Students in Mr. Melter’s fourth grade science class at Otis are getting “brighter” every day. Electricity is one of the
standards that has returned to fourth grade in the last two years. Students learn a variety of concepts around the idea
Some of those concepts are heat, conductors, insulators, and magnetism. Students have been having fun learning about
these ideas by doing different activities and learning about different ways some of these ideas are used in real life.
Students were given a battery and holder, a light bulb and holder, two wires and given the instructions “see if you can
make the light, light”. After a few minutes of trying every group was able to make the light, light! Over the next week
or two we will stretch that idea into learning about parallel circuits (like Christmas lights).
We have looked at magnets and how there is a north pole and south pole and, for magnets to attract, they need to be opposites.
We have looked at what happens when the poles push away from each other as well. We discussed how some roller coasters that
launch fast do that by using electromagnets. Mr. Melter demonstrated this, on a very slow scale, by moving two magnets around
a table without touching them.
Students have been finding many of these ideas very interesting, and so does Mr. Melter. Since electricity is such an integral
part of all of our lives, it has been fun learning about it. If you have a fourth grade student, please ask them about what
they have been learning and how it applies to all of our lives.
