This week in science, we have set up an investigation into where the most bacteria is found. We have extracted bacteria from five different locations in school (the toilet, sink, fridge, door handle and a hand). We are going to leave the samples of bacteria to grow and re-visit our investigation in science next week!
Where do you think the most bacteria will be found? Why? (Can you link your explanation to scientific knowledge?)
What is the independent variable in the investigation?
What is the dependent variable in the investigation? (Some of you may need to look up these key words)
I am looking forward to hearing your predictions!
