Tracy has a nice lesson plan and handout on identifying chemical reactions posted on her website: http://sciencespot.net/Pages/classchem.html#chemreactions . I modified the ppt slides she had posted for her 8th graders to use with my 6th graders as a guided lesson.
I used this lesson after we had already learned how to balance chemical equations using the hands on lesson I created and described below (also found on my Chemistry page):
Balancing Chemical Equations Activity – one of my long time favorite activities. Students will learn how to read formulas, count atoms, create and read chemical equations, and balance chemical equations using a hands on activity with color coded formulas:
- handout/worksheet with directions (pdf)
- coefficient cards (pdf) – laminate and reuse each year
- formula cards (pdf) – laminate and reuse each year
- Answer Key for the balanced equations (pdf)
- Practice balancing equations worksheet (pdf) and more from ScienceSpot.net
We worked through the problems together and I called on students to first identify the chemical reaction and then balance the equation. After a few slides, they began to recognize the types of reactions quickly and had a good understanding of how to identify and balance the equations.
