Then we went rock collecting!
Afterward Sam cleaned the rocks and sorted them. She was excited to find some quartz.

Some rocks are actually dried lava.
Sediment is lots of sand and mud and pieces of plants and animals.
Fossils are old animal bones in rock. The dead animal sinks into the sediment and becomes a fossil.

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.
Thanks to Hurricane Experiments for Kids for the ideas.

Hurricanes also do good. They take warm air to cold places. Brr!
The worst hurricane in the United States was hurricane Andrew. The worst hurricanes happen in the Bay of Bengal in India.
In Australia guess what they call hurricanes? They call them willy-willies.

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.
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.

In a big storm, trees fall, the waves get big and there’s lots of thunder and lightening.
A hurricane is a big storm.
A tornado is a tunnel of wind.
The eye of a hurricane has no wind inside it. The eye is dangerous because the rain and wind are worse around the eye.

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.
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.

Based on More Mudpies to Magnets
We saw mostly small, fluffy clouds but a couple of wispy clouds here and there. We also saw some mysterious wispy clouds low in the sky.
Rain: we measured 1 3/4 inches of rain in our weather station.

Guess what? There isn’t any new water on earth. Every time it rains, just imagine that it is raining last time what it rained. This is how it happens:
1. The sun heats up the water in rivers and seas.
2. Little bits of water go up into the air and turn into big clouds.
3. When the clouds get too big, they let go of their rain that goes straight into the sea.
Snowflakes come in all different shapes but they have one thing in common: they all have six points.
