Saltwater plants of the same species were grown in soil in separate containers with 1 liter of water. All of the plants were the same height at the beginning of the experiment. Different amounts of salt were dissolved in each container as shown in the diagrams. All other conditions were held constant. Measurements for the final height of each plant were provided.
What would be the independent variable in this experiment?
What is amount of salt
300

A science class is asked to compare the speeds of two similar toy boats.
• One student measures the time it takes boat X to travel across a pond 10 meters in length.
• A second student measures the time it takes boat Y to travel the same distance across the same pond.
Which would most likely cause error in this investigation?
What is using two different students to measure the time

These are the outcomes of all chemical changes (4)
What is new substance, new properties, new chemical bonds, new composition
