Drill Something with classifying

Take out your signed safety contract and signed syllabus sheet Warm-Up Take out your signed safety contract and signed syllabus sheet

I NEED THIS BEFORE YOU ARE ABLE TO DO ANY LAB!!!!!!! Safety Contracts I NEED THIS BEFORE YOU ARE ABLE TO DO ANY LAB!!!!!!! You keep the rules paper, I only need the signed copy Lab = Next Class

Matter Anything that has mass and takes up space

Introduction to Matter There are 9 petri dishes located around the room with different nuts, bolts, and washers Your task is to classify each of them by representing an element, a compound, a mixture of elements, a mixture of compounds, or a mixture of elements and compounds. You will then define what you believe an element, a compound, and a mixture is

Logistics Please wait until I say to move to go to the next Petri dish You will have 1-2 minutes at each station At the end you will have time to go back to any Petri dish you would like a second look at

At the End: Go back to any petri dish you want to look at again Complete the bottom portion where you are to define: Element Compound Mixture

Sugar (C12H22O11) E – Element C – Compound H – Homogeneuous Mixture M – Heterogeneous Mixture

Pepperoni Pizza E – Element C – Compound H – Homogeneuous Mixture M – Heterogeneous Mixture

Sugar Water E – Element C – Compound H – Homogeneuous Mixture M – Heterogeneous Mixture

Silver E – Element C – Compound H – Homogeneuous Mixture M – Heterogeneous Mixture

Water with Ice Cubes in it E – Element C – Compound H – Homogeneuous Mixture M – Heterogeneous Mixture

A Dilute Solution of Hydrochloric Acid E – Element C – Compound H – Homogeneuous Mixture M – Heterogeneous Mixture

Glass of Orange Juice E – Element C – Compound H – Homogeneuous Mixture M – Heterogeneous Mixture

Salt E – Element C – Compound H – Homogeneuous Mixture M – Heterogeneous Mixture

Question… Is it easier to prove than an unknown substance is an element or a compound?

In your groups… What is chemistry?

Google says… The branch of science that deals with the identification of the substances of which matter is composed; the investigation of their properties and the ways in which they interact, combine, and change; and the use of these processes to form new substances.

In your groups… Why study chemistry?
