High schoolers use videoconferences to consult with a professional mentor as they work on a project or experiment in their science class. They evaluate the mentor experience through a written reflection. Students are assessed based on...

To wrap up your year of general chemistry, have lab groups compete in a tot wire chemical vapor deposition (HWCVD) competition. With their foundation in chemical nomenclature, stoichiometry, and gas laws, each group completes several...

General chemistry class members engage in a mini-unit on mole conversions. Through nine lab activites with varying degrees of difficulty, they practice measuring mass and volume, molar calculations, and stoichiometry. Terrific...

High schoolers examine the relationship between inflation and money. Defining key terms, they define money in terms of its functions and give examples of money. They discover what happens when inflation occurs unexpectedly. They also...

Students solve problems of dilation and velocity. In this geometry lesson, students apply the Pythagorean Theorem to solve problems and relate it to time and velocity.

Students measure using the metric system. For this geometry lesson, students solve problems using grams, meters and liters. They convert between the US units of measurements and the Metric System.

Students solve problems using the Pythagorean Theorem. In this geometry activity, students identify the Pythagorean Triple and use it to solve real life problems.

Engineering design projects serve as great opportunities for collaborative problem solving. In this case, students work in small groups designing, building, and eventually testing a structure that meets a teacher-specified objective. It...

Students investigate the volume of cones. In this geometry lesson, students define the formula to find the volume of cones. They define the concept of having to dissect a three dimensional figure and find the volume.

Students design and construct an experiment that will be launched into space aboard a NASA research shuttle. How better to gain and appreciation for (and, hopefully, a love of) scientific investigation than to do real science and be...

Students engage in a lesson which demonstrates that volcanism is the process whereby materials formed inside the Earth come out onto the surface. They participate in a simple, yet effective, activity which demonstrates how volcanoes...

Students determine how diseases are spread from one person to another. They investigate the importance of hand washing to reduce the spread of common colds and other diseases. They listen to teacher read alouds and complete an inquiry...

Students calculate the distance between two points using the distance formula. In this geometry lesson, students derive the distance formula using the Pythagorean Theorem.

Student imitate mapping the ocean floor using the basic concepts of radar. Then they explain what radar is and how it workds. All of their measurements are recorded on a data sheet. Then the data is entered into a spreadsheet program. A...

Young scholars investigate the relationship between angles and their sides. In this geometry activity, students prove why SSA does not work as a true angle side relationship theorem.

Students extract DNA and test for its presence from unroasted (raw) wheat germ using a prescribed procedure. They modify the procedure to provide a less expensive, easier method. They also extract DNA from different available plant,...

Students investigate the childhood of one of the greatest philosophers of our time, Gandhi.  In this biography lesson, students analyze the upbringing and events that finally shaped Mahatma Gandhi's life.  Students locate...

Students solve one step linear equations. For this algebra lesson, students manipulate their variables and numbers to answer each problem. They make sure the equations stay balanced at all times.

Students identify the slope of linear functions. In this slope lesson, students collect data and graph it. They write equations with no more than two variables and use technology to explain their data.

Students collect and analyze data using  percent difference. In this algebra lesson, students relate the concepts of algebra to cardiac physiology.

Young scholars convert degrees between two different units. For this algebra lesson, students graph linear equations and identify the line of best fit. They use their line of best fit to make predictions given a set of data.

Students solve problems by finding the perimeter and area of an enclosed area. In this geometry lesson, students differentiate between the area and the perimeter. They see how they relate and how to use it to maximize an enclosed area.

Students relate Pi to a circle. In this circles lesson, students identify the different properties of two dimensional objects. They relate Pi to the circumference, diameter and area of a circle .

Students apply the concepts of an event occurring to playing a game. In this probability lesson,students differentiate between experimental and theoretical probability.
