One "mini" lab -or shortened activity- to reinforce or introduce concepts to students. I call these activities “mini labs” because they are simple activities that do not take the whole class period.

This particular lab focuses on the observation of two chemical changes and reinforces or introduces the signs that a chemical change has taken place.

Includes: teacher information, materials list, procedures, helpful tips for facilitating the activities and student handouts/lab sheets

Materials Needed:

Graduated cylinder

Water

2 clear plastic cups

2 eye droppers

Iodine solution

Cornstarch or Potato Starch

Spoon

Vitamin C tablet (Orange Juice Concentrate can be subbed)

MS-PS1-2: Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
