3rd Grade -Inventors and Inventing

Third Grade Enrichment students will be learning about famous inventors and the process of inventing. We will do lots of activities that help us learn how to use our creative thinking and problem solving skills. The final project will be an original invention made by each student.

Here is the assignment that will be given in class:


Your Individual Invention


Your assignment is to develop your own invention. This invention can be anything you are interested in. As you begin to think about your invention, remember that the simpler the invention, the better. If your invention is highly complicated, it will be difficult to complete this assignment on time.


Your invention is due during enrichment class on December 14 or 8, 2009.

Ideas? To come up with invention ideas, think of things such as the following:
· Chores you have to do that could be made easier or an invention that might help someone you know
· Problems that all kinds of persons face each day that a new invention would help them overcome
· Things that people would enjoy doing more than they do now if you could….
· And ?????
Making a Model You will need to make a model of your invention. This does not need to be a working model, and it should not cost much money to make. Try to use things you have around the house to make your model. You should jot down how much the materials cost to make your invention. If you use items around the house to make the model, estimate what their value would be.
Survey The information about cost will also help when you survey people asking whether they would be interested in your invention. Most people will want to know how much your product will cost before telling you if they would be interested in buying it.
Sharing your model At the end of this unit, you will be sharing your model with the class. You will need to be able to answer questions posed by your classmates and your teacher.


Keeping a Log

v Description – a written description of your invention idea should be the first page of your log.
v Research – conduct research to find out if your idea is original. You may have to visit local business or make a phone call or two to see if the invention exists. Remember to thank people for helping you collect your information.
v Diagram – draw a labeled diagram of your invention on one page of your log book.
v Materials – make a list of the materials you will need to make a model of the invention.
v Model – as you are building the model of your invention, write about your experiences on a page in your log book. Even though your model does not need to work, you may still make adjustments and changes in your original plan for your model. Keep track of how much the materials cost to help you on the marketing page.
v Marketing – You should survey people in the age group that you feel would be interested in purchasing your invention if it were for sale. Ask a number of people if they would be interested in buying the invention when it becomes available to the public. Give them an idea about how much your product would cost.. Make the calculation by adding up the cost of materials plus an amount to pay you for the time it took to build the model. Show the results of your survey in your log book.

We will make a log book in class for you to record this information.
