Today we had Olga from Science World’s SIS Program come to teach us!

We learned that there are 4 clues to show us that a chemical change has happened:

  1. colour change
  2. bubbles
  3. change in temperature
  4. new compound properties

We also learned that scientists need to be persistent, and that not all glue is created equal!  🙂  What did you learn from the presentation?  What was your favourite part?
