How Much Do I Know About Water?
Sixth graders explore ways to analyze the properties of water and examine the chemistry of water. In this water lesson students work in groups and complete several activities.
Cornell University
Atomic Bonding
Explore the connection of surface area to bonding within atoms. Learners complete lab investigations to model changing surface area with different sizes and concentrations of atoms. A flour fireball demonstration follows the labs to...
Cornell University
Polymerization
Explore condensation polymerization and additive polymerization through hands-on activities. Young scholars first model additive polymerization with paperclips. They finish the activity by using condensation polymerization to create a...

The Marvels of Mud
Young scientists roll up their sleeves and get a little dirty in this three-day earth science investigation. Following the scientific method, children monitor the growth of algae in pond water samples in order to determine the role that...
Curated OER
Semipermeable Membranes and Bioaccumulation
Beginning biologists place a drop of food coloring into water of differing temperatures to observe the effect on the diffusion rate. They remove the shells from raw eggs and then experiment with osmosis over the remaining membranes....
Cornell University
Discovering Enzymes
Explore the function of enzymes through a series of lab investigations. Learners use household enzymes such as hydrogen peroxide to model the role of enzymes. The enzymes break down proteins with and without a catalyst.
Curated OER
Molecular Origami
Students construct an origami models of different molecules. In this chemistry lesson, students explain what expansive soils are made up of. They discuss what happens when this expansive soil expands or shrinks.
Curated OER
Pauli's Magical Water
Pupils predict the shape of molecules using VSEPR theory. For this chemistry lesson, students differentiate a polar and nonpolar molecule. They discuss why water's polarity is very important.
