LO: 1) To plan and carry out oxidation investigations

          2) To observe and record oxidation reactions over time

Science home learning 18.6.20

This week, we are back to our chemistry learning and we are exploring OXIDATION. Some changes in materials can’t be reversed and they can produce new materials in the process. Immerse yourself in the world of oxidation and observe how rust is formed and how apples spoil when cut open – can you prolong your apple’s shelf life or is it all looking brown?

The first attachment is a list of enquiries about nails.  You may choose which one you want to do.  Then use the following attachment to guide you in the process of setting up a fair test, predicting and collecting results.

Present your findings in your preferred way, ensuring you have answered the question you set out to answer!  The results will need to be taken over a period of time – 1 week should be enough, but you can extend to 2 weeks if no real changes occur quickly. 

There is an extra challenge, but it is one you can set up quickly and easily alongside the nails as you should see some changes pretty quickly.

First, follow the links below to brush up your thoughts on rust:


Once the rust investigation is set up, investigate another oxidation reaction – why do apples go brown when the flesh is exposed to the air?

 Chop an apple and investigate the impact of various other materials (sugar, lemon juice, salt, crushed vitamin C tablets or whatever you have handy!) on the rate of oxidation (include a control). How will you measure and record the changes? Try to devise a table and use photographs for comparison across materials as well as across time.  Use the nails investigation sheets to help you plan your test.
