Spring into STEAM - Dive In!
Spring into STEAM is the San Diego Public Library’s science-focused program series for 9 - 12-year-old students. Workshops take place during the months of March, April and May at all 36 branch libraries across the city.
We are partnering with local science experts and organizations to create a truly unique educational experience. Unable to make it to a program this Spring? Don’t fret! Complete the Dive into DIY! Project at home and stop by your local library to get a prize.
Dive into DIY: Make a Splash at Home!
DIY Self-Watering Plant
- One 2 or 3 liter soda bottle with the cap
- A piece of newspaper, a piece of plastic from a bag or a piece of aluminum foil
- Cotton string
- scissors to cut the bottle
- a drill (or something similar) like a hammer & nail for making a hole in the cap
- tape (optional)
- A small plant or some seeds
- Cut plastic bottle in 1/2 , two-thirds of the way down.
- Poke or hammer a hole into the cap (take off of bottle first and be careful!
- Put a 6” piece of string through the hole in the cap and tie off on the inside of the cap.
- Put cap back on the bottle top.
- Put some water in the cut off bottle bottom.
- Turn the top of the bottle with the cap and string on it upside down and place in the bottom of the bottle so that the string hangs down in the water.
- Once it is in, pull the string about half of the way through to the top so that it is evenly between bo9th parts of the bottle.
- Put dirt in the top section and allow the string be mixed in with the dirt.
- Either plant some seeds in the dirt or plant a plant and your new self-watering plant!
DIY Water-Filtration System
- Water bottle
- Scissors or small screwdriver with a pointed end
- Coffee filter or cotton balls
- Sand or charcoal
- Large gravel or small rocks
- 1 empty plastic cup
- 1 cup to hold dirty, muddy water
- Using your scissors, cut off the very end of the water bottle (approx. ¼ inch).
- Remove cap from water bottle. Using your scissors, or a small screwdriver, make a small hole in the center of the cap.Please be careful!
- Replace cap with the hole in it. Now place your coffee filter (or one small cotton ball) through the bottle and down by the cap. You may have to cut the size of the coffee filter down to make it fit in the small part of the bottle. If you are using a standard 16.9 oz water bottle, the piece of coffee filter should be about 3 inches in diameter. You might need to use a pen to push the coffee filter/cotton down to the bottom.
- Now get your sand or crushed charcoal and fill up the bottle about 2 inches. It will be on top of the coffee filter.
- Next, add your gravel into the bottle. Around 2 inches of gravel should be enough.
- Finally add your larger gravel or small rocks into the bottle. Again, 1-2 inches is enough.
- Your water filter is now complete! Just put your “new” water filter over a clear, empty plastic cup (with the cap side down!)
- With the other cup, pour the dirty/muddy water into the filter.
- Watch your dirty water come out filtered.
- Boil the filtered water to completely rid of all bacteria and such!
