This project explores how varying pH levels affect tadpole growth. We hypothesize that changes in water pH will influence the number of tadpoles that thrive. The investigation involves six steps to create a comprehensive graph: identify variables, determine ranges for X and Y axes, label the graph with a title and axes, plot data points accurately, connect the points for observation, and include a key for clarity. Through this process, we aim to visualize the relationship between pH and tadpole populations, providing insights into optimal growing conditions.

Constructing a Graph
Question and Hypothesis • I wonder what pH is optimal for growing tadpoles • If I change the pH of water, the number of tadpoles will change
6 steps to making a great graph • What to do….
Identify the Variables STEP # 1 Independent= __________ Dependent= ___________
STEP # 2 Determine the Range Find the highest number Equation= You may need to round… Always round UP! X axis scale: ___ Y axis scale: ___
STEP # 3 Label the graph • Must have: • Title • X Axis • Y Axis
STEP # 4 Plot the points
STEP # 5 Connect the lines… Never do a bar graph
STEP # 6 Make a Key
