DIY Science Kits for Ages 7-10

My friend, Jen, asked  me about Chemistry kits, like this one.  I do not think these types of kits are a good value.  Instead, make your own kit: plastic beakers and cylinders, test tubes and rack, craft sticks to stir, medicine droppers, a thermometer, safety goggles, and household chemicals.  Save small plastic containers.  Have your child write the chemical name on the container and fill them with baking soda, table salt, etc.  I use plastic coffee containers to hold chemistry kits for kids.

  ACS has Inquiry in Action chemistry lessons for Grades K-5.  The fifth grade lessons have simple experiments which use household chemicals: isopropyl or rubbing alcohol, salt, detergent, Epsom salts, baking powder, and baking soda.  ACS has middle school lessons, such as Forming a precipitate.  This lab requires ammonia, Epsom salts, sodium carbonate Washing soda, and copper II sulfate crystals.  (Check Amazon to compare prices.). Here is another lab which uses copper II sulfate and peroxide.  Use the copper sulfate to make crystals. 

Red cabbage or red cabbage powder can be used to test the pH of washing soda, detergent, peroxide, baking soda, etc.  Frugal Fun has more ideas of household materials to test.  If you want to buy one kit, buy Fizz Wizard & Jammin Jelly.  Kids love these experiments!  I save and refill these small containers.

When you look for science experiments, stick to safe sites: Steve Spangler, ACS, Frugal Fun, or Science Bob.  Be sure to follow their instructions.  Have a blast!
