Living Things and Their Habitats: Classification.

Starter

Last week you learnt more about the classification or vertebrates and invertebrates. Can you remember the characteristics of the animal classes? Test your knowledge with the challenge question. Refer back to last week or look in your Knowledge Organiser if you are unsure.  

Task 1

Today you are going to learn about microorganisms. These are very tiny living things, so small in fact they are not visible to the naked eye. Some of them are helpful; some of them are harmful. Look at the PowerPoint to find out more.

As you have seen on the PowerPoint, your task for today is an experiment.

 

You will need two pieces of bread (sliced white bread works best) and 2 plastic bags. Try and use a clear plastic bag, such as a sandwich bag, so you can observe the changes in the bread without having to open the bag. You should also label the bag with the variable so you know which slice it is.  

 

You can chose which variable you would like to do from the PowerPoint: light and dark; fridge and radiator; damp and dry; clean and dirty. If you wanted to, you could do all of the above factors and compare the results!

 

The experiment will last for around a week but it will depend on how quickly your mould grows. Make sure you have told an adult about your experiment and that you dispose carefully of your mouldy piece of bread.

Use the sheet below to record your experiment on or you could answer the questions/draw the table straight into your book.

I will complete the experiment too and post the results on the blog. Please share your results with us and we can compare the factors that makes mould grow!
