There are many substances in your home of different levels of danger.

Your task is to determine which substances are acids and which substances are bases in your home and establish the strength (which is an indicator of the danger) of each acid or base.

                      

Points to consider       

	What is an acid and what is a base?
	How can you distinguish between an acid and a base?
	What is an indicator?
	How can the strength of each acid or base be determined?
	How do I use the materials that are required?
	Which acids and which bases can be potentially harmful to children?

You must test 20 substances from a range of areas around your home. The kitchen, bathroom, laundry, and garage are good places to start.

 

Present your findings in the summary sheet.  Plus a 150 word report on 4 substances in your home which are of the greatest potential danger for small children and why. Include in you report a diagram of the pH scale and write all the substances you tested alongside its pH level.
