26. 1,000,000 Question Tom is doing an experiment. His hypothesis is that water runs through gravel faster than it runs through sand or clay. The diagram shows his setup. He plans to pour equal amounts of water into the top of each container and then time how long it takes for water to begin dripping from the bottom of each. Tom puts the same amount of soil in each container. The soil is held in the containers by identical squares of cloth kept in place by rubber bands. The containers are fastened to ring stands. List at least 3 variables in Tom’s experiment. Put a star next to the manipulated (test) variable. Tom is doing an experiment.
