Solar Oven STEM: Engineering Design Challenge


When I was teaching science my 6th graders would end each year engineering their own solar oven. It was always a big hit. This is a great activity that is certainly not limited to middle school. Anyone with some creativity and building skills can tackle it!

What is a solar oven?
In many places around the world, solar ovens are used to cook food with the sun. In North America, they are mostly used for camping, solar oven cooking groups and hobbyists. If you have an effective solar oven, you can cook just about anything you'd cook in a regular oven. For this design challenge, I'd recommend cooking something that can be cooked without too much concern over spoilage. S'mores, nachos, English muffin pizzas, etc. are good kid-friendly choices to start out.

The Challenge:
Build a solar oven that effectively "cooks" your desired item. The #1 rule is: do not search for solar oven designs on the internet! Creativity and your own ingenuity will take you far with this one!

Possible Materials:
(This list can obviously be tweaked as you see fit, however these materials have been chosen for safety, and age appropriate degree of challenge.)
  • Aluminum foil
  • Cardboard
  • White office paper
  • Tape
  • Packing peanuts
  • Newspaper
  • Black paper
  • Plastic Wrap
  • Glue
  • Scissors
**NO: glass, magnifying glasses or sheet metal**

Science Ideas to Consider:

3 Types of Heat Transfer:

Convection- You've probably heard that "heat rises". Convection is the science term for this phenomena. Convection is the movement of a fluid (air or liquid) where hotter and less dense material rises, and cooler, more dense material sinks. We experience convection when heating our homes, when swimming in a large body of water, and in convection ovens, just to name a few examples.
  • When building your oven, imagine that heat will rise. How can you get the heated air to stay close to what you want to cook?

Conduction- Conduction is when heat is transferred directly from one objects to another when they are touching one another. Some materials conduct heat more easily. A good example is when you leave a metal spoon in a mug of hot cocoa. If it has been a few minutes, you'll notice when you touch the spoon again, it is very hot. It has conducted heat directly from the hot liquid. Conduction is what heats something that you put on the stove. The pan is directly touching the hot stove, therefore its contents are heated up.
  • When you design your oven, will the cooking surface conduct heat?

Thermal Radiation- Thermal radiation does not require direct contact. Heat travels in waves from one source to another through air, or another substance. Heat from the sun is the best example of thermal radiation. The sun is not directly touching what it heats up, the heat travels through the air.
  • This is important to think about when building your oven. Solar energy is your main form of heat. How will you harness it?

Insulation:
Insulation is the opposite of conduction. You use insulation to keep heat from escaping, or to keep heat from conducting too quickly. Insulation is used in the walls of our houses to keep them warm during the winter. We also use oven mitts to insulate our hands from hot dishes that we remove from the oven.
  • Where do you want to keep the heat in your oven? Where do you want to make sure heat can flow easily?
Reflection:
Sunlight can be reflected, or "bounce back" from smooth, shiny surfaces. This can be a way of redirecting light. Light creates heat energy.
  • How can you use reflection to bounce light energy where you want it in your oven?

Designing and Building Your Oven:

1. Start with a blueprint! Draw what you hope to build, and label the materials you will use.

2. Build your oven.

3. Test it out! Place your oven in an area that will get steady sunlight. Keep in mind that houses and trees can cast large shadows when as the sun passes overhead.

4. If your oven didn't work the way you'd like, how can you change it to see if you can make it work better?

5. Test it again!

This is the process professional inventors and engineers use. You're well on your way to becoming an engineer!

Learn Science with LEGO®: The Unofficial Guide to Learning with LEGO® Book Review

http://www.ebooktag.com/learningwithlego-43HD35Zd7brD

I'm so excited to be sharing this great book with you today. The Unofficial Guide to Learning with LEGO®100 Inspiring Ideas launches July 5th, 2016. In addition to a ton of wonderful science, STEM (science, technology, engineering, math) and STEAM (add in some art!) ideas, which we will highlight in more detail below, this guide also provides activities to build the foundation for reading and math skills.

This post contains affiliate links, please see disclosures for more details.
http://www.ebooktag.com/learningwithlego-43HD35Zd7brD

The Unofficial Guide to Learning with LEGO® is laid out in a clear and readable way with vivid pictures of each project. Each activity page includes a list of the materials and supplies needed, succinct instructions for the activity, and notes the academic skills the project works towards.


You can get your copy of the ebook here

On top of elementary reading and math skills, there are a wide range of science related projects included. I think what is most valuable about these projects is that although they could work as a stand-alone activities, they use LEGO® as a way to augment and enrich a learning experience, rather than just provide a quick, disconnected building activity.

My favorite example of this is the Bug Hotel project. Building the structure for the bug hotel is just the beginning of a learning experience. It gives the task an engineering element, and then sets the child free to use what they have built in a science investigation. This is true STEM learning, not only using science concepts but also design and engineering to accomplish the project.

http://www.ebooktag.com/learningwithlego-43HD35Zd7brD

I also really liked the idea of using LEGO® bricks to build science diagrams. Some examples are: insect life cycles, cloud charts, bodies of water, and insect anatomy. The book includes printable labels that can be used in these diagrams. Students can learn about insects for an example through video, book or outdoor exploration and then build their diagram. The cloud chart could be taken outside to identify clouds on their next cloud walk. These activities would be valuable in any elementary science classroom, homeschool, camp or for informal learning at home.

Some other science activity highlights are experiments like water displacement, boat floating and sinking, and measuring weights. Some fun STEM challenges include: building balloon cars, a tennis ball challenge, and building a wind-powered car. Add in some art and make it a STEAM project, like the Duplo paint machine, pendulum painting or designing a seasons of the year mosaic.



You'll find such a wide variety of activities in this book! I was very impressed with the creativity and quality of each project. In addition to the ebook version, you can purchase the guide in paperback or for kindle from Amazon, by clicking these links or clicking on the book image above!

If you enjoy the book, you'll want to stop by the author's blogs for more great ideas just like these. You'll find them here:

Did you know that you can rent LEGO® and other toys, rather than purchase them? Check out the Pley program to find out more.
