Density Lab
For this biology worksheet, students use the website given to become familiar with the equipment of a lab. The activity involves a link to a virtual laboratory. Then they determine an objects mass and volume by placing it in a graduate...
Curated OER
Testing the Waters
Eleventh graders examine a local body of water. In this science lesson, 11th graders collect water samples to test. Students analyze the data and make conclusions. Students create tables and graphs of the data.
Curated OER
The Effects of Water Quality on the Growth Rate of Freshwater Mussels
Students participate in a field and laboratory study to determine if local freshwater mussels are environmentally stressed.
Curated OER
Soil Analysis Lesson Plan
Learners practice calculating density and examine examples of the physical characteristics of soil. They solve a "crime" based on the evidence and laboratory investigations.
Curated OER
Candy Cane Chemistry
Fourth graders, in groups, examine the effect of heat on bonding forces by doing laboratory work.
Curated OER
Dissect with Respect
Students, through exercises and discussions, examine ethics involved in the process of choosing and using laboratory animals, respect for the animal they dissect and how to behave in an ethical manner as they dissect various lab specimens.
Curated OER
Work and Energy
Young scholars show that energy is conserved in the laboratory. They calculate the work done by a force on an object as the product of the force and a displacement of the object from a reference point.
Curated OER
Rainbow Electrophoresis
Students are introduced to the principles of gel electrophoresis and also provides an opportunity for students to practice loading gels and prpetting. In this laboratory activity, food color is used to separate into constituent pigments.
