Skin Deep
Source Institutions
In this activity, learners explore how to protect their skin while applying pesticides to plants.
Hot and Cold
Source Institutions
In this chemistry challenge, learners discover that many chemical reactions involve heat loss or gain.
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.
Membrane Permeability with Beets
Source Institutions
In this lab exercise, learners explore diffusion, cell membranes and particle size using beets and three alcohols.
Shocking Fruit
Source Institutions
In this activity, learners discover how a piece of fruit can act as an electrolyte, conducting electricity between two different metals.
Weather Stations: Temperature and Pressure
Source Institutions
In this activity, learners discover the relationship between temperature and pressure in the lower atmospheres of Jupiter and Earth.
Water Underground
Source Institutions
Many people get water from a source deep underground, called groundwater.
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?
Acids & Bases
Source Institutions
In this activity, learners test the pH of safe liquids available at home by creating a pH indicator from mashed blueberries.
Mixing and Unmixing in the Kitchen
Source Institutions
In this chemistry investigation, learners combine common cooking substances (flour, baking powder, sugar, salt, pepper, oil, water, food coloring) to explore mixtures.
The Decayed Pumpkin
Source Institutions
In this "Sid the Science Kid" activity from Episode 106: My Mushy Banana, learners explore the effects of decay by comparing and contrasting something (an old pumpkin) that's decayed with the same thi
Sweat Spot
Source Institutions
In this activity, learners use a chemical reaction to visualize where moisture forms on the body.
Finding Red
Source Institutions
In this chemistry challenge, learners systematically investigate which combination of four solutions produces a deep red color.
Invisible Sunblock
Source Institutions
This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.
A Feast for Yeast
Source Institutions
In this activity on page 6 of the PDF (Get Cooking With Chemistry), learners investigate yeast. Learners prepare an experiment to observe what yeast cells like to eat.
Glow in the Dark
Source Institutions
Learners experiment to see which colors of light will cause a phosphorescent (glow-in-the-dark) material to glow.
Light and Dark
Source Institutions
Learners examine the properties of light by experimenting with an LED-flashlight and polarizing filters. When two polarizers are used, they block all light when they are placed at right angles.
Chemical Identification
Source Institutions
In this activity, learners discover how a cabbage juice indicator helps identify acids and bases, and how iodine indicates the presence of starch.
Dip Dip, Hooray
Source Institutions
Lakes, streams and other freshwater bodies are a habitat for lots of living things, big and small.
Magic Colored Milk
Source Institutions
In this chemistry activity (page 5 of the PDF), learners will use milk and a few other basic ingredients to create a chemical change to make a color wheel.
