In our unit 'Changing Materials' we were just about to carry out our investigations involving dissolving. If you have some salt or sugar at home, you could try some practical activities involving dissolving. You MUST ask your parents first and only carry out any practical activities with their permission.

If you wish to, you could try some of the independent variables that we discussed in class (in the document below). If you can remember the investigation question that your group decided on, you could try that also.

If you are unable to carry out any practical work, you could investigate some key scientists who made great discoveries with their work with materials. Two scientists of interest are Arthur Fry and Ruth Benerito.

When researching, consider the following:

• interesting details about their lives
• what their main discoveries were
• any other discoveries/inventions of interest

You can present your research in any format that you wish.
