EGG-cellent POLYMER PACKAGING DESIGN
Students investigate the concept of a polymer using an experimental design of protecting an egg in a bookbag. They test the properties of polymers and form an educated solution to the proposed problem. Then they describe the steps used...
Curated OER
Science with Mud!
Eighth graders give some examples of chemical reactions they see everyday. In this chemistry lesson, 8th graders investigate how much water soil can hold. They collect data and compare results with others.

Science: What Happens to Create the Lode?
Students understand how mineral deposits are formed and why they are not evenly dispersed. They create and describe three different precipitates from four solutions simulating mineral ore deposit formation in sedimentary rock.
Curated OER
Micro-Magic With Sticky Ions
Learners view a video about the formation of precipitates. They complete a worksheet that asks them to identify what makes a compound form and what holds it together.
Curated OER
Nutrient Biochemistry
In this lipids worksheet, students review the different types of lipids and how lipids are used by the body. This worksheet has 3 drawings and 27 fill in the blank statements.
Curated OER
Understanding of the Structure of an Amino Group
High schoolers review the characteristics of acids and bases. They examine the structure of an amino group and compare amines to ammonia. They work together to develop the concent of polymerization.
Curated OER
Solar
Students study solar energy. For this renewable energy lesson students complete several lab activities using different controls and variables.
Curated OER
Ozone Tag
Students 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 molecules.

Super Glue Fuming of Latent Fingerprints
Students explore latent fingerprinting. They observe a supervised demonstration of the process that real-life crime scene investigators sometimes use to identify latent fingerprints. In addition, they brainstorm ways to improve the...
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
Molecular Models of Functional Groups
In this molecular model worksheet, students use a molecular model kit to construct 13 different molecule models. After constructing the molecules, the students complete 32 short answer questions.
