How is the magnitude of an earthquake measured? How is the intensity of an earthquake measured? What is amplitude in relation to an earthquake? In what country was the largest magnitude earthquake? There is a wealth of information about earthquakes and your learners will definitely want to use their calculators to figure out the answer to some of the questions. It might take more than one class period to cover all the material.
Students investigate the importance of accurate measurements. In this sixth through eighth grade geometry lesson, students view Measure for Measure: Lengths and Heights as they explore the history of measurement. Students use their own feet as a standard measure and then measure and compare distances.
What measurements are shown on these rulers? Learners read eight rulers and record the indicated lengths in centimeters. There are no fraction answers. Remind kids to write the units into the measurements. Extend this by assigning scholars one of the worksheet measurements and giving them each a ruler. Can they find something in the classroom with the same length?
In this exploring measurement worksheet, students measure the perimeter of several listed objects. Students then estimate how many times they would have to measure those perimeters to make 1 mile. Students respond to 4 short answer questions and use a leaf measure grid to find the area of several leaves.
Second graders review measurements in inches and practice measuring different objects. As a class, they estimate various objects in their classroom and compare their estimation to the actual measurement. To end the lesson, they complete a journal with their measurements for future use.
Students discover the ratio between arc length and radius. In this ratio between arc length and radius lesson, students use the Ti-Nspire to determine how arc length and radius are related. Students determine the arc length measure in radians. Students use the arcLen command on the Ti-Nspire to find the arc length measure in radians.
First graders explore the scientific method. Given the opportunity to perform several hands-on experiments, learners follow directions to practice the methods of the scientific inquiry. They predict the outcome of each experiment and discuss the final results. Finally, in small groups, classmates explain why procedures for an experiment will give the same result if performed multiple times. Students may use technology to graph results of experiments.
Learners examine three seismograms of a recent South American earthquake recorded by USGS stations. They measure the S-P distance and use a P and S wave travel-time graph to find the epicenter distance for each seismogram. In addition, they use distance to find the epicenter of the earthquake.
Students tell time in this instructional activity using analog and digital clocks, as well as finding elapsed time. Students explore the importance of scheduling and time management. Students complete the instructional activity by individually completing an activity to find elapsed time.
Learners investigate the effects of time and distance for the creation of a successful railroad. In this railroad lesson plan, students recognize the railroad's need for an exact time schedule was the cause for the creation of time zones. Learners answer questions about the need for exact time. Students create a water clock.
In this angle lesson, eighth and ninth graders explore angles made using parallel lines and a transversal. They identify the types of angles and the characteristics of each one. Puils create drawings that illustrate angle relationships in real world situations, and determine the measures of angles.
Upper graders work with peers to solve word problems related to time and independently solve word problems that involve calculating time. They will show their ability to solve and work through mathematical operations. A worksheet is provided in addition to a well-written teacher's guide.
Young economists will enjoy this approachable and informative presentation. It is full of helpful graphs and definitions. Especially interesting will be the graph that measures the global perspective of the underground economy as a percent of GDP, as well as a discussion about an expenditures approach versus an income approach to economics.
Elementary schoolers practice measuring elapsed time between events. Learners work together to complete a worksheet, embedded in the plan, on elapsed time. The puzzle they must solve takes some time to complete. One of the tasks each group has is to keep track of the time that elapses while they are solving the puzzle! This lesson is based on the popular Cyberchase television show. A very good activity!
Ninth graders use, describe, and apply the relationships between dimensions of geometric figures to solve a variety of problems using indirect measurements and apply rate and scale. They observe the teacher modeling examples of each type of problem, and independently complete a worksheet.
