What Makes Water Special?
Get close up and personal with a drop of water to discover how the polarity of its molecules affect its behavior. Elementary hydrologists split and combine water droplets, and also compare them to drops of oil. Much neater than placing a...

Moving Air
In lab groups, young scientists place aluminum cans with a bubble-solution cap into different temperatures of water to see what size of bubble dome forms. As part of an atmosphere unit in preparation for learning about convection...

Extracting DNA from Living Things
Help! Someone's trying to take my DNA! An interesting lab experiment has scholars use basic materials to extract DNA. By applying ethanol, cold water, and a protease enzyme, like pineapple juice, they pull strands of DNA from peas,...
Curated OER
Osmosis
For this biology worksheet, students determine how many solvent and solute molecules there are in the red blood cell and the IV fluid. Then they determine whether the IV fluid is hypertonic, hypotonic, or isotonic to the red blood cell.

Investigating an Enzyme-controlled Reaction: Catalase and Hydrogen Peroxide Concentration
Are you looking for a way to measure cellular respiration? Try it with pureed potatoes. With some standard high school science equipment, biologists can perform an investigation and collect data surrounding byproducts of respiration. You...
Curated OER
The Cytochrome-C Lab
Young scholars examine a method biologists use to try to determine relationships. They examine how amino acid sequences have been determined for a number of proteins, and how scientists can make inferences about DNA based on the amino...

Chromatography
Advanced techniques for the lab use of chromatography are detailed here and your students will learn the specifics of separating molecules using a staionary and mobile medium. Diagrams of the equipment used and some facts about how...
Curated OER
Polymers
Students explore online tutorial on polymers. In this chemistry lesson, they create two polymers in the lab and compare their properties. They write a sales letter about their new and improved polymer product.

When Silicon Talks
Explore Snell's Law using thin films. In the fifth installment of a seven-part series, pupils solve a set of problems relating to Snell's Law and use this skill during an experiment requiring the collection of reflective measurements...

Smelly Balloons
Students investigate the concept of diffusion through a membrane. They do this through the conduction of a simple experiment. Students make observations while determining if the smell of different chemicals seeps through the balloon...
