Bone up on bone density. The second installment of the seven-part series has pupils read articles on two different websites to learn about bone density and its measurement, as well as X-rays and other imaging tools. A quiz assesses their...

Objects may be more linear than they appear. Scholars investigate the relationship between the number of bone mineral density scanners in the US and time. Once they take the natural logarithm of the number of scanners, a linear...

Hop into a resource on Beer's Law. A PowerPoint presentation introduces Beer's law as part of calculating bone density from X-ray images in the sixth lesson in the series of seven. Individuals work on practice problems with this law and...

Let there be light. The last installment of a seven-part series has pupils conduct an experiment on light attenuation through different numbers of transparency sheets. They then relate the results back to how X-rays measure bone density.

Can you see your class working on spatial visualization? The first installment of a five-part module introduces the concept of spatial visualization and provides a 12-question diagnostic assessment to test spatial visualization skills....

Many people know that fiber optics are used in delivering the Internet, but are surprised to learn they are also used in astronomy. Scholars explore light, reflection, and fiber optics through hands-on activities. They discuss...

Bert the Turtle models for viewers the 1950s Civil Defense Duck and Cover strategy that was supposed to protect citizens from a nuclear blast. After viewing the video, watchers are asked to consider the motivations of the producers of...

Imagine precisely cutting and then moving a 120 ton boulder more than two miles without mechanical cutting tolls, skid loaders, or hydraulic cranes. Imagine carving a stone figure that includes a drainage system that permits rainwater to...

How gets breast cancer? What are the hereditary risk factors? Can individuals reduce their risk factors? If you are looking for a resource to use during October's in Breast Cancer Awareness Month, check out the lessons in this packet.

Take a moment in your language or social studies class to review key terms and details from Narrative of the Life of Frederick Douglass. A quick crossword puzzle allows learners to check understanding before a larger unit, test, or...

Sometimes the hardest thing about an argument essay writing assignment is coming up with a question. A four-page list of prompts includes a range of topics, from social media and smart phones to video games and sports. The list is a...

How efficient is a motor in a LEGO set? Future engineers conduct an activity where a LEGO motor-generator system raises an object to a specified height. They then show what they learned and use their measurements to calculate the energy...

Here's your chance to save the world. The eighth lesson in a 25-part Energy Systems and Solutions unit has young scientists come up with ideas for individual or group projects. They identify ways to solve the energy crisis. Hope they...

Don't drop the ball on the resource ... drop an egg instead! A teacher-led demonstration has the class consider how to drop eggs into glasses when a tray is in the way. Hint: If you've ever seen a magician pull a tablecloth off a table,...

Extra, extra, read all about it! Scholars research information on endangered species and produce a news report to share their findings with the rest of the class. In groups, they then consider engineering solutions to problems on habitat...

When your parents say that your room's a pig sty, tell them about biomimicry. The sixth installment of a nine-part Life Science unit has scholars research the shelters used by animals in the natural world, like turtle shells. Using the...

Let nature guide your engineering designs. By taking apart a flower, pupils learn about reverse engineering. They use the results to brainstorm designs for new products or ideas. This is the seventh installment of a nine-part Life...

Everything can be reduced to atoms. The first installment of a six-part Mixtures and Solutions unit focuses on the building blocks of matter. Scholars review basic atomic structure, including protons, neutrons, and electrons, in...

Do you separate your trail mix before eating it? Then you've been separating mixtures your whole life! Scholars model a contaminated soil sample using trail mix and estimate the percentage of each component. They consider how to clean up...
