Need help with assignment!

Step 1 is to look at datasheet for the temperature sensor and figure out what its "output" is for the range of temperatures you are given. (It is basically a variable resistance so its "output" is ohms, its input is temp.). It would also be helpful to google for op-amp applications + temperature sensor. This is your literature review phase.

Next you'll have some ideas about how to turn this changing resistance into a proportional changing output-voltage.

How do you sense a changing resistance? You apply a known DC bias to it and either measure a changing current, or you measure a changing voltage by placing it in a voltage divider.

At this point, you should understand your sensor well enough to decide on the best topology (e.g. inverting or non-inverting). You're still in school, so you probably aren't used to having to think about this, but make sure you're aware of basic op-amp non-idealities that may affect your system. E.g. offset voltage, input bias current, voltage swing limitations (e.g. is your op-amp rail-to-rail? how "rail-to-rail" is it?). I suggest making this "part 2" of your literature review. I suggest reading the section on op-amps in The Art Of Electronics. It will give you a practical treatment that you probably haven't been given in school.

Finally, for single-supply op-amp design I recommend checking out the section for single-supply op-amp design in "Op-Amps For Everyone". It gives a systematic method for designing op-amp circuits with a single supply. This is the third literature review.

Notice there is a lot of literature review to be done before doing any design. You might want to split it up as a group, and also assign someone to start learning LTSpice.
