooling?
Source Institutions
In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.
In Proportion
Source Institutions
Through this nutrition activity (page 5 of the PDF), learners will understand—and probably be surprised by—how big serving sizes of various foods should be.
Inner Space
Source Institutions
In this activity, learners discover that there is space between molecules even in a cup "full" of water. They first fill a cup with marbles, and then add sand to fill the gaps between the marbles.
DNA Spooling: Isolate DNA from Onion Cells
Source Institutions
In this experiment, learners isolate Deoxyribonucleic Acid (DNA) from onion cells using a simple extraction procedure.
