22. 2) Salad Dressing Assessment A teacher is holding a bottle of salad dressing in front of the students. The students can clearly see two layers in the salad dressing, with the oil floating on top of the vinegar. The teacher gently inverts the bottle 2 1/2 times, ending with the top of the bottle pointing down. What will happen to the layers? A-the oil will always be on the top. B- the oil will be on the bottom because the container is upside down C- it is random, sometimes the oil will be on the top and sometimes it will be on the bottom. Which of the above explanations are true? Explain your reasoning... Why did you chose the one you did?

53. Make a claim about your results Word Bank: MoreLess Dense Heavier Lighter Thicker Thinner and give evidence for your claim.

54. 10) Double Alcohol Assessment A teacher holds a container with 4 liquids layered (like our lab). The liquid on the top layer is red. If you doubled the amount of the red layer, how will this affect the layers? Anne says, “The red layer will sink to the bottom.” Bill says, “The red layer will sink under the yellow layer.” Cathy says, “The red layer will sink under the Blue layer.” Daniel says, “The layers will not change.” Who do you agree with with?______________ Why?

55. 10) Double Alcohol Answers: 1.Anne because there to much pressure to it’ll take the red to the bottom (sink) 2.The red layer will sink and mix with blue because the gravity is pulling the heavier weight down. Which is called density of matter. So I believe what Bill says. 3.I agree with Cathy. I feel like the red will sink in with the blue and they will mix and make purple just like it did in our lab. The double of the red density will make it have a heavier volume and that’s why the red will go to the blue. 4. I think if you double the amount of the red liquid then it wouldn’t change it would just stay at the top.

65. Where does this fit in to the Next Generation Science Standards? MS.PS-SPM.b. Structure and Properties of Matter Students who demonstrate understanding can: Plan an investigation to generate evidence supporting the claim that one pure substance can be distinguished from another based on characteristic properties. The performance expectation above was developed using the following elements from the NRC document A Framework for K-12 Science Education: Science and Engineering Practices Planning and Carrying Out Investigations Planning and carrying out investigations to answer questions or test solutions to problems in 6–8 builds on K–5 experiences and progresses to include investigations that use multiple variables and provide evidence to support explanations or design solutions. Plan and carry out investigations individually and collaboratively, identifying independent and dependent variables, and controls. (b) Collect data and generate evidence to answer scientific questions or test design solutions under a range of conditions. Disciplinary Core Ideas PS1.A: Structure and Properties of Matter Pure substances are made from a single type of atom or molecule; each pure substance has characteristic physical and chemical properties (for any bulk quantity under given conditions) that can be used to identify it. Crosscutting Concepts Structure and Function Complex and microscopic structures and systems can be visualized, modeled, and used to describe how their function depends on the shapes, composition, and relationships among its parts, therefore complex natural and designed structures/systems can be analyzed to determine how they function. Structures can be designed to serve particular functions by taking into account properties of different materials, and how materials can be shaped and used.
