GRAVITY DROP CHALLENGE
ACTIVITY FOR GRAVITY
"In the 'Gravity Drop Challenge,' primary 4 pupils explore the fundamental concept of gravity through
hands-on experiments, measurements, and discussions, while integrating math and English skills, and
gaining historical context, creating an engaging cross-curricular learning experience."
Mark Lee & Abdul BaariSubject: Mathematics
Gravity Concept: Measuring the
height from which objects are
dropped and calculating time
intervals, reinforcing
mathematical skills.MEASUREMENT
(MATHEMATICS)DSKPSubject: Science (Physics)
Gravity Concept: Introduction to the concept of
gravity, explaining it as the force that pulls objects
toward the Earth's center.INTRODUCTION (CONTENT KNOWLEDGE)Procedure
Step 1: Introduction- Explain gravity as the force pulling
objects to Earth (Science). - Tell the history
Step 2: Hands-On Experiment- Group students and provide objects
of varying weights. - Challenge them to predict which
object falls fastest (Science).
Step 3: Measurement- Have students measure drop
heights and record times
(Mathematics).
Step 4: Writing- Instruct students to write brief
explanations of their findings
(English).
Step 5: Discussion- Lead a class discussion on gravity's
role in the results (Science).
0102Subject: History
Gravity Concept: Exploring the
historical context of our
understanding of gravity,
discussing key figures like Isaac
Newton and Galileo Galilei.HISTORICAL CONTEXT
(HISTORY)Small objects (e.g., marbles, balls,
feathers, paper clips)
Measuring tape or ruler
A timer
Whiteboard or chalkboard
A projector or visual aids (for the
TPACK component)Materials Needed:Subject : Science Year 4
Topic 9 : Earth
Subtopic : GravitySubject: Technology
Gravity Concept: Use of technology for visual aids
and historical context, showing animations and videos
to enhance understanding of gravity.
Using technology to show how gravity works
differently in space, connecting the activity to the
concept of microgravity.TPACK INTEGRATION (TECHNOLOGY):
