Science- LO: To investigate how sugar can affect human teeth.
Tooth enamel is tough but can be eroded by sugar in your beverages and acids in your mouth. Sugary beverages are not good for teeth as they stick to the surface and bacteria then break down the sugar to make acid, which can damage teeth. When tooth enamel is exposed to acidic beverages or acid generated by sugary beverages, it softens and loses some of its mineral content. Saliva helps neutralize the acid, restore the mouth's natural pH balance, and slowly harden the tooth enamel again. However, because the tooth's recovery process is slow, if the acid exposure happens frequently, the tooth enamel does not have the chance to repair. This can cause tooth sensitivity and lead to the need for dental treatment to protect the tooth and the dentin underneath.

- Look at the sheet called Tooth Decay, Scientific Enquiry. You’re going to need some different drinks, cups and eggs (white ones might be better as they are more ‘teeth’ coloured).
- Decide what your question is going to be. It could be something like….’Which drinks causes the least amount of decay?’ or ‘What happens to enamel when you drink a sugary/caffeinated drink?
- Make your predictions.
- Think about what you will keep the same and what will change. This will ensure you have a fair test.
- Begin the experiment. It might be useful to take photographs.
- Record your results.
- Write what you found out.
You could put toothpaste on one half of your egg to see if toothpaste really does protect the enamel on your teeth.
Send your complete work, including any photographs to your teacher.

Think…….. Write down 3 things you believe to be true. For example you could say:
I believe that, if I try hard, I will succeed.
I believe that people don’t always tell the truth.
I believe that things online aren’t always true.
Can you think of something you believed in when you were 5 or 6 that you now don’t believe in?

Reread Aiden’s story from last week’s lesson. Can you imagine what Aiden believed in when he was 5 or 6. Do you think he would have reacted differently in the same situation? What about it Aiden was 20. What do you think he would believe in then and how would he have behaved?
Use a dictionary you might have at home, or search using a search engine the word assertive. What does it mean? Can you think of some examples when you have been assertive?
Read this scenario:
Ella-May and Jackson have had an argument with a friend called Maxine. Maxine borrowed something that belonged to Ella-May and lost it. Ella-May got angry with her. After the argument, Maxine posted untrue and unkind things about Ella-May on Instagram, Snapchat, Twitter and Facebook. Now Ella-May wants to post unkind things about Maxine to ‘get her back’. Ella-May’s friends don’t like Maxine and are really pushing her to do it. They have said they would comment on any posts about Maxine so she knows that nobody likes her. Jackson is Ella-May’s younger brother and he isn’t so sure this is the right thing to do.
Write Ella and Jackson some instructions about how they could be more assertive in this situation. If there is someone at home who can help why don’t you act it out? One of you can be Ella-May and the other can be Jackson or Maxine. Maybe you could use some toys to be the other characters.
