Eighth Grade:

Unit 1 - Introduction to Physical Science

Section 3 - Measurement

Standard 9 - Investigation and Experimentation

Key Concepts:

Tools are used to make accurate measurements while collecting data.

The International System of Units (SI) is a system of measurement used by most scientists.

Assignments/Activities for Today:

-Using the International System of Units, measure your height.

-Then go outside to measure and record the shadows of four different objects.

**It is important that you measure and record the length of your shadow immediately

after measuring an objects shadow.

-Using a basic formula, we will determine the height of your objects based on the

measurements we recorded.
