Chemical Bonding
Eighth graders identify the three main types of chemical bonds. In this chemistry lesson, 8th graders draw Lewis dot diagrams of elements and determine the bond formed. They create a model water molecule.
Curated OER
"Pennsylvania Watersheds, Many Ways to the Sea"
Students trace a molecule of water through the water cycle including each of its three loops. They describe why evapotranspiration demands the largest portion of total precipitation falling on a forested watershed.
Curated OER
Molecular Architecture
Students cuminate their study of molecular structure and bonding with this activity.
Curated OER
Carbon: Structure Matters
Young scholars read the Who We Are Section on Calfee Designs Webpage and discuss carbon usage. They work in pairs to look up the minerals diamond and graphite then create a chart on the properties of each mineral then compare how they...
Curated OER
Homologous Shoes
Students examine the concept of homology by observing their shoes and those of their classmates. They summarize the observations of everyone's shoes relating it to chromosomes in cells. They share their observations with the class.
Curated OER
Constructing a Phylogenetic Tree
Students are given the opportunity to analyze DNA sequence differences between organisms in order to establish a reasonable picture of the evolutionary relationships between them (Phylogenetic Tree). In the simulation form they are...
Curated OER
An Introduction to DNA (PowerPoint)
Students are introduced to the structure of DNA, nomenclature, and the chemical basis for DNA through a PowerPoint lecture. PowerPoint is included as well as review questions over the presentation.
Curated OER
New York City Water Quality Assessment Project
Students investigate the chemistry of water and how its molecular structure supports life through its biochemcial, physical, and environmental roles. They investigate the quality of water as it interacts with the environment. Students...
Curated OER
Demonstrating the Kinds of Energy
Students experiment with inner tubes, weights, flasks, and pistons to demonstrate the gas laws. In this molecular motion lesson, students demonstrate pressure as a force per area. They conduct an experiment to show the relationship...

Math Morphing Proximate and Evolutionary Mechanisms
High schoolers identify the different types of fractals. In this geometry lesson, students use math to analyze different biological phenomena. They collect data from the experiments and construct graphs.
Nuffield Foundation
Microscale Investigations of Catalase Activity in Plant Extracts
Use indirect measurements to monitor metabolic activity in plant cells. Scholars understand that cells with a higher metabolic rate have a higher concentration of catalase enzyme. They use this information to compare metabolic rates of...
Nuffield Foundation
Investigating the Effect of Temperature on the Activity of Lipase
How does temperature affect lipase activity? Young scholars conduct an experiment to collect data on the interaction of lipase at different temperatures. They add lipase to a solution of milk, sodium carbonate, and phenolphthalein and...
Curated OER
DNA Replication
High schoolers work with a partner to answer any unanswer questions on their review sheet. They work in groups of 4 to make flash cards as study aides. Students play a review game for the remaining of the class period. The winning...
