Learners explore water's property of cohesion through two investigations.

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

In this chemistry activity, learners use thin layer chromatography to determine the molecular composition of different markers.

In this activity, learners investigate how different materials repel or absorb water. Learners use spray bottles to explore how everyday items like sponges, cardboard, feathers, etc.

In this experiment, learners work in teams to investigate how the color of a surface influences its ability to reflect light and therefore heat.

Learners design their own experiment to investigate whether the temperature of the surrounding water affects the rate at which the colored coating dissolves from an M&M.

In this activity, learners investigate and compare the rate of drying in different conditions.

In this experiment, learners separate different types of molecules in marker inks (using a technique called "thin layer chromatography").

Learners will compare the growth rate and appearance of crystals forming on small rocks to those growing on miscellaneous objects. Learners will also investigate how temperature (warm vs.

Learners observe and record what happens when they manipulate bottles containing a liquid (water or corn syrup) and one or more objects (screw, nail, paper clip).

Learners demonstrate how water can distort, refract and magnify light.

In this quick activity (page 1 of PDF under SciGirls Activity: Exercise and Memory), learners will investigate what happens to bubble gum when it is chewed for 5-10 minutes.

Learners manipulate opaque, sealed boxes and attempt to determine their interior structures. Each box contains a moving ball and one or more fixed barriers.

This is an activity (located on page 3 of PDF under Hockey Sticks Activity) about composites, materials made of 2 or more different components.

In this activity, learners build a sled kite that models a type of airfoil called a parawing.

Learners apply their knowledge from a previous study to identify different liquids--water, corn syrup, and vegetable oil.

Young learners investigate and observe the properties of three liquids -- water, vegetable oil, and corn syrup. They use their senses to collect data and ask and answer questions.

In this activity, learners explore how various energy sources can be used to cause a turbine to rotate.

In this engineering activity, learners investigate the differences between the strength of bridges made from flat and round building materials.

In this activity, learners will be working with predictions with a time frame of one week, or longer. Start by planting seedlings.
