Today students started the day with a BrainPop about algae. Students learned about the adaptations of seaweed which include flexibility, gels to prevent drying out, air bladders to stay near the surface, and bad taste to keep snails from eating them.
Today students were responsible for making observations of seaweed, both fresh (thanks Mel and Carol for sending us some) and dried. I have a variety of brown algaes, but Mrs. R sent over some red seaweed for us to look at as well.
Students also made plankton observations using water from the pond behind the school. There were a variety of phytoplankton (green) and some zooplankton (mostly clear and moving). The zooplankton are usually around pond detritus because that's what they eat. On one slide we found a huge clear wormy plankton oozing and snaking its way through the detritus as it ate. It was so big I couldn't even put the microscope on the highest objective.
We finished class with the Plankton Grand Prix. We had a few more competitors and a couple redos. Many racers were disqualified because their plankton were floaters and the object was to sink slowly. Because of our imprecise time measurements, there is a three-way tie for third. Their plankton are pictured.
1 - Delafayette - Epic Flyer - 19.6 s
2 - Micheal - Spirit of Sinkyton - 4.5 s
3 - Noel - Noel Plankton - 4.18
Kaitlin - Four Eyes - 4.12
Jacob - Big Daddy Snorkelton - 4s
Eli-peezy and Joe Blow - both disqualified "floaters"
It is worthy to note that Nate tried out Life Wraft for a second time and in his second trial did outlast Delafayette's with a thirty second free fall. Here are some photos from class.

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.
Welcome!
Welcome to MsJ's Marine Ecology Blog. This blog is for parents and students to see what we are doing in class and for information on projects.
Orcas are very smart hunters. They hunt in packs to take down large prey like baby whales, sneak up on unsuspecting seals on the beach, and have been known to tip ice bergs to get at more seals.

COOL MOLLUSC
The slipper snail looks like a slipper if you turn it over and stick your toes under the covering. Slipper snails are also sometimes referred to as the Devil's toenails.
Odd Echinoderms
Sea cucumbers are echinoderms with a round oblong body shape. They are important detritus feeders. To learn more, watch the video.
