ASK A QUESTION: Jimmothy is doing his science fair project. He needs a testable question ,but which one will he choose?
What will be my question?
ASK A QUESTION: Jimmothy is home and making some noodles. But, it seems as he is waiting forever for the water to boil. Then he asks himself...
What if I added salt? If different amounts of salt a mixed in 1 liter of water which amount of salt will make it boil the fastest?
CONDUCT RESEARCH: To find more information, Jimmothy went onto his computer and started researching the problem.
EW!!! Wikipedia! Ew!!!
FORM A HYPOTHESIS: Jimmothy with all of his research done can form a hypothesis.
If different amounts of salt a mixed in to water then the highest amount of salt will make it boil faster because it is the most.
DESIGN AN EXPERIMENT: Jimmothy now is testing his question. He makes sure he has constants. They are the amount of water, size of the pot, the temperature on his stove, and finally his type of salt. He waits for the control of no salt to boil. Then he tests his independent variable. He mixes in 10 g of salt and 20 g of salt in the two different pots. He then waits for the boil or the dependent variable.
ANALYZE THE DATA: Jimmothy put his data in a table and then graph his data.
Amount of Salt
Boiling Time (min)
9 min 38 sec
10 min 20 sec
7 min 54 sec
The more salt that is put in the faster the water boils.
