Coral Reef Worksheets and Interactive Notebook Activities

Coral Reef Worksheets & Activities

Corals and Coral Reefs Worksheets - Notebook Pages and Lapbook Activity

These new Corals and Coral Reef worksheets, notebook pages and the lapbook/interactive notebook activity have been added to our 100+page Ocean Unit.

In this part of our ocean unit, my daughter learned all about coral and coral reefs:

  • What is coral?
  • What do corals eat? (And what is the relationship between the algae, zooxanthellae, and corals.)
  • How does a coral colony begin? (coral reproduction)
  • What is a coral reef and where are they found?
  • What are the three main types of coral reefs?
  • What is the basic structure of a coral reef?

Here is a quick glance at the Coral Reef Notebook Pages.

There are fill-in-the-blank student coral reef worksheets as well as full (teacher) pages. If you prefer, your students can read the full-text pages provided (the answers are not highlighted so they can be used either way).

Coral Reef Notebook Pages - Worksheets

If your students enjoy interactive notebook pages, there is a set of coral reef lapbook pieces that covers the material as well. (There are suggested answers provided, but students can research and write in their own answers.)

Coral Reef - Lapbook - Interactive Notebook PagesThere are also a couple of activities that my daughter did with this section. She had to match the pictures of various types of corals to their photo & description.

She also did a notebook page on coral reef diversity and identified some of the sea life that can be found in coral reefs.

Worksheets - Types of Coral - Coral Reef LifeI have added this entire section to our Ocean Unit.  The Ocean Unit is now well over 100 pages.  Scroll down below to see what is included (and to see lots more pictures!)

Recommended Ages: We did this unit in middle school, but it can be adapted for ages 10-15 or so. My kids were ages 8, 10 and 13 when we first did this unit.  My youngest is now age 12 and she’s doing this unit again in middle school (since she was pretty young the first time we did the unit!).

  • Features of the Ocean Floor (trench, seamount, guyot, etc.)
  • Tides (and the Phases of the Moon)
  • Ocean Navigation (early navigation with astrolabes & the constellations, modern SONAR)
  • Salinity
  • Ocean Currents (Surface & Deep Sea Currents)
  • Ocean Life:
    • Special Body Features
    • Fish Body Shape and Movement
    • Biological Interactions: Mutualism and Commensalism in the Ocean
    • Deep Sea Life – Bioluminescence, Anglerfish
  • The Ocean Zones
  • There are lots of hands-on activity ideas included as well!

And now, a bit more detail about what is included in the 100+ Page Ocean Packet:

The last time we did this unit, we did a lot of hands-on activities.  I shared a lot of the details about our hands-on ocean activities, so I’ll just provide links to those (they are also included in the packet as well):
