what is the optimum temperature needed for the enzyme amylase to work?
Develop a hypothesis for this question
-What are the independent and dependent variables? How will you make it a fair test? How many different temperatures will you test? How will you measure the results?
-What type of graph would be most appropriate to communicate the results?

Answer:
32–37 °C
32–37 °CAt optimum temperature (32–37 °C), the enzyme is active and therefore consumes less time for starch digestion.
Dependent and independent variables are variables in mathematical modeling, statistical modeling and experimental sciences. Dependent variables receive this name because, in an experiment, their values are studied under the supposition or demand that they depend, by some law or rule, on the values of other variables.
You conduct a fair test by making sure that you change one factor at a time while keeping all other conditions the same. For example, let's imagine that we want to measure which is the fastest toy car to coast down a sloping ramp.
There are 4 ways to take (measure) a temperature: Under the armpit (axillary method) In the mouth (oral method) In the ear (tympanic method)
Results don’t always have to be numeric (although it’s often good if they are) but it’s important that you’ve thought about the evidence that makes it clear that you and your team have done a good job. Ask yourself, which sounds more impressive? “We’ve been working on improving customer satisfaction” or “The team is on a real high this week – because we’ve halved customer waiting times, and we’ve just heard that the number of Excellent ratings from customers has gone up by 20%.”
Taking the time to measure results gives you something that you can drop into conversation easily – and that builds the reputation of both your team and your leadership skills. For example, you could say “I’m really enjoying work right now, the team has delivered all of the last 4 projects ahead of schedule and below budget” or, at interviews “8 out of the 10 recommendations made by the team in our last presentation were adopted by the Board”.
Line Graphs
Line Graphs One of the graphs you will likely use most often is a line graph. Line graphs simply use a line to connect the data points that you plot. They are most useful for showing trends and for identifying whether two variables relate to (or "correlate with") one another.
