Bring the learning outdoors with an enjoyable activity about Earth's heating, sunlight, and shade. Scholars use problem-solving skills as they design, build, and test a sunshade structure. Participants view a video summarizing the...

Examine the consequences of varying speed.  An engaging set of five problem sets challenges young mathematicians by targeting a different grade level from K-12. In the initial lesson, scholars make conclusions about the time it...

Number towers use addition or multiplication to ensure each level is equal. While this is common in factoring, it is often not used with algebraic equations. Solving these six questions relies on problem solving skills and being able to...

Do pilots create appropriate spacing between aircraft by traveling a longer or shorter path? An interactive presents two airplanes that violate safety protocols. Pupils must determine how to change the path of one plane to create...

National Chemistry Olympiad tests are released after their use each year, since they cannot use them again for this event. The result: outstanding comprehensive assessment resources for general chemistry classes! This 2005 version covers...

Describing a problem efficiently doesn't solve it, but a well-crafted argument can move readers to action. High schoolers focus on structuring problem statements by reading examples of strong essays and working in groups to create...

A full-fledged practice final prepares pupils for their general chemistry final exam. If they complete these 57 multiple-choice questions correctly, they will be well-prepared. Note: even though the questions are multiple-choice, there...

Linear equations are the focus of activities that ask learners to first complete a task that involves interpreting algebraic expressions and solving linear equations. They then take part in a card activity matching...

Young scholars write and solve linear equations in one variable based on descriptions of the operations that are applied to the unknown variable in an algebra machine. They then create their own problems for classmates to solve.

Active listening is key to interacting with others in a way that shows respect. To develop their skill as listeners, high schoolers first play the "Telephone Game" to demonstrate some of the problems that arise in communication. Pairs...

In this National Olympiad Exam worksheet, students answer sixty multiple choice questions including topics such as atomic structure, problem solving, thermodynamics, acids and bases and solutions.

Students investigate how to create a free standing structure. In this mathematics lesson, small groups of students demonstate how to build the tallest structure while spending the least amount of money on materials.

What does it take to build a stable arch? Pupils apply vectors and physics as they examine arched bridges and their structural integrity. They use vectors to represent the forces acting on the stone sections and make conclusions based on...

Tie the unit together and see concepts click in your young mathematicians' minds. Scholars apply the properties of similar triangles to find heights of objects. They concentrate on the proportions built with known measures and solve to...

Young readers examine the elements of story structure that are included in all stories. They include these elements in their own written pieces. This phenomenally-designed plan has everything you need to easily implement it in your...

How tall is your marshmallow structure? With limited supplies (including uncooked spaghetti noodles, masking tape, and one marshmallow), teams endeavor to support the marshmallow atop the tallest spaghetti structure they can build....

Many problems in life have more than one possible solution, and the same is true for advanced mathematics. Scholars solve seven problems that all have at least two solutions. Then three higher-level thinking questions challenge them to...

Most problems can be solved using more than one method. A worksheet includes just nine questions but many more ways to solve each. Scholars must graph, solve, and justify quadratic problems.

Where did that formula come from? Lead pupils on a journey through completing the square to discover the creation of the quadratic formula. Individuals use the quadratic formula to solve quadratic equations and compare the method to...

Have your class draw the plans and design a structure. Learners discuss and investigate the variables in the stability of a 2D and 3D model. They also consider how to add a circuit to the design. Afterwards, they present their work.

Students investigate what is inside three different boxes using indirect observations and relate it to the discovery of the structure of the atom. For this atomic structure lesson plan, students explore the history of atomic structure by...

In this chemical compounds worksheet, students draw and correct Lewis structure for the given compounds or ions. Students draw the resonance structure if applicable. This worksheet has 8 problems to solve.

Your learners explore growing patterns by describing, extending, creating, and evaluating practical pattern problems in this three-day collaborative unit. Beginning with concrete patterns and function tables to extend and...

Only eight problems are on this competitive national chemistry exam. It required the balancing of chemical equations, solving stoichiometry questions, and more. This is part two of three of the national exam. Also available is a...
