Product Description
Are you looking for a great experiment to help with the steps of the Scientific Method? This one has some fizzing and bubbling that will be a hit with your students!

This investigation uses effervescing tablets (commonly called Alka Seltzer). Students will use the tablets to learn more about what makes dissolving happen more quickly. After trying a few tests with the effervescing tablet, you have the option of letting students choose more variables to test to extend the experiment. Finally, they will conclude what makes the tablet dissolve the fastest!

The package includes step-by-step procedures, helpful hints, and management ideas for making this work smoothly for you. Lab sheets are totally optional, although the data table is used to make recording more efficient for students. You can always have students design their own data table to record the results of the experiment.

This experience will take one class session to complete.

You will need materials along with this package, including: Effervescing Tablets, Water, Vinegar, Salt- 1 teaspoon per group, Small cups – clear is better- in 2 or 3 ounce sizes, Microwave or hot plate, Knife (for teacher use only), Timer or stopwatch, Paper towels, and Safety Goggles.

This package specifically includes: Cover, Teacher Background, Materials and Preparation page, 3.5 pages of Step-by-Step Procedures for Teachers, 1 page Student Lab Sheet, Extra page of information about Variables, 2 pages of photos, 1 extra page of Helpful Hints, and a Credits page. Instead of a student answer sheet there are samples of student work included in the teacher directions.
