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...

How long do fresh foods last in space at the International Space Station? Which foods perish quicker than others? How can astronauts preserve their foods to make them last longer in space? Young scientists test the rates at which...

Got milk? Only two cultures have had it long enough to develop the tolerance of lactose as an adult. Learn how the responsible genes evolved along with the cultures that have been consuming milk. This rich film is supplied with a few...

On Earth, a candle flame points up, but on the International Space Station, it forms a sphere. Young scientists practice their skills by recording observations before, during, and after a candle burns. Chemical and physical...

Model how the sun's energy strikes the planet and help your class relate it to a climate map. Assign small groups an individual climate zone to discuss. They reflect on and research how humans survive in the assigned climate and write a...

With a partner, youngsters measure their pulse and breathing rates, both at rest and after running in place for a minute. While this activity is not novel, the lesson plan includes a large-scale classroom graphing activity and other...

How does the scientific process begin? Introduce ecology scholars to scientific inquiry through an insightful, data-driven lesson. Partners examine data from an ongoing research study to determine the questions it answers. The resource...

Small groups investigate plots of land to discover how abiotic and biotic factors interact. After recording their findings, scholars share observations with peers and self-reflect on the learning process. 

The reintroduction of a species to an area doesn't always go as expected. Scholars learn about the reintroduction of wolves into Yellowstone National Park with a video, reading, and discussion questions. They complete a hands-on activity...

My room isn't messy — it's a scientific experiment in entropy! Scholars investigate entropy, enthalpy, and spontaneity through a guided procedure and set of questions. The lesson connects the Second Law of Thermodynamics, energy...

More than half the world's population eats rice as a daily staple ... imagine if that rice could prevent illness. Scientists genetically engineered rice to include vitamin A for just that purpose. However, room for debate still exists....

How does energy from the sun make plants grow? Scholars move step by step through the processes that promote plant propagation during a detailed lesson. The resource illustrates ADP production and hydrolysis, then allows learners to...

Provide your class with the opportunity to view our carbon cycle close up. Young scientists research the cycle of oxygen as it completes the tasks of photosynthesis and respiration. They explore the importance of carbon in an ecosystem...

Stephen Perry invented and patented the modern rubber band in 1845. Young scientists put his discovery to work as they use rubber bands to observe entropy and enthalpy. They determine the change in free energy to figure out if it...

Are you looking for lab sheets to go with your class experiment on plant response to light? You are no longer in the dark! This is a lesson that was written for a unit on light, but could easily be used to demonstrate plant behaviors in...

Forming ethical arguments is sometimes a complicated task. Guide classes through a process for forming and presenting ethical opinions. Learners consider the views of all stakeholders on the impact of farming on the environment and the...

Do you have young scientists wanting to make new discoveries rather than just completing the same experiments? Young scientists use their observational skills to identify animals and patterns in animal behavior. Through tracking...

Using NASA's Live Access Server, earth scientists compare the temperature, precipitation, and normalized difference vegetation index for four different locations. They use the data to identify the climate zone of each location using...

Different types of mutations cause unique types and degrees of muscular dystrophy. Scholars learn about the types of mutations and the impact on the body. They compare the location of the mutations and draw conclusions about how it is...
