Objective: Conservation of Matter
Big Idea Application:
During ordinary physical or chemical processes matter can neither be created nor destroyed. It can only change forms.
The overarching essential questions being considered:
What happens during a chemical reaction?
The essential questions being considered:
How could you use your understanding of mathematical equations, to write a science equation showing that the number of atoms at the start of a reaction will equal the number of atoms at the end?
Approach/ Strategy being applied:
Standard Addressed: 5b: Students know the idea of atoms explains the conservation of matter. In chemical reactions the number of atoms stays the same no matter how they are arranged, so their total mass stays the same.

Contribution to student understanding:
The "nature of science" states that, although scientific knowledge is empirically based, it nevertheless involves human imagination and creativity (Lederman & Lederman, 2004). This lesson asks the students to use their creativity to make a display that demonstrates a scientific concept. The understanding they gain should also help them to describe and explain the results of chemical changes seen in nature. Additionally, it helps them determine answers to questions about everyday experiences.
