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

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:
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!
The plant stem pulls water and minerals to the leaves.
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.
Even without roots or leaves, the stem performs work, pulling liquid up against the force of gravity.
Miffy is a picky cat, often refusing to eat top brand cat food, including Fancy Feast.
I took a gamble and bought some Cesar brand moist dog food from Walgreens. Let’s see if she will eat it…
I made my first batch of homemade toothpaste. It was much easier than I expected.
This is an experiment generating electricity from scrap metal.
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 original video shows a group of experimenters from Canada that are making Hydrogen in the form of HHO using electrolysis. Something goes terribly wrong.
The solar lights on my property have been dim or have been completely off at night. Maintenance can be done on these lamps to get them working again.
Make Your Own Air Battery
Making a waffle out of sodium acetate trihydrate. This is the same stuff that makes up “hot ice” and heating pads.
How is the liquid made?
Acid can release electricity from metal. What is an easy-to-find source of acid? Tomatoes!
The video above shows how an LED and a buzzer are powered by a tomato battery. My homemade battery was made from two different metals dipped into mashed tomatoes. This setup had low power output, but it was also able to help charge a AAA rechargeable battery.
How does this work?
Can a Peltier cooler be used to extract moisture from the air using off-the-grid power?
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!
