Mass vs. Volume
Mass Vs. Volume is inteded to teach the difference between mass and volume. The principle idea being that just because something is bigger than something else, does not necessarily mean it is more massive.
It is recomended that the teacher do the levels in order, and use at least the first three levels. The third level is random, so repeated use with different seeds is possible, perhaps even recomended in cases where the student does not learn the concept the first time.
Version 1.0 contains 5 levels:
Level 1: Orientation – In this level all the shapes have the same volume just different densities. Thus, the differences in the masses of the objects are directly proportional the differences in the densities.
Level 2: Instructional Level 1 – In this level all the shapes and materials are preset. It is intended as an instructional level where teacher instructs the student on the how to quantify the differences in mass.
Level 3: Assessment Level 1 – In this level all the shapes and materials are random. This is meant to test if the students actually know how to find the masses and sort them.
Level 4: Instructional Level 2 – In this level all the shapes, materials, and textures are preset. It is intended as an instructional level where the teacher instructs the students on how to quantify the differenes in mass, go over mistakes from the previous level, and try to seperate the children from preconcieved notions about appearance. All that glitters in not gold.
Level 5: Assessment Level 2 – In this level all the shapes, materials, and textures are random. This is meant to test if the students actually know how to find the masses and sort them, as well as being able to get past the confusion of things not being what they appear. This module may seem a little math intensive and some students may need the assistant of calculators to find the volumes of the shapes.
Version 1.0 contains 5 shapes:
Version 1.0 contains 6 materials:
This module is inteded for use after the students have been exposed to the ideas of mass, volume, and density. This module is much easier to use if the students have the following skills:
Basic Geomotry (understanding of such terms as radius, pi, etc)
