See the Light
Source Institutions
Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.
To Dye For
Source Institutions
Learners add two dyes to mineral oil and water, and then compare their miscibility (how well they mix) in each.
Acid Rain
Source Institutions
In this chemistry demonstration, acid rain is simulated in a petri dish.
Memory Match
Source Institutions
In this classic memory game (on pages 37-45 of PDF), learners turn over tiles to reveal images on the back.
Wingin' It
Source Institutions
Learners explore the Bernoulli effect by building an airfoil (airplane wing) and making it fly.
History of Electricity
Source Institutions
This is a series of demonstrations about different electrical and magnetic phenomena.
Pollution Diffusion
Source Institutions
Learners design their own experiment to investigate how pollution diffuses through ground material.
Tricky Tangrams
Source Institutions
In this activity (on pages 49-54 of PDF), learners play with tangrams, a set of triangles, squares and a parallelogram that can combine into a larger square as well as all sorts of other shapes.
Rock Bottoms
Source Institutions
Learners add acid rain (nitric acid) to two cups that represent lakes. One cup contains limestone gravel and the other contains granite gravel.
Lost Labels
Source Institutions
In this experiment, learners will conduct chemical and physical tests to identify mystery substances.
Inner Space
Source Institutions
In this activity, learners discover that there is space between molecules even in a cup "full" of water. They first fill a cup with marbles, and then add sand to fill the gaps between the marbles.
Designing Bandages
Source Institutions
Learners design different shaped bandages for different purposes. First, they draw their designs on paper.
Plastic Milk: You can make plastic from milk
Source Institutions
In this activity (on page 2 of the PDF), learners make a plastic protein polymer from milk. Adding vinegar to milk causes the protein casein to solidify or curdle.
Draggin' Boats
Source Institutions
Learners design, build, and test models of "dragon boats" made from up to three milk cartons.
Big Things Come in Little Packages
Source Institutions
As a group, learners investigate three packages which are all the same size and shape, but have different contents. One is filled with foam, one is filled with wood, and one is filled with metal.
Layers of Liquids
Source Institutions
Learners pour equal amounts of coffee, mineral oil, corn syrup, and alcohol into a beaker. The liquids resolve into stacked layers, and learners can infer which liquids are the most and least dense.
Oh Buoy!
Source Institutions
Learners work in pairs to design, construct, and test a device that exhibits positive, neutral, and negative buoyancy. They test a number of different objects in water to see if they sink or float.
Sketch a Skeleton
Source Institutions
In this activity (on pages 15-18 of PDF), learners make a life-size two-dimensional paper model of their own skeletons.
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.
Curious Contraptions
Source Institutions
In this engineering design activity, learners will design, test, and build a “haunting machine” to solve a Sherlockian mystery.
