Ocean Unit Freebies

Since I talked so much about the ocean yesterday, I thought I would share some of the ocean related freebies I made for our ocean unit last fall.  I hope someone finds these helpful.

Remember, crustaceans, arachnids and insects are all part of the arthropod group (look at this chart to see what I mean).  This is not a complete list of invertebrate groups, just some of the ones we studied last fall.

Here are some  Invertebrate Cards-Ocean I made when we were studying the ocean

We did an activity about the ocean zones. Visit that post here to find out more details:


Ocean Unit Resources: For this unit, we are using a number of books from the library, but the main spine for our unit is our large 100+ page Ocean Packet which will be available at some point soon. It is well over 100+ pages at this point and keeps growing as I add in this-and-that! It covers marine habitats, ocean zones, ocean features, tides and other topics.  :) ~Liesl
