Discuss how marine animals are affected by plastic waste that doesn't get recycled or disposed of correctly and submit here.
Discovering Plastic Properties (like specific gravity & buoyancy)
Which plastic types will float or sink in fresh water and/or sea water?
Density and buoyancy of disposable plastic products can be found using simulations of local marine zones. Use these marine baths to show how plastic properties are related to their effect on different habitats.
1. In lab groups, test whether your plastic trash will sink or float.
2. Then, test and compare two plastic types in both water baths. 3. Fill the Sink or Float table and discuss the results.4. Start writing the chemical names and formulas for the types of plastics you found in your Plastics and Their Uses table.

For example, if I put 4 protons and 5 neutrons in my nucleus, I made a Be-9 isotope.
Isotope atomic number neutrons protons electrons atomic mass

Continue this activity for 15 more isotopes.
Modeling Activity
Sketch the "hybridized" Bohr model shown above. Which isotope and/ion does it represent (red-protons & green-neutrons)?
Demo: In the picture above the second orbital represents a hybrid (or merger) of 2 2s outer electrons (or 2s2) and 2 2p (or 2p2) electrons. The innermost orbital, 1s, is not part of this hybridization and can only hold up to two electrons represented (or 1s2). This can continue until all the 2p electrons are used up.
Then make a third hybrid outer orbital for the 3s and 3p electrons.
In teams: Make a similar model for an assigned isotope from atoms 1-20.
