21_22 Earth Science Portfolios (1)

21/22 Earth Science Portfolios 1st Semester: 2nd Semester Unit 1 Star Composition Lab: In this lab, you are only required to complete part one . Some of the links are dead ends, please review the powerpoint and watch the video for directions and guidance to the working links. Directions Video (Alcala) Directions Powerpoint Directions Document Lab Document Unit 7 Geologic Age Lab In this lab you will be finding the half life of a fictional element. It does require for you to have 100 of some small item, sugar cubes are listed in the lab but I find pennies to be easier and more available!! For a container you can use a shoebox as listed in the lab, I used a large tupperware for my sample data collection. If you are unable to find 100 of a single small item, you can use the sample data provided at the end of this portfolio document. Lab document Sample Data document Geologic Lab LiveLesson workshop Not used for 21/22- Unit 3 Thermal Convection Lab: presentation Follow the directions in the lab and use the presentation to guide you through the data collection and expectations Unit 3 Carbon Cycle Changes Lab Note: don’t forget to save and rename the worksheet to your computer before you begin working in it. The worksheet is on p.4 of the activity, and is titled “Comparing Carbon Loads”. Before you start this lab, I suggest watching this supplementary video from NASA about the carbon cycle. In this lab you are simulating the carbon cycle using random rolls of a die. Carbon does not move through every part of the cycle at the same rate, known as residence time , so rolling the die and tallying your results is designed to simulate the time a carbon atom spends in any given part of the cycle. Carbon reservoirs, such as the ocean, atmosphere, rocks, and organic sediments (fossil fuels), hold carbon for longer periods than other stops in the cycle, like organic matter (living things). You will collect data (rolling the die), graph your data, and evaluate it. The goal is to examine the changes that have occurred in where carbon is located within the cycle since the onset of the Industrial Revolution. Here is Ms. Alcala’s video that demonstrates how to do the lab! Modified Lab Document Unit 4: Rock & Mineral Properties Lab The goal of this lab is to determine which mineral is better for the tasks they are used for, based on physical properties, cost of extraction, and environmental cost. This lab requires you to submit 2 parts : 1. The resource properties and use data table and 2. The power point or research paper presenting your data and conclusions
