Kids Science Website Review

My six year old and I were on a mission to find a kids website that we could learn more about science. We finally found one called Zoom by PBS kids. Click here to check this website out.  The newest one is the Saltwater Tester.

  • 9-volt battery
  • buzzer
  • 2 Popsicle™ sticks
  • aluminum foil
  • water
  • saltwater


Check with a grown-up before you begin.

  1. How can you tell if water is salty? You could taste it – or you could use a saltwater tester!
  2. A saltwater tester uses electricity to tell you if water is salty or not. Here’s how to make your own.
  3. First, cover two Popsicle™ sticks with metal – the ZOOMers used aluminum foil.
  4. Then, get a buzzer – you can buy one at an electronics store – and tape the red wire of the buzzer to the positive end of the battery. The positive end will have a plus sign on it.
  5. Next, tape one foil-covered Popsicle™ stick to the black wire of the buzzer. Tape the other one to the negative end of the battery. The negative end will have a minus sign on it.
  6. You can see if your tester is working by touching the metal together. This will complete the circuit and make the buzzer buzz. If it doesn’t buzz, check your connections to make sure everything is taped together in the right way.
  7. Now to use your saltwater tester, put just the tips of the metal in saltwater, about an inch apart. Make sure the two metal parts don’t touch. The saltwater will act like a wire, connecting the metal sticks, completing the circuit, and making the buzzer buzz.

Science Experiments for Kids: The Candy Project

Also visit website:

Instead of eating their treats for being good at school we decide to do a little experiment.  In this experiment we combined each of our candy choices into separate jars filled with hot water.  Austin had his 3 whoppers and Cole had his pepperment ( the kind that is pure sugar 😦 ). 
We watched until both jars had no candy left and it was just dirty water.
Then, we tried to use a coffee filter to filter the candy water into another jar.  This didn’t work that great because mine children were just not patient enough and we kept busting the filters when pouring too fast so, I took a paper dinner knapkin and used it instead.

What we noticed was that the pepperment liquid moved faster through the filter than the chocolate liquid and that because we used a filter the water was cleaner.

I also explained that this was almost like when we use a air filter for the air conditioner and how once it is filtered through we may not get the best air possible but it is much better than if we didn’t use one at all.

Both of my children loved this experiment.  Cole tried to drink his water but I was able to stop him although it wouldn’t have hurt him to do so.

During our different experiments Austin came up with the idea of making a journal to keep up with our fun experiments.

What is a fun experiment that you have tried lately?  Did you try this experiment with your child?  If so, what was the outcome?
