How did ancient peoples determine the height of really tall objects? Young scientists and mathematicians explore the concept of using shadows to measure height in a hands-on experiment. Paired pupils measure shadows, then calculate the...

Reinforce concepts and encourage learner engagement with a collection of math games, science experiments, and cross curricular activities. In one fun resource, learners sort objects, keep a diary of everyday fractions, play a game using...

Are you nuts? An engaging experiment burns nuts to find their kilocalories. Young chemists analyze at least two different types of nuts with their experimental results versus what is on the package. The resource offers a great lab...

With rising oil prices and increasing concerns over global warming, the pressure is on for engineers to develop alternative sources of energy. Among the new technologies being developed are hydrogen fuel cells, which young scientists...

Stop wasting energy searching for physics resources, this comprehensive collection of worksheets has you covered. Starting with introductions to the scientific method, dimensional analysis, and graphing data, these skills practice...

Future statisticians and potential psychics first conduct an experiment to collect data on whether a person can tell if someone is staring at them. Statistical methods, such as hypothesis testing, chi-square tests, binomial tests, and...

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....

Herbivores and carnivores just don't get along. Using a box of animal crackers, classes collect data about the injury status of herbivores and carnivores in the box. They complete the process of chi-square testing on the data from...

An educational lesson allows young chemists to test the solubility of different types of salt at various temperatures. Groups create a graph using data from unsaturated, saturated, and supersaturated solutions.

Can scientists really predict genetic outcomes or are they simply making a lucky guess? Scholars first learn about Gregor Mendel and how to make Punnett squares. Then they extract DNA from a strawberry in a lab with included conclusion...

Which materials are best for groundwater runoff, and which are best for percolation? Discuss the water table with several experiments about different types of soil, pollution, precipitation, and filtration. The experiments assign...
