It allows the students to practice collecting data, analyzing data, and then constructing a graph using the collected data. This can be used for almost all grade levels. The analysis would just need to be enhanced for higher grade levels.
This project is designed as a home project but could also be done in class or in groups. The students develop a question then collect data on their question. From the data collected, a graph is built and analyzed.
This packet includes a letter to go home, the data collection sheet, some questions to analyze the graph, as well as a grading rubric.
