Viscosity: A Physical Property of Liquid

Today in class we:
- Discussed the difference between physical and chemical properties
- Discussed the property of viscosity and the influences to the viscosity of lava: silica content and temperature

Worked on viscosity lab

Today in class students had the opportunity to work in their groups on their Volcanoes of the World Projects

- Projects are due and will be presented on Tuesday, April 22nd
- See sidebar for links to project outline

Viscosity

Today in class we:
Discussed the property of viscosity and its importance in volcanic activity
Participated in viscosity lab (see sidebar for download)

For Thursday:
Come to class prepared to do research for your volcano project

Welcome Back Students

Today in class we:
- Reviewed earthquake quizzes
- Began discussion on volcanoes: Volcanoes related to plate boundaries, hot spot volcanoes, magma vs lava

Homework:
Earthquake quiz corrections due Thursday, typed and stapled to quiz

1st period: come with prepared answers for your video conferencing questions, also have questions prepared for the Maine students
