The Ups and Downs of Air Pressure!
- A cup completely full of water
- One straw cut in half (first half must stick out of the water by only 1/2 an inch)
- trash bag
- Place the trash bag over the table and put the cup on top.
- Put the longer straw in the cup of water.
- Move the cup to the edge of the desk.
- Squat down so your eyes are level with the cup.
- Using your fingers to hold the small straw next to the edge of the cup, blow through the other straw at an angle towards the top of the straw in the cup. (Angle the straw upwards so that the air coming out of it passes right over the top of the straw in the cup.)
- Keep blowing and blowing over the top of the straw in the cup.
- "The water will begin to bubble and will eventually spill out of the cup."
- "Nothing will happen to the water."
- "The air will make a whirling sound, but no water will come out of the cup."
- A stream of water squirted out of the straw that was in the cup.
- When the students blew air over the top of the straw, the moving air could not press down as hard on the water in the straw. The air over the rest of the water in the cup was not moving, so it continued to press down on the water with its full pressure.
- Since the water in the cup was being pressed down harder than the water in the straw, water was forced up and out of the straw!
- This is a lot like what happens to a bird's wing.
- Just as the difference in air pressure over the straw and the rest of the cup lifted water out of the straw, the difference in air pressure between the top and bottom of a bird's wing lifts the wing into the air!

3, 6, 9! It's Counting Pattern Time!
This week in math we have been reviewing place value, as well as counting patterns! Yesterday, we broke out our colored pencils and hundreds charts in order to obtain some hands-on understanding! As each child skip counted by 3's and 4's we also noticed some pretty neat patterns. It was such a sweet time when students started recognizing spatial, visual, and numerical patterns! Below are pictures of the hundreds charts we completed!
