Statistically speaking, the content covers several grades. Featuring all of the statistics typically covered in a college-level Statistics course, the expansive content spans from sixth grade on up to high school. Material...

Learners complete a virtual lab to test for a corn mold that can lead to dangerous toxins. They walk through a detailed step-by-step procedure then see their findings. Throughout the activity, they learn how to use lab tools and practice...

Scholars explore the procedure for bacteria sampling in a virtual lab by first walking through a detailed step-by-step procedure of preparing the samples of raw milk and pasteurized milk, growing the bacteria, and comparing results....

Scholars use a lab simulation to test contaminated yogurt for bacteria by gram staining. They learn proper lab procedures for handling bacteria and for sterilizing equipment, and then walk through the process on their own to try gram...

Food storage matters! Scholars learn how the amount of water in corn can affect its rate of spoilage. They create a control group, then test three corn samples stored in three different locations for water activity. As a result of the...

Teach the class how to use a microscope to identify bacteria in food. Scholars explore the different parts of the microscope and learn how to determine total magnification. They walk step-by-step through the procedure of preparing slides...

How does water activity play a role in food spoilage? First, the learners think about which types of foods would be best to take on a backpacking trip based on the water activity of different foods. It then walks through why water...

What are the different ways to test for pH? First, scholars explore the pH scale and a common way to test for acidity and alkalinity. Then, they learn about the importance of pH in food safety and why variance in pH could potentially...

Have a popping good time. Using probability and statistics skills, learners determine which type of popcorn to buy based on the percentage of kernels popped. After analyzing corn and popcorn sales to make a prediction of future sales,...

Scholars collect data from heating sand and water before forming testable hypotheses about why sand heats up faster. Afterward, they develop and run experiments to test their hypotheses.

Help your classes find the significance in this lesson! Learners analyze the probability of Diff values. They then determine if the difference is significant based on their probability of occurrence. 

Pupils analyze group data to identify significant differences. They use simulation to create their own random assignment data for comparison. 

Communicating results is just as important as getting results! Learners create a poster to highlight their findings in the experiment conducted in the previous lesson in a 30-part series. The resource provides specific criteria and...

Wiggle your way through lab day! Young zoologists observe and infer the effects of different stimuli on earthworms during an engaging lab from the K20 series. Lab partners set up four different controlled environments, then record how...

It's an extravaganza of excrement! Do your pupils understand that waste doesn't really go to waste? Introduce the nitrogen cycle with an interesting instructional activity and lab from the K20 series. The activities include a look at...

Seventh graders compare experimental and theoretical probabilities.  In this comparing experimental and theoretical probabilities activity, 7th graders discuss the theoretical probability of flipping a coin.  Students flip a...

In this speed and experiments worksheet, students read about how to calculate the speed by using the change in distance divided by the change in time. They also read about experimental design and scientific method. Students match 5 terms...

Learners focus on a force and motion problem, explore it, reflect on it and apply it while completing experiments.  In this motion lesson, students experiment with force and motion by creating a track for testing cars.  

In this project worksheet, students complete a formal write up of their experiments. This includes a rationale, a purpose, a hypothesis, their experimental design, materials, procedure, data tables with variables, graphs and a concluding...

In this weathering, erosion and deposition worksheet, students answer questions about the causes of weathering, the types of weathering such as mechanical and chemical weathering and resistance to weathering. They also write two...

In this experimental design learning exercise, students fill out their title, hypothesis, independent and dependent variables, data table, graph and conclusion for their lab.

Students identify the physical needs of animals and if plants need the same things as animals. They conduct an experiment to see if plants need light and water to grow. They compare the growth of the plants exposed to the different...

Seventh graders study microorganisms in their environments by experimenting with milk products. In this microbes lesson, 7th graders read background information about microorganisms in yogurt and soured milk. Students then follow a...

Students gain an understanding of the real world applications of the scientific method. They design their own experiments to prove or disprove the existence of other modern legends, and they design and carry out an experiment to test a...
