Hot Stuff!: Investigation #4
Learners test two jars containing soil, one covered and one open, for changes in temperature. After placing the jars in the Sun, learners discover that the covered jar cools down more slowly.
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).
Hot Stuff!: Investigation #1
Learners test two jars, one containing plain air and one containing carbon dioxide gas, to see their reactions to temperature changes.
Skin Deep
Source Institutions
In this activity, learners explore how to protect their skin while applying pesticides to plants.
Find the Fat
Source Institutions
Fat is a very important component in our diet. It's the most efficient source of energy in our bodies, and plays an important role in the flavor of foods.
Wheat Evolution: Sedimentation Testing
Source Institutions
In this activity (Page 30 of PDF), learners investigate the evolution of wheat by conducting sedimentation tests on different flours.
The Pulse of Gravity
Source Institutions
In this astronomy activity (page 3 of the PDF), learners will examine the effects of gravity on a person’s pulse and explore how gravity can differ from planet to planet.
Shark Sense of Smell
Source Institutions
This is an activity about our sense of smell and how it compares to sharks' super noses. Learners will create varying solutions of water and perfume.
Chew that Gum
Source Institutions
In this quick activity (page 1 of PDF under SciGirls Activity: Exercise and Memory), learners will investigate what happens to bubble gum when it is chewed for 5-10 minutes.
Plant Power
Source Institutions
In this chemistry challenge, learners identify which plants have the enzyme "catalase" that breaks hydrogen peroxide into water and oxygen.
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.
Oh Boy Buoyancy
Source Institutions
In this physics activity, learners will explore the concept of buoyancy, especially as it relates to density.
The Space Place
Source Institutions
In this activity (23rd on the page), learners conduct an experiment to examine memory and learning.
Gummy Shapes
Source Institutions
In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.
Screaming Balloon
Source Institutions
In this quick activity (page 1 of the PDF under SciGirls Activity: Extreme Sounds) about sound vibrations, learners will investigate which small objects, such as coins, hex nuts, or marbles, produce t
Vibrant Cords
Source Institutions
In this activity, learners will explore how the voice works and feel the vibrations produced by vocal cords.
Cover Your Mouth
Source Institutions
In this health activity (page 3 of the PDF), learners will discover why covering their mouth and nose while sneezing is so important.
Membrane Permeability with Beets
Source Institutions
In this lab exercise, learners explore diffusion, cell membranes and particle size using beets and three alcohols.
Mix and Match
Source Institutions
In this optics activity, learners explore color by examining color dots through colored water and the light of a flashlight.
Thumbs Away!
Source Institutions
Learners discover how important their thumbs are by attempting various tasks without them. After tying up their thumbs, learners attempt to legibly write their names or play catch with a tennis ball.
