===Description of activity===

{{Actividad|los estudiantes aprenderán las cadenas tróficas y sus niveles}}
−
First the teacher will explain the 5 trophic levels of a food chain to the students using the hand out with the sample food chain (Figure 1).  Then once they have learned about trophic levels, autotrophs, and heterotrophs, each student can begin looking through the magazines and cutting out pictures of animals to create their own food chain. Once each student has completed his or her food chain, you can have them share them with the group.

===Descripción de la actividad===

En primer lugar el profesor explica los cinco niveles tróficos de una cadena alimenticia a sus alumnos usando un papelografo con un cadena alimenticia típica (lámina adj.) Luego que han logrado un conocimiento de niveles tróficos, autotrofos y heterotrofos, cada estudiante mirará en sus revistas y recortará las imagenes de animales para elaborar su propia cadena alimenticia. Luego de terminado su trabajo la comparte con el grupo.

Once you have covered a simple food chain or web you may continue the lesson by talking about different relationship between animals other than predator and prey situations.  For instance relationships that benefit both organisms could be explored.

This lesson was very interesting for us to do because it produced many questions by the students that also challenged us.  One of the questions that was asked numerous times was whether or not elephants eat other animals like a monkey or something along those lines.  The challenge was not in the answer here but rather once we told them that they did not and that they only eat leaves and smaller things, they wanted to know how elephants got so big if all they ate were plants.  This was a challenge for us to explain to them.  It was also interesting to see how some students took the initiative to make their food webs very complex while others barely finished the bear minimum.  We were a little pressed for time though I feel like a half an hour would have been sufficient but only twenty minutes was a little more difficult.

We have recently received feedback from the classroom teacher that we work with on the lesson and she has told us that having the list of vocabulary was crucial to the project itself.  She said that many times, students just need the confidence of having the words next to the to look at whenever they need to rather than constantly having to ask how to spell something.  Many students may not be confident in themselves or are too shy to ask in the fir
