Students explain the basic functions of the various economic systems. As a class, they identify the main characteristics of capitalism and the advantages of division of labor and specialization. They describe the relationship between...

Students review the structure and function of DNA, genes, and chromosomes and are engaged by a demonstration illustrating the relative size of DNA, genes and chromosomes. They also describe through analogy and model the structure and...

Students investigate the accumulation of drugs in the body. In this algebra lesson, students collect data on drug retention and assimilation. They use their data to predict the behavior and effects of drugs.

In this Riemann sums worksheet, students use accumulation to find the estimate for the area of a given shape. Students use Riemann sums to estimate the area under the curves and error stacks to bound the error of their approximation....

Learners discover how coroners use insect life cycles to estimate the time of death in cases. they describe how forensic entomologists combine environmental factors with insect life cycles to note the changes. Students examine an...

In this Riemann Sums worksheet, students use the Riemann Sums method to approximate the area under the curves. This two-page worksheet contains three problems.

Young scholars solve problems involving exponential, logarithmic, and scientific notations. Using calculators, students explore investment problems. They use a formula and logarithms to determine the years to earn a particular income,...

Students investigate the fundamental theorem of calculus. In this calculus lesson, students derive the fundamental theorem of calculus. They differentiate between the first and second theorem.

Solve problems using the fundamental theorem. In this calculus lesson, students solve problems using theorems and proving theorems. They derive the fundamental theorem as they study it.

Adaptations must be made as environments change. This fabulous presentation features Icelandic icefish, a transparent, scaleless specimen that even has colorless blood. Genetics and adaptations concepts are explored as scientists study...

Discuss the importance of a lead in writing with your upper graders. They examine several examples of leads from literature and practice writing leads for pieces of artwork. They then select a topic from a list and write an introductory...

Junior geologists work through three mini-lessons that familiarize them with the formation and location of fossil fuels. Part one involves reading about petroleum and where it comes from via a thorough set of handouts. A lab activity...

Young water cycle enthusiasts discover the water they have been using has been cycling around the earth for billions of years. Through presentations, learners will understand that water has three states and how these forms...

The concept of a how pesticides and other chemicals pass through a watershed can be difficult for younger learners to grasp without a concrete example. In the activity here, some blank paper, markers, and a spray bottle are all you need...

Everything evolved from a common ancestor, but how did modern plants and animals develop so many more genes? Scholars use an online interactive to learn about the process. They begin to understand common genes with an animation, multiple...

Students plot earthquakes on a map. In this lesson on earthquakes, students will explore recent earthquake activity in California and Nevada. Students will plot fault lines and earthquake occurrences on a map.

Just because we can't see it doesn't mean it isn't there! A growing concern for environmental scientists is toxic nanoparticles in our air and water. Young scholars conduct an experiment to demonstrate how these particles can cross our...

Explore the difficulties in compiling an oral history with this lesson. Young researchers conduct interviews and consider how point of view changes various accounts of a single incidence, resulting in conflicting information. They view a...

Students solve the mystery of dead Mr. Potato Head using physics and algebra. They discuss Newton's Law of cooling as it applies to the mystery scenario involving a cooling baked potato as the "victim". They manipulate algebraic...

In this asteroids and planets worksheet, students read about the formation of planets from asteroids. Students solve 6 mathematical problems including finding the rate of growth of a planet, determining the mass of a planet at a given...

In this Deviance: Functionalist Explanations worksheet, students read five pages, then complete several exercises including creating prompt cards, labeling actions appropriately, and deciding what are strengths or weaknesses of theories.

Learners explore DNA microarrays. In this genetics instructional activity, students model DNA microarrays that are used by scientists. Learners work to determine levels of breast cancer genes in patients. They will determine the...
