into a law.

Skills to be developed:
Experimental: Use research skills on the Internet to find specific information

and Newton

Technology component: The experimental group will use the Internet to conduct web
quests on Galileo and Newton. They will also use Power Point to create
presentations, working as a class, on the lives of both men.

ii. Use reference materials to locate information needed for
research sheet.

iv. Each group will create a poster depicting Galileo or Newton.
v. Groups will present their posters to the class.
3. Example-Students will gather information through research techniques.
Students will use the Internet as data resource. Students will use textbook,
encyclopedias, reference books and other printed materials as data resource.

Research questions:
1. When was Galileo born?
2. Where was Galileo born?
3. Name one discovery that Galileo made.
4. What time period did Galileo live in?
5. What was Galileo’s theory regarding inertia?
6. When was Newton born?
7. Where was Newton born?
8. Name one discovery that Newton made?
9. What was Newton’s Law of Inertia?
10. What is inertia?

Discuss with students why time period and birth place would be important.
Different technology, different sources, who came first, etc.
Evaluation:
Students will be observed during research activity.
Students will be observed presentation.
Students will turn in web quests and research sheets.
Students will be given a written test.
Newton’s First Law

Day 5

Lesson Goal: Demonstrate Newton’s First Law

Concept to be developed:
1. Newton’s First Law: An object moving at a constant velocity keeps moving at
that velocity unless a net force acts on it. If an object is at rest, it stays at rest
unless a net force acts on it.

Skills to be developed:
1. Critical thinking
2. Discussion

Objectives:
1. Students will use Newton’s first law to explain the motion of an object.

Materials:
Tub or similar container
Water

Safety: Water may spill. Wear protective apron and watch footing in wet areas.

Technology component: Technology does not play into this activity. It is done to
provide background knowledge needed for further activities.

Procedure:
1. Foundation – Introduction to Newton’s first law
a. Read section in text on Newton’s first law
b. Review the terms velocity and acceleration

2. Concept Development – First law of motion activity
a. Divide students into groups of four
b. Give each group a tub filled ¾ full with water
c. Measure the depth of the water
d. Two students from each group stand at the beginning of a
predetermined course, while the other two students stand at the end
(Make sure the course has some turns in it.)
e. When told to begin, the first student carries the tub of water to one of
the students at the end.
f. Upon reaching the end, the first student trades off the tub to the second
student who walks back to the beginning.
g. Back at the beginning, the second student hands off the tub to the third
student who walks to the end.
h. At the end, the third student trades off the tub to the fourth student
who walks back to the beginning.
i. After the fourth student crosses the beginning line, students measure
the water in their tubs again.
j. Students discuss what happened to the water in the tub. (Why is there
less water than at the beginning?)
k. Students work in their group to come up with an answer to the
following question: How does this activity demonstrate Newton’s first
law of motion?
l. As a group, write an answer to the question above.

Evaluation:
Students will be observed throughout the activity.
Students will be observed while discussing the question within their group.
(Listening for discussion skills)
Students will turn in their group’s written answer to the question in step L.
Students will be given a written test.
