Ray’s Gr 5 Simple Machines unit.
Fall 11- under construction.- Feel free to help improve this! Can you speak another language? Let me know at ray.myrtle (at) I want to produce other language versions of the lessons so that ESL & parents with limited English can understand the material- some of this is just materials and ideas ‘parked here’.

Let me know so that you can tape another language version of
the lessons… Eventually I’ll post them here…
See version for my class that the students see at

Use the wagon as a simple machines quiz. (find the simple machines)- Didn’t work too well. Need a better one.

Content (What you need to include):

Include all the 5 parts of the scientific method:

1. Hypothesis: means: What do you think will happen?

You can also use a question: What are we trying to find?– for example: How far are paper clips from the fulcrum when the lever is balanced?

2. Materials: Exactly what things did you use? List them.

3. Method: (this part is optional) Describe EXACTLY how you did the experiment. Write out each step so someone could copy exactly what you did and get the same results as you did. Use diagrams to help make it clear.

4. Results: This is the measurements and other observations you made during the experiment.

  • the Data Table is the most important part. Include the results from other people in your class in your data table.

  • Put your data into a Graph. Label the graph.

5. Conclusions: Explain what happened. Looking at the results, what patterns do you see?

  • Errors: Why do you think we got different results sometimes? Why did Steven get 8 cm?What could explain it? Think about the way the experiment was done.

Give the three best 3 reasons why some results might be different.

Presentation (How your poster looks): See the examples on the board

  1. Titles and diagrams with felts – like a ‘sharpie’
  2. All words level on the page- no printing up or down, except on the side of the graph.
  3. Use a ruler to draw lines.
  4. Space out the parts of the poster so that it is not crowded or emply in any part.
  5. Put a box around each part of the scientific method (Question- Materials etc) so that the section is clear

Rubric: A chart that tells you how the poster will be evaluated and helps you know what to do.
Required– what you have to do.
Organization– The order of things or where you put things on the page so that the reader can easily understand what you did
Criteria: the ‘rules’ you have to follow for the poster

SIMPLE MACHINES UNIT Jan 2012, some updates 2014 & 15.- Ray Myrtle
Work with Ray to learn and share more about this unit in the ‘science group‘ at
This page is designed to be a revision of the Fall 2011 Simple Machines Unit.
Here is a link to a spreadsheet with a summary of all the Grade 5 Sc Outcomes((2008)1.xls
and open to the Science page, so you can get a quick check on what is expected.

Lesson 1- Graph the Class:

  • To learn how to put information into a graph and label it.
  • To learn to read a graph and make a conclusion.

Download the lesson description adapted from Ray’s ‘The First Week of School’ booklet: Graph The Class instructions for Simple Machines unit.doc

Download* the #2 & #3 blackline masters from here.
*FYI- The reason for the insistence on following the directions in the text (which might not be appropriate at other times), is that this excerpt is written to be used during the first week of school, when learning to complete a graph was NOT as important as the underlying goals for this activity: 1) to establish following directions,(if students don’t follow your directions during the first week, they never will!) 2). to quickly gain an assessment of students’ writing ability, and ability to infer.

Lesson 2- Static Friction Experiment watch the description of what to do here
The purposes of this lesson are:

  • to introduce the idea of friction, which will affect future experiments,
  • and do the experiment carefully in order to get reproducible results,
  • to learn record data and draw a labeled diagram of the results right away

Lesson #6 Inclined Plane Experiment

The purpose of this experiment is to illustrate about a key characteristic of simple machines: they change distance in to force.
We will find the difference in the amount of force needed to lift a weight straight up or lift it up on an inclined plane.
How to measure with a ruler (note start at 2:45 minutes- the part before that is about the imperial system.

Lesson #7 Inclined Plane Vocabulary

Lesson #8 2nd Inclined Plane Experiment- Changing the slope of the inclined plane

This experiment is an extension activity –
#8 Inclined Plane Exp.doc

  • to use data to make a prediction or hypothesis and test it.
  • to use data to analyse- eg how much does friction change the force on the inclined plane (if they had time to do the force on the flat)
    to provide an extension activity for those ready for it, and enable the teacher to focus upon those who need to work further on the first inclined plane experiment

I’m going to try to do a video on how to think about the ideas in this experiment. I’ve removed old #8 video.

Lesson #9 The Wedge

Lesson #10 The Screw

#11 Wheel and Axle:
The wheel is a wonderful invention that reduces friction. Usually in that case the wheel spins on the axle.
However when the wheel is FIXED to the axle it is can change distance into force.
Here is the vocabulary:

Note: one word is missing: circumference= the distance around a circle (the length of the outside)
Here is the video about the Wheel & Axle:
Here is a video about measuring with a ruler (use from 2:45- the early part is the imperial system.)
