Let s talk about feet foot lab

Let’s talk about feet……FOOT LAB!!!!


How many feet presentation

How many feet: Presentation

Create a report and present it to the class when called upon. I will ask you 3 questions.

What was your method for getting the measurement? This will include a diagram.

How did you maximize the precision?

What is the usefulness of your measurement for someone going to the hardware store to buy a rope the same length as the distance across the room?


Accuracy and precision

Accuracy and Precision

  • The Goal

  • Measure the width of the hall as precisely as you can using “feet” as your units of measurement.

  • Resources

  • Strip of adding machine tape

  •  Your foot


Websites

  • 12.9 ft which is the same as 12ft 11 in


What is the difference between accuracy and precision

What is the difference between accuracy and precision?

  • Accuracy is the real deal; the truth; the accepted value

  • Precision has two meanings:

    • How repeatable the measurements are (range)

    • How small the interval of measurement is

  • In the foot lab, what aspect of precision was being investigated?

  • What do you think the goal is in science regarding accuracy and precision?

Order of operations

Order of Operations

When there is more than one operation involved in a mathematical problem, it must be solved by using the correct order of operations .

Remember, calculators will perform operations in the order which you enter them, therefore, you will need to enter the operations in the correct order for the calculator to give you the right answer.

Why scientific notation

Why Scientific Notation?

  • It makes it easier to work with very large and very small numbers.


Given the following 2 00 x 10 4

Given the following: 2.00 x 104

  • The first part is called the coefficient (the 2.00).

  • The second is called the base (x 10) and exponent (4).

  • Proper scientific notation requires the coefficient to be between 1 and 9. The base is always x10. If the exponent is positive, the number is greater than 1 and the decimal is moved to the right as many times as the exponent to convert to standard form.

  • If the exponent is negative, the number is less than 1 and the decimal is moved to the left as many times as the exponent to convert to standard form.

  • Use the EE key – not the carot!

  • Get a calculator

  • Pick up all 3 pages at front

  • The short dim analysis ws is what we are working on today

  • The long dim analysis ws is your review for next Thursday’s test. There will also be safety questions on the test.

  • NOW: If you have 6,230 cm, how many

    • Km?

    • mm?

    • Dm?

Look at the ladder

If you are going down the ladder you add places (ie move the decimal right)

If you are going up the ladder you subtract places (ie move the decimal left)

Converting up on down the metric system using dimensional analysis

What do you have?

What do you want?

Is your answer going to be larger or smaller than the starting number?

What do you know?

Remember you must be able to cancel out all units except the one you want to end up with


Step 1

Step 1

Write down the number and unit that you are starting with


Step 2

Step 2

Find out how to arrive at your final unit by using known conversion factors


Step 3

Step 3

Set up your conversion factor so that the units cancel


Example

Example

Convert 5 m into km:

Step 1: you start with 5 m

Step 2: you need to get to km

Step 3: you know that: 1km = 1000 m

Step 4:

5 m X 1km =

1000 m

0.005m

**Always multiply every number across the top ,then multiply every number across the bottom. Finally divide the product of the top by the product of the bottom. Record number and unit.

You are an incredibly valuable employee.  Your boss wants to reward you so she offers you two options.  You can either work 10 days straight and receive one million dollars or you can earn a dollar per second up to one million dollars.  You would like to buy an elite condo in the Bahamas that costs exactly one million dollars.  Which deal will allow you to purchase the condo first?  (Assume that you work every second of every day in both cases.)  Your boss is in a hurry to a meeting so you only have five minutes to decide. 

Which do you choose?
