The All about Oceans STEM 2 lesson plan has one content page. This page provides some very basic characteristics of oceans. Students will first learn that water is a necessity of life. Nearly three-quarters of the Earth is covered in water. Nearly all the water on Earth comes from the oceans around the world. However, ocean water is salt water. Because of this, it is not drinkable.

An ocean is an ecosystem. Of all the ecosystems in the world, the ocean has been explored the least. It is incredibly deep. Only recently have people been able to explore the depths. In fact, the greatest depth of the ocean is 36,198 feet deep! Lots of different life forms make the ocean their home. Scientists believe there are around a million species of animals in the ocean.

The lesson explains that almost 95% of oceanic animal species are invertebrates, meaning that they have no backbone. There are also huge animals like great white sharks, manta rays, dolphins, and sunfish. On the smaller side, there are many kinds of microscopic animals, too. They are only visible with the help of a microscope, such as zooplankton.


The All about Oceans STEM 2 lesson plan includes three worksheets: an activity worksheet, a practice worksheet, and a homework assignment. These worksheets will help students demonstrate what they learned throughout the lesson and reinforce the lesson concepts. The guide on the classroom procedure page outlines when to hand out each worksheet to your students.


The activity requires students to investigate the differences between two glasses of water. One glass will contain clean water with no additives while the other contains salt. The chart on the worksheet lists three questions for students to respond to regarding what they observe. Then they will respond to the prompts at the bottom of the page.


For the practice worksheet, students will color a map and list the oceans. They will answer the prompt asking them how many oceans are on Earth. There is a box at the bottom of the page in which they can write down the five oceans.


Students will create their own ocean animal or plant. In the big box, they will draw a picture of the life form they create. At the bottom of the page are three small boxes. Students must write out three characteristics or traits that the animal or plant has that helps it survive in the ocean. They will also need to an explanation for each trait.

Worksheet Answer Keys

There are answer keys for the practice and homework worksheets. Given the nature of the homework assignment, there are no actual answers provided. It reminds you to ensure students’ responses make sense and show comprehension of the content. If you choose to administer the lesson pages to your students via PDF, you will need to save a new file that omits these pages. Otherwise, you can simply print out the applicable pages and keep these as reference for yourself when grading assignments.
