- In Science experiments, it is very important to “control the variables” so that there is only ONE independent variable and ONE dependent variable. We “control the variables” by making anything else that could change during the experiment into a constant. For example, if you are doing an experiment to find out what material can hold more water, then it is important to make sure all the materials you are testing are the same size. Why is it so important to control the variables? What would happen if we did not control them?arrow_forwardA biology class wanted to study the effect of different materials on the melting rate of ice. They placed pieces of ice, each with a mass of 10g, onto trays. Group 1 was covered in plastic, group 2 was covered in paper, group 3 was covered in aluminum, and group 4 remained uncovered. Each piece of ice was allowed to melt for 15 minutes. Then final mass of the ice, minus the melted water, was recorded at the end of the experiment. Which of the following is the control group in this experiment? Choose 1 answer: Choose 1 answer: (Choice A) A Group 1 (Choice B) B Group 4 (Choice C) C Group 3 (Choice D) D Group 2arrow_forwardAn experiment took place at room temperature (20 ° C).

- When reacted, how does the use of potassium (K+) vs sodium (Na+) change the soap product? Question 26 options: Na+ adds jasmine fragrance and K+ adds a rosemary fragrance to the soap. K+ produces harder, moldable soaps into shapes and Na+ produces softer, liquid soaps. There is no difference between the two cations. Na+ produces harder, moldable soaps into shapes and K+ produces softer, liquid soaps.arrow_forwardWhich of the following can be attributed to water’s high specific heat? A- oil and water do not mix well B-ice floats on water C- sugar dissolves in hot tea faster than in iced tea D- A lake heats up more slowly than the air around itarrow_forwardWhy is the human body a conductor? a)This is wrong: the human body is not a conductor. b)Nerve cells conduct electricity. c)Calcium is a metal, so the calcium in bones makes the body conducting. d)The body cells contains ions and ions conduct electricity. e)Iron is a metal, so the iron in blood makes the body conducting.arrow_forward
