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 http://www.kidscantravel.com/familyattractions/caperoyal/funstuffkids/index.html Step 2 Types of Mechanical/Physical Weathering http://library.thinkquest.org/20035/chemical.htm Pictures of Mechanical/physical weathering http://marlimillerphoto.com/mechanical.html 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 http://library.thinkquest.org/20035/chemical.htm Pictures of Chemical Weathering http://marlimillerphoto.com/chemical.html 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. Neat Pictures and video on weathering http://science.nationalgeographic.com/science/photos/weathering-erosion-gallery/#/baffinisland_832_600x450.jpg http://www.youtube.com/watch?v=a5qRnbhtako 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 Building Material Composition http://www.ehow.com/info_8219343_type-stone-used-make-monuments.html http://www.es.ucl.ac.uk/schools/Pancras/rocks.htm Step 3 Fill in your Moh’s scale!!!! Step 4 http://www.youtube.com/watch?v=VfZ1kP4ErKc&feature=related 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. Lab 7 http://www.mineralszone.com/stones/natural-stones.html http://www.minerals-n-more.com/Granite_Info.html 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.
