1. Topic


2. Content

Gravity, Weight, Air Resistance and Mass 


3. Goals: Aims/Outcomes

1. Students will understand how gravity affects our life on Earth.
2. Students will be introduced to some basic concepts of physics.
3. Students will understand that there are many forces that affect
the speed in which things fall. 


4. Objectives

1. Students will be gather data and analyze it to make predictions.
2. Students will be able to identify forces that affect the speed
in which things fall.
3. Students will be able to explain that gravity makes everything
fall at the same speed. 


5. Materials and Aids

Light objects that include an empty soda can, a plastic fork, and
a piece of paper. Heavy objects will include a full soda can, a metal
fork, and a heavy book. Cameras will be used to record the droppings.
In addition, a projector and screen will be used to view the recorded
videos. 


6. Procedures/Methods

A. Introduction
1. Show a video of an astronaut walking on the moon. Discuss with
the class about gravity, mass, and weight. Talk about how the mass
of the moon and the Earth is different. On Earth, unlike the moon,
what goes up must come down. But what makes certain objects come down
faster than others?
2. Complete a KWL Chart on what students know and will learn about
gravity, mass, and weight.
3. Explain to students they will be performing a Drop Test Activity,
where they will be dropping different objects to see which one falls
faster. Ask students whether they think mass/weight will affect the
speed? Tell students to think of a feather and a rock before allowing
students to touch objects. Students will weigh the objects using the
classroom scale. 


B. Development
1. Students will form groups and complete a predictions worksheet.
They will list the items they think will drop from fastest to slowest.
2. Students will discuss with the entire class of their predictions.
The predictions will be written on the board and will be used to compared
with the actual results.
3. Students will go outside to perform the Drop Test Activity. 


C. Practice
1. Upon returning to the classroom, students will discuss the actual
results of the activity.
2. Students will write journal reflections.
3. Students will rewatch the drop test activity using the projector
and complete a graphic organizer to explain why certain objects dropped
faster than other objects. 


D. Independent Practice
1. Predictions Worksheet
2. Journal Reflections. Include Drawing.
3. KWL on Gravity, Mass, and Weight  Students will complete the "L"
section on their own. 


E. Accommodations (Differentiated Instruction)
1. Peer Teaching
2. Audiovisual Learning
3. Cooperative Learning 


F. Checking for understanding
1. Ticket Out the Door  Students should be able to answer, "What
did you learn today?" in regards to gravity, mass, air resistance,
or weight.
2. Journal Reflections with drawing.
3.General Observations. Predictions will be collected. Walk around
the room while students complete worksheets and journals. 


G. Closure
1. Mass does not affect the speed of falling objects.
2. Air resistance is the reason why lighter objects fall slower than
heavier objects. 


7. Evaluation

1. Students' journal reflections
2. Test scores 


8. Teacher Reflection

The lesson was a success. The students had a lot of fun going outside
to investigate which items would fall faster. It was a good idea to
have students measure the weight of the objects and compare them,
as the activity integrated science with math.
