Some good science experiments for fifth graders include "Keeping a Candle Burning Underwater," "Find Out Why Leaves Change Color," "Potato Battery," "Homemade Thermometer" and "Experiment with Sound Waves." There are many education websites that provide step-by-step procedures for helping a child or student create a fun science experiment.
Students at a fifth grade level in science are beginning to understand the Scientific Method, which is a formulaic process for hypothesizing, testing and theorizing a science experiment. According to several educational websites, students in fifth grade should be challenged with their science experiments while also encouraged to be creative and have fun.
One specific example of a fun science experiment is "Find Out Why Leaves Change Color." In this experiment, curious students explore natural processes through a hands-on activity. After collecting leaves from outside, they use safe household chemicals and heat to discover chlorophyll, a green compound that hides the other colored pigments present in leaves. In the autumn, chlorophyll breaks down, allowing the other pigments to be seen.
While students perform their experiments, they should take notes, observations and photos. After the experiment is complete, they can arrange their information onto a creative presentation board for a science fair, show-and-tell or class project.
