The Nature of Science

ACT Opener Keep the opener sheet with you for two weeks

Write the question and answer it

Which statement is always true for a compound? A. It is homogeneous B. It contains only 1 element C. Its chemical composition varies D. It decomposes by physical means

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: The Nature of Science “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

Notes (keep in binder) What is science?

Observing and knowing the physical world Theory- the most logical explanation of

events that occur in nature Law- A theory that has been tested

many times and is accepted as true

Notes Scientific Method- systematic approach

to problem solving Generally 6 steps (you may have learned

5) Stating a problem Gathering information Forming a hypothesis Performing experiments Recording and analyzing data Stating a conclusion

Opener Make sure to copy the question and the

answer

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

Notes Can you think of ways for us to describe

each?

Opener Copy the question and the answers

When Alex distills Substance X, he obtains 3 different pure liquids with boiling points of 150°C, 250°C, and 350°C. How should Alex classify Substance X A. Element B. Compound C. Mixture D. Molecule

Review Scientific Method

Independent Variable? Dependent Variable? Control?

Notes Variable- a factor being tested

Two types Independent variable- the one you change Dependent variable- the one that changes

on its own control- any factor that remains the

same Great experiments have lots of controls

Notes Hypothesis-

Educated guess/proposed solution What makes a good one?

Branches of Physical Science Chemistry- the study of what substances

are made of and how they change Physics- the study of forms and energy and

laws of motion

Class example

Scientific Method Practice Work alone

10 minutes

Work in pairs 10 minutes

Check your answers with another group 5 minutes Decide on correct answers Group of four will be graded Turn in one paper with four members’ names on it for actual

grade

MythBusters Method Watch this 2 minute clip

Fill out the worksheet that goes along with it

Listen carefully, they cover information quickly

Target Check On a piece of paper (to stay in your

binder) List the steps of the scientific method Explain each step in your own words MUST be complete sentences!!!

Homework More practice

Complete the worksheet for homework Due TOMORROW!!!!!

Opener Copy question and answers

Which set contains only physical properties? A. Color, taste, ability to rust B. Boiling point, solubility, viscosity C. Density, flammability, freezing point D. melting point, odor, reactivity to light

Review A lot of practice with variables and

controls

Homework Turn In

Change in Schedule

Notes A little different way of taking notes

today

Practice Problems Complete the practice problems

What you don’t get done in class is homework

Opener Copy the question and answers

A chemistry student finds a beaker in the lab containing a mixture of copper(II) sulfate and sand. The student adds water to the beaker, and the solution turns blue. What technique would be best to separate the blue solution from the sand? A. Chromatography B. Distillation C. Evaporation D. Filtration

Review SI units

We have to know these I know it is difficult Keep working

Growth Mindset = “You just don’t know how to do it… YET”

Study Guide Board Each person...

Think of a topic or vocab word to add to our board

Write it on the piece of paper Turn it in

Pre-Test Look at it again

15 minutes Correct things Change things Add more things

Investigate Four Groups

One paper per group

List the steps of the scientific method and how each apply to your investigationg

Problem: Is it a liquid or solid?

Lab!!! Fun with phases or states of matter

Work in groups of 4

Please remember to keep things clean Don’t throw stuff down the drains

Opener Copy question and answers

The label on a bottle of water indicates the bottle contains 455 mL of water. How many liters of water are in the bottle? A. 0.455 B. 4.55 C. 45,500 D. 455,000
