Do your kids have a stash of Halloween candy? What a great time to do fun candy science experiments!


If you have any wintergreen LifeSaver® candies in the hoard, here is a quick way to make lightning in your mouth with candy.

Candy Chromatography
Separating the colors in MandM’s or Skittles® using paper chromatography is for older kids. It takes a bit of time and patience.

A simple experiment with Candy Chromatography uses water to make spots on a coffee filter.

Dogged Research has an extensive research paper that covers many of the issues you may encounter. If you have time, you’ll learn quite a bit.

Chocolate science is always fun. This chocolate experiment is for older kids interested in food science. It does require heat and special ingredients.

Steve Spangler’s Science has several fun, candy-related experiments.

1. This experiment uses pop rocks popping candy and soda to explore how this candy gets its bang.

2. Mentos candy and diet soda causes a big splash.
Here’s why it works.

3. More candy science ideas

If you didn’t get enough candy last night, try Making Rock Candy. Use the recipe to make some sugar crystals.

We are in a bit of a rush today. We've been promised the opportunity to play with a fabulous microscope camera device. Hopefully we'll be able to show some incredible photos for bug of the week next week.

Have some sweet success with candy science today.

After several months of heavy construction, the new Growing With Science website is ready for reveal.

The website has science activities organized by age and theme. I've tried to keep the pages simple and direct. There will probably occasionally be a few typos and oddities as I develop it over the next few months. Let me know if you have major difficulties with anything.

Here is the URL address:

The first theme is growing plants from kitchen scraps, or other items found around the kitchen. Most of these activities can be carried out indoors for little or no cost. Simply click on the science activity link and then pick one of the links listed under your child's age level.

The second theme is Weather for Kids. If you like pretty photographs of clouds,  visit the cloud classification activity and try the slide show.

Hope you find a fun activity that you just have to try.


It’s cabbage looper season here again. In some places cabbage loopers might be considered to be pests, but in our yard they are considered to be pets. They are hardy, will eat a wide range of foods, and they show up every year.

The looper gets its name from the fact it “loops up” in the middle while walking. The caterpillar has two sets of appendages. Its six true legs are right behind the head. Towards the rear is another set of fleshy, wider appendages called “prolegs.” Scientists don't count the prolegs, so the caterpillar still has the six legs characteristic of insects.

The caterpillar holds on with the true legs and brings its back end forward. The prolegs meet the true legs, and the back forms a loop. Then it releases the true legs. The head and front spring forward. The looper holds on with its true legs and the process repeats.

This one was nibbling my mint, but I'm not too concerned. The mint is prolific and the caterpillar has a lot of enemies. It is eaten by birds, wasps and parasitic flies. So, loop on little buddy.

Edit: The cabbage looper moth is featured in a later post.
