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.
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.
Fireworks!
Source Institutions
In this chemistry lab activity, learners model the colors of fireworks by burning metallic solutions in a flame and observing the different colors produced.
Giant Chromosomes: Fruit Fly DNA and You
Source Institutions
Many of the genetic sequences found in the fruit fly genome are similar to those found in humans.
Rocket Reactions
Source Institutions
The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.
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.
Choose Your Ooze
Source Institutions
During this activity, learners will make different versions of "ooze" using varied proportions of detergent and glue.
Lost Labels
Source Institutions
In this experiment, learners will conduct chemical and physical tests to identify mystery substances.
It's a Gas!
Source Institutions
In this activity, learners explore two properties of gases: gases take up space and exert pressure. Learners assemble two flasks and a beaker, connecting them with stoppers and tubing.
Fruit Juice Mystery
Source Institutions
In this chemistry challenge, learners work to figure out which of four juices are real, and which is just food coloring and sugar.
Fizzy Fun
Source Institutions
In this activity, learners test what happens when they put baking power on different frozen liquids.
Green Pennies
Source Institutions
In this activity, learners create their own experiment and test which of 4 mixtures of household chemicals turn pennies green over 5 days.
Reaction: Yes or No?
Source Institutions
In this activity, learners mix ingredients in a plastic bag, and then identify three characteristics of a chemical reaction: production of heat, color change, and production of a gas.
Forwards and Backwards
Source Institutions
In this activity, learners explore acids and bases by preparing six solutions that combine vinegar and ammonia, ranging from acid (all vinegar) to base (all ammonia).
