PRESERVING FOOD CHALLENGE

Mar 14­14:19

Scenario: Utterly Joyous, you look proudly at the fish that you have caught, using a home­made rod, from the nearby stream.

Scenario: However, you quickly realise that the fish will soon go off and you must preserve them. You have noticed close­by a mouth of a river which runs into the sea. You can now gather salt­water with your bucket. 

Mar 14­14:19

Scenario: Luckily, you have gathered some water and fortunately did not drown in the ferocious currents. You know that water contains salt but how do you get the precious salt separated from the water so that you can use it to preserve your fish?

Experiment time!

Equipment at your disposal:

salty water

saucer

sun­light as heat source

(If no sun, then use a hot are in your home to mimic the jungle heat)

cup

Scenario: You decide to the pour salt water (solution) into the saucer and plastic cup. You are careful to only put a little amount in. You place the container in the sun light (or other warm area in your home) so that the process of evapouration can begin.

Prediction:

• How long will it take to evaporate? 

• What will happen when the water has gone? Why?

Conclusion:

• Were you right? Why
