In this physics lab, students investigate the motion of different skateboarders pulled with various values of constant force. Using skateboarders of different masses and a variety of constant force values, students produce distance vs. time motion graphs for a number of skateboarding trials. Students may develop their own methods for setting up the lab and recording the necessary data. Following data collection, students analyze the data using Newton's second law and discuss differences between trials, the effects of friction, and possible sources of error in the experiment.

Students design and conduct simple experiments using elodea (aquatic plant sold in pet stores) and Bromthymol blue to determine whether plants consume or release carbon dioxide in the process of photosynthesis. Students will record their data which will be used to conclude whether carbon dioxide was consumed or released by the elodea. Through class discussion of student data, students will learn that carbon dioxide was consumed during photosynthesis.
