WHEN THE HOT SUMMER DAYS, HAVE YOU CHILLEN IN DOORS HOW ABOUT SOME SCIENTIFIC FUN TO KEEP KIDS LEARNING DURING THE SUMMER BREAK.
THESE FUN EDUCATIONAL IDEAS CAME TO US FROM MAD SCIENCE.
www.madscience.org/sacramento
YOU CAN WATCH THE FULL SEGMENT ON fox40.com
Mad Science Ooblech
1 box corn starch
1 bowl
1 wooden spoon
water
Fill the bowl 1/3 with water
Add the same volume of corn starch
Stir until mixed
If watery, add corn starch
If too stiff and dry, add water
Repeat until fully mixed with smooth surface.
Play with Ooblech (punch it, drop piano on it, poke it slowly with your finger)
Be amazed at this non-Newtonian fluid that can act like both a liquid and solid!
Mad Science Silly Putty
1 4oz plastic, disposable cup
1 bottle white glue - can be Elmer's or another brand.
1 small bottle of your favorite paint color
1 tsp Borax powder (grocery store, laundry detergent aisle)
2 oz water
1 popsicle stick or other expendable stirring device
Put on your apron, goggles and gas mask (just kidding!)
Mix water and Borax, stop adding Borax when it no longer dissolves in solution
Pour about 2 oz of glue in the plastic cup
Add a few drops of paint (not too much!)
Stir the paint and the glue
Dribble a small amount (start with about 1/4 tsp) into the glue/paint mixture.
Stir until well mixed
Repeatedly dribble additional Borax/water and stir until all material has reacted and you have a putty ball.
Wipe putty from stick
Let putty dry a bit until not too sticky
Play with putty (stretch, bounce, etc)
Seal putty in cup or ziploc when not in use.
Do not eat.
Mad Science presents: Sink or Swim
1 ketchup (or relish) pouch
1 Large soda bottle
1 teaspoon of salt
Water
Step 1: Fill the soda bottle with water
Step 2: Fit the unopened ketchup pouch into the bottle.
Sep 3: If the pouch doesn’t float, add 1 tablespoon of salt to the bottle. Cap and shake the bottle to dissolve the salt. Repeat until the pouch flats at the top o the bottle.
Step 4: Cap the bottle tightly; Squeeze the sides of the bottle.
