Our young third grade inventors dazzled us with their imaginations and applied knowledge of simple machines at our “Invention Convention” this past Thursday. This event is the culminating project in the Simple Machines unit for the Room 29 and 21 science classes. Each student invented a compound machine which performs a task and is built using at least three simple machines. The inventions have catchy names that reflect the task such as “Water Wheel Wonder”, “Balloon Poppin’ Machine” and the “Dog Treat Retriever 5000”. The children also completed a report about how their machine worked which included a discussion of changes the student had to make when things did not work out as originally planned. Some of the best inventions such as the Popsicle and Post-It notes are the result of a “mistake” . With this in mind, the children also discussed changes they had to make as they built their creations such as making a lever shorter to avoid launching a stuffed animal past its target. These projects are a wonderful display of the power of imaginations and simple machines. Congratulations boys and girls on a job well done!Check out the slide show "gadget" to the right for a slide show of all of our students with their creations.

I hope this is the right place to post this comment. I just wanted to congratulate all the kids on such creative and impressive inventions. The Invention Convention was genuinely interesting for me and was the highlight of my day.
Thanks,
