Do Now Work silently. Raise hand to ask Ms.

Hughes anything.

1. How is the periodic table organized?

2. What identifies an element?

3. Does every student get the same quality of education in the U.S.? Why or why not?

Announcements

• Unit 4 test this Thursday

• If you have not taken 3 chemistry tests yet this semester, see me after to arrange a make up

• Retake GLEs for GRADE BOOST

Mystery Element

• Definitely NOT a Metalloid

• 3rd Most Common Element in Earth’s Crust

• Light weight / Good Conductor

• Because it is a good conductor, it makes a great beverage can…but its resistance to corrosion means lots of space in land fills

Chemistry Résumé

•What’s a résumé?- To track your success in Unit 1- It will show you how well you did

on each GLE

•What’s a GLE?

The BIG GOAL:

80% Mastery

of ALL GLEs

Why 80% Mastery?

• Graduate high school

• Pass the GEE Science Exam

• Graduate college

• Solve your own problems

• $$$

If I didn’t get mastery, is that it?

No!

1. Get 20 min tutoring

2. Retake the GLEs you didn’t master

3. Raise your grade

4. Increase future opportunities!

What to do???

• For those who took the Unit 3 test, complete your tracking sheet

• Get calculators from the bin. Return them when finished

• Raise hand to ask questions

• Those without a test to track, track someone else’s

DISCLAIMER (Warning):

• Today’s lesson will probably fill you with a lot of different emotions, including anger and sadness

• Before you stop listening because you find yourself angry or disappointed, listen and remain engaged through the entire lesson – your ideas/emotions might change

• I’m teaching this because I want to be real with you – I want you to know the facts – I want you to feel like you have an OPPORTUNITY to CHANGE things

What is the Achievement Gap

• The Achievement Gap is the difference in success levels between different groups of young people, such as the difference between:– White students and students of color– High-income students and low-income

students– Students in developed (first-world) countries

and students in developing (third-world) countries

Why is it called a GAP?

• There is a BIG GAP (difference) between the success of students from wealthier households and the success of students from poorer households– Many times this also correlates to a

difference between white students and students of color (minorities)

How is the Achievement Gap measured?

1. Standardized Test Scores (LEAP, GEE, ACT, End of Course Exams)

2. Grade Point Average (GPA)

3. High school drop out rates

4. College enrollment rates

5. College completion rates

What the research says…

• The research is not 100% clear about the ultimate causes of the achievement gap…

• There are however, many theories that keep coming up in research…

Possible Causes of the Achievement Gap

1) It is difficult to retain good teachers at low-income schools

2) Low-income schools get less funding per student than high-income schools

3) Students reject Achievement Ideology (he idea that working hard in school will pay off in having a better job or having greater social mobility)

So, what can YOU do?

• Own your own education!• Take 2 minutes to answer this question

in your notes…–Think of a time when you started a new

sport or activity. What was the activity? Did you find it difficult when you began? What did you do to improve?

• Achieving in class works the same way!

“If you don’t know where you’re going,

you’ll wind up somewhere else.”

What’s a Goal Sheet?

• Turned in on Friday for mini-quiz grade

• Must complete top portion

• You and I will track completion of goals during week

• End of week you will complete bottom portion

LET’S CLOSE THE GAP!!!

Done with Unit 3…

Unit 4: The Periodic Table

Test this Friday

Scientific Notation

• System to abbreviate long numbers

• Examples:

• 1.24 x 105 = 124000

• 3.0543 x 10-7 = .00000030543

Rules

• 1 number in front of decimal• x 10 (positive or negative whole number tells # of places to jump)

• Positive makes the number LARGER• Negative makes the number SMALLER

• Examples:

• 1.24 x 105 = 124000• 3.0543 x 10-7 = .00000030543

What are these numbers?

• 2.3 x 10-5

• 4.204 x 108

Types of investigations

• Observation-

• Description-

• Experimentation-

• Classification-

• Literature survey-

Types of investigations

• Observation- use 5 senses + tools to record facts about world

• Description- make observations + inferences about world

• Experimentation- do scientific method• Classification- put things in categories• Literature survey- summarize all the

experiments scientists have done on a topic

Try to think of 1 example of each

• …you can make one up!!!

Investigation examples

• Observation- writing what you see happening when adding baking soda to vinegar

• Description- observations + inferences about adding baking soda to vinegar

• Experimentation- testing hypothesis about effect of amount of vinegar on size of bubbling

Investigation examples

• Classification- classifying matter as elements, compounds, or mixtures

• Literature survey- summarizing all the experimental evidence about brain plasticity

Technology

• Brainstorm examples of technology that helps scientists do their work

Technology aids science in…

• Data analysis– Excel– Other computer programs that analyze large amounts

of data and run simulations• Presentation of findings

– Powerpoint– Video and animation programs

• Collection of data– Microscopes– Triple beam balance

And many other ways!!!

Exit Slip
