The Basics of Biochemistry
Science teachers can introduce basic chemical concepts to biology students.
Curated OER
Gas Transport
In this biology worksheet, students examine the transport of gases in the circulatory system and how they bond to hemoglobin.
Curated OER
Chemistry Module
Students build metal atomic models using styrofoam. In this chemistry lesson, students identify the different unique properties of metals. They explain how metal atoms bond.

The Influence of Initiator Concentration on the Molecular Weight of Polystyrene
This in-depth organic chemistry lab walks learners through an investigation of the effect of initiator concentration on the resulting molecular weight of polystyrene. It is important that you use this lesson with experienced chemistry...
Curated OER
Intrinsic Viscosity
Students treat a high molecular weight polyvinyl alcohol polymer with potassium periodate. They measure the viscosity of polyvinyl alcohols.
Curated OER
What is pH?
Pupils describe pH and the importance of it in the natural world. In this Biology activity students compare the pH of different mixtures.

How Genes Work Lesson Plan
High schoolers define the key terms that are the structure and function of DNA. In this genetics lesson plan students complete a lab activity in which they construct a model DNA structure.
Curated OER
What Color is Chlorophyll?
Students observe the interactions of chlorophyll and light. They develop and form their own testable hypotheses. Students predict the color of chlorophyll in various types of plants.
Curated OER
Ozone Tag
Seventh graders explain the role of stratospheric ozone and predict at least three ways in which depleted ozone would change her/his lifestyle. They then describe the process by which chlorine or bromine compounds can break down ozone...
