Students Use Simple Machines

Fourth-grade students are learning about simple machines in science class and recently put some of their knowledge to use in an experiment with the help of district science consultant Claire Zurbuch.

Using a lever, wedge and weight, students were able to find an object’s mechanical advantage. To do so, they had to first divide the effort distance by the load distance. The effort distance is how far the load, or weight, is from the pivot point, which was where the wooden lever was bolted to the PVC pipe. There were five points on the wooden lever, all 10 centimeters apart. The load distance was how far the weight was from the pivot point.

Once students got the necessary information, Mr. Z had them move pivot points, holding points and weight to determine the mechanical advantage of the various spots. Students found that the higher the mechanical advantage number is, the easier it is to do the work, which in essence meant that the closer the weight was to the pivot, the easier it was to lift. The students did great work; it was a complex lab. Thanks, as always, to Mr. Z for providing great information and hands on experience for the students to better understand a complicated subject.

Summer School Applications

Cardinal Schools is providing online summer school classes to students in need of credit recovery. Classes are available to students in any district.

Summer school is offered using FuelEd, which is an online platform for course delivery. Students must have access to a computer and internet.

Cost to enroll in core classes is $200 and health and physical education are $175.

Sign-ups can be completed on the district website www.cardinalschools.org or by filling out an enrollment form in the Board of Education Office by June 4.
