Experiment: Hurricane Strength

Monday, September 17th, 2012

1. What Did We Use:

water, bowl, paperclip, string and wooden spoon.


2. What Did We Do:

We filled the bowl with water and we stirred it with the spoon, then took the spoon out and put the paperclip on the string in, to see if it moved or not.

3. What Happened:

The paperclip moved through the water after we had stopped stirring.

4. What Did We Learn:

We learned that hurricanes have momentum even after they stop spinning.

Addendum: we also added food coloring to watch how “clouds” swirl in hurricane wind.

Tornado in a Jar

Friday, September 14th, 2012

What Did We Use:

dish soap, a jar, vinegar, food coloring and a teaspoon.


What Did We Do:

We filled the jar with water and added 1 teaspoon of dish soap, 1 teaspoon of vinegar and a drop of food coloring. Then we put the lid on the jar, and we shook it up.


Shake it up

What happened:

When we shook the jar, a funnel appeared for a few seconds.

What did we learn:

If you shake it up and down it won’t work. It will only work if you shake it around and around.

Experiment: Let’s Dew It

Thursday, August 30th, 2012

What Did We Use?

Water, ice cubes, a jar, a glass and humidity.

What Did We Do?

We put ice cubes in the glass and the jar and filled them with water. We put the jar outside but we kept the glass inside.

What Happened?

The jar outside got more dew and it got faster because it was hotter outside than inside.

What Did We Learn?

We learned that the jar got more dew because there was a 7 degree difference outside (hotter).

Fact: The hotter the air is the more water vapor it can hold.

celery, glass of water, red food coloring.

2. What Did We Do?

Experiment: What’s that Object?

Wednesday, August 1st, 2012

1. What Did We Use?

We used balls, apple, lime and a shell. We also used a hat, a book, a pencil and a bandana. Also thick and thin gloves.

2. What Did We Do?

We put the things on a tray and put the bandana around Mom’s head so she couldn’t see. She tried to feel the stuff on the tray, and see if she could tell. We also tried with gloves–really thick ones. Then we tried with thinner gloves.

3. What happened?

Mom did very good. She mostly got them all right, but some wrong with the thick gloves. She thought they were all balls. With the thin gloves, however, she did better.

4. What did we learn?

We learned that feeling is much better at telling you what you’re touching than you think.

We then repeated the experiment with Dad:
