Module 2: How to Use the Scientific Calculator and Conversion of SI Units

Hi girls! Welcome to Module 2.
Here, we are going to learn the exciting preliminary concepts that
are important in understanding the different lessons for the three
terms this school year.
These are:

How to Use the Scientific Calculator
Conversion of SI Units

Goals of the Subject: To deliberately develop in the students the capacity to do scientific

thinking, critical thinking, and problem-solving real life situations.

At the end of this module, you will be able to:
1. Know how to use the scientific calculator for the purpose of pre-requisite skill in
solving word problems later on.
2. Convert measurements from one unit to another.

Essential Questions
1. How do we maximize the use of scientific calculator in learning science concepts?
2. How can you apply conversion of measurements in your daily activities?

Lesson 1: Use of Scientific Calculator

Look at these .
Do you know what are
these called and what
are these for?

Yes, you are right, these are scientific calculators or commonly called as sci cal.
We will need one of these in some topics this school year!

A sci cal is a type of electronic calculator Make sure to have your own

So far so good? Are the explanations on the use of sci cal clear,

so far? If not, feel free to email me so we can schedule our
one-on-one conversation. Keep on exploring your sci cal for the
mean time.

in a 25 kilogram sack of rice?

answers. Discuss it with them.

What took place in the ‘rice scenario’ is an example of
conversion of SI units.

KEY CONCEPT 2

Conversion is a multi-step The SI Base Units
process that involves
multiplication or division by a
numerical factor.

The SI is constructed from

seven base units, which are

adequate to describe most of

the measurements used in

science, industry and

commerce.

Lesson 2: Conversion of SI Units

KEY CONCEPT 3

Units belonging to the International System of Units (SI), as interpreted or
modified for use in the United States by the Secretary of Commerce
through the National Institute of Standards and Technology may be used
in:

● trade and commerce, SI Units
● procurements, are used in
● grants and other business-related activities,
● in educational information, and, studying
● as guidance in publications science.

to increase understanding of the metric system.

All the SI units and standards are agreed upon and understood by scientists all over the
world.

To find out how many grams are there in a 25kg sack of rice, study how did we convert
from one unit to another and reach the answer.

solution:

Given Conversion Factor We are looking for How do we get it
25kg
1kg = 1000g ?______ g This method is called Dimensional
answer: Analysis
kilogram (kg)
gram (g) You can use your sci cal to compute for
this.

25kg = 25,000g

explanation:

This means that, to convert from 25 kilograms to grams, multiply 25
kilograms by 1000 grams. Then, the answer is 25,000 grams.
This means that for every 25 kilograms of a sack of rice we buy, the
equivalent value in grams is 25,000 grams.

How was it? Still alive? Stay positive if you are
still having a hard time. It’s natural to feel that
way. I, too, had a hard time before, but I kept on
practicing until finally I got it right. There is
hope, girls.

Lessons 1 and 2

MA 2 15 Points

Interview three adults you know (you can email, chat

or call them).

Ask them the advantage/s if one knows how to

convert a particular unit of measurement to another.

Write or record their responses first in your

notebook. Ask them to mention clear specific

scenarios or personal experiences to explain their

answers further.

Rubric
5 points each for every clear response or answer from the interviewee.
This means that each adult was able to give one real life application
of conversion of units. Please make sure also that there are no
repetition of answers. The more varied, the better.

Format
This will be placed in your Grade 7 Science Interactive Notebook.

No template for this. Just provide the information this task is
requiring you.

1. Identifiers of the interviewee
● Name (optional)
● Age
● Profession or what the person does in life

2. Answers of the interviewee

Before ending this Module 2, let’s clap and tell ourselves, Good
Job for all the effort and hard work! Thank you for trying
your best!

Now, let’s recall what we went through for the past weeks
learning everything here. Write your reflections, realizations,
suggestions, memes, jokes, topics which are your favorite or
you had a hard time learning on, or anything you wish to
release. Talk about it. You may doodle also using your favorite
pen.

I will take time to read this page because this is history, the
first two Modules in science 7 we had for the remote learning.
