What did we do this week?Mrs. Miret M.Ed.

Clermont Middle School

8th Grade Physical Science

9/21-9/22 LAKE SCIENCE ASSESSMENT

• You will be starting/continuing the Lake Science Assessment today. • Take out #2 pencils• Take out your cell phone or other electronic device and turn it off.• Place your devices on the long brown table at the front• Put all of your remaining personal items on the lab tables and return to your seat•Wait for instructions and materials

9/22 AFTER LSA What do we do when we finish?Measurement and Scientific Tools (NOS12-18) Activity#10 ESSENTIAL QUESTIONS

1. Why did scientists create the International System of Units (SI)?

2. Why is scientific notation a useful tool for scientists?

3. How can tools, such as graduated cylinders and triple-beam balances, assist physical scientists?

9/23 SCIENTIFIC PROBLEM SOLVING Activity 9Answer key to page 62-63 worksheet.1 A / Hypothesis 6 Experimental Group

2 A / Mass 7 Variable 14 Scientists used models to perform mathematical calculations. These helped them to determine that the bridge was not overloaded when it collapsed.

3 B / 5.234 x 10 to the 10th power

8 Constant 15 Example: Critical thinking skills would allow me to compare what I already know to the claim about the pimple cream. For example, I know that pimples are not something that can be cured overnight, so I would dismiss the claim about the pimple cream as unreliable

4 Technology 9-12 See chart on next slide

5 Scientific Notation 13 All scientists use the SI system so that they are using the same mathematical language.

Activity # 10 9-12 Interpreting a Table

INTERPRETING A TABLEDirections: Complete the table by choosing numbers from ythe bank and writing them in the correct spaces. Each number is used only once.

9/22 Measurement and Scientific Tools (NOS12-18) Activity#10 ACTIVITY INSTRUCTIONS

•Get your textbook•Take out your INB•Get a copy of the lesson outline•Do the lesson outline as CORNELL NOTES•Write the COMPLETE SENTENCE and UNDERLINE the answer on the right hand side.•You will add your questions and your summary when you are finished.

Answer Key for ACTIVITY #10MEASUREMENT AND SCIENTIFIC TOOLS/notesMGH page 22-23

A DESCRIPTION AND EXPLANATION

1. A spoken or written summary of observations is called a DESCRIPTION.

2. An interpretation of observations is called an EXPLANATION.

B THE INTERNATIONAL SYSTEM OF UNITS

1. The International System of Units (SI) is the internationally accepted system of MEASUREMENT.

2. The seven standards of measurement, or BASE SI units, are the meter, kilogram, second, ampere, Kelvin, more, and candela.

3. In the SI system, factors of ten are represented by PREFIXES such as milli-.

4. Any SI unit can be converted to another by multiplying or dividing by a power of TEN.

C MEASUREMENT AND UNCERTAINTY

1. A description of how similar or close measurements are to each other is called PRECISION.

2. A description of how close a measurement is to an accepted value is called ACCURACY.

3. All measurements have some degree or error, or UNCERTAINTY.

4. Scientists use SCIENTIFIC NOTATION to write or display very small or very large numbers.

5. The expression of error as a percentage of the accepted value is called PERCENT ERROR.

D SCIENTIFIC TOOLS

1. A science JOURNAL is used to record observations, write questions and hypotheses, collect data, and analyze the results of scientific inquiry.

2. To measure the masses of objects, you would use a BALANCE.

3. Two common types of balances are the ELECTRONIC balance and the triple-beam balance.

4. Laboratory GLASSWARE is used to hold or measure liquids.

5. To measure the volume of liquids, a scientist would use a GRADUATED CYLANDER.

6. The temperature of substances is measured using a THERMOMETER.

7. The Kelvin is the SI unit for temperature, but in the science classroom temperature is often measured in degrees CELCIUS.

8. Scientists use CALCULATORS to make quick calculations using their data.

9. Some uses of COMPUTERS are to prepare research reports and to share data and ideas

a. Hardware is the PHYSICAL components of computers, such as the monitor and the mouse.b. Word processing, spreadsheet, and presentation programs are examples of SOFTWARE programs that are run on

computers.

10. Electronic PROBES can be attached to computers and handheld calculators to record measurements.

E ADDITIONAL TOOLS USED BY PHYSICAL SCIENTISTS

1. To estimate the acidity of a liquid substance, you can use ph paper.

2. A HOTPLATE is a small heating device that can be placed atop a table or desk.

3. To measure the weight or the amount of force applied to an object, you could use a SPRING SCALE.

9/23-9/24 Goal: Complete notes from this week.Activity # 9, and #10

•Please locate your INB.•We will begin with the Problem Solving notes. These should be attached to your INB as activity #9•We will then work on the Measurement and Scientific Tools. This is activity #10

REMINDER: ACTIVITY # 8 (From last week)GALILEO GALILEI

Please make sure you complete the graphic organizer for The Galileo Galilei. See last week’s ppt for details and reference links needed to complete this task.

9/24 SCIENTIFIC PROBLEM SOLVING GALLERY VOCABULARY REVIEW / Exploration #1

• Take out your INB.

• You will be visiting each of the displays around the room.

• For each of the vocabulary words you will be drawing an example of what it means.

• You may use the examples given or create your own.

• If you create your own example, it needs to make sense to you and correctly represent the science terminology.

• The photos from the problem solving gallery will be posted over the weekend. 9/26-9/27
