You explain what you think and WHY you think that.You use EVIDENCE to support your answer.A6 Number 1 rubricWrite an expanded answer for #1. DUE TOMORROW

3 2 1Your response is complete and correct if:YesAlmostAnswer attempted but inaccurateYou give a specific, correct answerYou use evidence to support a logical interpretation of the data.You evaluate the source, quality, and /or quantity of evidence. Comments:

Total:

Divide by 3: **Grading***4= 953=802=701=60*** The only way you can get a 4 (95%) is to get all 3s on the top portion. If you have a 2 or a 1 then you are unable to do the bottom half .

For right now, to make a 4 you will only need 1 yes in the second box. Later on in the year you will be asked to have 2, 3, or 4.

Bonus:Anyone and everyone is capable of getting the bonus. There is not a minimum or maximum requirement. To get a 100%- you must have all 3s on top, at least 1 yes on the bottom, and a good opening and closimg. The highest one can make is a 105% (All 3s on top, at least 1 yes on the bottom, a good opening and closing, and type your answer)

Level 1: Bad science- 1 week to revise and resubmit -65%You identify evidence and orYou explain what you think the evidence meansLevel 2: Good science; need more info-75%You explain what you think the evidence means. You use some evidence to support your ideas. Level 3: Good science; info is complete-85%You use evidence to support a logical interpretation of the data. You evaluate the source, quality, and/ or quantity of evidence.Level 4: Great Science -95%You accomplish level 3 and go beyond in some significant way such as:You present thorough examination of evidenceYou connect your ideas with the science concepts learned. You provide an explanation for why alternative ideas were discarded. You provide suggestions for further relevant investigations You include a diagram or visual to clarify your ideas.

Exit TicketTake out a 3x5 card and put your name, todays date, and this period in the upper right hand corner.Answer the following question on your card:Would you feel safe pouring this mixture down the drain? Why or why not?DUE AT THE END OF THE PERIOD!!!

A6 Separating Liquids - VocabularyToxic -A41. Chemical property: A specific result of a test with a chemical reagent. Chemical properties include pH, the production of a salt when an acid reacts with a metal, or a unique color change in a chemical reaction. 2. Miscible: Two or more substances that can be mixed together in any ratio to form a single phase without separation. 3. Physical property: A characteristic of a substance or material, such as color, density, flexibility, hardness. These properties help identify pure substances and never change whether there is a large sample or very small sample of material. They are intrinsic properties.

A6 Separating LiquidsKey Concepts: Write these down and give an example from the previous activities where this is shown.Substances have characteristic properties such as density, that are independent of the amount of the sample.Ex. No matter how much or how little we have, Liquid B will always float on top of Liquid A.Scientists use appropriate tools and techniques to gather, analyze, and interpret data.Ex. pH paper is used to tell if something is corrosive.Scientific explanations emphasize evidence.Ex. We are determining what liquid A and B are based on their characteristics, NOT by guessing.A6 Lab CheckTitle, Challenge, Safety 5 pointsData Table with data 5 pointsAll Analysis questions answered 5 pointsAdditional WorksheetsKey Points with examples 5 PointsTotal = 25 points
