Storyline Narrative 8.1.3
First the teacher will burn a piece of the paper in front of the students. This phenomenon will then help students generate a list of observations and form questions about how to know when a chemical reaction has occurred.
Students will identify common chemical reactions that they are familiar with. The teacher will fill in with a couple other reactions the students may not have mentioned. Students will conduct an investigation and analyze the data to identify patterns in what changes during a chemical reaction.
Students are presented with situations where chemicals are mixed and some cause chemical reactions and others that do not cause a chemical reaction. Students will analyze and interpret the results based on the patterns they have identified previously to determine if they are a reaction or not.
Students will plan and conduct an investigation to test whether mentos and diet coke is actually a chemical reaction.They will analyze and interpret the data using the patterns they have identified in property changes.
Then using their evidence they will make the argument as to whether the mentos and diet coke phenomena is a reaction or not.
Episode 1
​
Question
What happens to a piece of paper when you burn it? Is it a chemical reaction or not?
Snapshot
The teacher will burn a piece of the paper in front of the students. Students generate a list of observations and form questions.
Snapshot
Students observe and conduct several chemical reactions in a rotation style lesson. Within each chemical reaction students identify the patterns that is demonstrated.
Students observe, analyze, and interpret what is happening in each example and what evidence is there to prove chemical reaction has taken place.
Episode 2
​
Question
What are the patterns evident in a chemical reaction?
Episode 3
​
Question
Is it a chemical reaction happening?
Snapshot
Students observe several chemical reactions and non chemical reactions. They analyze and interpret the patterns that are demonstrated and determine if it is a chemical reaction happening.
Episode 4
​
Question
Is it a chemical reaction or not, and why?
Snapshot
Students will plan and conduct an investigation to test whether mentos and diet coke is actually a chemical reaction.They will analyze and interpret the data using the patterns they have identified in property changes.
Then using their evidence they will make the argument as to whether the mentos and diet coke phenomena is a reaction or not.
