Lesson: Candle Model
Teacher: |
Kaylan Duthie |
Unit Theme/Course: |
Human Respiration – 7th Grade Life Science |
Date: |
November 17th |
Timing: |
1 Day |
Rationale/Goal:
· Students will learn about combustion and oxidation through a reading and a model using a burning candle.
· Problem: How could a burning candle be a model for what happens in your body cells?
Overview:
This lab begins to introduce the concept of combustion through the burning of a candle, and has the students identify both the ingredients and products of combustion, which will be related back to oxidation and cellular respiration in future lab activities. The students will learn about the use of Bromothymol Blue as an indicator, including what it indicates for, and to see how it works so they understand the results they get in a later lab.

4A,B) [cognitive,
academic, language, socio-cultural] |
Assessment
Criteria |
Students will understand the process of combustion |
Students will identify fuel and oxygen as ingredients and carbon dioxide, fire, and heat as products of combustion |
Students will learn about the use of Bromothymol Blue (BTB) as an indicator |
Students will state that BTB indicates for carbon dioxide, and explain that indicators are used to show things you can’t see with your eye. |
Students will formulate a prediction and collaboratively conduct and experiment to test it |
Students will write a prediction including reasoning for their prediction, and work as teams to conduct the experiment. |
Students will define oxidation |
Students will define oxidation as the combining of oxygen with another substance. |
EALR:
6-8 INQB Investigate |
Different kinds of questions suggest different kinds
of scientific investigations. |
Propose a hypothesis, give a reason for the hypothesis,
and explain how the planned investigation will test the hypothesis.
Work collaboratively with other students to carry out the investigations.
|
6-8 INQE Model |
Models are used to represent objects, events, systems, and processes. Models
can be used to test hypotheses and better understand phenomena,
but they have limitations. |
Create a model or simulation to represent the
behavior of objects, events, systems, or processes. Use the model to
explore the relationship between two variables and point out
how the model or simulation is similar to or different from the actual
phenomenon. |
