Play these fun games to learn about measuring an comparing. Click and drag on the animals to put them in order. Do biggest to smallest first and then do smallest to biggest.
The students will measure the surface area and wrapper area of five pieces of candy. They will use appropriate formulas and measuring techniques to complete information needed for a spreadsheet and database. They will write a letter to the company with the most wasted paper to explain how the waste affects them as consumers and a suggestion for correcting the problem.
Students will use tangrams to compose and decompose shapes.
In this activity students learn about the natural phenomena that create a total eclipse. Students also explore the history, mythology, science, and math that relate to these amazing events. NASA scientists and engineers introduce a satellite where scientists make artificial eclipses in order to learn more about the Sun's corona. Using hands-on lessons, web-based activities and simple tools, students will measure the angular size and predict the angular distance of objects in the sky. Grades 6-8.
The Online Science-athon offers elementary and middle-grade students opportunities to discover the science in their daily lives. Presented as challenges, the Science-athon asks students to investigate their world in ways that are engaging and fun, easy for teachers to incorporate into their teaching, and instructive. Students participating in How Tall Am I? create a way to measure their height as accurately as possible. On Measuring Day students collect and record data and share it with other students doing the challenge. Display and analysis of the data in the challenge database allow them to see if the larger data set supports their conjectures and predictions.
This exercise illustrates the techniques for macerating wood and staining, mounting, and measuring tracheids. Mean tracheid length is different in different species of conifers; therefore, this laboratory can be expanded into a larger scale comparative measurement exercise.
