Remember high pressure systems always moves toward the low pressure systems! This is a picture of a land breeze.

At night time air over the land is cooler and creates an area of high pressure. The cool air moves toward the water, producing a land breeze. Air over water is warmer and creates an area of low pressure.

Just the opposite happens during the day. Air over water is cooler and creates an area of high pressure. The cool air moves toward the land, producing a sea breeze. As this warm air rises (as is the case when it runs in to the coast range here in Oregon) it creates an area of low pressure over the land.

Today we did a lab on convection currents using our convection tubes and some ice, hot water and a punk stick. We observed the smoke as it traveled through our convection tubes and its relationship to the hot water and/or ice. This was also an assessment on how students use make observations and predictions. I purposefully used hot water, rather than a candle to see if students would “call” me on my mistake. No one actually said anything and tomorrow I will solicit responses on whether or not anyone noticed this, but did not speak up!

Be sure to check the NOAA site or the local news on the earthquake that happened and the tsunami watches that were posted for some of the Oregon Coast.

We will continue studying weather systems next week.

Wind, air pressure, and convection currents will be the focus of the labs next week also!

NO HOMEWORK THIS WEEKEND!

Hello there!

I want to welcome you to the class blog for 6th, 7th, and 8th grade science at Arts and Technology Academy!

This is a work in progress, but will soon have a wide array of information that you (the student) your guardians/parents, siblings, uncles, aunts, and grandmothers can access anytime.

Mr. Morphis
