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...

The sun sends the earth 35,000 times the amount of energy required by all of us on the entire planet, every day. The fourth lesson in the 10-part series looks at how light energy from the sun transfers into thermal energy. Scholars build...

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. 

How does food coloring work? Classes watch a demonstration showing liquids dissolving in liquids. In groups, they then explore the ability of other liquids to dissolve in water (alcohol, mineral oil, and corn syrup) by setting up and...

Keep everything under control. The instructional activity, the 16th segment in a 22-part unit, provides a more detailed look at the parts of a plane, specifically the control surfaces. Pupils learn about the construction of the wings and...

Laws of motion apply both in space and on Earth. Young experimenters model object impact on the Earth and moon. They use data to determine the effect mass and velocity have on the resulting craters and how that relates to the energy of...

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...

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...

Bring the resource out from the shadows. Viewers of a short video learn about drive-in theaters and how operators project images onto a large screen. They then perform an experiment to determine the relationship between the distance of...

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...

While many mutations are neutral, those that appear advantageous increase in frequency in a population. Scholars use illustrations to make predictions about populations of mice. They follow it up with a video to confirm or refute their...

Alia-Seltzer tablets cause a very obvious chemical change, but do they also cause a temperature change? Each class member explores hot/cold packs, discussing how these temperature changes occur. Groups then design and carry out their own...

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...

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...

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...

When making sweet tea, why do people dissolve the sugar in hot tea instead of cold tea? The class discusses the previous lab and builds upon it. Working in groups, they design an experiment to determine how temperature affects the...

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...

A truly hands-on and inquiry based learning activity bridges all the lessons in the series together. Beginning with a discussion on average global temperatures, young meteorologists use real-world data to analyze climate trends in order...

Students explore algebraic concepts using real life situations.  In this equations lesson, students develop strategies to solve missing number problems. Students participate in a board game based on algebraic equations.

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...

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...

Each of the Earth's spheres interacts with the other spheres in predictable ways. Young scientists explore these interactions through a hands-on activity, graphing, and watching a video. They summarize their knowledge in a video or...

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...

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...
