Opening Hook
Watch Carefully!
Your teacher is going to ask a student a question.
Watch everything that happens.
What did you see your teacher do?
- What question did they ask?
- What happened after the student answered?
- What did they write down?

Lesson
What Is a Survey?
A survey is when you ask a group of people the same question and record all their answers.
Ask → Listen → Record → Repeat
- 📌 Same question every time — word for word
- 👂 Listen carefully to the answer
- ✏️ Write it down immediately
- 🔁 Move to the next person

Lesson
How to Ask the Question
Here is the script we use today:
"Hi! I'm doing a survey.
What is your favorite season —
Summer, Fall, Winter, or Spring?"
- 😊 Use a friendly voice
- 👆 Point to the answer choices on the board
- ⏳ Wait for an answer — don't rush
- 🙏 Say "Thank you!" after

Lesson
How to Record Answers
After someone answers, put a check mark next to their choice on your recording sheet.
✅ Do This
Write it down right away before talking to anyone else.
One check = one person's answer.
❌ Not This
Try to remember it in your head.
Write it all down at the end — you might forget or mix up answers!
Your recording sheet is your scientific notebook. It holds the data so your brain doesn't have to!

Class Practice
Let's Practice Together!
Your teacher will ask the whole class the survey question.
- 🙋 Raise your hand for your favorite season
- 👀 Watch the teacher record on the board
- ✏️ You record on your sheet at the same time
- 🔢 Count up — how many for each season?
This is practice so when you go survey on your own, you already know exactly what to do!

Survey Tips
If You Get Stuck…
- 😟 Someone says "I don't know" → That's okay! Say "no problem" and move on
- 🙅 Someone doesn't want to answer → Say "that's fine!" and ask someone else
- 🤔 Someone gives an answer not on the list → Point to the board: "Which of these is closest?"
- 😰 You feel nervous asking → Take a breath, look at your script card, you've got this!
Real scientists face all of these. How you handle them is part of being a great data collector!

Brain Break — Count Our Data!
Everyone stand up!
Your teacher calls out each season.

Debrief
What Did You Find?
Count up your check marks for each season. Which got the most? Which got the least?
- ☀️ How many people said Summer?
- 🍂 How many said Fall?
- ❄️ How many said Winter?
- 🌸 How many said Spring?
Your 5 check marks are called responses. Each check mark = one person's answer. You just collected real data!

Big Idea
Why We Record Right Away
😬 If you wait…
- You might mix up who said what
- You might forget one person
- Your data will have mistakes
- You can't trust your results
✅ If you write right away…
- Every answer is saved
- No one gets forgotten
- Your data is accurate
- You can trust your results!
