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...

The pocket mouse can be light brown like the sands of the desert, or dark brown like the volcanic lava flows that are interspersed throughout New Mexico's Valley of Fire. It seems that predators have weeded out light colored mice in this...

By having scholars tackle this interdisciplinary activity, they'll see how social studies and environmental science are related as they explore the impact that the construction of a dam will have on the population and ecosystem of...

Young botanists examine the different parts of tress and then draw parallels between the functions of these parts and the function of parts of the human body. 

Rotating through five stations, evolutionary biologists explore the question of how changes in DNA facilitate the changes in a population over time. High-quality, colorful cards of animals, skeletons, skulls, and DNA sequences can all be...

After watching an engaging 13-minute video about the colorless blood of icefish, future ichthyologists examine icefish blood and non-icefish blood (blood samples are simulated with Karo syrup mixtures) to determine advantages of...

Water is essential for life—and understanding the importance of clean drinking water is essential in understanding sustainability! Show your environmental science class the basics of water testing and treatment through a week-long...

How much time does it take to jump over three balloons? Pupils calculate the speed of tasks that require different motions. They determine motions for tasks such as walking, skipping, hopping, and jumping before creating a...

Areas that previously included no risk of Lyme disease now have cases every year. Scholars learn about the spread of Lyme disease and the relationship with ecological succession. Then, they discuss possible solutions using the known food...

Humans are quickly depleting Earth's fossil fuels and locating them is becoming increasingly difficult! Layered muffins are used for models as young geologists take core samples in order to determine the presence of oil. Consider first...

Nanofibers can be made through electrospinning or force spinning in order to reduce the negative impact on the environment. Pupils study the role of fibers and dye on the environment through a series of five hands-on activities. Then,...

Sickle cell disease only occurs when both parents contribute the trait, and mostly in those of African descent. Where did it come from? How did it evolve? Tony Allison, a molecular biologist, noticed a connection between sickle cell and...

Does the human body evolve as quickly as human culture? With a stellar 15-minute video, explore the trait of lactose intolerance. Only about 1/3 of human adults seem to still have the enzyme lactase and therefore, the ability to digest...

Trying to plan an engaging elementary science unit on natural resources? Conserve your energy! This five-part series of lessons and hands-on activities has exactly what you need to teach young scholars about the importance of conservation.

Encourage peer collaboration and assist with the creation of visual aids to identify carbon, water, and nitrogen cycles as your class learns more about nature. They discuss relative information, create a visual aid...

Prompt scholars to discover the expansion of the universe themselves. Using photographs of other galaxies, they measure and then graph the size and distance of each. Finally, they draw conclusions and prove the universe is...

Darwin explained the connection between species of finches 150 years before scientists understood DNA. Technology and progressing science proved he was right, yet many struggle to understand how natural selection happens. Scholars use...

As the great and hilarious Tim Minchin once said, "Science is simply the word we use to describe a method of organizing our curiosity." Science is more than just a guess; it is based on questions, observations, and evidence. High...

Find out if your class agrees with Ice Age: Continental Drift ... or if it's just a fun family movie! Class members research the theory of continental drift, examine evidence of plate tectonics, connect...

What does the future of energy look like? Junior engineers collaborate to discover a solution to the global energy crisis during a very hands-on lesson. The unit focuses on learning through collaboration to develop a deep understanding...

Two scientists, two independent studies, two similar theories! A video lesson presents the work of Charles Darwin and Alfred Wallace that led to their theories on evolution. Scholars then evaluate statements and provide evidence to...

In 150 BC, Seleucus of Seleucia theorized that the moon causes the tides. Scholars learn about what causes tides by studying the interactions of gravity between the sun, moon, and Earth. They use technology to formalize otherwise...

Some of the CO2 emitted by burning fossil fuels is removed from the atmosphere by natural sinks, such as the ocean. The fifth engaging lesson in the series of 21 examines the CO2 data from three very different locations. It then makes a...

Should every school have solar panels? The 19th lesson in a series of 21 has scholars research the feasibility of using solar panels at their school. They begin by gathering data on the solar energy in the area before estimating the...
