So how about this hypothesis: The higher the mass of potassium cholride added to the water, the lower the temperature gets.
You will need to think about CVs (like vol of water?), IV and DV for your hypothesis.
Hope this helps.
perlimnary tests-what did u do to make sure the variable you measured was right?
writing about the method-dont forget units and fair test-dont just say to make it fair say it will affect your results
your asked about variables too
Don't worry trust me.You'll wing it if you planned well
Add three spoonfulls of salt to 25cm cubed of water in a small beaker. Stir with a thermometer and take note of the temperature. Keep adding a higher mass of salt each time and take note of the temperature change.
Hope this helps
Well the ISA is only 25% of your overall grade I know someone who got 100 UMS in his ISA and Modules 1&2 so when he walked into module 3 he just needed a C in it to get an A* overall
So it doesn't drag your mark down a lot like my teacher said? It is just part of the average?
Which means that I can still get an A*?
