Question

Jordan wants to conduct an experiment to see if plant food makes a difference in how well plants grow. He gets 10 pots and plants a different type of seed in each. He gives plant food to half of the plants and does not give plant food to the rest. He records the amount of plant food given to the plants. But, he decides not to write down the types of seeds he planted.

Answer 2

Answer:

No, because Jordan should have used the same type of seeds in each pot, and should have recorded the type of seeds.

Explanation:For an experiment to be reliable, there can be only one independent variable. In this scenario, there were two. The first was whether or not the plants were given plant food. The second was the type of seed. For the test to be reliable, he should have used the same kind of seed for each plant. Then, some should have been given plant food while the rest were not. If someone else were to repeat the experiment, they would need to know what types of seeds were used. And, they would need to have only one independent variable in order to get reliable results.
