31 mar 2021 · In this lesson, we learn about how maps show scale and how we can use these to measure distances. Watch more of our video lessons at http://www.getatomi.com
How-To Steps. Use a ruler to measure the distance between the two places. If the line that you're trying to measure is quite curved, use a string to determine the distance, and then measure the string. Find the scale for the map you're going to use.
How exactly does the strength of a magnet change with distance, and how would you measure it if you wanted to find out? In this project you will build a circuit that can measure the strength of a magnetic field and see how the field strength changes with distance.
How exactly does the strength of a magnet change with distance, and how would you measure it if you wanted to find out? In this project you will build a circuit that can measure the strength of a magnetic field and see how the field strength changes with distance.
By moving a small and known amount towards or away from the magnet, you can calculate the distance to the magnet by how much the field strength changed over the know distance between the two measurements.

25 kwi 2017 · Attraction and repulsion projects are good for fourth graders first beginning to explore magnetism. A magnet has two poles (north and south) and magnets either attract or repulse each other depending on the orientation of the poles.
