Day 1
Introduction You and your team are in the process of building a monument. On your upcoming trip to
Washington D.C. you will see many monuments. Many of these monuments are made of natural
stone. Stone and the minerals that make up these stones are all subject to the nature. On this
leg of Project 2 you will be introduced to the earth process of weathering in nature. You will
navigate the internet to discover all the elements of weathering and how they will affect
monuments made of stone.
Directions
Every group member will be given a Graphic organizer to help keep track of all the information
we will be learning about in the project. Each member is responsible for filling out their own
graphic organizer even though this will be done as a group.
Below is a list of websites that will teach you about the process of wreathing and how it affects
different rocks in nature. Throughout the your journey you will be asked to stop and complete
different labs that will supplement any of the weathering process we learn about.
Once you and your team have completed the graphic organizer and individual labs you will be
responsible for choosing what earth material (rock) your team will use to build your monument.
Step 1
Find the definition of weathering and the 2 types of weathering

Step 3
Once you have finished the mechanical weathering section STOP!!!
Go to the lab area and do Lab #’s 1, 2, and 3 on Frost action and abrasion.
Lab 1- Sugar cube shake up
Lab 2- Growing water
Lab 3- Antacid break-up
While doing the labs you should complete the observation sheets.
Once finished answer the questions on the Lab.
Step 1
Types of Chemical Weathering

Step 2
Step 3
It is time for another lab. Go to the lab area and do lab #’s 4, 5, and 6.
Lab 4- My Monument (Water and acid)
Lab 5- Steel and water
Lab 6- Clean change
While doing the labs you should complete the observation sheets.
Once finished answer the questions on the lab as a team.

Step 1
READ!!!!
There are many different types of rocks on and below the earth’s surface. All rocks are
different due to the minerals that are present in them and how they were created. The rate of
weathering is greatly affected by the mineral composition of a rock. The mineral composition of
a rock factors into both kinds of weathering, physical and chemical. Minerals in rocks that are
soft will weather more quickly than those that are harder and certain minerals are more
vulnerable to chemical weathering than others. The hardness of a rock affects the stability of
the rock. As you read the stability of a rock is one factor that helps determine the rate of
weathering. In this section you will be testing the durability and hardness of several different
rock types to decide what type of material you would use on your monument.
Step 2

Step 3
Fill in your Moh’s scale!!!!
Step 4

Time for a lab!! Safety and following directions are important in this lab.
Go over to the lab area and get a lab kit with the directions for your next lab.
Fill in your Graphic Organizer as you go.

Step 5
Now finish your project by deciding as a group which building materials you would like to use
in your monument. Be sure to include why you choose that material. Your explanation should
be at least 5 – 6 sentences.
