Pupils examine the centroid of a triangle as they use Cabri Jr. to construct a triangle and its medians. The dynamic nature of the software allows learners to measure the lengths of the segments in the triangle and conjecture and verify...

Pupils explore the midsegment of a triangle in the geometry lesson. They draw and measure the segment joining the midpoints of the two sides of a triangle and compare its length to the length of the third side of the triangle. The...

Students explore density, mixture and solutions in a reaction. In this chemistry lesson plan, students create their own chap-stick using ingredients they analyze for their chemical contents. They discuss measuring skills, melting points...

Students move through a variety of locomotor skills at different paces to see how they affect their heart rate. In this health, human body, and physical activity lesson plan, students measure their heart rate and discuss health. A...

This lesson enables students to explore and measure the distance between blacks and whites in the past and present United States. By thinking about the intersections of whites, blacks, and others around the blues, students will deepen...

In this gas worksheet, students use the ideal gas law to find volumes of gases, pressure of gases, moles of gases, mass of gases and molecules of gases. They find unknowns at standard temperature and pressure and they calculate the...

Students observe how math is important in navigation and engineering. They study how surveyors use math and science to calcute, count, measure, label, and indicate distances on a map. They estimate specific distances.

Fifth graders study dehydration and dehydration of foods. They measure the amount of water lost from fruits as they are dehydrated. They use desktop publishing software to design an advertisement for dehydrated fruit after researching...

High schoolers engage in a lesson that is about the concept of measuring the statistical data of a population taken from a census. The data is interpreted and recorded looking for trends in subjects like world economy and job opportunities.

Students investigate the concept of how earthquakes occur and the after effects of how they effect landforms. They conduct research it using a variety of resources and measure the varying intensities of how earthquakes effect the...

In this three- and two- dimensional geometry worksheet, 7th graders solve 12 various problems related to geometric shapes and measurement. They first use paper and a pencil to sketch the front, side, back, top and bottom views of each...

Students draw perpendicular bisectors.  In this perpendicular bisectors lesson, students identify the perpendicular bisector in a polygon.  They use web tools to create and measure perpendicular bisectors.  Students...

As an introductory activity, young statisticians measure their heart rate at rest and after exercise and compute the mean and median, and create a box & whisker plot.  This is followed by watching a video (that no longer seems...

Learners parcticipate in a modeling activity that simulates the cyclical role of experimental and theoretical science. Initially, students measure the mass of popcorn. They also record predictions of the mass of the kernels after they...

Eighth graders engage in hands-on activities to determine the surface areas of various objects. Using boxes, they cut them so they can lay flat and measure all the various shapes, which can be calculated and added together to equal the...

Young scholars demonstrate problem solving skills. Students complete word problems requiring unit conversions. They convert both metric and standard units. Young scholars must determine necessary information to solve problems.

Students investigate the concepts of area and perimeter with the use of chocolate bars. They calculate the perimeter and area of different size rectangle chocolate bars and record the statistics. Then students make a visual comparison...

You can eat a solar cell? A unit on solar energy begins with a discussion about organic solar cells, followed by directions on how to build your own. After following the teacher's directions to build an anthocyanin...

How high did the ball go? Engineering teams build a working pneumatic system that launches a ball into the air. The teams vary the amount of pressure and determine the accompanying height of the ball. An extension of building a device to...

Just how big would it really be? Young mathematicians determine if different toys are proportional and if their scale is accurate. They solve problems relating scale along with volume and surface area using manipulatives. The...

What does math have to do with a sore throat? When you mix water and salt you have a great review of how to represent proportional relationships by an equation or graph. Here the proportions of the mixtures may be different, but the...

This demonstration of solar ponds can be used in an earth, environmental, or physical science setting. Lab groups set up a solar pond and model how it is able, due to a salt concentration gradient, to maintain heat for future use. 

Students investigate the area and circumference of a circle. In this geometry lesson plan, students estimate and measure the radius, diameter and circumference of a circle. This assignment has an online part that is interactive.

Students explain necessity in using accurate instruments when measuring, and how measurements can be checked for accuracy. They make a six-inch ruler, design, test, and evaluate a system to measure work, and produce a table and graph to...
