What happens if a plant does not get sunlight? As a home school science lesson for my son, age 10, we performed an experiment.

Who is the artist?  How did they get their impression?

Who is the artist? How did they get their impression?

Many reports lack scientific evidence or even basic citations of sources used. They use deceiving words that sound scientific, but they are not scientific.

The Scientific Method:

  • observable
  • testable
  • repeatable
  • falsifiable

When you see reports presented as “science”, test them to see if they offer convincing evidence that would meet the above criteria.

Be careful what you believe! Demand evidence!

In this home school lesson, we see how blue dye is soaked up by a celery stem and brought up to the top of the stalk.

We used a magnifying glass, small jar with water, food coloring, and celery.

Conclusion

Even without roots or leaves, the stem performs work, pulling liquid up against the force of gravity.

I did an experiment, trying to clean metal in a new way (for me).  I burned some potatoes to the bottom of a pot and it needed to be cleaned.  I made the mistake of not putting in enough water and the potatoes burned at the bottom.  It was a mess and needed to be cleaned.  I decided to try an experiment and brought the camcorder with me to share the results.

The results of using hydrolysis to help clean the burned pot.

Acid can release electricity from metal.  What is an easy-to-find source of acid?   Tomatoes!

VIDEO

The video above shows how an LED and a buzzer are powered by a tomato battery.  It’s just two different metals dipped into mashed tomatoes.  It even helps charge a AAA battery.

How does this work?

Many people have tried adding Mentos to Diet Coke for a fun explosion of foam. Does only Diet Coke work or can another beverage work as well? Could Diet Pepsi work with Mentos to make an eruption?

My two kids were interested in the experiment, so for fun, we tried making our own volcano with Mentos and Diet Pepsi. It works!
