Simple Machines – Unit Brief
(Carmel Denniss and Michele Williams, St Charles School)
What is a machine? How do machines move? Where do we use machines in our everyday life? Why?
Pre-test to gain understanding of students prior knowledge
Students (partners) to explore http://www.mikids.com/Smachines.htm . Students read definition of each type of machine and explore the examples provided.
Show students the film “COG” and then a slideshow on different types of machines (complex and simple). http://video.google.com/videosearch?q=Honda-Cogs+Accord+Ad&www_google_domain=www.google.com&emb=0&aq=f#
Students given examples of simple machines, and asked to in terms or purpose, design, etc
Sort and classify simple machine images
With a partner explore Edheads ‘Simple Machines’ website site. Students explore each of the four rooms in the house to find the 10 simple machines in each room. http://www.edheads.org/activities/simple-machines/

Excursion to Luna Park – observe simple machines in action. Draw and take photos of the simple machines in each ride.
Luna Park Art Response – Children select a ride from the ‘box’ to paint and label
ICT: Use Luna Park images and imovie (Apple Mac) to begin to create a Luna Park movie. Include free talk and oral descriptions/poetry.
Simple machine stations. Small groups to work in different activities (research, experimentation and play using each simple machine, website exploration)
Literacy: Students to write a procedural recount for one of their experimentation sessions
How do we design a ride using simple machines? How do I evaluate the effectiveness of my design? How will I test and retest to make sure my design is effective?
Children to design a model of a ride that uses at least 2 simple machines in its design eg an inclined plane and a lever.
Designs discussed and modifications suggested by peers changes to be made in final design drawing -on A3 paper- include a list of materials needed on side of sketch. Detach list from design and take home.
All-day design and make
10 minute writing topics as follow up/ reflection topics
1. How did you feel about your design and make task/day?
2. Did you manage to recreate your design exactly as you planned?3. Did you fulfil the design brief by using as many simple machines as you thought you would?
