Energy Unit

Wednesday, August 21 st Agenda: Continue Rituals and Routines Take Energy Unit/Chemical Interactions Diagnostic. Discuss reasons for diagnostic and what will be done with results. Assign homework books and make first packet. Homework: Section 1 homework packet.

Thursday, August 22 nd Please write on loose leaf until we receive notebooks. LT 1: I can identify the different forms of energy. NB 1: What is energy? Agenda: Collect homework Discuss what you believe energy is and write an initial idea on log. Go over energy handout. Homework: NONE

Friday, August 23 rd LT 1: I can identify the different forms of energy. NB 2: Identify one form of energy and where it can be seen your life. Agenda: Work in groups to identify forms of energy seen in various photos. Complete the identification sheet as you work. Share results with peers. Homework: NONE

Monday, August 26 th LT 1: I can identify the different forms of energy. LT 2: I can identify where energy conversions occur in a system. Agenda: Go over learning log feedback. Officially define the term energy. Discuss the conservation of energy. Try to identify where energy conversions take place in a sample activity. Homework: Roller coaster Energy reading and questions.

What is Energy? We have identified many forms of energy. We know that energy can be stored for future use (potential) or in motion (kinetic). But what IS energy? All energy allows work to be done or causes a change. Therefore, we define energy as the ability to do work. Page : Energy is the ability to work.

Energy Flows A major idea in science is the Conservation of Energy. What this means is that energy is neither created or destroyed. It simply converts to different forms. Energy does not get “used up,” it gets changed from one form to another. In the case of chemical potential energy, sometimes some help is needed to cause the conversion. This help is provided in activation energy.

Identifying Energy Conversions Today you are going to work with a bag of materials. You have one goal: Identify any energy conversions that you see take place while you play with the materials. You will be sharing your findings with the class tomorrow. Please turn to page 4 of your notebook. We are going to create a data table to record observations.

Rules During the exploration: 1.Treat the equipment respectfully and gently. 2.Stay at your own seat. 3.Work only within your group with the assigned materials.

Tuesday, August 27 th LT 2: I can identify where energy conversions occur in a system. Agenda: Go over homework. Go over energy conversions from yesterday. We will make any changes in notebooks. Define Conservation of Energy in notebooks. Energy conversion practice sheets. Homework: NONE… but, you should begin reviewing flashcards nightly.

Roller Coaster Energy Questions What makes a roller coaster move? How does a roller coaster gain gravitational potential energy?

Roller Coaster Energy Questions At what point on the track is the gravitational potential energy greatest? What happens to the gravitational energy as the roller coaster car beings to go down the first hill?

Roller Coaster Energy Questions Not all energy is transferred to the kinetic and potential forms. What does some of the potential and kinetic energy also get transferred into?

Conservation of Energy P 6 The Law of Conservation of Energy: Energy is neither created nor destroyed. Energy is converted from one form to another.

Wednesday, August 28 th LT 2: I can identify where energy conversions occur in a system. Agenda: Mini Assessment over LT 1. Discuss variables. Define in notebook. Begin collecting data for Energy in a bouncing ball. Homework: Energy and Power sheets. These are due on FRIDAY

Variables Variables are what get changed in an experiment. Only ONE variable should be changed in an experiment. That variable is called the independent variable. The variable that gets changed by the investigator should affect one outcome, called the dependent variable.

Variables P 8 Independent Variable: The variable changed by the investigator. ( I change it ☺ ) Dependent Variable: What gets affected by the independent variable.

Variables Ind. Variable Dep. Variable Number of calories eaten Weight Minutes of daily study Test score Number of minutes practicing free throws Free Throw percentage at games

Thursday, August 29 th LT 2: I can identify where energy conversions occur in a system. LT 3: I can graph independent and dependent variables. Agenda: Return and reflect on mini-assessment. Graph data from energy in a bouncing ball. Complete the Results section. Homework: Continue working on packet.

Hypothesis Write a hypothesis as an “if, then” statement.

Identify the independent and dependent variables

Friday, August 30 th LT 2: I can identify where energy conversions occur in a system. LT 3: I can graph independent and dependent variables. Agenda: Complete Conclusion section Complete CRE Go over homework. Homework: NONE. Enjoy the Labor Day Weekend!!

Tuesday, Sept. 3 rd LT 2: I can identify where energy conversions occur in a system. LT 3: I can graph independent and dependent variables. LT 4: I can explain the Law of Conservation of Energy. Agenda: Continue discussing Evidence/Reasoning Practice LT 2, 3 and 4 on worksheets Homework: NONE. Test next Tuesday over LT 1 – 4.

Wednesday, Sept. 4 th LT 3: I can graph independent and dependent variables. LT 4: I can explain the conservation of energy. Agenda: Roller Coaster multimedia demo Practice LT 3 and 4 Homework: Study Guide
