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

In this multi-part activity learners examine non-point water pollution.

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

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 activity, learners collect, analyze, and interpret information about objects in order to classify them into a cladogram. Use this activity to talk about how scientists classify things.

In this outdoor activity, learners investigate the relationship between the slope of a trail and soil erosion.

In this activity, learners examine body parts (including skin, scales, and skulls) from fish, mammals and reptiles. Questions are provided to help encourage learner investigations.

In this outdoor activity, learners search for lichen, a combination of a fungus and an alga living together. Lichen grow where most other plants cannot, on rocks, the trunks of trees, logs and sand.

In this activity, learners participate in a scavenger hunt, searching for and recognizing minerals and products that contain minerals.

In this activity, learners investigate color vision as well as plan and conduct their own experiments.

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

In this activity, learners investigate the different salinity levels of oceans, rivers and estuaries.

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.

In this outdoor biology and math activity, learners estimate the size of a population of organisms too numerous to count.

In this outdoor beach activity, learners use a variety of "beaks" (such as trowels, spoons or sticks) to hunt for organisms that shore birds might eat.

This is an activity which will allow learners to gain an understanding of lemur behavior through observation and role play.

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).

In this activity learners observe mold growth on different types of bread by measuring and recording the growth rate.
