Heating Substances

Dear Parents and Students,

We have been inquiring into how matter can exist in three states: solids, liquids and gases. When we heat a substance it sometimes changes state. Heat can make a solid melt to form a liquid or a liquid boil to form a gas. We are now starting to inquire into which changes are permanent and which are temporary.

This Week’s  Personal Connections Task

You are to conduct two experiments, as directed in your Personal Connection’s Book. 


Experiment 1: Heating Substances Gently
You will need to:

  1. Read the introduction
  2. Gather the necessary apparatus and materials
  3. Read the method
  4. Create a research question for your experiment (What do you want to find out?)
  5. Create you own method using your own words (What you will do?)
  6. Write down you predictions (What do you think will happen?)
  7. Follow the step by step method 
  8. Record your results (What did you observe? Did any of the substances change state?)
  9. Form tentative conclusions (What caused certain substances to change? Why do you think some of them did not change? Are the changes permanent or temporary? Do they change back when cooled?)

Feel free to take photographs to document your experiment

Experiment 2: 
Heating Different Substances at 200 Degrees Celsius
You will need to:

  1. Get adult supervision!!!
  2. Create a research question
  3. Record apparatus and substances being tested
  4. Write a method
  5. Record your results (What did you observe? Did any of the substances change state?)
  6. Draw a diagram to show how your substances changed (before and after diagram, you may use colour)
  7. Form tentative conclusions (What caused certain substances to change? Why do you think some of them did not change? Are the changes permanent or temporary? Do they change back  to the original substance when cooled?)
Feel free to take photographs to document your experiment

Finally, you will need to complete and return the ISOCS student survey.
