Grade 8: Science: Simple Machines

Instructional Design: Sue McIver

Stage 1 - Desired Results

Established Goals:
Specific Outcomes:

*Describe simple machines and learn how they are used in everyday life

* Define mechanical advantage and create a problem to find mechanical advantages.

ICT Outcomes:
Below is a pdf file identifying all of the ICT outcomes touched on throughout this project. Click on the file to download it to your computer.

General Outcomes:
•Understand how and why simple machines are used.
•Understand how to calculate the mechanical advantage of simple machines.   

Essential Questions:
•How do simple machines create a mechanical advantage. (use a formula)?
•How are simple machines used in everyday life?

Students will know:
•vocabulary of simple machines.
•formula for calculating mechanical advantage.
•general awareness from reading from text as a class.

Students will be able to:
•show visually how each simple machine works and how to calculate mechanical advantage.
•show visually how simple machines are used in everyday life.

Stage 2 - Assessment Evidence

Performance Task(s)
The students will have at least 5 visual representations of their simple machines with answers to each of the following questions:
•Define your simple machine
•How do simple machines create a mechanical advantage (use formula)?
•Create a question involving mechanical advantage
•How are simple machines used in everyday life?
•This Power Point must be a minimum of 8 slides with a maximum of 12 slides.

Other Evidence (Quizzes, test, etc)
•Some students can add additional pictures, animation, and sound.

Self Assessment
•Students will have a rubric available to fulfil outcomes.

Stage 3 - Learning Plan

Teaching and Learning Activities

Simple Machines Project- Sc 8  Planning

To do in class, before first period in lab:
Assign topic (machine type) to each student.
Provide students with rubric and explain task with expectations, including timeline.
Have students research topic. Talk about plagiarism and need to write in own words.
Have them keep track of references for bibliography.
Look for pictures on Internet (www.google.com---images is always an easy way to find pictures)
*Remind students to record picture site

Period 1 in lab: Review of Power Point and start on presentation:
Show example with advice
Review: New slide, Text box, View all slides, Add pictures, add and view notes. Provide students with Power Point reference notes.
Let them start their presentation, concentrating on getting the text on the slides.

Period 2 in lab: Continue to work on Power Point presentation:
Review how to do animation, talk about sounds.
Let students work on their presentation and finish gathering pictures.

Period 3 in lab: Finish PP presentation:
Let students finish their presentation. Print if they have notes.
Practice for oral presentation. Start viewing presentations as teacher evaluates using rubric.

To do after both lab periods:
Have students present their oral presentation and mark finished product using the rubric.
Students could mark each other while watching presentations and/or have them answer prepapared questions by presenter.

Key Design Elements

How will students know where they are going, why they are headed there, and how they will be evaluated?

They will have a rubric and assignment will be given to them.

How will you hook the students at the beginning of the unit?

Using the computer to visually display info with graphics.

What will help students experience the big idea of this unit?  How will you equip them with the needed skills and knowledge?

Reading and discussing text as a class. Providing examples.  We will teach them the power point skills required.

How will you get students to reflect and rethink?  How will you guide them in rehearsing, revising, and  refining their work?

Giving feedback on their project.  Referring to their rubric.

How will students exhibit and self-evaluate their growing skills, knowledge and understanding?

Using their rubric and fulfilling the requirements.

Additional Teacher Resources
These are documents for teachers and/or students that were developed to support the project.  Documents will always be available in pdf format as well as in the original format created (e.g. MS Word, AppleWorks, Inspiration, etc)
