Assignment #4 - Food Webs

In Science, our class learned about food chains and food webs. We began by learning about simple food chains and what they are. Students read in their texts about what makes a food chain. Then we talked about examples of food chains that students knew of. I provided visuals on the board and arrows were also drawn to show the feeding relationships. I found a video clip on the internet that also taught the concepts and showed them this.

After that, we practiced making food chains with the food cards and arrows shown below. Students were to make simple food chains with at least three to four organisms using the information provided on the cards. They were to start with a producer and then find a primary and secondary consumer.

The next day, we moved on to food webs and talked about they represent all the feeding relationships within an ecosystem. The students then spent time using the cards and arrows to build a food web trying to use all the cards and arrows. The groups that sorted the organisms by food group (producers and type of consumers) were more successful at completing and displaying a more organized food web. Overall, they all showed understanding of food chains and food webs.
