In this experiment, students measure the area of a dime using methods similar to those used by scientists to measure the size of atoms. When working with atoms, scientists sometimes have to invent new ways of doing simple things. For instance, scientists can't use a ruler to measure the size of an atom's nucleus. This activity shows how ratios can be used to calculate the area covered by an object.

This math problem determines the areas of simple and complex planar figures using measurement of mass and proportional constructs. Materials are inexpensive or easily found (poster board, scissors, ruler, sharp pencil, right angle), but also requires use of an analytical balance (suggestions are provided for working with less precise weighing tools). This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

Experimenting with STEM: The Barbie Bungee Jump
Rating

Eighth grade teacher Patrick Roda has students apply their knowledge of the line of best fit to design successful bungee jumps. He tells students that they will test their bungee jumps in the stairwell, with the goal of getting Barbie as close to the ground as possible without touching the bottom step. Patrick has his students begin by constructing a bungee with two rubber bands, attaching a Barbie, and measuring how far the Barbie falls. Students add more rubber bands, perform multiple trials, and record their results in a table. Using their collected data, students construct a scatter plot and determine an equation for the line of best fit. After making predictions about the performance of their bungee jumps, the students test their bungee jumps and discuss their results as a class.

In this measurement lesson plan students use their estimation and reasoning skills to develop benchmarks for an ounce and a pound. Students test the accuracy of their estimates using a scale and give themselves a score based on how close they came to the desired weight (an ounce or a pound). This lesson plan includes a student data collection worksheet (PDF).

This lesson fosters a student's conceptual fraction sense with proper fractions, improper fractions, and mixed numbers by placing thirty fraction cards in order between given whole numbers on a number line clothesline. Users will visually identify that all proper fractions are grouped between zero and one, and that improper fractions or mixed numbers are all grouped above one. Users also play an estimation game with groups using the same principle. Instructional plan, questions for the students, assessment options, extensions, and teacher reflections are given.

In this five lesson unit with overview from Illuminations, student activities explore relationships among fractions through work with the length model. Students construct fraction strips and use fraction bars throughout the unit to make sense of basic fraction concepts, to compare fractions and order fractions and to work with equivalency in fractions. Specific learning objectives, a material list, an instructional plan, questions for the students, assessment options, extensions, and teacher reflections are given for each lesson.

This interactive lesson encourages young students to solve problems by estimating angles and distances. They use an applet to give LOGO-like commands, e.g. forward (length), turn (right or left) to make a path that moves a turtle to a pond. Students can create a Path 1 and Path 2 and try to minimize the total path length. There is a newer applet (Turtle Pond, cataloged separately) that allows for adding or editing the commands and a choice of right angles only, or angles in multiples of 15 degrees. The lesson provides suggestions for implementation and discussion questions.

Estimates of global health indicators - which give insight into death and disease rates, document advances in development, and help policymakers monitor progress - are absolutely essential for improving global health. Estimates, however, are always imperfect and are sometimes fiercely debated. Recently, new players from academia have entered the game of global health estimation, once the chief domain of United Nations agencies such as WHO. In November 2010, PLOS Medicine published a collection articles from a series of experts that provide insights and opinion on what estimates mean for global health and how to move forward with better data, measurement, coordination, and leadership. The collection includes the perspectives of WHO, the Institute for Health Metrics and Evaluation, and stakeholders from low- and middle-income countries.
