E1: Earth Systems

After learning about the importance of clean water and different types of filters, students engineer their own water filter.

This lesson allows students to explore why volcanoes are shaped differently and why they erupt differently. Students will investigate viscosity, silica content of igneous rock samples, and perform

Students identify the problem with drinking water contamination due to pesticide, prescription medicine, and hormones. They design solutions for a real-world problem that negatively affects the

Including themes of natural resources, art, and geography; this engineering lesson introduces students to the idea of mass conservation. While using the phenomena of the water crisis in Arizona,

In this lesson, students will learn about Wilson Bentley, the "farmer scientist" who pioneered photomicrography to photograph snowflakes and share them with the world. Students will then design and

Students in 4th grade learned about natural disasters through this interactive STEM lesson focused on the creation on a 'tsunami-proof' home. Students used the Engineering Design Process to create a

Students will learn about water availability in Arizona and design and build a prototype/model of a rain-catchment/recycling system to provide water for a school garden.

How old is Earth? How big is 1 million years compared to 1 billion years? Students will use three models to organize geologic time and practice cross multiplication to solve for a variable.

Students learn about the Colorado River watershed and the impact of water rights and usage. They will read about the past and present water flow data, build a model of the watershed, calculate data
