Liquid Lab Slides Liquid Lab
Lesson 1: Full and Empty
The Spill Challenge
"Can you fill this cup to the very top without spilling a single drop?"
How do we know when to stop pouring?
Empty
There is nothing inside the container.
Full
The container is all the way to the top!
Half-Full
It is right in the middle.
Overflow
Too much! The liquid is spilling out.
To the Lab!

Water Wizards Teacher Guide Water Wizards
Teacher Facilitation Guide • Lesson 1
Kindergarten Science
Learning Objective
Students will explore the concept of capacity by filling containers to various levels and using descriptive vocabulary: full, empty, half-full, nearly full, and overflowing.
Materials
Clear plastic cups
Water table or large bins
Blue food coloring (optional)
Sponges/towels (for overflow!)
The Hook (5 mins)
Display a clear cup and a pitcher of water. Use the "Spill Challenge" slide.
"I have a challenge! I want to fill this cup as much as I possibly can without spilling a single drop. When should I stop? Tell me to 'stop' when you think it's ready."
Direct Instruction & Vocab (10 mins)
Use the Liquid Lab Slides to introduce vocabulary. Perform live demos alongside the slides:
1
Empty:
Turn the cup upside down to show nothing is in it. "Is it empty? Is there anything inside?"
2
Full:
Fill to the brim. "It's full! It's at the top. Can I add more?"
3
Overflow:
Deliberately overfill. Let students see the water spill over. "Oh no! This is called an overflow. Why did it happen?"
The Liquid Laboratory (20 mins)
Move students to the water stations. Give them specific commands to practice precision and control:
"Fill your cup half-full!"
"Make your cup nearly full!"
"Now make it empty!"
"Can you make it overflow?"
Teacher Tips & Misconceptions
• Surface Tension: Students may notice the "bump" of water at the top of a full cup. This is a great observation for "Nearly Full" vs "Full".
• Half-Full: Students often struggle with the middle. Encourage them to find the "center" of the cup's height.
• Air is Something: For advanced learners, you can mention that an "empty" cup is actually full of air!

Lesson 2: Comparing Capacity
Which one holds more juice?
A
Tall & Skinny
OR
B
Short & Wide
"Looks can be tricky in the Liquid Lab!"
Prediction
A prediction is a smart guess about what will happen.
"I predict that Container B will hold more water because it is wider."
The Pour Test
1
FILL
Fill Container A all the way to the top.
2
POUR
Carefully pour it into Container B.

LOOK
Does it overflow? Or is there space left?
Compare It!
MORE
This container holds a larger amount of liquid.
LESS
This container holds a smaller amount of liquid.
SAME
They both hold the exact same amount!
Scientist Challenge
Pick two containers. Predict which one holds more.
Prediction Power Teacher Guide Prediction Power
Teacher Facilitation Guide • Lesson 2
Kindergarten Science
Learning Objective
Students will practice making predictions and use the Pour Test method to compare the capacity of two different containers.
Lab Setup
5 Pairs of containers per table
Use varied shapes (tall/thin vs short/wide)
Funnels (optional but helpful)
The Pour Test Method
This is the most direct way to compare capacity without measuring units yet.
Condition A: Overflow
If you pour Cup 1 into Cup 2 and it spills, Cup 1 holds more .
Condition B: Extra Space
If you pour Cup 1 into Cup 2 and there is room left, Cup 2 holds more .
The Hook (5 mins)
Show two containers that look very different but hold similar amounts (e.g., a tall thin bottle and a squat bowl).
"Scientists, look at these two. Which one do you think is 'the winner'? Which one holds more? Why do you think so?"
Teaching Prediction (10 mins)
Introduce the word Prediction . Emphasize that it's okay if a prediction is "wrong"—that's how we learn!
Prompting Questions:
"Is it bigger because it is taller?"
"Is it bigger because it is fatter (wider)?"
"What did our eyes tell us? What did the water tell us?"
Investigation (25 mins)
Students work in pairs. Each pair chooses a set of containers from the "Lab Tray".
Steps for Students:
1 Circle your prediction on the worksheet.
2 Fill Container A.
3 Pour into Container B.
4 Talk about the results!
Facilitation Tips
• Scaffolding: Use a marker to label containers "A" and "B" to match the worksheet.
• Vocabulary: Encourage students to use "more", "less", and "same" during their discussions.
• Spills: Spills are part of the science! Keep towels nearby and encourage students to "reset" their station.

