Students will measure and analyze features of two different species of trees by using their cross-sections (cookies). Further analyses will allow students to graph their results and apply the knowledge gained to an understanding of tree growth, health and diversity.
Objectives
Students will use and understand the following terms: radius, diameter, circumference and area of a circle.
In this lesson, students will play a fun board game that teaches about the sources and types of some air pollutants, and how they affect the health of both people and the environment. Students will learn that not all pollutants are greenhouse gases. This game can be a lead-in for a discussion about climate change and what people can
Working in groups, students will use common materials to create layers of snow and ice representing thousands of years of stratification. Groups will exchange their ice layers and extract core samples to analyze them.
Objective
Notice the phenomenon of stratification.
Notice that layers can tell a story of change over time.
