SECTION 1

Why Do People Make New Things?

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.

Long Ago

Stone Tools

People needed to cut food and build shelters. They used sharp rocks as the first tools!

1800s

The Umbrella Gets Better

People got wet in the rain. Someone made a folding umbrella that was easy to carry everywhere!

1900s

Band-Aids Are Invented

A man noticed his wife kept getting small cuts in the kitchen. He made a sticky bandage she could put on all by herself!

Today

New Ideas Every Day

Kids and grown-ups still find problems and think of new tools to solve them. You can too!

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!

SECTION 2

What Is a Simple Problem?

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.

Notice the Problem

Look around you. What is hard to do? What makes you say "I wish I could fix that"?

Describe the Problem

Use words to explain what is wrong. Tell who has the problem and what makes it tricky.

Think About a Solution

Ask yourself: Could a new tool or object help? Could we make something we already have even better?

Share Your Idea

Tell a friend or draw a picture. Sharing helps you make your idea even better!

✦ KEY TAKEAWAY

Defining a problem is like being a detective. A detective looks for clues before solving a mystery. You look for problems before inventing a solution! First, you find the problem. Then, you describe it. Only then can you think of the best tool to fix it.

SECTION 3

Seeing Problems and Solutions

Let's look at a picture that shows how we go from a problem to a solution. Follow the arrows from left to right!

This diagram shows three steps: first you notice a problem, then you describe it clearly, and finally you think of a solution idea.

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!

SECTION 4

How Do We Define a Problem?

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.

The Three Magic Questions

Who has the problem? (A person, an animal, or a group)
What is the problem? (What is hard or not working?)
Why does it need to be fixed? (Why does it matter?)

💡 Try It!

Think about your lunchbox. Is it ever hard to open? Is it too heavy? Does your food get squished? If so, you just found a simple problem! Now try to say it: "My lunchbox squishes my sandwich because it does not have a strong lid."

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!

SECTION 5

Different Kinds of Simple Problems

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.

This chart shows five types of simple problems. Each one has a matching tool idea. Notice how the problem always comes first, and the solution comes after.

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.

SECTION 6

Let's Define a Problem Together!

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.

The Spilling Milk Problem

Step 1 — Notice the ProblemYou are eating breakfast. Every time you pour milk from the big jug, it splashes and spills on the table. This is a problem!

Problem noticed: Milk spills when I pour it.

Step 2 — Ask WHO Has the ProblemWho has this problem? You do! And maybe your little brother or sister does too. Anyone who pours milk from a big jug might have this problem.

Who: Kids who pour milk from a big, heavy jug.

Step 3 — Ask WHAT Is the ProblemWhat exactly goes wrong? The milk jug is too big and heavy for small hands. When you tip it, the milk comes out too fast and splashes.

What: The jug is too heavy and the milk pours too fast.

Step 4 — Ask WHY It Needs to Be FixedWhy does this matter? Spilled milk makes a mess. Someone has to clean it up. It also wastes milk!

Why: It makes a mess and wastes milk.

Step 5 — Define the Problem in One SentenceNow put it all together in one clear sentence. This is your problem statement.

"Kids need a way to pour milk without spilling because the jug is too heavy and the milk comes out too fast."

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.

SECTION 7

What Makes a Good Problem Definition?

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.

Comparing fuzzy and clear problem definitions

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.

✦ KEY TAKEAWAY

Think of defining a problem like giving directions. If you say "go somewhere," nobody knows where to go. But if you say "walk to the big red door," everyone can find it! A good problem definition tells people exactly what is wrong so they can find the right fix.

SECTION 8

From Defining to Designing

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.

How problem-solving grows as you learn more

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!

SECTION 9

Practice Problems

PROBLEM 1 — CONCEPTUAL

What is a "simple problem"? Tell what it means in your own words.

PROBLEM 2 — BASIC

A girl notices that her sandwich gets squished in her lunchbox every day. Use the three magic questions (Who, What, Why) to define her problem.

PROBLEM 3 — INTERMEDIATE

Read these two sentences. Which one is a better problem definition, and why? Sentence A: "I don't like recess." Sentence B: "When it rains, the playground gets muddy and we slip when we run."

PROBLEM 4 — APPLIED

Look around your classroom or home. Find one simple problem. Write a problem statement using this pattern: "[Who] needs a way to [do what] because [why]." Then draw or describe a tool that could help.

PROBLEM 5 — CRITICAL THINKING

A boy says: "I need a robot that does everything for me." Is this a good problem definition? Why or why not? How could you help him make it better?

SUMMARY

What Did We Learn?

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!
