We had a really small group in class this week, but it worked out okay with the activities planned. We talked a little about food webs: producers (the organisms that can make their own food--plants!) and consumers (the ones that eat the plants, and each other). Then, half the group worked with an interactive food web situation on Gizmos while the other half chose an animal from the coastal region to research. After 30 minutes, they switched. The food web activity let the students manipulate the populations of organisms in a simple food chain and then see the effect over time. After playing around with it for a few minutes, they made predictions and then recorded the results after testing them. It was a good demonstration of how key each organism is to the survival of all the others. Each student chose from a list of animals that could be found in the tide pools or nearby area--sea anemones, limpets, hermit crab, seals. They spent time in class creating a poster with facts about their animal's habitat and personal food chain--what they eat and what eats them. They also drew a picture and were given a homework assignment to either copy that picture or create a 3-D representation of their animal for our class food web that we will create next week.

Activities: Animal Adaptation Poster This link is to the poster we are creating for our animals. If you have an animal lover, let them make these for a variety of animals--maybe all the animals to show a food web, or covering animals that you encounter throughout the year. Peruvian Food Chain Jenga This looks like an awesome way to look at food chains, and have fun at the same time. What demonstrates the delicate balance with an ecosystem better than Jenga?
