Welcome 1 Find your assigned seat 2 On

Welcome! 1. Find your assigned seat. 2. On your warmup paper complete the question for Thursday: Which of these items is an element, mixture and compound? A B C

Now you are going to create your own lab and separate a mixture! 1. It is up to you (the scientist) to find a way to solve this problem! You need to separate this mixture physically. 2. Tomorrow you will be given a mixture of sand, salt, iron filings (little pieces of iron), and mini marshmellows! 3. How could you possibly separate this mixture using: a strainer, ring stand, candle in holder, beakers, cup with holes in the bottom, a tray, a magnet, and goggles.

TODAY • You are going to write the lab procedure for how you are going to separate this mixture (sand, salt iron filings, mini-marshmallows) using the tools mentioned (a strainer, ring stand, candle in holder, beakers, cup with holes in the bottom, a tray, a magnet, and goggles)! • Step by step you need write out IN DETAIL how you will start, continue, and finish separating this mixture! • This procedure will need to be a numbered list!

What does it mean to be detailed? • We MUST include amounts, cannot say I am adding water, need to say how much of a substance is being added! • Need to state when, where, and how things are being added! • Example: PB&J -> -Spread the peanut butter on the bread (Where on the bread? All of it? Spread with what? Your hand? ) NEED to be as specific as possible, so this would make sense to someone who is just walking into the room and has no idea what is going on!

HOW to write a hypothesis! 1. A hypothesis is a prediction of what you think your result will be! 2. A hypothesis is an “if” “then” statement and may need to include “because” • “IF _____(I do this), then ____(this)____will happen. ” Example: If I place two plants in a closet with no light, then they will not grow as tall as the plants placed in the sunlight.

The results! • Need a three sentence paragraph to include: (What did I observe happen, and I was -> I was able to separate the mixture by _______, and ____. -> I was unable to separate the mixture by _______, and _____.
