This is written as a static display, but can easily be adapted to a hands-on experiment for learners to conduct.

In this activity, learners examine fingerprints. Learners leave a hidden print on a surface and then make their own print detecting powder from graphite (found in pencils).

Learners are given mysterious white powders and have to determine their identity with chemical tests.

Learners mix a solution containing luminol and copper with a fake blood solution. A chemical reaction between the luminol solution and fake blood (hydrogen peroxide) show learners a blue glow.

Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.

Learners use a simple process to extract DNA from strawberries.

Learners observe an electrochemical cell constructed from a small jar containing zinc and copper strips immersed in separate solutions. The strips are connected to a motor that turns a small fan.

In this activity, learners create a mixture of water, alcohol and permanent marker ink, and then add salt to form a colored alcohol layer on top of a colorless water layer.

Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.

Learners add two dyes to mineral oil and water, and then compare their miscibility (how well they mix) in each.

In this chemistry demonstration, acid rain is simulated in a petri dish.

Learners design their own experiment to investigate how pollution diffuses through ground material.

Learners add acid rain (nitric acid) to two cups that represent lakes. One cup contains limestone gravel and the other contains granite gravel.

In this experiment, learners will conduct chemical and physical tests to identify mystery substances.

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.

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.

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.

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.

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.

In this engineering design activity, learners will design, test, and build a “haunting machine” to solve a Sherlockian mystery.
