Directions: Create a data table on the student handout based on the information given below. Use the graphing notes as a resource.
All of the science teachers have a guinea pig. Which of the guinea pigs
ate the most food based on two days on food consumption. On day 1,
Mrs. Garcia's ate 65 gm, Mrs. Brody's ate 105 gm, Mr. Smith's ate 85 gm,
Mrs. Nguyen's ate 93 gm, Mr. Black's ate 150gm, and Mrs. Miller's ate 97
gm. On day 2, Mrs. Garcia's ate 85 gm, Mrs. Brody's ate 90 gm, Mr.
Smith's ate 100 gm, Mrs. Nguyen's ate 150 gm, Mr. Black's ate 85 gm,
and Mrs. Miller's ate 125 gm.
Consider the data and how many columns and rows you will need to
display it.

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
