October 18th - Food Webs

Today you will be completing a food web of a habitat you are familiar with.

Have fun and be creative!

Here is an example of an Arctic Food Web to help guide you.

Food Web Project

Directions: Create a food web for an ecosystem that is nearby. For example a

forest, stream, backyard, saltmarsh, or beach. You are encourage to choose an

ecosystem that you are familiar with. You should organize your food web so that

relationships between organisms are demonstrated (like we did in class).

Vocabulary to keep in mind:

organism

ecosystem

decomposer

food web

producer

consumer

trophic level

Required Items

Your food web should:

• have 15 - 20 organisms represented in the food web.
• identify the name of each organism.
• include arrows to indicate the flow of energy.
• have at least 2 of every trophic level represented (decomposer, producer, consumer).
• show many organisms interacting.
• contain a sketch for each organism.
• use a ruler to draw straight lines.
• contain color.
• contain a title (example - A Tidal Pool Food Web).
• contain your name and group.

Friday September 6th and Monday September 9th

We read an article on Asteroids and Dinosaurs which discussed good scientific practices and the study of how dinosaurs became extinct.  After we completed the reading as a class highlighting the main ideas in each paragraph the students were challenged to attempt some follow-up questions.

The final question was a constructed response.  We supplied the students with:
1. A product descriptor on a scientific constructed responses and
2. A rubric on how we assess scientific constructed responses.

The students have until Wednesday to make any changes to their responses.  Today we supplied them with anchor constructed responses showing them what a "meets" and "exceeds" looked like.
