PRODUCT DESCRIPTION

This PDF file contains three simple lab investigations for students to complete to determine whether mass is affected by physical changes. (Bee-tee-dubs: It's not.) The student instruction sheets have the question identified, procedure written out step by step, and a data table drawn on which to record measurements. There is also a space for students to record their hypotheses, as well as the conclusions they can draw based on the lab activity.

The activities are very simple -- ice melting, salt being broken down, and a sugar cube dissolving in water. They are designed simply to demonstrate the conservation of mass during physical changes. The last activity, sugar dissolving in water, is just slightly more complicated in that students must manipulate the measurements to find the total combined mass by adding the mass of the sugar and the mass of the beaker with water.

Teaching Ideas:
- Students can be broken into groups with each group completing one activity, or all students can complete all three.
- Students can cut around the edges of the instruction sheets and paste them directly into interactive notebooks.
- Students can use these as templates to create similar investigations to determine how mass is affected by chemical changes.

Meets NGSS Standards:

5-PS1-2 Measure and graph quantities to provide evidence that regardless of the type of change that occurs when heating, cooling, or mixing substances, the total weight is conserved.

DCI PS1-B When two or more substances are mixed, a new substance with different properties may be formed. Total mass remains the same.
