Social Studies - Heritage (Canada’s First Peoples)
Knowledge Objectives
Students will know that:
- First Nations peoples have been living in what is now called Canada for tens of thousands of years.
- First Nations peoples developed technologies to meet their needs.
there is great diversity among First Nations peoples
Teacher Set Up
- Using the coloured tape, mark off a throw line. Make sure there is ample space for students to throw the dart.
- About 10 metres from the throw line, place a pylon so the students have something to aim at, you may have to adjust target placement depending on your students.
Student Instructions
Background Information
- Research pre-contact and post-contact technology for a Canadian First Nation group. As a class, create a timeline of Canadian First Nations’ technology using the approximate time period it was used or invented.
- Discuss the similarities and differences in the atlatl and dart from region to region.
- After your teacher demonstrates how to use the atlatl, try it yourself.
Maximum Distance & Speed
- Decide on 3 or 4 students from the class to throw. Record the distance and time traveled for each length.
- From the line, each person throws the dart 5 times without using the atlatl, aiming at the pylon.
- Measure each throw from the line to see how far the dart traveled.
- Record the distance and time the dart traveled for each person.
- Repeat steps 2-4 with the atlatl.
Data Analysis
- Calculate the speed for each throw
- Determine which the maximum distance with and without the atlatl for each thrower.
- Determine the maximum speed (v=d/t) for each thrower
- Compare the results with and without atlatl graphically by choosing the appropriate graph type
- Determine whether the dart went farther and faster with or without the use of the atlatl. Think of some ideas why.
- List the advantages and disadvantages of the atlatl comparing them to the technology previously researched.
Closure
As a class:
- Discuss factors that may have distorted the results of the data collection.
- Consider how the nature of the sample, method of collection and sample size could be refined to find more precise results.
