There's absolutely no error in using the tutorial! Learners use spreadsheets to create column or bar graphs with error bars. They also learn how to calculate the standard error of the mean in the tutorial. This is the third installment...

There are an average of three human fatalities by bears in North America every year, which is low when you compare it to the 26 killed by dogs and the 90 killed by lightning annually. The lesson encourages researching human-bear...

Dead trees provide nutrients for the soil, food for animals, protection and a home for organisms, a seed-bed for new trees, and a place for nitrogen-fixing bacteria to live. In the activity, pupils collect decaying logs, expose them to a...

No one likes kidney stones, but they are very interesting to learn about. The last installment of a three-part unit has learners experiment with different chemicals to see which one inhibits the growth of calcium oxalate crystals (which...

Do you think the lab smells like rotten eggs? Sorry to hear about your sulfering. A set of five experiments covers many different topics including seasons, gravity, food, precipitation, and photosynthesis. Though not presented as a...

The engineering design process meets laparoscopic surgical robots with an activity that is the last part in a series of 10 and brings all the lessons of the unit together. Teams design and build a remotely controlled laparoscopic device....

Class members use an air quality monitor to measure the amount of gas-phase pollutants emitted by different sources. Groups choose three different sources and make predictions about what the monitors will detect. Teams then expose...

See how changes in initial populations and parameters affect a biological community. Individuals use a special software program to simulate a desert community with five species. They adjust initial populations to see how the community...

Introduce the concept of exponential functions with an activity that extends the definition of exponents to include rational values. Start with a doubling function at integer values of time, then expand table to include frational time...

Biology or health nuts select a disease to research and produce a pamphlet that can be used to inform the public. The tri-fold product is worth 100 points according to the included grading page.

Waterton-Glacier International Peace Park includes whitebark pines that are over 1,200 years old, meaning they have been there since before medieval times. The second lesson of five details how to read tree rings for climate change and...

Your entire class works together to create an illustrated insect field guide. The intent is that they venture outside of the classroom, find a critter, and then research it using reference materials, insect books, and the Internet for...

Sometimes it's okay to eat your science experiment. A hands-on activity has pupils create models for algae to learn about its cellular structure. The best part of the experiment? The resulting juice-filled gels are edible—yum!

Taboo, anyone?! A vocabulary review lesson asks learners to give their partners clues to help them guess the target word. The catch? There are words that are taboo. If they use the prohibited words, they don't get credit if partners...

Interestingly enough, movement is not a characteristic of living things. The first activity in a series of 20 introduces learners to the concepts of living versus non-living things and then focuses on biologists and what they study....

Human impacts on the environment can sometimes be difficult to measure, especially under water! An activity centered on ocean acidification gives science scholars the opportunity to examine the effects of carbon dioxide on marine life....

For as small as they are, plankton sure play an enormous role in maintaining marine ecosystems. Dive into an investigation of these tiny organisms with a hands-on life science activity in which children cut out pictures of sea...

Investigating the large numbers of science is the task in a simple but deep activity. Given a one-sentence problem set-up and some basic assumptions, the class sets off on an open-ended investigation that really gives some...

Cells of different organs have unique cell functions. Learn how cell functions vary depending on their roles in the body using an inquiry-based activity. Scholars analyze the cell structure to make comparisons to its functions, allowing...

The Clark's nutcracker bird hides seeds in 25,000 different sites every year to save for winter. Lesson demonstrates how difficult it would be to find these seeds months later when they need them for food. In the first of five lesson,...
