But hey, what about that other side of science; Design and Make.


While reading over my posts and other things I have put together today, I realised I have barely touched on another side of teaching science and technology that is the Design and Make process.
This can be a very intimidating process for teachers to undertake with their students, not only because they feel that the sourcing and organisation of resources can be a major pain, but also that design and make tasks can be messy.

Well we can't do much about the mess except reinforce with our students that if they don't clean up after themselves they won't be able to do the work. Ensuring we leave enough time in a lesson to clean up and develop a clean up routine such as allocating two students to only focus on cleaning up one particular thing. They touch nothing else and if you allocate enough of those pairs of students, pretty soon your class will be cleaner than before you began.

Now for resources; When I began teaching science in my classroom I soon realised that I was going to need a lot of resources. As I was often teaching the same lessons to a whole stage I needed 120 of something at a time. So I had to collect, use things that were free and change my thinking. What was rubbish to me and my parent community could be a perfect design and make resource for my students.
So what did I collect:
«  take away food containers - great for storing students bits and pieces while a work is in progress. Great for mixed paint too.
«  bread bag tags 
«  plastic and metal bottle lids - milk bottle, glue lids, beer bottle tops,
«  snap lock bags
«  elastic bands
«  corks
«  paper clips
«  bread bags
«  paper towel rolls and toilet rolls (if your school allows)
«  dry pasta
«  used cds
«  used wrapping paper and scraps of material
«  ribbons
«  cardboard tubes that are on dry cleaners hangers
«  tissue and match boxes
«  paddle pop sticks and balloons
«  fruit netting bags
Your parent community may also work in places where there are offcuts or items that are regularly thrown away, but could be used by your students. Ask as you will never know what you will receive.
My general rule of thumb when collecting resources was; just because I can't imagine what the kids will do with it, doesn't mean it isn't useful.
Don't limit your students to your imagination and have fun with them. Often my lesson would consist of me sitting with a stanley knife cutting pipes, bending wires or cutting foam into the shapes my students wanted so they could turn them into fantastic new objects.
Lastly a word for the neat freak teachers out there; let go and enjoy your students using their creativity in a new way.

Starting with the basics; the processes we must follow.

For years of teaching elementary/primary school aged students, I struggled with how to create the best plans for students to best apply the investigating scientifically and design and make processes in my lessons.
Of course we have to start with the basics of what the two processes look like, then get into the nitty gritty of how to implement them in a classroom.

The process of Investigating Scientifically is as follows;




In part from the NSW Department of Education and Training 2005


This is the basis from which all science invesigations should be developed. Of course the level of complexity to which you teach it will be based on your grade level. For example I wouldn't teach a kindergarten student to write a hypothesis, but I certainly would ask them to make predictions and try to justify those to me. Any way we can encourage our students to think independently is great training for them.

When teaching science practically we are generally either teaching students to investigate scientifically or to design and make. 

The Design And Make process is as follows. 


This really gives students an opportunity to let their creative juices flow. Even from kindergarten they can be learning to identify an issue, create solutions for it, evaluate those solutions then make changes to their original ideas.

In the coming blogs I will be discussing how to create proformas for students to use in their science work when completing these processes and take a closer look at the meat and bones of a scientific investigation. We will look at 'fair testing', writing hypothesis and predictions and how students can collect information from which to base their results.
