Cows Moo Softly - Variables in Science

When teaching science I try very hard to make sure that we are truly doing science and not just another English lesson with a Science theme. I also try to help my students to make connections with the scientific process we are using by using a similar format (question - hypothesis - method - results - conclusion).
I introduce scientific words in context as I think my students are ready for this. They love the big words!
One of the important scientific ideas is setting up a fair test. In order to do this children need to begin to understand variables and how we can control these when we are doing a test.
Cows Moo Softly is a mnemonic for Change - Measure - Stay the Same and is easier for my students to grasp than "independent variables" and "dependent variables".
I have made some new charts that can be used to help kids to think about variables when they are doing science.

There are some that can be printed onto coloured paper and laminated to use as class signs. I pin this type of sign to my board (using blu-tac or magnets) and write next to it. That way I can reuse them over and over and my board work is a bit more pleasing to look at than my own scribble writing.
I have also squeezed the three parts onto one page that could be photocopied and used for individuals or groups to plan their experiment.
If you would like these files for your room, you can download them for free from my TPT store.

The cow is by Scrappin' Doodles - isn't she cute?


  1. Computer Science
    Computer is an electronics device that can accept data and instructions as input, process the data to given instructions and shows results as output. Computer also has ability to store data and instructions. The physical and tangible parts of the computer are called “Hardware”. “Software’s” are intangible parts of the computer system.
