Instructions
Let's remember the fun water filtration experiment! Follow the instructions for each activity to show what you learned about making water clean.
Activity 1: From Dirty to Clean!
Water filtration cleans dirty water. In the first box, draw the dirty water from the beginning of the experiment. In the second box, draw the cleaner water after it went through the filter.
Before Filtration (Dirty Water) |
After Filtration (Clean Water) |
Activity 2: Super Filter Materials
A filter uses different layers to trap dirt. Unscramble the letters to name the materials we used. Use the word bank to help you!
-
These are small rocks that stop leaves and twigs.

Activity 3: Why is Clean Water Important?
Read each sentence. If it's true, circle the happy face. If it's false, circle the sad face.
| 1. Drinking clean water helps you stay healthy. | 😊 😞 |
| 2. It is okay to drink muddy water from a puddle. | 😊 😞 |
| 3. Animals and fish need clean water to live. | 😊 😞 |
| 4. Filters make the water dirtier. | 😊 😞 |
Activity 4: Your Observations
Think like a scientist! What did you notice during the experiment? Fill in the blank or circle the correct answer.
1. The purpose of the filter is to __________________ the water.
(Hint: The answer starts with the letter 'c').
2. What happened to the dirt and leaves when you poured the water through the filter?
( ) They passed through with the water.
( ) They got trapped in the filter layers.
3. The water that came out of the filter was:
( ) Clearer than before.
( ) Dirtier than before.
Answer Key
Activity 1: From Dirty to Clean!
The "Before" box should show cloudy, brown, or murky water, possibly with bits of leaves or dirt drawn in it. The "After" box should show water that is much clearer and lighter in color.
Activity 2: Super Filter Materials
- GRAVEL
- SAND
- CHARCOAL
Activity 3: Why is Clean Water Important?
- Happy Face 😊 should be circled.
- Sad Face 😞 should be circled.
- Happy Face 😊 should be circled.
- Sad Face 😞 should be circled.
Activity 4: Your Observations
- clean
- They got trapped in the filter layers.
- Clearer than before.
