2. Gather information
About Need/
Problem
What plants can live for a long time without water?
How much water do they need?
What do they need in the water? Fertilizer?
What could I make to feed them with water slowly?
I know that Plants need light and water.
3. DEVELOP A PLAN.
Criteria
• Design a water feeder for pot plants
• It has to last for at least a week
• It has to let the water out slowly
• It has to be safe so it doesn’t flood or make
a mess
• It has to be put in the light and not let the
water evaporate.
• It can’t let the water out to quickly.
5. P M I
*The water comes out
slowly
*It is cheap to make
*It is easy to make *The tighter the screw
*The tin went rusty was in the less water
*It is easy to fill This could poison the came out
plant.
*It works *It was hard to count
and time the drips
*It lets just a very small because it slowly leaked
amount of water out so it out
will last a long time
*After 3 days the drops
* It has a lid and that will could be counted I
stop water evaporating if every 10 seconds
the weather is hot
* It won’t tip over and
make a mess
* It looks good
6. ✴ IMPROVEMENTS I made
✴ I screwed the screw in more so it lasted
longer.
✴ Changed the height to make it flow better
