By mounting a light bulb on a stand and a PV cell on another, physics apprentices experiment with the angle of incidence. Their goal is to determine the optimum angle for collecting solar energy. The use of a scientific calculator...

In this geometry instructional activity, learners create circle, line and bar graphs using different comparisons of events. There are 24 questions with an answer key.

Focus on the Latin roots struct and tract with this PowerPoint, boasting plenty of practice opportunities. To help develop a definition of each root, viewers match a list of words to their pictures. Then, they compare those words to a...

Is that drawn to scale? Capture the artistry of geometry using the ratio method to create dilations. Mathematicians use a center and ratio to create a scaled drawing. They then use a ruler and protractor to verify measurements. 

Life science learners discover the range of peripheral vision. They compare the angles at which they can detect motion, colors, and detailed shapes. 

Young scientists build on their previous knowledge and apply it to coronal mass ejections. By plotting the path of two different coronal mass ejections, they develop an understanding of why most don't collide with Earth.

Explore the behavior of light with different materials. Collaborative groups determine whether certain materials absorb, reflect, diffract, or transmit light waves. They then measure the angle of incidence and angle of reflection.

Young classes are sure to get a charge out of this lesson plan! Learners experiment with circuits of a solar cell. They practice determining current, voltage, and power for the circuit and maximize the voltage and current of the cell.

Allow your pupils to become the mathematicians! Individuals explore the properties of a midsegment of a triangle through construction and measurement. Once they figure out the properties, learners use them to draw conclusions.

Students solve and verify the solution for unknown measures. In this geometry activity, students identify the properties of circles. They use the arc, angle and segment relationship to find the missing measures.

Exact narrative and examples make this lesson on polygons easy to implement. Through it, your class will learn how to use a protractor and ruler to construct triangles and quadrilaterals according to your directions. Your class will be...

Students find the altitude of the Sun at 10 A.M., at solar noon, and at 2 P.M. by measuring the height of the gnomon and the length of the shadow at each time. They record the measurements in their notebooks for later conversion.

Young scholars study the history of kites and their fundamental properties.  In this kites lesson students divide into teams and build and fly kites. 

Students practice using a protractor and ruler to draw various points and lines. Using a computer, they draw the points and lines in the program and describe the differences between their drawing and the computer's drawing. They complete...

Eighth graders use a meter stick that is placed on a horizontal surface and an object is moved along it so that the shadow length can be measured at different distances from the light source. They solve real-world problems involving...

Students conduct an experiment and use different measurements of a single root to illustrate the mechanism of plant movement.

Young scholars conduct an experiment in order to observe the typical downward growth of a maize root. They become familiar with the root's growth patterns to use as a control for comparison in other experiments.

Young scholars explore how to solve any quadratic equation with a video about the quadratic formula. They then use the quadratic formula to solve a set of quadratic equations.

Students utilize triangulation techniques to determine altitudes of objects. An altitude locator is constructed and used to determine the height of a building or a tree. Tangent tables and formulas provide the ratio for the formula to...

In this designing a periscope worksheet, learners follow the directions to collect materials and make a periscope. Students answer 5 questions.

Students examine the external variables that affect a downhill skier in the quest for speed. They access websites imbedded in this plan to become ski teams competing against one another. Each team presents results of all experiments.

Students use the human body as a foundation for gaining practice in measuring angles and calculating ratios and proportions.

Fifth graders engage in a variety of hands-on and technology-rich activities involving the classification of quadrilaterals. They utilize protractors and rulers to investigate the characteristics of various types of quadrilaterals. They...
