Forest Locations
We will begin at the science center-glacier rock-upper reservior- Aleck Meadow. The bus will pick us up at Aleck Meadow.
Materials
In order to complete this lab in the forest the Â鶹 will need clip board, pencil, colored pencils. The lab form is where they will record the information that they are learning from the forest.
Schedule
The trip will begin at the science center. As a group we will travel to toward upper meadow. We will stop at the glacier walk along the way. At this point we will stop and discuss how ice and glaciers have shaped the earth. The Â鶹 will fill in the first part of their lab sheet. As a group we will then travel towards upper reservoir. Here the Â鶹 will look for rocks that have been eroded by water. Finally, we will travel to Aleck meadow. At Aleck meadow we will then look for rocks that have been eroded by land. At Aleck meadow we will have lunch and then the bus will pick us up there.
Pre-Forest Activity
Before entering the forest we will work with the Â鶹 on learning about erosion and the different types of erosion. Teachers should complete an erosion interactive notebook with the Â鶹 in the classroom. This interactive notebook will teach them what erosion is and how it affects our earth. The Â鶹 will learn about the three different types of erosion, water, ice and land erosion. They will learn about how these different environmental features affect the shape, size, texture and structure of a rock. The interactive notebook will allow the Â鶹 to draw pictures, take notes, learn definitions, read articles and look at pictures to help them understand the erosion process. The interactive notebook can be purchased on The teacher should also read stories and watch videos about erosion. This will help the Â鶹 gain a basic understanding of what erosion is and how it affects the earth. The lab activity in the forest will reinforce these ideas for the Â鶹 to gain further understanding.
Here are some resources the teacher may use to teach erosion in the classroom before attending the trip.
Before leaving for the trip teachers should also make sure that they prepare the Â鶹 for what to expect in the forest. Instruct the Â鶹 to wear sneakers and comfortable clothing as you will be walking about a mile while in the forest. The Â鶹 should also pack a lunch that they can eat while in the forest (sandwich and chips, no glass bottles). The Â鶹 should also pack a water bottle so they stay hydrated in the forest. I would also make sure to tell the Â鶹 that there is not bathroom in the forest. They need to use the bathroom before we leave. You must also ensure that the Â鶹 understand that they must stay with the group. If Â鶹 were to fall behind or go ahead of the group they risk getting lost in the forest.
Forest Activity
While in the forest the Â鶹 will be looking for rocks that show evidence of erosion. They will have to identify what type of erosion the rock is. We will begin our trip at the science center. We will begin to walk together towards upper reservoir. As we walk towards upper reservoir the group will stop at the glacier rock. At the glacier walk the teacher will stop and talk with the Â鶹 about how this rock is very different from other rocks in the forest. The teacher will explain that that is because this rock was brought her by a glacier. The teacher will prompt the Â鶹 to then identify that this means that the rock was eroded by ice. The Â鶹 will be given their lab sheets. On the lab sheet they will have to find rocks of the three different types and record them on the sheet. They will draw a picture of the rock in the box. They will then describe the rock by answering the questions on the lab sheet. Once all the Â鶹 are done we will begin to move toward upper reservoir.
Once at upper reservoir the Â鶹 will again look for rocks that have been eroded. The teacher will talk to the Â鶹 about what type of erosion the Â鶹 think they will find there. The Â鶹 should be able to understand that they should be looking rocks that have been eroded by water. The teacher will help picks some rocks out of the water that have been eroded by water. The Â鶹 will look at these rocks and we will compare how they look to the rocks that were eroded by ice. The Â鶹 will then fill in their lab sheet based on the rocks they find. Once the Â鶹 are done we will finally travel together to Aleck Meadow.
Once at Aleck Meadow we will look for rocks that have been eroded by the final type of erosion, Land erosion. The Â鶹 will look around and find rocks that have been eroded by land and nature. The Â鶹 will find the rocks and then fill in the lab sheet for their final rock. Once they have all completed the sheet we will have discussion about the rocks that we have found. The teacher should ask the Â鶹 the following questions:
How do each of the rocks differ?
Why are they all shaped so differently.
What do you think caused these different types of erosion?
Predict what you think these rocks will look like in 20 years?
How does nature and the environment affect erosion?
What could we do to help slow erosion?
The Â鶹 will end the lab by completing the lab report on one of the rocks they found in the forest. They will answer questions about erosion and how the rocks they found are evidence of erosion.
Post-Forest Activity
Upon returning to the classroom we will discuss what the Â鶹 learned on their trip. In order to expand this activity and have the Â鶹 work on ELA skills the Â鶹 will write an erosion story for their rock. They will pick of the rocks that they drew from the forest and they will write a story about how it eroded. They will have to tell about how it was shaped and where it was located long ago. They will then have to explain how it traveled and how this traveling caused erosion. They will then have to explain how it has been eroded over time to determine the current shape and size of the rock. For Â鶹 who are higher level learners you might challenge them to write about how it got certain scratches or chips in the rock.
Assessments
The student’s data sheet will serve as a form of assessment. They should be able to identify the different types of rocks and erosion. That will indicate that they understand erosion. Their erosion story written in the classroom will also serve as an additional assessment piece. It will indicate if the Â鶹 understand the process of erosion.

Curriculum
Within the second grade curriculum the Â鶹 will be learning about weathering and erosion. The Â鶹 will learn about how erosion affects the shape of the earth. They will be reading texts and reading stories about how erosion affects the earth. This activity will build on this.
Objectives
Given an outdoor experience, Students will be able to identify different land and rock structures that have been affected by erosion.
Background
In order to participate in this lesson the Â鶹 will need background knowledge of erosion. The Â鶹 should know what erosion is, how it affects the earth and the different types of erosion. The Â鶹 will need an understanding of the vocabulary: erosion, weathering, wind, glacier, abrasion, pressure, runoff, Sedimentary rocks and geologists.
Safety Concerns
The Â鶹 should wear appropriate clothing and shoes. They should also were bug spray applied at home so that they do not have any reactions to the elements in the forest. They should also bring any medication that they may need.
