Presentation Transcript

  1. Take out • Catalyst sheet • Pencil • Science notebook • Homework should be in a pile in the center of your table • Fill out a Pink Slip if you don’t have your homework

  2. Catalyst Describe the difference between an Independent Variable and a Dependent Variable. Give an example of an IV and DV from a prior lab. Be as descriptive as possible.

  3. Page 23 of science notebook, 10 rows down Everything I know about measurement:

  4. 10 more rows down • If possible, the Independent Variable should be on the left of the data table, and the Dependent Variable should be along the top of the data table • All data tables should include a descriptive title • No naked numbers! • All rows and columns should be clearly labeled • All lines should be drawn with a ruler Tape in Data Table Conventions

  5. Remaining space on page You will measure 3 different dimensions of your table: the length, the width, and the height You will measure each dimension with 3 different tools You have the remaining space on page to create your data table and fill it in Student Collection Data Table:

  6. Homework Update vocabulary section of science notebook using Vocabulary Section of website.

  7. Take out • Catalyst sheet • Pencil • Science notebook, open to Vocabulary section • Pink slip if homework is not complete`

  8. Catalyst What is the difference between a certain and an uncertain digit in a measurement? How many certain digits can a measurement have? How many uncertain digits can a measurement have?

  9. Page 24 of science notebook, 10 rows down Similarities Differences Split section in half vertically

  10. Page 24, 15 rows down Certain and Uncertain Digits in Measurement: When you use a ruler, are you certain of all the digits you write down? Certain digit: A number you know with certainty because of the intervals on the measuring tool Uncertain digit: The estimated digit you read between the intervals on a measuring tool All measurements should have only one uncertain digit

  11. Rest of page Group Table: The dimensions of a classroom table measured with 3 different tools

  12. Homework Complete "Certain and Uncertain Digits in Measurement" on page 25 of science notebook.

  13. Take out • Catalyst sheet • Pencil • Science notebook, open to homework • Pink slip if homework is not complete`

  14. Catalyst 1. Express the length of the following object to the correct number of digits. The measuring tool given is a meter stick, so express your answer in meters. 2. For your answer to question 1, state the digit in your answer that is the uncertain number and explain why it is uncertain. 3. Imagine that you found the measurement above 5 times (5 trials) and then were asked to find the mean length. How many digits do you think your mean value should have?

  15. Homework Discussion

  16. Length, Width, Height Activity

  17. Page 26, split page in half horizontally Create a T-chart in the upper section. List all of the things that make data collected in this class GOOD DATA, and all of the things that could make data BAD DATA. Good Data Bad Data

  18. Page 26, bottom half Conventions for Good Data

  19. Homework Complete “Certain and Uncertain Digits in Measurement Homework 2” on page 27 Certain and Uncertain Digits quiz on Day 1 of next week

  20. What is the length of the bug’s body segment?
