B.1.3.1: The body uses different types of muscular contractions to create movement and stability. Each type of contraction has a different function.
You go to the gym to do some strength training exercises. Make a list of at least 5 exercises you might perform.
We will then work through the B.1.3.1 Syllabus Understanding.
I will use my B.1.3.1 Lecture Notes as we discuss the concepts
Begin reading and taking notes on B.1.3, pages 281 - 292. Do NOT read beyond 281; that is HL content and this class is a Standard LevelĀ (SL) class. FYI, the handout given today on the structure of muscles is actually part of B.1.2. I felt you needed the background info.
This course is equivalent to a college level class. This assignment is not optional, it is an expectation of a student who wishes to find success at this level.
B.1.3.1āThe body uses different types of muscular contractions to create movement and stability. Each type of contraction has a different function.
Acetylcholine is a neurotransmitter stimulating skeletal muscle contraction.
Muscles are organized in functional groupings called motor units that contract using the all-or-none principle.
Muscular contraction requires the metabolism of ATP within the muscle cells.
Motor units are differentiated by fibre type and neuron diameter: types I, IIa and IIx. Their recruitment patterns vary depending on the activity.
Hypertrophy and atrophy of muscle can cause alterations in a motor unit recruitment pattern.
Contractions can be described in four different ways: isometric, isotonic concentric, isotonic eccentric and isokinetic.
Muscles usually function in pairs, and act with reciprocal inhibition: their pairings are agonist and antagonist.
No Bell Question, get into test-taking seats
Students will complete the Data Analysis Quiz
Once finished with the quiz, begin the Muscles & Bones Gizmos - given in Google Classroom.
Complete the Muscles & Bones Gizmos - given in Google Classroom
View the graphs below and then do the following with your table mates:
Determine statements that can be made about the data.
We will briefly discuss the Bell Question,
We will then discuss the Practicing T.Test assignment.
Students will then complete the Causation vs Correlation assignment, given in Google Classroom.
Once finished, we will discuss the difference between causation and correlation
Finish reading and taking notes on pages 138 - 146 (minus Components of Fitness) of the Old SEHS Textbook
We will have a quiz on Tuesday 2/10. Students will have to use a spreadsheet to:
Determine the mean and standard deviation of data sets
Determine the coefficient of variation within the data sets
Calculate the p value of data sets (T.test) and determine the importance of this p value.
Determine appropriate conclusions from the data
Graph the data, which will include titles and standard deviation (error) bars.
Image 1: Auto Fatalities vs Seat Belt Use
Image 2: Cycling & Safety
Open the T-Test Practice spreadsheet in the Performing T-Tests assignment, given in Google Classroom.
We will continue with the Video Practice portion of the assignment, which we began last class.
In the Google assignment, and here, is a link for T-test codes for Google Sheets
Use the codes in here to understand the order of commands and the numbers that represent tails and paired/unpaired)
Always use 3 for unpaired
Read and take notes on pages 138 - 146 (minus Components of Fitness) of the Old SEHS Textbook
Jaylen Brown's average points scored per game this season is 29.4 with a standard deviation of 7.6.
Within how many standard deviations does his 1/5 and 1/17 scores fall? See the 1/26 agenda for scores.
Last year Jaylen Brown averaged 22.2 points with a standard deviation of 8.9.
What can you determine about his 2025/26 scoring performance when compared to his 2024/25 performance.
We will discuss the Bell Questions and any questions you might have had about the graphing assignment.
We will then model an IA research question and data collection, which will lead to the need for statistical analysis
To better understand statistical significance students will watch a tutorial on how to perform T-tests and complete .
While watching the video, I will stop the video and students will practice along with the narrator.
The spreadsheet has a Video Practice tab with all of the problems in the video. Students will just have to calculate the p value

Video 1: Performing T-tests for Beginners
Open the 2021 Super Bowl and Standard Deviation assignment in Google Classroom
Open the Google Doc
We will discuss Tables 1 - 4 , the spreadsheet and Step 5 of 2021 Super Bowl and Standard Deviation assignment.
Students will work through the Analysis Questions
We will then discuss how to graph our data and add standard deviation bars to a graph.
You will need to take notes on this
We will then discuss the Graphing Super Bowl Data assignment, given in Google Classroom.
Students will have the rest of the block to work onĀ
the Graphing Super Bowl Data assignment, given in Google Classroom
Complete the Graphing Super Bowl Data assignment, given in Google Classroom.
Read and take notes on pages 138 - 146 (minus Components of Fitness) of the Old SEHS Textbook
Image 1 has the points scored by Jaylen Brown (of the Celtics) for each of the last 10 games in which he played?
Were the points he scored on January 5th and the 17th unusual or within his expected range of scores?
How do you know?
How can you verify?
We will start class by discussing Standard Deviation
Students will then open the 2024 Super Bowl and Standard Deviation assignment in Google Classroom
Open the Google Doc
We will work through Steps 1 through 3 of the assignment as a whole group
Students will then have the remainder of the assignment to complete individually
What ever does not get completed in class will be homework.
Complete the first four tables of the 2021 Super Bowl and Standard Deviation assignment
Neither the Google Doc nor the Google Sheet need to be submitted, we will complete them in class.
