Become a bean counter. Pupils use a fun activity to design and execute an experiment to determine whether they can grab more beans with their dominant hand or non-dominant hand. They use the class data to create scatter plots and then...

Equip your chemistry class with the tools to properly understand endothermic and exothermic reactions. Young chemists collect, analyze, and graph data to determine how the Law of Conservation of Matter is applied to chemical...

Turn up the heat! Young mathematicians develop models to represent different climates and collect temperature data. They analyze the data with regression and residual applications. Using that information, they make conclusions about...

Is time on your side? Pupils come up with an experiment to test whether their classmates can guess how long it takes for 30 seconds to elapse. They divide the class data into two groups, create box-and-whisker plots, and analyze the...

Caffeine affects your heart rate — or does it? Learners study experimental design while conducting their own experiment. They collect heart rate data after drinking a caffeinated beverage, create a box plot, and draw conclusions....

Why do athletes load up on carbohydrates the evening before a competition? The lesson helps answer this question as it relates the type of food to the amount of energy it contains. After a discussion, scholars perform an experiment...

Although the methods are all scientific, forensic science was started by police officers rather than scientists, who relied on observation and common sense. Young detectives use many tools to solve crimes around the school in a...

Class members analyze the water content in soil samples by drying out the samples and taking measurements every minute until all the moisture is gone. Scholars compare the initial weight to the dried weight to calculate the percentage of...

How diverse are the benthic organisms found in local streams? Using the information learned in previous lessons on identification of macroinvertebrates and on calculating stream index values, groups determine the health of local...

Does mass change during a chemical reaction? Demonstrate the Law of Conservation of Matter while encouraging class members to be creative with a two-part lesson. First, learners use Alka-Seltzer® tablets and water to demonstrate the...

Class members engage in a STEM experiment and investigate how materials affect heating in a house by creating models of houses and using different top surface materials. They record the temperature inside the models and consider what the...
