Glitter Bottles
Source Institutions
In this activity, learners will create glitter bottles with adult supervision. These are a fun way for little ones to practice observing and making comparisons.
COSI Quicksand
Source Institutions
In this chemistry experiment, learners get to make a very bizarre substance using corn starch and water. Is it a solid? Is it a liquid? Or is it a different kind of substance entirely?
School of Fish
Source Institutions
In this activity, learners will make fish cutouts that propel through the water with the help of surface tension.
Rock Candy
Source Institutions
In this yummy chemistry activity which requires adult supervision, learners use sugar and water to explore how crystals form.
Magnetism Hunt
Source Institutions
In this activity about magnetism (page 4 of the PDF), learners will experiment with magnets and different objects to find out that not all metals are attracted to magnets.
Float Your Boat
Source Institutions
In this physics activity, learners will explore buoyancy.
COSI's Bubble Recipe
Source Institutions
Everybody loves bubbles, and this is the best bubble recipe ever!
Magnetisphere
Source Institutions
In this activity about magnetism (page seven of the pdf), learners experiment with magnets to better understand how magnetic fields work.
The Pressure's On
Source Institutions
In this chemistry activity, learners explore chemical reactions and their effects, including the kind of reaction in the human body that makes people burp!
Bent Toward Science: Refraction
Source Institutions
This is an activity about the behavior of light. Using simple, everyday objects, learners will discover that light moves in straight lines until acted upon by another object.
Buoyant Bubbles
Source Institutions
What keeps bubbles and other things, like airplanes, floating or flying in the air?
Rollin’ Rollin' Rollin'
Source Institutions
In this physics activity (page 12 of the PDF), learners explore potential and kinetic energy by rolling different sized marbles down an inclined plane.
Inertia
Source Institutions
In this physics activity (page 8 of the PDF), learners will explore the concept of inertia by attempting to run and stop quickly.
Push It Out
Source Institutions
In this physics related activity which requires adult supervision, learners make their own powerful water rocket and, with it, explore Newton's Third Law of Motion.
Weight For It!
Source Institutions
In this activity about weights and balances, learners create their own balance using paper cups. Then, learners explore how to compare the relative mass of objects.
Hang Time
Source Institutions
In this physics activity, learners will build their own parachutes out of tissue paper. They will explore the effects of weight, height, and design on the parachutes' speed and stability.
Eggshell Inertia
Source Institutions
In this physics activity (page 14 of the PDF), learners gain a better understanding of how friction and mass affect objects by comparing the rotational inertia of raw and hard-boiled eggs.
Chromatography
Source Institutions
In this activity (page 3 of the PDF), learners will observe a physical change.
Mighty Seeds
Source Institutions
In this biology experiment, learners plant soybean seeds in plaster of Paris, witnessing firsthand the mighty power and ability of plants to grow in adverse conditions.
Edible Ink
Source Institutions
In this chemistry activity (page 6 of the PDF), learners observe a chemical change. Learners write and reveal a secret message using edible ink.
