Plankton Nekton Benthos Review
Because of the law of 10%, there are often tens of thousands of plants needed to inderectly support a top predator because the plants feed an herbivore, which feeds a consumer or two or three before reaching the top consumer. At each step, ninety percent of energy is lost or consumed and only ten percent is stored in tissues.
To review plankton, nekton, and benthos, students participated in a scooter relay sorting organisms into the categories.
Plankton = floating or drifting lifestyle
Nekton = swimming
Benthos = bottom dweller - attached or crawling
Everyone had to participate once... some folks were really into it like Brandon and Rick. Both teams ended up tied with one mistake - baby fish. I asked a representative from each time where they would put baby fish besides nekton, and Rick and the right side team correctly answered plankton. They received stickers for winning. After all the excitement, students finished the day by working on a food web worksheet.
Computer Lab Etiquette
You are in the computer lab to do work for this class. If you are not doing work, then we will have problems.
Do not pack up early. Work until the bell or until MsJ says.
SAVE OFTEN. And if you save to a key, also save it to your number. If you lose it, you will have to do it again.
If MsJ asks for your attention, stop what you are doing and listen to what she has to say.
You may watch videos about your organism through reliable websites.
You may listen to music through the computer if you have your own headphones. Rule1 MsJ cannot hear it. You get one warning. Rule2 Turn it on and listen – no million clicks and constant changing. Take both ear phones out when MsJ is talking.
Goal 1. Finish your trading card. If you think you are finished, re-read the blue sheet and the boxes on the side of the card and make sure you have answered every question completely. Be sure that everything is in your own words and not copied and pasted.
Goal 2. Get your card proofread and proofread others. Can you make your card better? If you are sure you are done, email your card as an attachment to email@example.com Please put your name in the email or as the subject.
Goal 3. Help others proofread. If you are all done, check out some of the links in the blog entries below. Play free-rice (a MsJ fav). Be a citizen scientist and help out Snapshot Serengeti (a fav of mine), Seafloor Explorer, watch worms, analyze cancer, and others! If you would like to be doing something else while on a computer, please ask.
Really Good Resources - Ask MsJ if you need help finding resources.
