One of the topics you will learn about this trimester is feedback loops. The concept of feedback loops is important because it helps you understand the way many parts of a system work together. You will continue to learn about feedback in nearly every science class you take. Since you may already know some information about feedback, we have designed this pre-test to help us determine where you are starting.
On this "test" you will earn 100% for completing all 10 questions, it doesn't matter if you choose the correct answer. If you are not sure about a question, "I don't know yet," is an answer choice that you would select.
DO NOT LOOK UP ANSWERS ON THE INTERNET....I want to know what you know, not what the internet knows..
Try your best, and don't be afraid to say "I don't know yet." 😄
