Liquid Layers
In this density worksheet, students investigate what will happen when various liquids with different densities are put into the same container. They hypothesis and make observations. Students answer 4 questions about their investigation...
Curated OER
Observing Osmosis
Students investigate osmosis using egg cells with the shells removed. In this osmosis lesson plan, students remove the shell of an egg by letting it soak in vinegar for two days. They take measurements and observe the cell. They soak the...
Curated OER
Sewer Lice
Students observe demonstrations that show adhesion, cohesion, equilibrium density, pressure of gases and solubility. In this gases lesson plan, students observe a demonstration of raisins, spaghetti, and popcorn moving up and down in...
