Great Lesson

It'd be awesome to post some actual footage of this lesson being done. Any takers? I'd like to see pros/cons and good/bad and what you reflected on as you finished the lesson.

This is a unique, rich,

This is a unique, rich, constructive lesson. I really like the intent of the lesson comparing the life cycle of animals and product. I modified the lesson but kept the integrity of the lesson. As an activator I use a short clip from "How Things are Made" and another clip from Journey North on the life cycle of a butterfly. My second grade students and I discussed and recorded what we know about butterflies. I asked the students if they agreed with a posted statement if goods (products) also have life cycles? Most of the students stated no, which was what I expected. I did not address or implement the worksheet but as I stated before the integrity of the lesson stayed in the forefront of my objectives. Moreover, I added several book resources that provided discussion points, background knowledge, and comparison sources of life cycles. The books may be too elementary for seventh graders, but sometimes simple is better. Anyway, I used several books from a series called Start to Finish by Shannon Zemlicka, "From Rock to Road," "From Wheat to Bread," "From Sea to Salt," "From Milk to Ice Cream," From Tree to Paper," "From Sheep to Sweater," and four books from a series titled "Materials, Materials, Materials Wool" and "Materials, Materials, Materials Glass" by Chris Oxlade. I intend to implement the lesson again with modifications. I want to spend more time on the construction of products. However, at the end of the session, which in the future I plan to expand to several days, my second graders wrote the close "I used to think but now I know" and stated that yes, products have life cycles. In fact, since the lesson, which was over one month ago, my students are stating that this product has a cycle!

This is a fun lesson. I

This is a fun lesson. I really like the way it connects the products life cycle to living things life cycle. You could open it up to have each group come up with (or research) the life cycle of an animal or plant from a different ecosystem or biome to increase variety in their answers.

Great lesson. Gives students

Great lesson. Gives students a good insight into how a product is produced and whether the product has large or small impact on the environment. Remember to make the students separate the physical products and examine them.
