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

Learners observe and conduct experiments demonstrating the different properties of hot and cold materials.

In this activity, learners explore how to protect their skin while applying pesticides to plants.

This modeling activity allows learners to discover for themselves what Mendel uncovered in his famous pea experiments.

In this activity (Page 30 of PDF), learners investigate the evolution of wheat by conducting sedimentation tests on different flours.

Learners see that a carrot slice sinks in fresh water and floats in saltwater.

In this chemistry demonstration, learners will discover that phenolphthalein is a chemical that displays different colors depending on the acidity or basicity of the environment.

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.

In this introductory demonstration and activity, learners are introduced to the concept of density as they explore a rock and a wooden block in water.

Learners will see that changing the shape of an object, like a clay ball, that is more dense than water, can affect whether the object will sink or float.

In this quick activity (page 1 of PDF under SciGirls Activity: Hockey), learners will use a simple physics of motion and gravity demonstration to test their predicting skills.

In this activity, learners explore how salt water freezes in comparison to fresh water.

This three-part activity consists of an activity that groups of learners develop themselves, a given procedure, and an optional demonstration.

Learners use a universal indicator to test the amount of sodium hydroxide needed to change the pH of plain water compared with the amount needed to change the pH of gelatin.

In this chemistry demonstration, learners investigate the rule "likes dissolve likes" by combining three, immiscible liquids to create a colorful density column.

Learners use a mortar and pestle to extract clove oil from cloves using denatured alcohol. They put this oil on paper, which they can take home.

In this chemistry activity, learners observe a combustion reaction and deduce the components necessary for the reaction to occur.

In this chemistry demonstration, learners observe a chemical reaction that produces a colorful effect.

In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.

In this activity, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.
