Science Links for Homeschoolers- Emphasis on Shrimp Dissection

Science Demonstrations, density with flax seed and water;   Bernoulli’s Principle with a leaf blower and a beach ball.  Fun stuff showing real principles at work.

Huge collection of science websites of interest to learners and homeschoolers.

How to write a lab report

Anatomy comes from the word anatomae, which means dissection. Dissection is a good way to examine the structures, both internal and external, of an organism and discover how they work.

Dissecting a shrimp or a crawdad (we purchased our shrimp from the market): There are helpful youtube videos, but they are of limited use to me with my limited wifi, and I don’t want to use it hunting for the best of the videos.

Have the student write down or tell you everything he can think of that he knows about shrimp.

Observe some living shrimp.  Go to the pet store or a walmart and look in the aquariums. Visit an aquarium. Ask around among your friends, people at church, co-workers, and see if anybody has any aquarium shrimp.  Go tide-pooling. Go snorkeling. If your student is unable to observe a living shrimp or a crawdad, then don’t do this lesson. Do something he can see living in real life- an earthworm, a grasshopper, a fish.

Once you’ve observed a shrimp doing shrimpy stuff, write down everything you have observed and try to draw one.

The worksheets below come from this site.

Get your shrimp (or a crawdad) for dissecting.  You’ll need some kind of tray to put it on, gloves, a sharp pair of scissors, tweezers, and maybe lemon juice (you rub or splash it on the shrimp if the smell is too strong), and a magnifying glass or a microscope if you have one. An apron isn’t a bad idea. You can always just safety pin a beach towel- either bib-like, pinned in back, behind your neck, or safety pin each of the top two corners to the shoulders of your shirt.   Bleach the tray when you’re done.

Cut along the underside of the shrimp (use very sharp, small scissors), and make your incisision between the left

 

This simple worksheet has a drawing of a shrimp to label, a list of questions on observations- how many legs, how many this, etc, and instructions to find certain organs and draw them, and if possible examine with a microscope and draw what you see that way.

 

And answer key to the drawing- here it is with the proper labels.

This worksheet has a drawing of the internal organs and the parts are labeled.  It says it’s a diagram of cephalopods at the top of the page, but this is definitely a mistake. It’s unmistakably a shrimp, and shrimp are arthropods.

Marine ecosystems, shorelines

Marine ecosystems, coral reef

(both of the above links contain extremely simplified, dumbed down text. But you could use them as a basis for choosing what topics to explore further)

Coral Reef Life– fabulous pictures. Very helpful as a field guide, except not so much use ‘on the field,’ unless you bring a smart phone and a pocket wi-fi with you to the beach or on the boat.
