Mini Lesson

Inventors look at a problem in the world and think: "What could I make to fix this?" You can be an inventor too — and technology can help you design your idea!

What is an invention?

  • An invention is something new that someone creates to solve a problem or make life better.
  • Example: The umbrella was invented to solve the problem of getting wet in the rain.
  • Every invention starts as an idea — drawn on paper or a screen.

How do inventors plan their ideas?

  1. Identify the problem: What problem do you want to solve?
  2. Draw your invention: Sketch what it looks like.
  3. Label the parts: Name each part and what it does.
  4. Explain it: Write one sentence about how it helps people.

Technology as a design tool

  • You can use a drawing app to sketch your invention digitally and add labels with a text tool.
  • A digital design is easy to change and share — just like a real engineer would do!
