Slide 1 - Separation challenge
- By Connor fellows
Slide 2 - Aim: To successfully separate the 5 substances
Slide 3 - Materials
- Salt, Iron Fillings, Sand, Foam, Saw Dust, Watch glass, Bowl, Sieve, Beaker, 100mL x3, Bunsen burner, Magnet, Plastic bag, Watch glass, Funnel, Retort stand, Stirring rod, Funnel, 500mL beaker, Rice, Filter Paper.
Slide 4 - Method
- 1. Use a magnet to separate the iron fillings
- 2. Pour the remaining mixture into water
- 3. Stir the mixture around
- 4. Pour the mixture into the filter paper leaving the foam and sawdust behind
- 5. Use a sieve to separate the foam from the sawdust
- 6. Pour the filtrate from filter paper into a watch glass above a Bunsen burner and 1L beaker
- 7. Heat the salt water leaving the salt crystals behind
Slide 5 - Results
Slide 6 - Risk assessment
Slide 7 - Discussion part 1
- The experiment went well and we ended up separating all the mixtures.
- To start with we used the magnet to remove the iron fillings from the mixture and we put them into a beaker.
- After that we put the mixture into a separate beaker and put in some water, then waited for the sand to float to the bottom and the foam at the top. We then scooped of the foam and continued.
- Thirdly we put the mixture through filter paper and made the salty water drop into the beaker below, leaving the residue of rice and sand.
- We then put the salty water into a watch glass above the Bunsen burner and evaporated the water, leaving the salt crystals behind.
Slide 8 - Discussion part 2
- We then put the filtrate mixture from the filter paper into the sieve, separating the sand and the rice.
- We then had all the 5 substances separated from each other.
- We used at least 3 habits of mind, finding humour. We found a way to have a laugh and have fun. We also used managing impulsivity. We were extremely patient, at first we didn’t think it would work but in the end it did. We thought flexibly. If we didn’t think something would work, we slightly changed it so it would.
Slide 9 - Variables
- Some of the controlled variables were things like evaporation, floatation, filtering etc.
- An example of the experimental variables are the 5 substances, salt, foam, rice, sand and the iron fillings. Also the equipment, we used could have changed but we decided to use what we were given.
Slide 10 - Conclusion
- In the end we managed to separate all of the substances successfully using 5 techniques, evaporation, crystallization, floatation, filtering and magnetism.
