In this activity related to microbes, learners use water drops and hand lenses to begin the exploration of magnification. This activity also introduces learners to the microscope.

Learners carefully pour vegetable oil, water, and corn syrup in any order into a cup and discover that regardless of the order they are poured, the liquids arrange themselves in layers the same way.

In this activity, learners combine two substances (plaster of Paris and water) to make a cast of an object's imprint in clay.

In this activity, learners make a model of a one-way heart valve to investigate how a heart controls the direction of blood flow.

This is an activity (on page 2 of the PDF under Bone Regrowth Activity) about the two main components of bone - collagen and minerals (like calcium) - and how they each contribute to its flexibility a

In this fun hands-on activity, learners whip up a batch of cyber-dough (play dough) using math for measurements.

In this activity related to the human circulatory system (on page 10 of the PDF), learners observe the dispersion of a drop of food coloring in water, draw conclusions about the movement of dissolved

Bones are stiff, which helps us lift heavy things and walk around, but they are also somewhat flexible, which lets them bend slightly.

In this activity on page 7 of the PDF, learners explore how engineers characterize building materials.

This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.

This kinesthetic science demonstration introduces learners to four states of matter: solid, liquid, gas, and plasma.

In this hands-on science experiment, students combine their understanding of the different states of matter and the characteristics of various chemical reactions.

In this activity (on page 2 of PDF), learners create a low-tech refrigerator that requires no electricity to keep food from spoiling.

In this archaeology activity, learners consider ways in which excavating an underwater site is different from excavating a terrestrial site.

In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.

In this math lesson, learners compare products to determine the best product.

In this activity, learners investigate the food, water, and space needs of common livestock animals.

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

In this two-part activity, learners investigate buoyancy, density and surface area as well as biodiversity and the relationship between the structure and function of organisms.

In this four-part activity, learners explore how the body works and the chemistry that happens inside living things.
