7th grade science hypothesis question
posted by Beth .
please help me with this challenge question, as i don't quite understand it.:
Yolanda makes this hypothesis: "If salt is added to water, then the water will boil at a lower temperature." She sets up and experiment to test her hypothesis, but discovers that it actually takes more heat to bring the saltwater to the boiling temperature. Her lab partner, Kevin says" Your hypothesis was wrong--no good at all!"
DO YOU AGREE OR DISAGREE WITH KEVIN AND WHY???
please , help me...
I would disagree with Kevin, because your hypothesis is an educated guess. For a hypothesis there is no yes or no answer. Her hypothesis may be incorrect, but you must remember it is simply a guess, if she had prior knowledge to believe the water would become cooler, then she would be correct in hypothesizing such.
Hope this helps! :)
I would agree with lisa because i think that for a hypothesis ther is no right or wrong answerw. It is simply an educated on the event that is going happen.
I love muffens!!!!!!!!!
i tried the salt in boiling water it dosent work it just gave taste to the heated water
Kevin was correct that her hypothesis was incorrect, but her hypothesis wasn't not useful. All hypothesis's are meant to be learned from, Yolanda learned from her hypothesis. Kevin shouldn't be so rude about Yolanda's hypothesis being incorrect. People don't know everything. That's what experiments where made for, to learn from both mistakes, and to expand your knowledge.
