6.A Plan and carry out an investigation to support a claim about how the inputs to a plant are related to what the plant cell can produce from chemical reactions in the chloroplasts (outputs).

• Students can identify what independent variable they are changing and should only be changing one variable at a time.
• Students can set up a data table that corresponds to their dependent and independent variables.
• Students plan the number of trials and time length to run the simulation to make a fair comparison.

• Ask the students what input they are changing to see how it affects the outputs (food made). Refer students to Simulation Procedures part A, and/or B for the directions to follow as they run the simulation.
• If your students struggle with how to set up the data table, remind them that back in Lesson 2, when we used the food indicators to collect data about whether the hydroponic plant food solution contained food molecules, they used a table to keep track of the data they collected.
