Step Two
Pick one idea from Step One's list. Brainstorm about fifteen ideas from that topic. Record class ideas on the blackboard.
example: jobs around the house
cutting grass | washing dishes | making beds |
raking leaves | washing the car | washing floors |
Step Three
Pick one idea from Step Two's list. Brainstorm about fifteen ideas from your chosen idea. Record class ideas on the blackboard.
example: cutting grass
lawn mower | gas mower | cutting height |
electric mower | pollution | dumping clippings |
raking clippings | wet clippings | dry clippings |
grass clippings | mowing in patterns | push mower |
Step Four
Pick one item from Step Three's list. Brainstorm about fifteen problems found from that topic. Record problem on the blackboard.
example: electric mower
handling the cord can be a problem | cord not long enough |
Step Five
Discuss the problems found in Step Four and have students device ways to solve the problems. Allow students to discuss their devices and how they would work. These are the students' inventions.
example: handling the cord can be a problem
have mower stay in range of an electric eye which can be moved to different locations |
The invention is a lawn mower with a movable electric eye.
Step Six
Let the class choose another topic from Step One's list. Divide the class into groups of four or five students. Each individual group follows Steps Two, Three, Four, and Five. Each group must draw a picture of their invention from Step Five and present it to the class. This is a great springboard for class discussion. It will also help you evaluate whether the students are ready to begin working individually in their Invention Diaries.
Step One
Students are now ready to use their Invention Diaries. On the first sheet of notebook paper, each student should copy the class brainstormed list from Step One of Part Two into his/her Invention Diary. As they are copying the items, encourage students to add to the list. This will be the students' pool bank for inventing.
Step Two
Have the students circle five topics from the list that interest them. The students write these topics, one per page at the top of five sheets in their booklet beginning with page 2 and continuing to pages 4, 6, 8, and 10.
Step Three
The students then follow Steps One, Two, Three, Four, and Five from Section Two for each topic. This entire process can take up to two weeks or longer depending on how much time you allow each day.
Step Four
Students pick one of their inventions to explain to another classmate. The students share how they arrived at their invention. The listener evaluates the invention and offers ways to improve it. This new information is recorded in the booklets.
Step Five
At this time the students should begin to narrow their list of possible inventions for an Invention Fair. Check with each student to evaluate his/her progress. Students should select one invention and begin creating it at home.
With students making inventions, an invention fair is a wonderful way to culminate an invention unit. Discuss with students the criteria used for the invention fair.
innovative | creative, original, feasible |
overall presentation | how the project looks, display quality |
clear information | reader can understand information placed on "Invention Form" |
Give each student a copy of "Invention Form". Discuss with the students the importance to write why the invention is needed and how it works.
