Objectives:

Objective - Students will be understand what power is, create a question and investigate it.

Sub Objectives:

SWBAT understand what power is.

SWBAT create a question and investigate.

SWBAT take part in a board meeting.

Today we will understand what power is, and what watts are, so that we can apply our understanding to create a question to investigate.

I know I succeeded if my team was able to collect data and participate in a board meeting.

Agenda

Teams will…

  1. What is power?
  2. How is power measured?
  3. Create a question to investigate
  4. Conduct investigation
  5. Collect data
  6. CER
  7. Board meeting

Intro/Driving Question/Opening

Today we are going to be looking at a STEM lesson. We are focusing on two areas of STEM, Science and Math

How have/can you use science in STEM?

How have/can you use math in STEM?

Based on the title, how can we use science and math together?

What is something we can not live without?

Power and Energy

10 of 30

What is POWER?

11 of 30

Power…

is the rate of producing or consuming energy

12 of 30

What is energy?

13 of 30

Energy…

is the ability to do work

14 of 30

How do power and energy work together?

15 of 30

Energy is the total amount of work done, and power is how fast you can do it.

16 of 30

How do we experience power?

LIGHT

HEAT

MOVEMENT

18 of 30

How do we measure power?

19 of 30

What do these things have in common?

What does each itm use as a unit of measurement?

20 of 30

This is an electricity usage monitor

21 of 30

What unit of of measurement does power use?

22 of 30

Watts

What is a measure of the rate of energy transfer over a unit of time

Hands-on Activity Instructions

Come up with a question that you will use to guide you investigation.

Two things to focus on:

Time of use

Watts

Then create a table for the data you will be collecting.

24 of 30

Hands-on Activity Instructions

Everyone in your table must test out at least one item and use the electricity usage monitor.

You will only have two minutes to use each item and collect data.

25 of 30

CER

Write a CER paragraph answering the question you and your team created. Then write it on your whiteboards.

Rewrite question

Claim

Evidence

Reading

26 of 30

Board Meeting

Teams will stand together to read their CER to the group.

Person 1 Read questions and the Claim

Person 2: Read your Evidence and explain table if they have it

Person 3: Read your Reasoning

One person from the team that is next must use the chart to add to that teams

27 of 30

Board Meeting

Comprehend

Can you explain more about…?

Are you thinking…?

Why do you think…?

How do you generate your claim?

What reasoning can you support the evidence?

Critique

I respectfully disagree that …because…

Your reasoning does not make sense to me because…

I understand why you say that, but I do not agree this part because…

Construct

I agree with your ideas because…

I would like to add on….; I would like to revise my claim because….

If you revise/ add this…., the argument would make sense to me.

Express

I noticed…; I observed…; I wonder…..; I think….because

My data shows….

Assessment

Transform

What would you have done differently in your investigation?

Reflect

Apply

What other things would we investigate based on this information?

Differentiation

Remediation

  • Give student only 1 item per power type
  • Give student more time
  • Data take handout for them to fill in
  • CER sentence started

Extension/Enrichment

  • Give student more items to use
  • Give students items that product the same type of power
  • Give student more than 2 minutes
  • Have student write their CER independently
  • Remove the board meeting sentence starter and have them come up with their own
