Format
The content is designed to be delivered for multiple grades, whereby we adjust the explanations according to the grade level attending.
Time is allowed throughout the workshop to ask and answer questions. We treat video conferences in the same format as traditional science incursions. Please refer to the supporting .pdf document supplied to you on booking which details all of the pre-class, post-class and during-class experiment materials your class will use.
1. We discuss types of changes that could be visible in a chemical reaction.
2. The presenter initially 'burns a sparkler' and identifies the changes occurring (heat, color, light, sound, movement, gas released etc). This is used as a scaffold for the lesson.
3. Our presenter then performs a number of fire-based chemical reactions.
4. We discuss gas release as a possible change in a chemical reaction.
5. Your class runs 'bicarb balloons' as an experiment.
6. States of matter are discussed as our presenter runs a number of gas release reactions and dry ice demonstrations.
7. Your class runs the 'making slime' experiment.
8. Change in color is discussed as a possible change in a chemical reaction.
9. Acid and bases are discussed as we run a number of dry experiments.
10. We discuss your pre-class experiments 'cabbage juice indicator', 'sugar and skittles' and 'milk rainbow'.
11. Other chemical reactions are run by our presenter to re-enforce the lesson content.
Objectives
Your student will:
- identify changes that can occur in a chemical reaction
- understand that chemical reactions involve reactants re-arranging into new products
- develop an appreciation for the use of chemistry in everyday life
