An Investigation into Effects of Rhizobium Soil Bacteria on Nitrogen Availability
Students identify the control and the variables in the experiment. They describe the growth of plants with and without nitrogen fixing bacteria, then name the bacterium responsible for making nitrogen available to the plant.
Curated OER
Succession and Experimental Process
Students describe the roles of controlled, manipulated and responding variables in scientific research. They also identify biotic and abiotic interactions affecting the makeup of a plant community.

What's the Matter with My Jell-o?
Students work in teams of four as they conduct four controlled Jell-O experiments over a two-day period. The Family Page extends this learning to the community by providing families with challenges to explore at home.
Curated OER
Mountain Building
Fourth graders identify variables that influence rates of change. They, through group consensus and using the assigned materials, design and build what they believe to be the strongest mountain possible.
Curated OER
Investigating the Biosphere with Planetary Models
Students model the biosphere and manipulate variables affecting change and plan their experiments with the help of others. They describe their question, hypothesis, and methods of investigation.
Curated OER
Using Graphs to Compare
Pupils use the FoilSim computer simulation program, and demonstrate an understanding of the lift variables by explaining their graphical representations. They demonstrate an understanding of forces and motion.
Curated OER
Lotic Environment
Students assemble a classroom river model as an example of a lotic system. They control and measure biotic and abiotic information for the in-class system and compare data with a lotic system in a natural environment.
Curated OER
Night Creatures of the Kalahari
Learners conduct an experiment to demonstrate how fruit fly populations are controlled by spiders. They observe a variety of environments with fruit flies and spiders and consider how vital spiders are to controlling the insect population.
Curated OER
Code Crackers
Students work in teams creating and posing math rules and trying to guess them using a formula controlled worksheet they create with Excel. Student pairs take turns to see who can crack the other's code the fastest.
Curated OER
Examining Infiltration Rates of Various Soil Types
Students formulate their own hypothesis, determine which variables are important to test their hypothesis, design an experiment in which they collect data. They utilize instruments and tools to measure, calculate, and organize data.
