Burning Issues
Source Institutions
Learners use a candle to investigate the products of combustion. When a glass rod is held over a lit candle, the candle flame deposits carbon on the rod.
What is a “Convection Cell”?
Source Institutions
In this demonstration, learners can observe a number of small convection cells generated from a mixture of aluminum powder and silicon oil on a hot plate.
Balloon in a Flask
Source Institutions
Learners observe a flask with a balloon attached over the mouth and inverted inside the flask.
Balloon Inside a Bottle
Source Institutions
In this activity about phase change and condensation, learners boil water in an empty pop bottle in the microwave.
Liesegang Rings
Source Institutions
This display shows slow chemical reactions in colorful crystal formations known as Liesegang Rings. These reactions are similar to those forming the rings in agates.
Release the Rainbow
Source Institutions
In this activity, learners create a water prism to break light into the seven colors of the rainbow.
Solar Energy
Source Institutions
In this activity (page 11 of PDF), learners compare the air pressure within a dark and a light bottle both heated by the sun, and discover that solar energy can be collected and stored in many ways
Wheat Evolution: Dough Washing
Source Institutions
In this activity (Page 22 of PDF), learners investigate the evolution of wheat by washing different types of dough with water and comparing the results.
Updrafts in Action
Source Institutions
In this weather activity/demonstration, learners watch as a ping pong ball is suspended in a stream of air supplied by a hair dryer.
The Ballistic Pendulum
Source Institutions
In this physics crime lab or demonstration, learners pretend they are criminologists and must find the "muzzle velocity" (speed of the bullet as it leaves the gun) of a gun used to commit a crime.
Wheat Evolution: Dough Rising and Baking
Source Institutions
In this activity (Page 25 of PDF), learners investigate the evolution of wheat by creating dough from different flours, observing the samples of dough as they rise, and then baking the dough.
How Do Things Fall?
Learners engage in close observation of falling objects. They determine it is the amount of air resistance, not the weight of an object, which determines how quickly an object falls.
What's Your Blood Type?
Source Institutions
In this activity, learners perform a simulated blood test procedure.
Cake by Conduction
Source Institutions
In this demonstration, cook a cake using the heat produced when the cake batter conducts an electric current.
Rainbow in the Room
Source Institutions
This activity generates learner excitement about light through the creation of a room-sized rainbow.
Origami Flying Disk
Source Institutions
In this three-part activity, learners use paper to explore Bernoulli's Principle — fast-moving air has lower pressure than non-moving air.
Properties of Metals
Source Institutions
In this activity, learners explore the properties of metals at four stations. The stations include A) Magnetism and Breakfast Cereal; B) Conductivity of Metals; C) Alloys; and D) Metal Plating.
Stretch the Chain and See the Light
Source Institutions
In this activity, learners use their strength to light a light bulb. A chain made from paper clips is placed in series with a battery and flashlight bulb.
That Sinking Feeling
Source Institutions
In this quick activity, learners observe how salinity and temperature affect the density of water, to better understand the Great Ocean Conveyor.
Potato Straw
Source Institutions
In this physics demonstration, learners are challenged to insert a straw the furthest into a potato.
