Crushing Test
Source Institutions
In this activity, learners design a crushing test and discover that identifying and controlling the variables may be difficult.
Red, White and Blue II Demonstration
Source Institutions
In this chemistry demonstration, learners investigate the rule "likes dissolve likes" by combining three, immiscible liquids to create a colorful density column.
Invisible Ink
Source Institutions
In this simple chemistry activity (page 1 of PDF under SciGirls Activity: Colorblind Dogs) about acids and bases, learners will mix a baking soda and water solution and use it to paint a message on a
M&M's in Different Sugar Solutions
Source Institutions
In this activity, learners investigate whether having sugar already dissolved in water affects the speed of dissolving and the movement of sugar and color through the water.
Onion DNA Extraction
Source Institutions
This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells using simple materials.
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.
Disappearing Colors
Source Institutions
In this challenge, learners figure out how to make a juice stain disappear.
Air-filled (Pneumatic) Bone Experiments
Source Institutions
Just like birds, some dinosaurs had air-filled (pneumatic) bones, which made the dinosaurs' skeletons lighter.
Using Chemical Change to Identify an Unknown
Source Institutions
In this activity, learners will develop a method to test five similar-looking powders (baking soda, baking powder, cream of tartar, detergent, and cornstarch) with four test liquids (water, vinegar, i
Dye Like A Natural
Source Institutions
In this activity, learners stain fabrics--on purpose!
Growing Rock Candy
Source Institutions
In this activity, learners make their own rock candy. Crystals will grow from a piece of string hanging in a cup of sugar water. The edible crystals may take up to a week to form.
Electricity: Fruit Batteries
Source Institutions
In this activity, learners create a battery from fruit. This activity helps learners explore electricity, electrochemistry, and series circuits as well as the process of scientific inquiry.
Density Rainbow
Source Institutions
In this activity, learners mix several sugar solutions to investigate the property of density. Each sugar solution has a different density and color of the rainbow.
pHun with Cabbage
Source Institutions
In this chemistry activity, learners will test the pH of various foods and household substances using cabbage.
Cheese: Behold the Power of Chemistry
Source Institutions
In this activity on page 7 of the PDF (Get Cooking With Chemistry), learners conduct an experiment to get an idea of how cheese is made.
Powder Particulars
Source Institutions
In this introductory activity and demonstration, learners are introduced to the concept that different substances react chemically in characteristic ways.
Laser Jello
Source Institutions
In this activity, learners use gelatin as a lens to investigate the properties of laser light.
Yeast DNA Extraction
Source Institutions
This laboratory exercise is designed to show learners how DNA can easily be extracted from yeast using simple materials.
Hot Stuff!
Source Institutions
In this activity, learners discover that sand is the major ingredient in glass.
Sweet Speedway
Source Institutions
In this activity, learners test different food items by timing how long it takes each liquid to slide from the top of a ramp to the bottom.
