This stand alone ACTIVITY#2 of 6 teaches accuracy and precision. This one involves comparing the use of a graduated cylinder versus an Erlenmeyer flask by measuring colored water in both. This can be used as an exploration, an activity, or a lab experiment as it can be altered.
The presentation consists of 12 slides including:
- 1 cover slide
- 1 introduction slide that was included in the original presentation of 6 activities
- 1 slide detailing NGSS standards covered in the original presentation
- 1 slide general content on accuracy & precision with visual and examples on how to use a graduated cylinder (reading meniscus at eye level vs. standing up)
- 1 teacher overview slide
- 1 lab sheet with materials, questions, procedure
- 1 slide data table for activity
- 1 slide - student questions worksheet
- 1 slide - conclusion option #1 with lines to write conclusion.
- 1 slide - conclusion option#2 modified with conclusion written - students have to circle the choices that apply to their experience
- 1 slide - more teacher notes
- 1 slide - my own conclusion slide that went with the original presentation
Additional materials needed: Erlenmeyer Flasks & Graduated Cylinders per group, 2 different colors of food dye (but this can be tweaked to be done without food coloring as well).
