Problem
Mark has to do an experiment for his schools science fair. He decided to
experiment with milk and plants. His ____________ was “What is the effect of milk on
plant growth?” He begins his ______________ by using the internet to identify the
ingredients in milk. He then creates a _________________ that states: “If milk is used
instead of water, then the plants will stop growing.”
