Students complete a unit about the history and geography of the Dominican Republic and the reasons for Dominican immigration to the U.S. in the 1960's. They conduct Internet research, write a biographical sketch of Raphael Trujillo, and...

In this mathematics worksheet, students use this as a resource for looking up conversion tables for mathematical and scientific data.

In this weathering worksheet, students use Alka-Seltzer tablets to simulate the effects of particle size on weathering and they study the effects of temperature on weathering. They answer questions to conclude the activity.

High School geometers verify through experimentation certain properties about dilations. This multi-step problem challenges them to construct examples of dilations to verify specific facts, the final step provides an opportunity to more...

Simplification is about factoring. While working with rational expressions, pupils must know how to factor. The video shows how the process of finding common factors in algebraic fractions is similar to finding common factors in...

What happens to a volume when you scale the dimensions of a rectangular prism? In this problem, a box of clay is increased in each dimension, with the intent to see if learners can generalize the result. The addition of...

Make the complicated look relatively simple. The video shows how multiplication of algebraic fractions is easier when they factor the numerators and denominators. Pupils see which factors will cancel, or divide out, easier when writing...

Exchange rates are dependent on a variety of factors. Scholars tease out these factors using a prompt from College Board. Another query examines the economic health of a country with barometers such as gross domestic product and wages. A...

Multiple factors affect the survival of endangered species. A hands-on activity has learners explore those factors. They play a board game that highlights factors such as human influence, habitat availability, and new species introduction.

Internal and external factors influence behavior and decision making. The third session in a 10-lesson series focusing on Social, Physical, Emotional, Cognitive and Spiritual (SPECS) health explores the impact of these factors...

Collaborative activities teach adolescents to talk comfortably about teen issues. Class members identify eight factors of healthy relationships among friends, family, and boyfriends/girlfriends. These factors are then used to help...

To determine the dimensional change to quadruple the area, class members determine how to increase the dimensions of a square and a circle to increase the perimeter by a given factor. they then calculate the necessary factor to...

There's nothing irrational about this lesson. Explore the process of multiplying rational expressions through discovery. A well-designed lesson has learners factor and multiply rational expressions by dragging factors to the correct...

Scientists can model global surface temperature with and without considering human emissions, but does do these factors really make a difference? Two interactive graphs demonstrate some factors that affect climate change. The first graph...

The sustainability of an ecosystem depends on many factors and changes constantly. Young scholars consider these factors as they use a set of cards to create food webs. They review key scientific vocabulary such as predator, prey,...

Expand and contract algebra. Using a video from a larger review series, pupils refresh their skills to factor algebraic expressions. They also use the distributive property to expand expressions on the learning exercise. Problems range...

How does one factor in the social costs of a product? What factors influence price? Learners consider the question and others using authentic College Board materials. Other questions examine profits and competition in the market and the...

Researchers go beyond the surface of an election issue to craft an objective report on the history of the issue, factors surrounding the issue, and factors in a candidate' biography that may influence a candidate's position on the issue....

Otters swim through numerical gates carrying multiplication equations with a missing factor. By choosing the gate with the correct missing factor, players make the otter swim faster in the online game.

Divide and conquer factoring. Learners see how dividing polynomials is similar to long division of numbers. Pupils learn how to use long division of polynomials to help find factors of higher degree polynomials. They then use their...

Working in groups, sixth-graders identify internal factors that negatively impact them. Then, explain how they could change that factor into a positive influence. Finally, individuals create personal mind maps that identify their...

An eye-opening activity uses documents and photos to help academics understand the factors that pushed or pulled immigrants to America. Young historians group photos based on a push or pull factor, then complete a worksheet. Scholars...

Many factors shape the identity of persons, communities, and even nations. Tweens and teens have an opportunity to consider the many aspects of identity as they create a graphic that reflects who they are. Class members first brainstorm...

Stressed? Stressed high schoolers? Check out a lesson that includes a checklist of causes of stress, suggestions for ways to deal with stress, and a role-play activity. Definitely worth a look.
