KID'S FUN WATER EXPERIMENTS

KID'S FUN WATER EXPERIMENTS

"DRINKING WATER IS RARE AND PRECIOUS." Everyone needs to" practice Water Conservation.

Turn on the tap.
Fresh, clean, drinkable water pours out! That water may come from a nearby lake. The lake gets water from runoff water when it rains.  The water runs over land that is dirty. The water in the lake is dirty. It has a medium brown color.

How is dirty water cleaned? Let's have some "science water fun!" "Water experiments are cool and wet!" How about a great "outdoor water Science Fair Project?" Let's use natural stuff as water filters to "make dirty water clean water." Let's make" natural homemade 'Water Filter Systems" and experiment with them. 

Violent weather events, earthquakes, and floods are becoming increasingly common. Often this means there is no drinkable water for days. "Survival Training for Kids" has become important. Knowing how to make dirty water clean and safe to drink anywhere you are is a valuable skill well worth developing.

WATER FILTER SYSTEMS MATERIALS LIST:
1. Each group of kids needs three (2 liter) pop bottles cut in half horizonally.
2. Cotton pads
3. Sand, pea gravel and larger gravel pieces of rocks
4. Medium brown dirty water
5. A measuring cup
6. Notepad, pencil and a camera (if one is available). If not, drawings will be fine.

PROBLEM: Which "natural filter system" changes dirty water to clear water best?  (Best means: how many times did you have to run the water back through the filter before it was clear?) The fewer repeats, the better the filter.

HYPOTHESIS: The filter system containing _________________________________________, cleared up the water best. "(Take a guess, then test.)"

                               

PROCEDURE: 


Hint: "When turned over, the top half of the pop bottle looks like a funnel. The natural stuff goes in this part in this order:"

1. Put 4 cotton balls in the spout so the filter stuff cannot fall through to the other half of the bottle which catches the filtered water.

2. Add the natural stuff on top of the cotton balls. Set up 3 pop bottle systems as follows:
    a. cotton balls + sand     b. cotton balls + pea gravel  c. cotton balls + larger gravel

3. Pour 2 cups (500) ml. of dirty water on top of the filter stuff for each filter system.  OBSERVE AND RECORD WITH WORDS AND DRAWINGS.

4. Keep pouring the filtered water back through each system until it is clear. ( RECORD HOW MANY TIMES IT TOOK, for the water to become clear, if it did.)

5. Which of these systems worked best? (DRAW PICTURES OR TAKE PHOTOS.)

GOING FARTHER IN BUILDING "CREATIVE PROBLEM SOLVING SKILLS."

CLEAN UP THESE SYSTEMS, THEN MAKE UP YOUR OWN FILTER MIX AND SEE HOW IT WORKS. CONTINUE THIS UNTIL YOU HAVE THE FASTEST, BEST FILTER MIX.  THIS EXPERIMENT GETS THE "Great Kid Scientist 'SUPER FILTER' AWARD!"

RESULTS: My hypothesis was (true) - (false). (Write down the one that fits your first experiment.)  Then tell what you learned from all your experimenting.

"SHARING IS CARING" Use your drawings, photos and words to prepare a great report to share with others. ASK YOUR PARENTS TO TAKE YOU TO A "WATER TREATMENT PLANT" NEAR YOU, OR GOOGLE "Water Treatment Plant." FIND OUT EVERYTHING THEY DO TO WATER TO MAKE IT SAFE TO DRINK. INCLUDE THIS AS RESEARCH IF YOU USE THESE EXPERIMENTS AS A SCIENCE FAIR PROJECT. Be sure to repeat the experiments 3 times for a science project.
