Last Time Matter- takes us space and has mass Matter is made of atoms Some matter is radioactive Matter that is radioactive has what is called a half life

Understanding chemistry can help us to solve (environmental) problems Bioremediation – Oil spills Oil spills – Heavy metal contamination Other uses of chemistry in the environment – Mine detection Mine detection – Renewable polymers – Tracking drug trade

So to solve problems…. …You have to know some chemistry

Remember the periodic table?

The periodic table includes things we should all be familiar with Oxygen Carbon Nitrogen Hydrogen These are the main types of atoms that make up biotic things.

The periodic table also contains atoms that are harmful to life Arsenic Lead Selenium Mercury Zinc Cadmium

Read “Letting Plants do the Dirty Work” Make a Bubble Map that describes what you learned about phytoremediation Use a green colored pencil to outline the circle if the describing bubble is a benefit of phytoremediation Use a red colored pencil to outline the circle if the describing bubble is a drawback of phytoremediation

Watch “Troubled Waters” Make a Sequencing Thinking Map of the steps the scientists used to develop a solution to their observed problem
