Renewable and Non Renewable Resources TODAY Fossil Fuels
Renewable and Non. Renewable Resources TODAY: • Fossil Fuels and Renewable VS Non-Renewable • Renew-A-Bead Activity
Objective and goal for today: Objective: determine the difference between renewable and non-renewable resources Goal: Have you, the students, understand the long-term value of renewable resources.
What are Fossil Fuels? Three Types: 1) coal 2)oil 3) natural gas Come from the organic remains of prehistoric organisms
How are they formed? Stages: Plant uses energy from sun to form sugars and carbohydrates (GROWTH) Layers of decomposing plants and animals are buried and crushed by enormous mass of earth, creating intense heat and pressure. Plant dies and its remains settle on ground (can also be on swamps, lakes, and seas). After millions of years of heat and pressure, the material in these layers turn into chemicals called hydrocarbons. Over time, layer upon layer of these remains accumulate into forms that we can harvest. Hydrocarbons can be solid, liquid, or gaseous.
What kind of resource do you think fossil fuels are? OR Non-Renewable? How. Renewable would you define a Non-Renewable Fossil Fuels take. Resource? millions of years to form and that makes them Non-renewable.
What then is a Renewable Resource? Examples? Lets come up with a definition?
Renew-A-Bead Activity Objective: to experience how long a Renewable resource can be used in comparison with a Non-Renewable resource. 1. Split into groups of about 3 2. Collect one bag of beads and one set of recording sheets.
Group 1 = 90 grey beads 10 yellow beads Group 2 = 80 grey beads 20 yellow beads Group 3 =70 grey beads 30 yellow beads The beads represent Energy Grey = Fossil Fuels (non-renewable) Yellow = Renewable Energy sources
Simulation 1: yearly consumption of energy at a constant rate. 1. One person pick out 10 energy beads – Without looking! Random! *These 10 beads represent energy used in one year. 2. Record the grey and yellow beads on the Data Collection Sheet. REMEMBER – the grey beads are Non-Renewable therefore you cannot return them to the bag. White beads are renewable therefore they can be returned to the original bag.
3. Another person picks 10 beads out of the bag to represent energy use in YEAR 2. *Fill in the number of Grey and Yellow beads *Remember to return the yellow beads to the bag 4. Repeat the process until either all the grey beads are used OR 20 years have passed.
Simulation 2: Yearly consumption of energy at an increasing rate. **In this simulation we are acknowledging the fact that energy consumption grows each year 1. Repeat the same process from simulation 1 BUT each year increase the energy use by picking out 5 additional beads. 2. Record the information on the data collection sheet.
