SOME GOOD FUN….

Part A:

Go to



• Click through the tutorial until you have covered all concepts 1-6.

• This is an excellent tutorial. Allow yourself to make the most of it and let it “tutor” you on macromolecules!! So that actually means…go through every page and read it.

• Take the “self-quiz” at the end.

On back page of handout, write a reflection about this website and explain three specific things that you learned.

Title this “Internet A Reflection”

Part B:

Go to



Click on “Go to Activity” (the computer may ask to “allow” access, if so…”allow” it)

Read first general prompt and then click “next”

Read prompt about polymers and then click “next”

“Zoom” (by clicking) on ALL organisms in/around Tree of LIfe.

• Leaves

• Parrot

• Bee

• Spider web

• Monkey

• Iguana

• Syrup

• Frog

• Worm

• Bacteria

• Human

You will do this “zoom” many times on each organism. You will click on actual icon on tree, then again to cellular level, and then click on the blue highlighted in molecular level, and still even further. JUST KEEP CLICKING until you can’t go any further. Read the tutorials about each one.

Now, test yourself! Go answer all the questions in part a, b, c, d, e.

On the back of the handout, write a reflection about this website and explain three specific things that you learned. AND ALSO…in your own words, explain how monomers and polymers are connected.

Title this “Internet B Reflection”.
