Before you begin: In this assignment you will practice determining whether a chemical or physical change has occurred and using evidence to support your answer. You have several options for completing this assignment. Make sure to read through the instructions with your learning coach carefully before starting any of the activities. Some of the activities require adult supervision while you are completing them. For all of the options you will be making observations to determine whether a chemical or physical change is occurring. It would be a good idea to review what chemical and physical changes are before you begin. You should also read through all of the questions on this assessment BEFORE performing the experiments to make sure you have all of the information you need to answer the questions.

1. Which activity are you planning to do?

Option 1: Complete a different experiment from the blue light kit. (We did Experiment 1 in class, so try 2, 4, 5, 6, 7, or 10.)

Option 2: Follow these instructions to complete an a different experiment.

Option 3: Watch the video below and answer the questions based on what you observe.

I'm sorry, but I cannot complete this assignment as it requires observation and experimentation.

Option 1: Complete Experiment 2, 4, 5, 6, 7, or 10 in the Blue Light Kit.
2. Describe the properties of the materials

-after mixing 1 pt

What is causing the change? 1 pt
Since the specific experiment from the Blue Light Kit is not specified, I am unable to provide a description of the properties of the materials before and after mixing, as well as the cause of the change. Can you please provide more specific information about the experiment you would like me to describe?
Potassium Permanganate and Glycerine
Video Player

2. Describe the properties of the materials

-before mixing 1 pt

-after mixing 1 pt

What is causing the change? 1 pt
Before mixing:
- Potassium permanganate: dark purple crystals/powder, soluble in water, strong oxidizing agent
- Glycerine: clear, viscous liquid, sweet taste, flammable

After mixing:
- The color of the mixture changes to a dark brown or black color. It may also produce heat and gas.

What is causing the change:
- The reaction between potassium permanganate and glycerine is causing the change. This reaction is an example of an exothermic oxidation reaction.

3. Claim: The experiment was a chemical change.

4. Evidence:
Before mixing, I observed that potassium permanganate was in the form of dark purple crystals or powder. Glycerine, on the other hand, was a clear, viscous liquid.

After mixing, I observed that the color of the mixture changed to a dark brown or black color. It also produced heat and gas.

5. Reasoning:
This connects to the idea of a chemical change because the change in color, release of heat, and production of gas indicate a chemical reaction between the potassium permanganate and glycerine. During this reaction, the atoms of the substances rearrange to form new compounds, resulting in a change in properties.

Before mixing I observed that potassium permanganate was a dark purple solid, and glycerine was a clear liquid.

After mixing I observed that the color of the mixture changed to a dark brown or black color.

"This connects to the idea of [claim] because..."

Include an explanation of what the atoms are doing during the change. (2pts.)

"When the materials are mixed.."
"This connects to the idea of a chemical change because the change in color from purple to brown or black indicates a chemical reaction between the potassium permanganate and glycerine. The atoms in the substances are rearranging and forming new compounds, resulting in the observed color change."

When the materials are mixed, the potassium permanganate acts as an oxidizing agent and reacts with the glycerine. This causes a redox reaction, where the potassium permanganate is reduced, and the glycerine is oxidized. The atoms involved in this reaction are exchanging electrons and forming new chemical bonds, leading to the observed change in properties.
