illustrating surface tension with pepper

1-2-3 Come Do A Pepper "Germs" Experiment With Me

Here's a quick, easy & super-fun little experiment you can do with your kiddos.

It's sure to have them saying, "Can we do it again!"

pepper germs and soap experiment about surface tensionI've compiled this activity in a FREE packet, so that you can easily duplicate and extend the lesson.

As parents and teachers we are constantly reminding children to wash their hands, especially now since the Corona virus crisis.

Children look at their hands and don’t really “see” any germs, so if they can’t see anything on their hands, they naturally conclude that their hands must not really be dirty, so why bother washing.

When I was in school, “surface tension” was explained to us with a “pepper experiment”. The result of the demonstration is truly amazing, and provides the perfect illustration for “germs fleeing soap”.

This experiment has the “Wow!” factor, while still being super-simple, plus you have all of the ingredients at home.

Pepper Experiment IngredientsYou’ll need:

  * ground pepper
  * a bowl or plate
  * a cup of water,
  * a paper plate,
  * a tissue and
  * some dish soap.

You can also use a measuring cup instead of a plastic cup to hold your water. Because a measuring cup has a handle, this could be easier for little ones to hold on to.

Watch my VIDEO for specifics, then use the FREE packet for your finishing touches.

I’ve included my "script" plus the poster, so you can use it in your own demonstration. There’s a black & white version for children to color as well.

However, to extend the lesson for older students, have them look up the definition of surface tension, then for writing practice, as well as some data analysis, have students fill in the “Here’s What Happened” worksheet, keeping in mind their findings about surface tension.

I’ve included a surface tension explanation, which you can also share with them.

If your students are like mine, they are extremely interested, and excited about doing hands-on science, so run with it. For added fun, and further exploration you can use the “Does It Make a Difference?” extension activity

For example, “Does it make a difference if you use another spice other than pepper; hot or cold water; or a different container?” etc.

I’ve done all these additional “extras” & include my findings, along with photographs in the FREE packet.

Children color, cut & hang on their doorknob.
