Light Waves: Grades 6-8
Explore the behavior of light with different materials. Collaborative groups determine whether certain materials absorb, reflect, diffract, or transmit light waves. They then measure the angle of incidence and angle of reflection.

Changing State: Condensation
When you have a cold drink and you notice the water forming on the outside, it is literally pulling the water from the surrounding air to form the condensation. After watching a demonstration of condensation forming on a glass,...

Doing Lewis Dot Diagrams
Students observe the periodic table and draw the Lewis Dot Diagram. In this investigative lesson students construct information on several elements including the Lewis Dot Formation and take a quiz on the information they learned.
Curated OER
What is a Nanometer?
Students develop a concept of the relative size of objects in the nanoscale. They complete an internet assignment using the website,"Scaling the Universe to Your Desktop". Using analogies to common objects they get an appreciation for...
Curated OER
Designer Genes
Students view a video on DNA. They discuss mitosis, meiosis and fertilization. They use strips of paper to simulate fertilization and analyze the genotype and phenotype of the combined chromosomes.
Curated OER
Lactose & Lactase
Students examine the characteristics of lactose and lactase. For this enzyme lesson students study the lactose in milk and its rate of dissolution.
Curated OER
Necessary Nitrogen
High schoolers view a video that presents the biogeochemical cycle of nitrogen. They compare types of soils and consider how different fertilizers affect soil composition.
