Review Growth Mindset

Keep trying until you get it Then keep making it better

Test your mindset Which mindset are you? Which mindset do you want?

Unit 1: Matter and Change “I Can” statements

Standards for the entire unit

That is what you will be tested on Keep in your notebook

Unit Pre-Test Answer the Pre-Test questions

Do your best Similar to Unit test

Opener Make sure to copy question and answers

What is the name given to anything that takes up space and has mass A. Compound B. Matter C. Mixture D. Substance

Review Standards and “I can’s”

Pre-Test

Notes (keep in binder) Chemistry- the study of the composition,

structure, and properties of matter, the processes that matter undergoes, and the energy changes that accompany these processes

Broken into 6 types

Notes Organic chemistry- the study of carbon-containing

compounds Inorganic chemistry- the study of non-organic substances Physical chemistry- the study of the properties and

changes of matter and their relation to energy Analytical chemistry- the identification of the

components and composition of materials Biochemistry- the study of substances and processes

occurring in living things Theoretical chemistry- the use of mathematics and

computers to understand principles behind observed chemical behavior

Notes Chemical- any substance that has a

definite composition Not just the bad stuff

Basic research- carried out for the sake of increasing knowledge Discovery by accident

Applied research- carried out to solve a problem Discovery for profit

Notes Classes of Matter

NotesMatter- anything that takes up space and has mass

Mass- NOT, NOT, I REPEAT NOT the same as weight!!!

amount of matter in an object

Pure Substances (elements and compounds1. Every sample of a given pure substance has

exactly the same characteristic properties.

a. Boiling pointb. Freezing pointc. Melting pointd. Density

Ex: water always has a boiling point of 100 C, melting point of 0 C, freezing point of 0 C and a density of l.00 g/ml.

Other pure substances have their own individual characteristics (bp, mp, fp, density)

2. Every sample of a given pure substance has exactly the same composition.

2 kinds of mixtures

Mixture – not the same as a compound. Usually composed of several substances

Opener

• Copy down the question and the answer

Review

• What is matter?

• What are the two MAIN classifications of matter?

• What are the two pure substances?

• What are the two types of mixtures? Explain them

1.homogeneous mixtures

– also called solutions and have the SAME composition throughout. Ex: milk, salt water

a. solute – the substance that gets dissolved. (What you have the least of) Example: salt

b. solvent – the substance that does the dissolving. (What

you have the most of.) Example: water

How Solutions are Made…

2.heterogeneous mixtures – the composition is NOT THE SAME throughout; oil and vinegar, blue cheese salad dressing, etc.

Practice Activity Card Sort

In groups of 2, sort the card cutouts you have into two columns

Column A should start with cards 1 and 2 Column B should start with cards 3 and 4

Place remaining cards into the correct column

GalleryWalk One stays to explain, one moves

Can you group them different ways?
