Activate middle schoolers' minds with this physical science activity. Learners vary the diameter of gears and the number of teeth on them to find how energy output is affected. This writeup features well-developed background...

Students solve problems using the Pythagorean Theorem. In this geometry lesson,students identify the right angle, hypotenuse and legs of a right triangle. They find the missing sides using the ratios of the Pythagorean theorem.

Students investigate the different properties of trigonometry. In this precalculus lesson, students find the six different identities of trigonometric ratios. They relate the ratios to that of a right triangle and apply it to real life...

Designers measure their own rooms and produce a scale drawing. They use the Internet to visit sites to find the costs of purchasing new carpet, paint, or anything else they would like to add to their room. Using a $1500 budget, they will...

Young scholars treat a high molecular weight polyvinyl alcohol polymer with potassium periodate. They measure the viscosity of polyvinyl alcohols.

Students solve problems with slopes. In this algebra lesson, students identify the slope of a line and relate it to the rate of change.  They graph their lines on the TI and observe changes in the lines.

Middle schoolers experiment with common household products to determine the properties of emulsions and how they fit into the classifications of matter through this series of lessons.

Students solve problems involving ratio and proportion. In this algebra lesson plan, students analyze the currencies found in different countries. They create formulas to convert between the different currencies and use ratio and...

Students calculate the surface area of polygons. In this geometry lesson, students use spacial reasoning to find the answer to their problem. They analyze solids and create formulas to estimate the measurements of the area.

Students determine the length and width of leaf samples to the nearest millimeter and the circumference of trees. They participate in a discussion about the importance of collecting specimens carefully. They compile accurate...

In this radioactivity worksheet, students write the mass number and atomic number for the missing element in the reactions. Students identify the isotope that is more stable and determine the half-life of the isotope. This worksheet has...

Young scholars investigate properties of lines and points by making a rover. In this algebra instructional activity, students plot points correctly on a coordinate plane. They identify coordinate pairs given the plots and lines.

Students bag trees to determine the mass of the water given off in the evapotranspiration process.

Collect and graph data using Microsoft Excel with your math class. They will make predictions about the number of each colored candy in a bag of M&M's, then sort, classify, count, and record the actual data before using Excel to...

If a 150 lb. person can comfortably eat and digest a 1 lb. burger, then how large would the person be who can comfortably eat and digest a 350 lb. burger? For a burger that size, it would take either a large person or a class of really...

A hands-on lesson using the TI-CBR Motion Detector to provide information to graph and analyze. The class uses this information to calculate the slope of motion graphs and differentiate scalar and vector quantities. There is a real-world...

Win the war of the worlds! Scholars solve a variety of problems related to an alien invasion. They determine where spaceships have landed on a coordinate map, devise a plan to avoid the aliens, observe the aliens, and break a code to...

Students measure, analyze, and compare the ancient Egyptian canon of proportions using a mummy, painted images, and photographs of people today.

High schoolers explore the differences between specific soil characteristics. They participate in an experiment in which they discover soil texture. They write their observations in a journal.

Pupils calculate the stride length of a walking or running animal. They use scale models of dinosaurs to calculate the leg and stride length of the animals.

Students explore the concept of similarity and congruence. For this similarity and congruence lesson, students identify and verify whether or not two figures are similar, congruent, or neither. Students use postulates and theorems such...

Students explore the concept of similarity and congruence. In this similarity and congruence lesson, students cut out strips of paper and form a triangle. Students try to prove that their triangles are congruent using the SSS theorem of...

Find the length of an arc. Students relate central angles to the area and length of a sector and graph circles on the TI to make predictions.

Students graph systems of equation. In this calculus lesson, students graph their lines on a TI calculator. They identify the point of intersection and the type of solution.
