Lab 2: Nanocatalysts Clean Your Car Emissions
Surface area certainly surfaces as a variable for chemical reaction rates. Scholars perform an experiment to discover how the size of catalysts affect the rate of a chemical reaction. They record their results in tables and graphs to...
Curated OER
Transpiration
Students explain the function of the hydrologic cycle and demonstrate how transpiration rates can be experimentally changed.
Curated OER
What Causes the Seasons?
Students conduct experiment to examine how tilt of globe influences warming caused by lighted bulb. They monitor simulated warming of their city by sun in winter and in summer by using light bulb, interpret results, and submit lab report.
Curated OER
Mass
Students participate in a qualitative discussion of the distinction between weight and mass, followed by a description of astronaut mass measurements in a zero-g environment.
Curated OER
Great Gravity, Batman!
Eleventh graders are introduced to the effect of gravity on plant growth. They describe the major processes and mechanisms by which plants grow, develop, and supply various products, including energy and nutrition, needed by other...
Curated OER
Flying Tube
Students investigate how a spinning paper tube generates lift as it travels forward.
Curated OER
Simple Machines, Odd Machine
Students explore six simple machines and locate them operating in a compound machine. The simple machines are identified at a variety of stations set up in the classroom and continued by identifying the machines in their homes.
