Does type of hair affect the results? 0000001783 00000 n The ingredients of gummy bears are sugar, water, and gelatin, with little water content. For this experiment, the independent variable is gender, because nothing else changes. Science Projects With Three Variables for Kids in Fifth Grade The dependent variable is the amount of sugar that dissolves in each cup of water. So you turn the up the lights in Tray #1 (the independent variable) and the tomatoes get bigger (dependent variable). Our goal is to make science relevant and fun for everyone. 32. 295 0 obj <> endobj You may print and distribute up to 200 copies of this document annually, at no charge, for personal and classroom educational use. The rate of eye blinking is the dependent variable, because it differs according to the sex of the subjects.

Sometimes it is impossible to just change one variable, and in those cases, scientists rely on more-complicated mathematical analysis and additional experiments to try to figure out what is going on. Record the dimensions and mass of the bear again. Water the seeds equally, and place them where . Take two dirty pennies and place them in identical shallow containers that can hold liquid.
