Density and Miscibility
The liquids did not mix — so what do density columns have to do with it? The seventh part in a series of nine provides the theoretical explanation of why density columns do not mix. The activity covers the topics related to mixing and...
Curated OER
Strong Ice
Through three activities, first-time physical scientists wonder at the properties of water. Freeze some soda cans and a container of water prior to the investigation to show that water expands when frozen. Lab groups experiement with...
Curated OER
Denaturing Proteins
Students investigate how to denature proteins. In this denaturing protein lesson plan, students explore the different ways to denature proteins in the lab. They use heat, acids and bases, organic compounds and heavy metals to denature...
SRI International
Science of Water
Water is crucial to survival. Scholars gain an appreciation for water by reading about it, learning about its atomic properties, and investigating its properties through six stations in a lab activity.
LABScI
Enzymes: The Spit Lab
Enzymes in our bodies each have a job to do. Learn the factors that affect the activity of some enzymes using the third activity of an informative 12-part biology series. A three-part laboratory activity asks teams to investigate how...
Virginia Department of Education
Physical and Chemical Properties of Water
How can you effectively provide detailed concepts of water properties to your high school class in a way they find exciting and challenging at the same time? By letting them play, of course! Through a variety of experiments, pupils...
Curated OER
The Four Groups of Biologically Important Compounds
This is not they typical set of teacher instructions. It is an organized chart of the important organic compounds. For each, the involved elements, the name of the building block monomers, the names of polymers, extra information, and a...
Santa Monica College
Lewis Structures and Molecular Shapes
Learners practice drawing Lewis dot structures, build molecules with model kits, and predict molecular shapes using VSEPR theory. The combination of written work and hands-on reinforcement benefits young scientists.
Curated OER
Polymerization Experiments
Students study the concepts of polymerization and the function of crosslinkage. For this polymer lesson students complete a lab activity and write down their observations.
American Chemical Society
Why Does Water Dissolve Sugar?
Did you know that if you wait long enough, the M on the outside of an M and M will float to the surface when submerged in water? Learners observe the sugar coating of an M and M while it is dissolving in water. They explain how this...
Curated OER
Titration Lab
Students determine the concentration of an unknown solution using titration. In this chemistry lesson, students explain the difference between acids and bases. They discuss the role of indicators in titration.
Curated OER
Mechanical, Electrical and Radiant Energy
Pupils write a hypothesis and complete a lab. In this investigative lesson students complete their lab and a worksheet about energy.
Curated OER
Water and Polymers
Learners conduct qualitative and quantitative investigations based on the interaction between water and various polymers. They determine the percent moisture contained in various plastics along with a qualitative procedure to determine...
Curated OER
Surface Tension (Soap Boat)
Young scholars investigate the affect of soap and water temperature on surface tension.
Curated OER
The Effects of Temperature on Chemical Mixtures
Students explore chemical cahnges and the effect of temperature on chemical mixturees, They make observations of the behavior and appearance of certain chemical mixtures and reactions.
Curated OER
It's the Slime Time
Students experiment to understand the basic concept of polymerization and to understand the dissolution theory. Student experiment with polymers to understand its behavior and the mechanical behavior of polymer networks.
