Do now! Can you continue the sheet you started last lesson? Hes going to blow! Be careful Good Neutral Excellent MOODOMETER
Yesterdays lesson Know what to look for to see if a chemical reaction has occurred Give some examples of chemical reactions Explain the difference between a physical and chemical change
Chemical reactions – What to look for
There may be a change of colour
Chemical reactions – What to look for There may be a gas given off (bubbles)
Chemical reactions – What to look for There may be an energy change (gets hotter or colder)
Chemical reactions – What to look for New substances are formed, and the change is usually difficult to reverse
Todays lesson Know the meanings of the words reactant and product Be able to write word equations for chemical reactions Know how to collect the gas produced by a reaction
Can you gather around the fume cupboard please?
