My first science unit of the year is ecosystems, and I originally struggled a bit with this unit. I found plenty of materials, but I’m afraid that my students found some of the lessons to be a bit boring, which is the opposite of what I want. Science should be engaging and exciting for students. They should leave a science lesson feeling curious and intrigued, not bored. I made improving my science instruction my professional goal for the summer, and I feel much more prepared and knowledgable that I did last year. This post shares ten of my favorite ways to teach ecosystems, and I hope that you’ll find some of them useful.
I try to incorporate informational reading and science as often as possible. The books below are a few of my favorites. We use the books with interactive anchor charts like the one shown below where students write examples of producers, consumers, decomposers, herbivores, and carnivores on sticky notes and place the sticky note on the correct section of the anchor chart. I like to have different groups of students use different book, so that students are including animals from many different ecosystems.
Study Jams is such a great online resource! I show videos for my mini lesson all of the time, and they’re perfect for my standards! They are also short enough and interesting enough to keep my students’ attention. There are little quizzes students can take or individually as a class, and best of all-it’s free!
Ecosystem Accordion Books
Once my students have a good general understanding of ecosystems, I like to have them create simple ecosystem books. I have students fold a half sheet of construction paper into fourths. I like to cut large 12×18 construction paper in half, so students have a 6×18 sheet of paper. Then, students label each section with a different term for ecosystems. Students draw a picture of an example of each term on the booklet.
Have students create their own food chain. I provide students with a copy of the sun and five circles. Students draw a picture of a producer, something that gets their energy from the producer, and so on until all five circles include some plant or animal on the food chain. I like to start with food chains before I teach food webs, since these are much more basic for students.
I would LOVE to share some pictures of this activity, but I don’t like to post pictures with students, so I’ll just have to promise that this is an awesome activity! Give each student a card like the cards below and have everyone stand in a large circle. The student who has the card should stand in the middle of the circle with a ball of yard. Ask the student representing the sun to hold the end of the yarn tightly and toss the ball to someone who can use that energy (a green plant). When a student representing the green plant catches the ball of yarn, he or she should hold a piece of the yarn and throw the ball to someone else who could use the energy. After the yarn reaches a top level carnivore, cut it off to represent one food chain. Return the yarn to the sun to start another chain. Continue making chains until every student holds at least one strand of yarn. This is a great way to illustrate the difference between a food chain and a food web.
Food Chain Collage
I use crafts very sparingly, but I absolutely could not resist these food chain collages. It was so tempting to premake some templates for my students to use so everything could be nice and neat, but I wanted to give ownership to my students and to allow them to select any series of animals in a food chain.
Changes to Ecosystems Jigsaw
I haven’t had a lot of success with jigsaw activities in the past, so I was a bit hesitant to try it again, but I couldn’t keep ignoring the research. In this jigsaw activity was related to changes to ecosystems. Each group had five members, and then I split the five groups up into expert groups. My expert groups were: wildfire, logging, drought, pollution, and floods. My expert groups spent a few days researching and working on their presentations. Then they met back together with their original group to teach the group about what they learned. The surprising benefit to this was that a couple of my students who weren’t giving me good effort REALLY felt the need to step it up on the day they were to present. Most students chose to either make an anchor chart or a slide show for their presentation.
I love The Science Penguin’s Ecosystem Stations. I keep each station activity in a file folder. If the station requires cards, I keep the cards in sandwich bags in the folder. I love this resource, and I typically give students about three days to finish the booklet recording sheet.
Biomes are not technically in my science standards, but they lend themselves perfect to my ecosystem unit. An added benefit is that science is the one subject I don’t feel rushed to teach, so I have time for projects like this. I assign each student a biome: taiga, tundra, deciduous forest, tropical rainforest, desert, and grassland. Before beginning the poster, students will need to research their biome through books, videos, magazines, or online resources. Have students work individually or with a partner to create a biome poster on their assigned biome. The posters should include: attractive title and illustrations, biotic factors, abiotic factors, affects, and fun facts. The posters should be clear and easy to read, because students will participate in a study carousel to learn about the different biomes. Once all posters are finished, display them in the hallway or classroom. All students should then learn about each biome studied through the various posters. Give students a note taking sheet and have students take notes as they observe the different posters. As an optional extension, have students write feedback on sticky notes and place the feedback on the appropriate poster.
Build an Ecosystem
Naturally any lesson that includes LIVE FISH is sure to be a hit with students! To finish the unit, students got to build their own ecosystems. I didn’t try to have every student build an ecosystem. Although, that would be awesome. Since it was my first year teaching this lesson, I wanted to start small. I thought visual directions might be easier to understand, so I’ve included them below. Make sure to poke air holes for the fish.
We ended up giving our fish to our librarian who has a bit more sophisticated fish tank. white this “worked”, I didn’t want to leave the fish in a small space like that.
All of the lessons (except the science stations) are included in my Ecosystem Unit. The unit includes lesson plans, pictures, and all needed printables. However, even if you don’t use the unit, I hope some of these ideas can help your ecosystem unit!
