Brainstorm

What are ways that machines make our

lives easier? (Think about the chores you

have to do every day)

Talk in your groups and come up with at

least 5 ways that machines help us.

When the timer goes off, we are going to

share out!

What are some machines we see

everyday that help us?

name and class

period on the

top of your

workbook.

This is your

journal for this

project – keep it

safe!!!

Putting the 2 ideas together…

So we have watched 2 videos that show

pretty complex systems that are made of

SIMPLE machines. But those were for fun.

How about looking at a complex system

that actually does a task?

Day 2: What is a PBL?

What is the best machine design to

move an object?

What is this?

How each day is structured

Every day you will see the driving

question and “need to know”.

The driving question for the entire

project is: How can I design and build

a machine that will move an object?

The “need to knows” are goals or

conceptual understandings that you take

away at the end of the class.

Need to Know (s) for today:

What does PBL look like in science?

What is your role?

What does my role mean to me and the

group?

The next slide has how it will look every

day:

How can I design and build a machine

that will move an object?

What does PBL look like in science?

What is your role?

What does my role mean to me and the

group?

What does PBL look like in

Science class? Project Based Learning in Science requires us to

work together to reach a goal.

◦ Collaboration is critical

◦ Working on your own is not an option

Freedom to choose

◦ The ability to design and build something totally

original. BE CREATIVE

Mistakes are a good thing

◦ They are an opportunity to learn

What is a model?

What are some examples?

Think – Pair - Share

Model (just one example)

A model is a scientific representation aimed

at making something easier to understand

or interact with.

Lets investigate the breakdown a simple

machine

Plant Quencher

Need to know

How do simple machines affect force,

distance, and direction?

How are pulleys and inclined planes

represented on paper?

Turn to the following page in your

workbook

Lets read together.

Find the simple machines in this picture.

Work in groups to circle the simple machines that

you find. When time is up, we will share out.

A timer will be set on

the board. (20 min.)

Day 4: Nov. 7 Thursday

Inclined Planes and Pulley Lab Driving Question:

How can I design and build a machine that will move an object?

Need to Know:

How does an inclined plane change the amount of force on a load?

How does a pulley change the amount or direction of force on a load?

Inclined Planes & Pulleys Lab

Purpose:

Investigate how inclined planes and

pulleys can be used to change the amount

or direction of force to move an object.

Materials:

5 Textbooks

Spring scales

Bags

Marbles

Long, medium & short ramp

Inclined Planes & Pulleys Lab

This lab is broken into 2 stations with multiple parts.

Inclined Planes & Pulleys Lab

Station One

I. Inclined Plane

a. Inclined Plane (smallest length)

b. Inclined Plane (medium length)

c. Inclined Plane (longest length)

Station Two

I. Pulley

a. Fixed Pulley

b. Moveable Pulley

c. Compound Pulley

Inclined Planes & Pulleys Lab

Instructions:

1. With your group members, carefully read each

station card. Follow each step given on the

cards and record your data in the chart

provided.

2. Once you are finished with each station, answer

the conclusion questions provided on your lab

sheet.

3. Manage your time according to the timer

shown on the overhead

How can I design and build a

machine that will move an

object?

How does an inclined plane change the

amount of force on a load?

How does a pulley change the amount

or direction of force on a load?

A note about building supplies:

All building supplies need to be recyclable-type items and need to be brought in by Monday Nov. 11.

What are acceptable items?

Day 5: Nov. 8 Friday

Blueprint design Driving Question: What is the best machine design to move an object? Need to Know: What is a blueprint? How can I design a machine that

can move an object and includes incline planes as well as pulleys?

Drawing a blueprint

Remember to refer to your

notes

◦How do you show a pulley on a

blueprint?

◦Use the steps you have already

created!

Turn to the following page

Lets read together.

Turn to the following pages and let’s

briefly discuss our expectations.

Expectations:

1. Make sure that you are

supporting your group and

fulfilling your role.

2. Remain on task and complete

the steps 1-5.

3. Both a sketch and a

description of what is

happening needs to be in each

step “square”.

4. Check the rubric to make

sure you have all of the

requirements.

You will have a timer on the board to

accomplish the following tasks.

1. Review the Blueprint Rubric (5 min.)

2. Brainstorm your group’s blueprint

design (15 min.)

3. Create the Blueprint Process – these are

the steps! (25 min.)

Before you leave:

All building supplies need to be

recyclables and need to be brought in by

Monday Nov. 11.

Your group needs to have all 5 steps

completed on the page. EVERYONE

needs to have it in their workbook.

The next step is to create a rough draft

blueprint on Monday, so be prepared!

Day 5: Nov. 8 Friday
