Creating a food web

Before I handed Air is Not Oxygen to the kids I was flipping through it, and it’s just like my favorite science books as a kid, there’s a sense of humor and it’s short fun lessons about different topics. Exactly the type of book I checked out from the library over and over again. I also had to laugh at the dedication:

Air is Not Oxygen is divided into subcategories by major science areas


reading Air is not oxygen

You’ve got all the major topics you’ll cover before high school, and I could see this making a fun homeschool co-op science class as you cover a different chapter each week and complete the extension activities. Since we’re studying biology I skipped ahead to that section and had fun reading through their food web section.

animal picture cards (I used these and a few others I had), yarn (I linked to red because I like red, in reality I used the yarn I had sitting in my craft supplies)


Food Web activity


We read the chapter about food webs, and learned animals are all connected together by the food they eat.


learning about the food web it starts off simple

First there’s plants, which are producers. That means they make their own food. I grabbed a piece of fabric to represents the plants. Then we found the first animal that eats plants and put a string from the animal to the grass.

Next we found another animal in the food chain, and attached it to the correct level, this one could eat the first animal.


food web all put together

Slowly we added more and more animals to our food web, and as we did we noticed a few things.


  • food webs are complex, very quickly we had yarn going back and forth between all sorts of animals and levels
  • taking out one animal does not destroy a food web necessarily
  • taking out more than one animal can destroy a food web as resources become less available
  • taking out several animals also can change how many of the lower level animals you have. We see this in Texas as most of the predators for deer are driven out, but the deer aren’t, and the deer multiply like crazy (that can’t be easily shown with this food web though)

It really was amazing how complex the food web grew, as I attempted to put away the pictures and the animals, I had yarn and animals everywhere.
