Learn how to spot everyday problems and think of tools or objects that can fix them!
People have always had problems they wanted to fix. A problem is something that makes life hard or tricky. When people see a problem, they think of ways to solve it. They make new tools and objects to help! Let's look at some times in history when people did just that.
Every great invention started with someone saying, "I have a problem!" The first step to fixing anything is to notice the problem and explain it clearly. That is what we will learn to do today!
A simple problem is something that bothers you or makes a task hard. It is something you can describe in just a few words. Once you know the problem, you can think of a new or improved tool to fix it.
Let's look at a picture that shows how we go from a problem to a solution. Follow the arrows from left to right!
Look at the red box first. That is where you notice something is wrong. The yellow box is where you use your words to explain the problem. The green box shows a tool or object idea that could help. Every great inventor follows these steps!
Defining a problem means using your words carefully. You need to answer three questions. These questions help you think clearly so you can find the best solution.
When you answer all three questions, you have defined your problem. Now you are ready to think about what new or improved tool could help!
Simple problems come in many shapes and sizes. Let's look at different kinds of problems you might see every day. The picture below shows five types of problems and what kind of tool might help.
When you look at the chart, you can see that problems fit into groups. Something might break, be hard to do, get messy, take too long, or be missing. Knowing which kind of problem you have helps you think of the best fix.
Let's practice! Imagine you are eating cereal for breakfast and the milk keeps spilling when you pour it. Let's define this problem step by step.
Great job! Now someone could invent a smaller milk jug with a special slow-pour spout. That would be a new or improved tool that solves this problem.
Some ways of describing a problem are really helpful. Others are too fuzzy. Let's compare good problem definitions with tricky ones that need more work.
| Tricky (Too Fuzzy) | Good (Clear!) | Why It's Better |
|---|---|---|
| "It's bad." | "My backpack is too heavy to carry." | It tells us what and why. |
| "I don't like it." | "My water bottle leaks in my bag." | It says exactly what goes wrong. |
| "Fix this." | "We need a way to keep our art supplies from rolling off the table." | It tells who needs help and what the problem is. |
Defining a problem is just the first step in engineering design. After you define the problem, you get to do even more fun things! Let's peek at what comes next as you grow as a young engineer.
| What You Learn Now | What You Learn Later |
|---|---|
| Notice a problem in your day. | Research problems by asking many people. |
| Describe the problem with words. | Write a detailed problem statement. |
| Think of one tool idea. | Brainstorm many ideas and pick the best one. |
| Draw your idea. | Build a model and test it. |
Right now, the most important skill is learning to see problems clearly and talk about them. Once you can do that, you are on your way to becoming an awesome inventor!
Today we learned how to define a simple problem. A simple problem is something in everyday life that is hard, broken, messy, or slow. We learned to use the three magic questions — Who, What, and Why — to describe a problem clearly. A good problem statement tells exactly what is wrong so someone can think of the right new or improved tool to fix it.
Remember, every great invention starts with someone saying, "I have a problem!" By noticing problems around you and describing them clearly, you are already thinking like an engineer. Keep your eyes open — the next great idea might be yours!
