Density of a Gas
Eighth graders investigate the mass, volume, and density of a gas by producing it in a chemical reaction. The entire Density of a Gas Lab and L section of the K W L chart be formatively assessed.
Curated OER
Sink or Swim
Students define density and explain how to determine the density of an object. Students participate in a demonstration that shows the differences in the densities of different liquids and how they affect the liquid's physical properties.
Curated OER
Laboratory - Density of a Material
Students 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
Efficiency Means Getting More for Less
Students measure water and make predictions about efficiency.
Curated OER
Herb is the Word
Middle schoolers conduct an experiment to determine how different soils affect plant growth over a six-week period. After determining the physical properties of different types of soil, students plant various types of seeds into the soil...
Curated OER
States of Matter: Liquid
Students work in a mini lab where they measure the temperature every 30 seconds for several minutes as water is heated. They are asked what makes liquid different from a solid. Students view a PowerPoint on the model of liquids,...
Curated OER
Physical Difference and Classification
Students use a microscope and observation skills to compare and contrast several physical properties and develop a classification system.
