Demonstration Rationale

Context: This demonstration was performed with my partner Seth Wingate, during Block II in my CI 4401 class, under the advisement of Dr. Jeff Goodman.

Impact: As a future teacher, I will use this demonstration to peek students interests in the area of chemical reactions. Students will find out how things at home can be used for scientific experiments. Students will also better understand the chemical reactions in ph indicators and natural acid/base indicators. This will help students see how science is all around us!

Alignment: This demonstration satisfies the requirements for North Carolina School Teachers by the following:

Standard 3: Elementary teachers have a broad knowledge and understanding of the major concepts in science.

Indicator 2: I met this indicator by demonstrating the factors that affect chemical reactions. The demonstration shows students how the carbon dioxide in someone's breath has a chemical called carbonic acid. Students will see how carbonic acid can change the color of an acid/base indicator. Students will also see how there are natural acid/base indicators available for the same experiment.

Standard 15: Elementary teachers encourage underrepresented groups to engage in the schooling process, especially math and science.

Indicator 1: I met this standard by presenting the demonstration to Hispanic girls and boys. I focused on the girls, during the activity, to get them more involved in the demonstration. I discussed with all students how they too can do their own scientific demonstrations at home, with help from parents. I also explained how we used simple things from home to create this demonstration.
