Curated OER
Laboratory - Density of a Material
Middle schoolers conduct a lab (with water, guar gum and sodium borate) and carefully record physical and chemical properties and changes throughout the session, and experiment with weighing by difference.
Curated OER
Cross-Linked Polymer Lab
Students use short-chain polymers and borate ions to produce cross-linked polymers in the lab. In this cross-linked polymer lesson plan, students produce polyvinyl acetate slime and polyvinyl alcohol slime and test their physical...
Curated OER
Multi-Vitamins
Hear is a close-up inspection of some of the compounds found in the Centrum Multi-Vitamin. Each slide shows the steps required for forming one. The compounds are as follows: chromium (III) chloride, cupric sulfate, manganese (III)...
Curated OER
Cross-Linked Polymer Lab
In this polymer instructional activity, students make two types of cross linked polymers and they test their physical properties. These include their response to agitation, stretchability, viscosity, and resilience.
Curated OER
Density Of A Material
Students determine the density of a material created in the laboratory and observe physical and chemical changes. They engage in a lab activity, and answer questions on a worksheet imbedded in this plan.
Curated OER
Playful Polymers
Eighth graders investigate polymers and their structures. For this polymers lesson, 8th graders perform 6 activities to learn about polymers and their molecular structure. They categorize a bag of items as polymers and non-polymers based...
Curated OER
Superballs
Pupils mix two different solutions to become more familiar with molecules and polymers. In this chemistry lesson, students decide whether or not the reaction between two solutions is chemical or physical. Pupils then observe the newly...
Curated OER
Make A Crystal Snowflake!
Students make a crystal snowflake decoration out of string, pipe cleaners, food coloring, boiling water, and more. In this snowflake lesson plan, students let it dry over night and see crystals in the morning.
Curated OER
Formulas
There are two sheets here, with 100 problems total. The first half is a list of compounds, and your young chemists should write the chemical formula for each. The next fifty give the formula and the name is required. You could also use...
Curated OER
Plant And Animal Cells
Pupils identify parts of plant and animal cells and describe the functions of each part. They distinguish between plant and animal cells. After a lecture/demo, students perform experiments which help them construct models of plant and...
Curated OER
Molecular Explorations
Students explain the processes for separating DNA from tissue and separating complex mixtures. In this exploratory lesson students complete a lab where they extract DNA.
