The first thing to remember is that your visual presentation whether an Demonstration or Illustrated talk comes from the project you are enrolled in during this 4-H program year. And you certainly don't have to decide between whether your visual presentation is a demo or talk. That is just something for your benefit to help you organize your thoughts.
So first look at your project area. Let me think of something general enough that everyone can relate. For an example lets say a member is registered and working through a project on Safety this year.
Take a big piece of paper and make a column on the left. Write 4-H Project as a header and then below it write safety. Move over one space and write General Topic area. Under this write all the things that come to mind that you may have been studying about safety. For example in this brain storming list you might have: Fire, Camping, Children, Lawn Mower, Automobile, Poisons, Animals, Helmet, ATV, Bike. The list can go on an on.
PROJECT GENERAL TOPIC
The first rule is PICK SOMETHING THAT INTERESTS YOU!!!!
So in our example maybe our person is thinking about driving someday and picks Automobile Safety
Move over a column and title it "Specific Areas". Now brainstorm a list of all the possible Automobile Safety Topics that come to mind. Remember in Brainstorming you write anything that comes to mind down on the paper. You might have things like: Insurance, Alcohol & Drugs, Seat Belts, Changing Tires, Safety Features, Air Bags, Safe Driving Skills and on and one again.
PROJECT GENERAL TOPIC SPECIFIC AREAS
Safety Fire Insurance
Camping Alcohol & Drugs
Children Seat Belts
Lawn Mower Changing Tires
Well our person in this example picked SEAT BELTS
So the last column title "Breakdown of One Area" Now you might think about Seat Belts and come up with: Demonstrate with Dummies; Types of injuries they prevent; seat belt laws; kinds of seat belts; how they operate.
PROJECT GENERAL TOPIC SPECIFIC AREAS BREAKDOWN ONE AREA
Safety Fire Insurance Demonstrate with Dummies
Camping Alcohol & Drugs Types of injuries prevented
Children Seat Belts Seat belt laws
Lawn Mower Changing Tires Kinds of seat belts
Now you have some clear specific things to work into your presentation. See how that works?
