Discussion
1. What is the trend we see in the results?
The trend observed is that…____________________________________________________
2. Why is our data important? (think about why time is important for the three conditions and
why we want to dissolve the Alka-Seltzer quickly)
The data is important because…_________________________________________________
3. What could we have done to improve our experiment? (think about accuracy, number of
conditions we varied, by how much we varied the conditions)
To improve the experiment we could have…________________because…_______________
4. Why did the condition you varied increase/decrease the speed at which Alka-Seltzer dissolves
in water?
___________________________________________________________________________
Conclusion
The hypothesis is rejected/supported because the trend in the data showed ___________________.
