Welcome to another year in English as an Additional Language (EAL) at AISB. This year, I’m working with Grade 4 and grade 5, so I am lucky to continue working with some of my students from last year.
For the first six weeks, we have all been busy settling back into school routines and have completed our first unit of inquiry. The unit in Grade 5 was under the Sharing the Planet transdisciplinary theme. They were inquiring into resources around the world, specifically energy resources. We decided to inquire into solar energy in EAL class and I challenged them to cook an egg using only the sun.
They started writing down what they knew about solar energy and then we used various websites and on-line books to research solar energy and its various uses. The children learned about solar panels and solar ovens. Initially, they came up with various solar oven designs, based on their prior knowledge.
Here is Anna’s initial prototype, made out of clay.
After they went home and continued to research ‘solar ovens’ by talking with parents and searching on the web, their initial designs changed. Yeonatan came in with his prototype oven, and Anita and Anelise arrived with their oven half-built.
Once they wrote their plan and built their solar oven, they took their devices outside. Luckily, it was an extremely sunny day. Each of the box ovens had one whole egg (still in the shell) and two s’mores. I decided that even if the egg worked, melted chocolate with marshmallow was going to be more exciting (and tasty) for the students than a (potentially) cooked egg!

The four devices – you can see the reflecting happening already…
We put the devices outside at 9:00 a.m. They drew lots of attention from other students during recess and the fifth graders constantly ran over to change the position of the ovens depending on where the sun was. They later informed me in class that they were not only changing the position, they were also moving the lid up or down depending on the position of the sun. What great scientists!

Checking on progress… “Ms. Erika, the chocolate is starting to melt!”
6 hours later…
The first ones to open the oven are Anita and Anelise. They didn’t want to wait any longer so they decided to eat one each of the s’mores and check the egg. At this point, the sun was behind the school and the oven had been in the shade for the past hour or so.
THE EGG WAS COOKED!

The results varied depending on the oven. It was an incredible inquiry.
