Mr. W wants to make AMS a nicer place to live. He has created a new sauce that he thinks will reduce the production of body odor associated with eating hot dogs from the school cafeteria. He recruits 100 customers with a history of body odor problems after eating hot-dogs. He has 50 of them (Group A) eat lunch with the new sauce. The other 50 (Group B) eat lunch with sauce that looks just like new sauce but is really just mixture of ketch-up and mustard. Both groups were told that they were getting the sauce that would reduce hot-dog associated body-odor production. Two hours after eating the hot dogs, 20 students in group A reported having fewer body odor problems and 20 students in group B reported having fewer body odor problems. Which people are in the control group? What is the independent variable? What is the dependent variable? What should Mr. W’s conclusion be? Why do you think 20 people in group B reported smelling better? How could Mr. W makes this experiment better? Mr. W wants to make AMS a nicer place to live.

Answer the following questions: Sponge Bob notices that his pal Gary is suffering from slimotosis, which occurs when the shell develops a nasty slime and gives off a horrible odor. His friend Patrick tells him that rubbing seaweed on the shell is the perfect cure, while Sandy says that drinking Dr. Kelp will be a better cure. Sponge Bob decides to test this cure by rubbing Gary with seaweed for 1 week and having him drink Dr. Kelp. After a week of treatment, the slime is gone and Gary’s shell smells better. 1. What was the initial observation? 2. What is the independent variable? 3. What is the dependent variable? 4. What should Sponge Bob’s conclusion be?

Metric Units Mass refers to the amount of matter in an object. The base unit of mass in the metric system in the kilogram and is represented by kg. Standard: 1 kilogram is equal to the mass of the International Prototype Kilogram (IPK), a platinum-iridium cylinder kept by the BIPM at Sèvres, France. Metric Units 1 Kilogram (km) = 1000 Grams (g) 1 Gram (g) = 1000 Milligrams (mg) Which is larger? A. 1 kilogram or 1500 grams B. 1200 milligrams or 1 gram C. 12 milligrams or 12 kilograms D. 4 kilograms or 4500 grams Click the image to watch a short video about mass.

Measuring Mass Top Image: http://www.southwestscales.com/Ohaus_Triple_Beam_750-SO.jpg Bottom Image: http://www.regentsprep.org/Regents/biology/units/laboratory/graphics/triplebeambalance.jpg We will be using triple-beam balances to find the mass of various objects. The objects are placed on the scale and then you move the weights on the beams until you get the lines on the right-side of the scale to match up. Once you have balanced the scale, you add up the amounts on each beam to find the total mass. What would be the mass of the object measured in the picture? _______ + ______ + _______ = ________ g
62
Measuring Mass – Triple-Beam Balance Click here to try an online activity. 1 st – Place the film canister on the scale. 2 nd – Slide the large weight to the right until the arm drops below the line. Move the rider back one groove. Make sure it “ locks ” into place. 3 rd – Repeat this process with the top weight. When the arm moves below the line, back it up one groove. 4 th – Slide the small weight on the front beam until the lines match up. 5 th – Add the amounts on each beam to find the total mass to the nearest tenth of a gram.
