Students Will Be Able To (SWBAT):Define: Hypothesis, Null Hypothesis,

Procedure, Opinion and Bias

Develop a hypothesis using “If… then…because..”

Develop a null hypothesis using “If… then…because..”

Essential Question: How can we make engines more efficient?

Do Now: Using the number that you were assigned please retrieve your assigned textbook.

Journal Entry- Please turn to page 5 in your blended Science booklet

Using a dictionary define the following words:

Hypothesis Null Hypothesis

Procedure Opinion

Bias

Essential Question: How can we make engines more efficient?

Independent Work: Develop your own hypothesis based

on the essential question. Please use (if..then..because…)

Essential Question: How can we make engines more efficient?

Group Work- page 7As a group, write down a hypothesis

and a null hypothesis that you all agree with based on the essential question. Please use (if..then..because…)

Independent Work- Key Words (use your notes)

Define the following: Experiment

Observe Qualitative data

Quantitative data

Students Will Be Able To (SWBAT): Understand why it is important to have

accuracy, honesty, quality and care when collecting data.

Collect data and record data to answer the following essential question: “How much effort mass is required to move various resistance masses?”

Use mathematical skills to find the average effort mass.

Essential Question: How much effort mass is required to move various resistance masses?”

Journal Entry: Blended Science Booklet page 8

Data CollectionExplain in your own words why

accuracy, honesty, quality and care are important when collecting data.

Why accuracy, honesty, quality and care are important when collecting data?

When you perform the procedure you have to collect data with charts, graphs, and other math skills.

Collecting data helps you put together your conclusion.

Scientists use the metric system to measure their units.

Data is important because in order to duplicate an experiment they'd need the precise measurements

Why do we need 3 trials for all experiments?

Procedure page 9

Retrieve your blended science bin.

Set up your string and binder clip system. (refer back to pages 2 and

3)

Materials needed today…

3 Large binder clips 2 small paper clips Kite string 2 slotted mass ( two hooks with

weights) Lid from your blue bin

Journal EntryBased on the picture below, who or what would

represent the effort mass and who or what would represent the resistance mass. Why?

500lbs 200lbs

What we are testing today…Essential Question: How much effort mass is required to move various resistance masses?

Effort mass (mass used to move

a higher massed object)

Resistance mass (mass that is trying

to be moved)

500lbs 200lbs

Write down at least 3 questions that come up during the course of this

experiment.

Discussion Questions- Talk with your team and write your individual responses.

What is the difference between effort mass and resistance

masses?

How is it possible for a lower effort mass to move a higher resistance

mass?