Measure • Count • Record
Counting Capacity Teacher Guide Counting Capacity
Teacher Facilitation Guide • Lesson 3
Kindergarten Science
Learning Objective
Students will use a non-standard unit (scoops) to measure the capacity of various containers and record their findings numerically.
Math Skills
One-to-one correspondence
Writing numbers 1-20
Comparing quantities
The Rules of the Scoop
Measuring volume requires precision. If the scoops are different sizes, the measurement is not accurate.
Leveling
Teach students to use a finger or a flat stick to level off the scoop so it isn't "heaped".
Iteration
Each scoop must be emptied completely into the container before the next one is started.
The Hook (5 mins)
Bring out a large pot and a very small scoop (like a coffee scoop or a laundry detergent scoop).
"We need to fill this 'Soup Pot' for lunch! But we only have this tiny blue scoop. How many times will I have to scoop to fill it up? 5? 10? 100?"
Modeling the Count (10 mins)
Perform a live demo. Have the class count aloud together as you scoop.
Common Pitfall:
Students often lose count if they get distracted by the water. Encourage "Point Counting" - tapping the worksheet after each scoop.
The Scoop Lab (25 mins)
Set up stations with different containers. Students move from one to the next, recording their counts.
Station 1
Coffee Mug
Station 2
Cereal Bowl
Station 3
Mixing Bowl
Discussion Prompts
• "Which container took the most scoops? Why?"
• "Which container was the smallest? How many scoops did it hold?"
• "If we used a bigger scoop, would we need more or fewer scoops to fill the cup?" (Advanced Challenge)

The Reveal
Same Amount!
Liquid changes shape to fit its container, but the amount stays the same.

The Test
Pour the water back and forth. Watch it change!
The Truth
It looks like more, but it's really the same.
Conservation Master Teacher Guide Conservation Master
Teacher Facilitation Guide • Lesson 4
Kindergarten Science
Learning Objective
Students will observe that the amount of liquid remains the same even when its shape changes by being poured into a different container.
Key Skill
Observation
"My eyes say it's more, but my brain knows it's the same."
The Science Secret
Most Kindergarteners are in the "pre-operational" stage. They often think a tall container holds more simply because the water level is higher. This lesson challenges that "visual bias."
How to Explain it:
"We didn't add any new water. We didn't drink any water. So it has to be the same amount, even if it looks different!"
The "Magic" Trick (10 mins)
Set up two identical clear cups. Fill them to the exact same level with blue water.
Ask: "Do these have the same amount? How can you tell?"
Pour Cup A into a tall, very skinny cylinder.
Ask: "Now which has more? Or are they still the same?"
Proving the "Magic" (10 mins)
Pour the water from the skinny cylinder back into Cup A. This is the "Aha!" moment.
"Look! It went right back to where it was. It never changed amount. It just changed clothes (containers)!"
Exploration Stations (20 mins)
Students test this themselves. They need identical pairs of containers and one outlier container.
Station Mission:
1. Fill two cups the same.
Discussion Questions
• "Why did the water look like 'more' in the skinny cup?"
• "If I poured this water into a swimming pool, would it still be the same amount?"
• "Can water ever disappear when we pour it?" (Intro to evaporation/absorption)
Same Amount Worksheet Same or Different?

Teacher Facilitation Guide • Lesson 5
Kindergarten Science
Learning Objective
Students will apply their knowledge of capacity to estimate and select a container that matches a specific volume target (e.g., 5 or 10 scoops).
Team Skills
• Encouraging others
• Taking turns
• Sharing ideas
What is Estimation?
Estimation is not just a random guess. It's using evidence from past lessons.
Guided Talk:
"Scientists, remember when the cereal bowl held 12 scoops? Today our target is 5. Should we pick a container that is bigger or smaller than the cereal bowl?"
The Mission (5 mins)
Introduce the "Target Number". For most K students, 5 or 10 are the best targets to start with.
"Your team must find a container that holds exactly 10 scoops!"
Team Roles (10 mins)
Assign (or let students pick) roles to ensure everyone is engaged:
The Scooper
Pours the water.
The Counter
Says the numbers.
The Checker
Marks the paper.
The Capacity Hunt (25 mins)
Lay out a wide variety of containers (many from previous lessons). Teams go on a "hunt".
Trial and Error:
"Encourage teams to try multiple containers if their first one isn't the target. Ask: 'Was that too much or too little? What should we try next?'"
Pacing & Management
• Water Management: Use plastic trays to catch spills. This is the messiest lesson!
• Small Groups: 3-4 students per group is ideal for role distribution.
• Celebrating Success: Even if a team gets 11 instead of 10, celebrate how close they were!
