This experiment was performed to find out if hamsters and mice are able to learn and recall what is learnt. The experiment also compares the speed of learning of hamsters and mice.
Difficulty: Middle school
Comparing the learning abilities of male and female mice
This experiment was performed to find out if the gender of mice will affect their learning abilities and whether there is a co-relation between gender and left handedness or right handedness.

Convergent Evolution: Why bears and seals are more similar than you think
Convergent evolution refers to how different species of organisms evolve to possess similar physical characteristics, in order to adapt to a particular environment. At first look, bears and seals may appear to have little in common other than both of them being mammals. Yet, the skeletal structures of their feet are very similar. In this investigation, you will select a biome and identify a conver
Diffusion and osmosis in animal cells
With the use of eggs, this experiment shows you how different solutions affect an animal cell. The experiment also answers the question of whether substances can pass through a cell membrane.
Difficulty: High school
Digestion and cat food
This science fair project was performed to examine how much of the cat food eaten by the feline is actually digested and absorbed. The tests were done using 4 brands of cat food IAMS, Friskies, Pet Promise and Nutro Natural Dry.

Difficulty: Elementary school
Do ants react differently in the dark?
Test the effect of light and darkness on ants. You may want to have two observatories for this experiment.
Difficulty: Elementary school
Do changes in the environment such as temperature and light affect shrimp in their choice of habitats?
In this lab, you will examine the habitat preferences of the brine shrimp, Artemia. You will use controlled experimentation to determine the thermal, pH, and light environments selected by Artemia. Based on your experience with this lab, you will design an experiment that could be used to survey other variables and other organisms.
Difficulty: Middle school
Do cockroaches have a sense of direction?
First students make careful observations of cockroach anatomy and behavior. Due to the reputation of the cockroach, students find them intriguing subjects of study. Assessing the behavior of these insects in a maze, allows students to decide if the cockroach manifests learning or an inability to learn. The strongest piece of this activity is challenging students to design their own controlled expe
Difficulty: Elementary school
Do homing pigeons find their way home more quickly at different times of the day?
This experiment was conducted to examine if the time of the day will affect the speed at which a homing pigeon will find its way back home Testing was done by measuring and comparing the flight time of a homing pigeon in the morning and afternoon.
Difficulty: Middle school
