PLEASE HELP!!!
• In a controlled experiment, you change one variable while keeping all other variables constant for each test or experimental setup. That way, you know that any differences in results are due to the one variable that was changed. In your investigation, which variable will you change for each test? Which variables will stay the same? What observations will you make that is, what kinds of measurements will you take to help you compare the results of the tests?
2.Do you think the results of your investigation could be compared to weathering and erosion of rock
in the natural world? Why or why not? How is your experimental setup different from real-world
conditions? Is there a way that you could improve your setup to better match the real world?
