Youngsters make a mental assessment of electricity-consuming appliances in their homes and then evaluate them for the amount of energy consumed. They learn how to use power meters and measure the electrical consumption of several...

True or false — Double Stuf Oreos always contain twice as much cream as regular Oreos. Scholars first measure the masses of the filling in regular Oreos and Double Stuf Oreos to generate a class set of data. They use hypothesis testing...

It's time for scholars to show what they know about coordinate planes with a collection of three assessments. The exams' objectives include plotting points on a single grid, measuring using the distance formula, and identifying...

Seven activities make up a collection of supplemental materials to reinforce graphing on a coordinate plane. Worksheet objectives include plotting coordinates within single and four quadrants, measuring straight and...

Viewers learn about three different weather measurement tools in installment five of the 10-part Discover Your Changing World series. They build weather vanes to collect data on wind speed, barometers to determine air pressure, and...

Polygon ... an empty bird cage? After finding the angles of a polygon, young mathematicians use the provided methods to solve the problem in multiple ways.

Young analysts use real (provided) data from a class's test scores to practice using statistical tools. Not only do learners calculate measures of center and spread (including mean, median, deviation, and IQ range), but...

See how design and geometry go hand in hand. The activity asks learners to use geometry to design a backyard garden given dimensions of each feature. Scholars work with ratios and scale to develop an accurate scale drawing that includes...

How are chemical reactions affected by gravity? Learners explore the phenomenon of effervescence as part of the Christa's Lost Lessons series. They compare findings in an experiment on effervescence to a video of a similar experiment in...

Searching for a detailed instructional activity to assist in describing rotations while keeping the class attentive? Individuals manipulate rotations in this application-based instructional activity depending on each parameter. They...

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.

Moooove over, there's a better deal over there! The fourth segment in a series of eight requires individuals to determine the best unit cost for milk. Scholars calculate the least amount they can spend on a particular quantity of...

What properties does area possess? Solidify the area properties that pupils learned in previous years. Groups investigate the five properties using four problems, which then provide the basis for a class discussion.

There are several instruments that can be used to measure the pressure of a gas. Here, junior chemists venture into the workings of a manometer. Barometers the Boltzmann Distribution are also detailed. A highlight of this presentation is...

Students examine how navigation is based on mathematics and how making a mistake in measuring an angle could have an impact on a target. They observe a teacher-led lecture, use a calculator to complete two worksheets, and participate in...

Students experience a positive science experiment and study fundamental concepts of measurement.

Fifth graders find perimeters, areas, and volumes of everyday objects and state the precision. They work in small groups in order to take measurements, perform calculations, and write a group report about the investigation.

Students complete a number of practical measuring investigations, with an emphasis on accuracy of measuring and communication of their findings. They examine how to measure by first becoming aware of the physical attributes of objects...

Upper graders practice their estimation skills by observing different objects then making their best guess without using measuring instruments. Students are asked to estimate mass, length, volume, and area.

Compare different random sampling types using an archaeological setting. Scholars collect data from an archaeological plot using simple random samples, stratified random samples, systematic random samples, and cluster random samples....

Sew up pupil interest with an engaging, hands-on lesson plan. Learners first design a sports bag given constraints on the dimensions of fabric. They then evaluate provided sample responses to identify strengths and weaknesses of included...

Sixth graders sketch their own kites by creating a scale drawing of an original design.  In this designing kites instructional activity, 6th graders draw a rough sketch, then accurately draw their design on large paper with a ruler,...

Students construct a weather vane using their knowledge of some geometric shapes. In this weather lesson, students work in pairs to create a weather vane in order to measure wind direction. Students follow precise...

This discovery student page offers students an opportunity to work as a team to discover the shape of an object they cannot see. It is an experiment which parallels particle physicists dilemma in not being able to see very small...
