2. Purifying Challenge Sieving Filtering Distilling
Your challenge is to separate the mixture in front of you into its original components. In todays method you are going to write an equipment list, a method, and a risk assessment for this challenge.
Learning Activity
Which separation techniques are you going to use for this experiment and in which order are you going to do them in?
Sieving
Filtering
Distilling

3. “ I have chosen to use the 300ml beaker because…”
Equipment list
Learning Activity
10mins
Write down a list of all the equipment you think you will require for this experiment. To produce a higher level equipment list justify why you have selected each piece of equipment.

4. Lv5: Detailed list of instructions which includes measurements.
Method
Learning Activity
15mins
Breakdown your method into 3 separate methods (Sieving, filtering, and distilling)
Give a step by step list of instructions on how you are going to do your experiment. (You may also wish to include a diagram to help you.)
Success criteria
Lv4: Simple list of instructions which are simplistic and easy to follow.
Lv5: Detailed list of instructions which includes measurements.
Lv6: Level 5 complete, additional information regarding equipment and health and safety also attached.

5. Then move onto a new piece of work and do the same thing.
Assessment Activity
M.M.I
5mins
Move . Move . Improve
Move round the room and find some ones work to look over. Read their method and their Equipment list and write down three feedback notes. (Positive and negative)
Then move onto a new piece of work and do the same thing.
Finally, improve

6. Risk assessment
Learning Activity
5mins
A risk assessment describes the risks involved with an experiment and methods of reducing those risks. Scientists have to create a risk assessment for every lesson regardless of how dangerous it is.
Learning Activity 1
Brainstorm 5 hazards that are involved with your experiment. Discuss them with your partner, then write down and describe why they are hazards in the hazard box of our risk assessment.
