Create a hamster maze out of wood, cardboard or glass. At the end of the maze, place a treat for your hamster. Time the hamster going through the maze. Change the layout of the maze and chart which maze is the easiest and which is the hardest for your hamster. Conclude the reasons for your results.
Change the types of food you feed your hamster for seven days. Each day, give the hamster a different type of food. Observe the behavior of the hamster throughout each day and chart your findings on the food effects.

Trick your hamster into thinking that it is day when it is really night and night when it is day. Use a dark room or a dark cover over the hamster wheel during the day and install a small infrared camera in the hamster cage. Observe the hamster patterns during the pretend day and pretend night, then again in the real day and real night.
Create a battery-powered apparatus and hook a conductive wire to the hamster wheel. Allow the hamster to run on the hamster wheel to produce electricity.
Create a glass barrier in the hamster cage. Introduce another hamster on the opposite side of the current hamster. Observe the behavior the hamster has before the new hamster and after.
Stimulate the hamster with various types of smells. Observe how each smell makes the hamster react.
