Independent Exploration Task- Ellen Ryan
The Effect of Temperature of the water on the period taken to reduce Salt
Aim: To see the a result of water temperature on salt.
Speculation: If the heat of the drinking water is improved the time used for the salt to melt completely will probably be shorter.
Heat resistant mat
Stirring fishing rod
Basic safety glasses
Plastic tea spoon
Consider beaker and fill with 100ml of water
Evaluate 5 grams of sodium, put aside
Place beaker above Bunsen burner
Hold thermometer just previously mentioned base of beaker
Heat to desired heat
Remove from Bunsen burner and place about heat evidence mat
Add prepared sodium and start termes conseilles
Use stir rod to stir right up until salt can be dissolved
Quit timer and record time
Repeat procedure three times to ensure it is a fair test Duplicate entire way for each temperature

The effects of this experiment show that salt dissolves quicker in water using a higher heat. In the 12-15 tests that have been completed, only two were unreliable demonstrating the theory that was given in the hypothesis and completing the goal of the experiment. Errors:
Errors that happened within the test were just like overheating the water, and needing to begin once again, adding to much salt to the heated water and negelecting to start the timer following having put salt in the heated normal water. Improvements:
Improvement that could have already been made happen to be
Since proved in the experiment the time taken for salt to dissolve can be shorter the bigger the water temperatures is. The...
