Lesson 1: We learnt about the lab rules.


From this activity, i have learnt about the rights and wrongs in the lab.

Lesson 2: We heated an ice-cream stick and learnt about the types of flames as well as the parts of a bunsen burner.



From this lesson i learnt that luminous flames are less hot than non-luminous flames and that luminous flames produce a lot of soot and is unstable while non-luminous flames do not produce a lot of soot and are stable.

Lesson 3: We mixed chemicals together and watched the chemical reactions



Lesson 4: We observed water boil to a temperature of 100 degrees Celsius.

Lesson 5:We observed the number of swings by the pendulum bob when at different heights.



I learnt that we have to record the time taken for the bob to make 20 oscillations to ensure a fair test.

Lesson 6: We learnt how to use the vernier caliper and the micro meter screw gauge.







We learnt about distillation today, this is just simple distillation and distillation is one of the many methods use to separate physical solutions and suspensions.









This was when we were burning magnesium! its so bright!!!!!!







This is the Benedict solution being boiled. Its show us if it contains glucose!
















This was one of our last experiments, chlorophyll separation
