Poster design extra credit

Here's the extra credit opportunity for the 3rd 9-weeks.

You can design an educational poster. The poster is worth up to 30 assignment points. Plus, within each category and topic I will select a 1st place winner to receive an additional 20 test points.

There will be two categories for posters: 1) mixed media, and 2) traditional poster
The traditional poster category will include posters with only 2-dimensional graphics. The mixed media category can include 3-dimensional art and other techniques beyond colors and pictures.

For the topic, you can choose any one of the following:
scientific thinking/scientific method (ch 1)
biochemistry (ch 2)
the biosphere (ch 3)
ecosystems and communities (ch 4)
populations (ch 5)
humans in the biosphere (ch 6)
cells (ch 7)
photosynthesis (ch 8)
cell division (ch 10)
heredity (ch 11)
DNA (ch 12)

There are 11 topics multiplies by 2 categories, so there could be 22 1st-place winners. You can enter up to three posters.

Do not simply steal a design off the internet. If you are found to have stolen a design from someone else, you will receive no points.

Put your name and the topic on the back of each poster. The posters are due by April 1.
