This is the question I want to solve: "How does ___________ affect __________?"
What is the purpose?
200
During the experiment, I will follow procedure steps, measure to collect data, and use my senses to describe what happens. Using my senses to describe what happens is called making _____________.
What are observations?
200
Students must listen to directions and follow them carefully. Unauthorized experiments are not allowed. If a student is confused about the procedure for the experiment, he or she should do this.
What is raise your hand and ask the teacher?
300
The substance that is being dissolved in a solution.
What is the solute?
300
A student dissolves 10g of salt in 90g of water. The solution is then heated on a hot plate to speed evaporation. When the water evaporates completely, how much salt will be left?
What is 10g?

There are independent and dependent variables in science investigations. This is the variable that I can change.
What is independent?
400
This is the phase of the Scientific Method when I will summarize the experiment, including: explain what I did, explain the data, accept or reject the hypothesis, and explain how I can change the experiment in the future.
What is the conclusion?
400
Students should stay seated unless directed to do otherwise. If a student must move around the room, he/she should walk slowly and carefully to avoid these.
