Standard(s):
 1h.Students know most macromolecules (polysaccharides, nucleic acids,
proteins, lipids) in cells and organisms are synthesized from a small collection
of simple precursors
Objective(s):
 understand the structure of atoms in relation to building the molecules of
“life”.
Directions:
Part I. Atom Construction
1.) Open the following link:
http://www.classzone.com/cz/books/bio_09/book_home.htm?state=CA
2.) When the website is opened in your browser click on Animated Biology.
3.) Click on the far left-hand side of the screen and select Unit 1 Introduction. Then click
on Chapter 2 Atoms and Bonding.
4.) Use the component in the left frame to build different types of atoms.
5.) Create three different types of atoms and fill in the table below.
Table 1. Atom Construction

Part II. Bonding
1.) Click on the buttons on the left-hand side to make covalent and ionic bonds.
2.) Properly construct each type of bond between the atoms and capture a screen shot of
one covalent bond and one ionic bond.
3.) Insert the screenshots below and label them with the type of bond they are representing
(either covalent or ionic).
Part III. Answer the analysis questions below using the Classzone.com website and the
resources listed below.

What is the difference between covalent and ionic bonds?
Which particles are shared or transferred during bonding between atoms?
Where are protons and neutrons located in an atom?
How does the structure of atoms allow them to build the structures that create life?
