SECTION 1
Why Do We Look Closely at Problems?
People have always had problems to solve. A long time ago, people needed to stay dry in the rain.
They looked closely at the rain. They watched where it fell. Then they built shelters!
Looking closely is called making observations. That means using your eyes, ears, nose, and hands to learn about something.
Long Ago โข Staying Dry
Later โข Carrying Water
Even Later โข Crossing Rivers
Today โข You Are an Observer!
Every time people solved a problem, they started by looking closely. That is what we will learn to do!
SECTION 2
What Are Observations?
When you make observations, you use your senses. That means you use your eyes, ears, nose, hands, or even your tongue!
An engineer is a person who designs things to solve problems. That means they make things to help people.

SECTION 3
See How We Observe a Problem
Let us look at our anchoring phenomenon! Imagine you are on the playground. The slide is too hot to go down. Ouch! What can we observe about this problem?
We used our eyes and hands. We asked questions. Now we know a lot about the problem! The sun heats the metal slide.
SECTION 4
How Engineers Observe Problems
Engineers follow steps when they observe a problem. They look, listen, touch, and ask questions. Then they think about what they noticed.
This is part of the engineering design process. That means the steps people follow to solve a problem.
Stay Safe!
SECTION 5
Using All Your Senses
Different problems need different senses. Let us see which senses help with which problems!
| Sense | What You Do | Example Problem |
|---|---|---|
| ๐ Sight | Look at it closely | A torn book page |
| ๐ Hearing | Listen carefully | A squeaky door |
| ๐ค Touch | Feel it gently | A bumpy road |
| ๐ Smell | Sniff the air | Stinky trash can |
Different senses help us observe different problems.
A crosscutting concept we use is structure and function. That means the shape of something tells us how it works. When we observe, we look at the shape and parts of things.
For example, if a cup has a crack, the shape changed. Water leaks out! The structure tells us about the problem.
SECTION 6
Let Us Try It Together!
Here is a problem: The class pet hamster's water bottle is empty every morning! Let us make observations.
Observing the Hamster's Water Problem
- 1
Step 1 โ Look at it
We look at the water bottle. We see it is empty. We look at the cage. The bottom is wet!We see: empty bottle, wet cage. - 2
Step 2 โ Listen to it
We fill the bottle and listen. We hear drip, drip, drip! Water is dripping from the bottom.We hear: water dripping. - 3
Step 3 โ Touch it safely
We carefully feel the bottom of the bottle. There is a tiny crack! Our finger feels it.We feel: a crack on the bottle. - 4
Step 4 โ Ask questions
We ask: Why is the water leaking? The crack lets water drip out! Now we know the problem.The problem is a crack in the bottle!
Great job! We used our senses to find the problem. Now we can think of a way to fix it!
SECTION 7
Good Observations vs. Guesses
Sometimes we guess what the problem is. But good observations are better than guesses. Let us compare!
| Guessing | Observing |
|---|---|
| "I think the toy broke because it is old." | "I see a missing wheel on the toy car." |
| "Maybe the plant is sad." | "The plant's soil feels dry. The leaves look brown." |
| "The door is probably stuck." | "I see a rock blocking the door at the bottom." |
Observations use our senses. Guesses do not.

SECTION 8
After We Observe, What Comes Next?
Making observations is just the first step! After we observe, we can start thinking of solutions.
| What We Do Now | What Comes Next |
|---|---|
| Look at the problem | Draw or tell about the problem |
| Use our senses | Think of ideas to fix it |
| Ask questions | Build something to help |
| Find the real problem | Test if our idea works |
Observations lead to solutions!
You are learning to think like an engineer! First observe, then design. You will learn more about designing solutions next time.
SECTION 9
Practice Time!
A bird feeder in the school garden is broken. Birds cannot get the seeds. Let us practice making observations!

SUMMARY
What We Learned
Summary
Today you learned that making observations means using your senses to learn about a problem. You look, listen, touch, and ask questions. Observations help you find the real problem.
You are thinking like an engineer! Engineers observe before they fix. Observations are better than guesses because they use real clues. The structure of something tells us how it works. Keep observing the world around you!
