SQUID DISSECTION

This lab is a very thorough dissection of a squid and will be a great experience for our students. The understanding of the internal structure of invertebrates is not something students 'get' just because its not familiar. There are a few terms we need to be familiar with before we put Squidward under the knife.

arms

The squid has 8 arms attached to its head. They have suckers along the inner surface.

beak

The beak is located in the mouth of the squid, under its arms. The squid uses the beak to bite and tear its food.

cephalopod

Cephalopod means head-foot. It is the class of mollusks to which squid, octopus, nautilus and cuttlefish belong.

fins

Fins are the triangular folds on the mantle of the squid that balance and stabilize its body. The fins also can be used for movement.

ink

Ink is the substance that the squid expels from its body to protect itself from enemies. The ink confuses the enemy so that the squid can escape. The ink is stored in the ink sac.

jet propulsion

Squid move or propel themselves through the water like a rocket does. This is called jet propulsion.

mantle

The mantle is the muscula sac which contains the internal ogans of the squid.

mollusk

A mollusk is a soft-bodied invertebrate. The squid belong to the mollusk family.

pen

The pen is the internal shell of the squid

siphon

The siphon is a funnel-like organ through which the squid forces water to propel itself. By moving the siphon, the squid can move in any direction,

tentacles

The squid has 2 tentacles which it uses to catch its prey, They are longer and thinner than the 8 arms and the ends are covered with suckers.

Science Fair Reminders

OK there seems to be some confusion on what is due and when it is due. This Friday, April 29, a conclusion and graph are due. This means that your experiment must be complete but there is no need to bring your project to school or hand in your Final Report/Display Board yet. Conclusions and graphs can be on a sheet of notebook paper for this due date.

On May 10, FINAL REPORTS ARE DUE!!! Final Reports are to follow the check list that went home with the students last week.


On May 13, DISPLAY BOARDS are DUE!!! Display Boards are to also follow the check list that went home with students last week.




If you have any questions please feel free to leave them in the comment box, call the school, or email me!

Science Fair Help

I hope that all of your experiments are going well and that you are learning from the experience. Just wanted to remind you to record your observations in your science journals as soon as they happen. We all know humans are not perfect and our memory isn't the greatest, so record your observations!!! On Arpil 29th a graph and your conclusions are due. Chartgo is a great website to help you make that graph. Don't forget your titles and that you need to pick the type of graph that best expresses your data!!

Back into the Swing

Hope you all have had a wonderful spring break....only 7 WEEKS of School left!!! Sure has flown by, that's for sure! Testing begins next week, but we have some major events in class that need to be taken care of this week. Tomorrow is going to be an Open Response Day! Here's your hint.....Tectonic Plates: What are some changes that happen to the Earth's surface because of the plate movement? How does it happen?

Test is on Wednesday. Parent signatures on the study guide will be due as well.

Keep coming back for more info and events!!!

Just a Few Reminders

Hope everyone is having and fun and safe Spring Break. I just returned from Disney World with the High School softball team and had a blast...but life must go on and I just wanted to refresh your rested minds on what is coming up.

Monday: Review for Test
Tuesday: Open Response
Wednesday: Test
Thursday: Start Weathering and Erosion
Friday: Science Fair Check Point (Make sure you are recording your observations in your notebooks.
Display Boards will be on sale for $4.50 a piece.

Check this link out for information on collecting data and making observations.


SEE YA NEXT WEEK!

SPRInG BREAK!!!

Enjoy the week off! Spring break is an excellent time get caught up on the science fair.  If you have any questions post them in the comments for this post and I will do my best to respond. 

Science fair reminder!

Material list and procedures are due this Friday.  Science journals will be checked as well.
