Build problem-solving skills with science! Step-by-step videos walk investigators through each stage of completing a science fair project. Scientists learn to formulate a testable question, design an experiment, collect data, draw...

Have you always wanted to take your science class on an amazing field trip they will never forget? Now you can! Observe the wildlife in an African savanna through trail cameras with a five-part data analysis activity. Learners analyze...

Should athletes carb load before an event or consume carbohydrates during the competition? Scholars discuss how to set up a hypothesis and experiment to answer a question relating carbohydrates and athletic performance. Then, they read...

Young scientists roll up their sleeves and get a little dirty in this three-day earth science investigation. Following the scientific method, children monitor the growth of algae in pond water samples in order to determine...

First graders learn the basic needs of plants and identify geometric shapes while planting a fall garden. Combining math and science in one lesson, the resource guides kids through starting their class garden as they...

Enzymes play a role in almost every function in the human body. Scholars explore three variables related to the use of enzymes. They observe a catalase reaction, experiment with substrates, and examine reactions rates. 

You've heard of farm to table ... but what about farm in classroom? Junior agriculturalists embark upon a two-week journey into the science of growing things. Based upon the classic terrarium in a two-liter experiment, the instructional...

Research the impact that changes in biotic or abiotic factors might have on an ecosystem. Debate for or against the changes and take action in the community. This resource ideally follows stream studies that young ecologists may have...

How does gravity affect the life cycle of a butterfly? Learn first-hand what types of investigations astronauts perform in space by following along with one of NASA's experiments. Create butterfly habitats in the classroom with specific...

As the reality of population decline across many species becomes real, pupils learn about the variables related to changes in populations. They complete a simulation of population changes and graph the results, then discuss limiting...

If I want to build up my heart, where should I start? Science scholars use statistics in a sports physiology setting during an insightful experiment. Groups measure resting and active heart rates and develop a scatter plot that shows the...

Swimmers know to float by turning their bodies horizontally rather than vertically, but why does that make a difference? In an interesting lesson, scholars explore buoyancy and the properties of air and water. They test cups to see which...

When it comes to the environment, no variable is constant. Class members graph behavior over time for the thneeds produced over truffula trees chopped down over the course of Dr. Seuss's The Lorax. 

Role play community members who are both for and against the construction of a dam. Research the pros and cons and then hold a classroom debate. This activity ideally follows a series of stream studies, links to which are included. Use...

Transform young biologists into grasshoppers, lizards, and hawks as you teach them about food chains in an interactive life science simulation. Working collaboratively to act out three different scenarios involving...

The higher the number of letters in the final word for the National Spelling Bee, the higher the number of people killed by venomous spiders. Obviously, those two facts correlate, but no causation exists. Scholars view data based on...

Many variables impact your body mass, not just diet and exercise. Scholars collect and study data about body mass to better understand the complexity of a sensitive topic. They learn about leptin deficiency, the hypothalamus, and more.

Historians believe the first vertical water wheel was invented in Rome during the Augustan Age. The sixth lesson in the series of 10 has scholars experiment with designing their own water wheels. Through testing various pastas and...

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...

How can you store lists in a computer program? The 16th installment of a 21-part unit introduces arrays as a way to store lists within a variable. Individuals program a list of their favorite things—adding interest to the activity.

Climate systems involve sunlight, ocean, atmosphere, ice, land forms, and many other factors. Scholars explore each of these variables related to the Pacific Northwest rain forest. They use an online interactive to investigate the polar...

Stars may all look the same from down here, but their surfaces tell a different story. Using an animation, learners collect data about the temperature and luminosity of stars and compare them to their mass and radius. They then answer...

Putting glow sticks in the freezer makes them last longer, but why is that? Lesson focuses on how temperature impacts the rate of a chemical reaction. It begins with a teacher demonstration, then scholars design their own experiments...

We know that the type of soil varies by location, but does the seafloor sediment also vary, or is it all the same? Scholars compare photos of the seafloor from two different locations: the Savannah Scarp and the Charleston Bump. Through...
