Some of the easiest elementary school science projects include observing fish, M&M geometry, M&M math, play-doh math and measuring up. Elementary science school project descriptions can be found on websites such as Science Fair Extravaganza and Science Buddies.
The goal of the fish observing project is to learn about various factors that influence the behavior of fish. It requires a fish tank and a logbook for recording observations. A control variable that will be kept constant must be chosen; for example, water temperature or the amount of light could work. Next, an independent variable is chosen, such as the species of fish. In that case, different species of fish are introduced to a fish tank with the same water temperature, and their behavior is then observed. No matter what is chosen for the experiment, however, the fish should be treated ethically like any animal subject, warns Science Fair Extravaganza.
M&M geometry involves measuring the volume of different quantities of M&Ms in cubic centimeters. Similarly, the M&M math project introduces children to the chaos theory and statistics by using different color M&Ms to demonstrate the concept of predictability. For the play-doh math project, children must make different shapes with the same piece of play-doh. The goal of the experiment is to learn how shape determines the dimensions of an object. Finally, the measuring up project is about accuracy of measurements.
