1. Topic-
|
| Force of Gravity vs. Force of Air Pressure |
| |
|
2. Content-
|
| With this experiment, we can see that if by applying the upward
force of atmospheric pressure, we can even overcome the force of gravity. |
| |
|
3. Goals: Aims/Outcomes-
|
1. Tech about the 2 forces that we all have to deal with - Gravity
and air pressure.
2. Relate the everyday pressures that kids have and get them to think
how they can overcome them.
3. Relate how GRATITUDE even in the smallest amount is a force that
can overcome even the strongest of opponents. |
| |
|
|
4. Objectives-
|
1. Have kids understand the concept of FORCE
2. Learn the concept that forces are all around us and that even if
we aren't aware of them, they are still acting on us
3. Show how even with a little air pressure we can over come the biggest
force - gravity. |

A. Introduction-
1. This week in Science class we are going to have FUN! And in order
to have the most fun, I need everyone to pay attention at all times.
Be kind to each other and be respectful to everyone. We are going
to learn a lot this week about FORCE. What is force? Are the positive
or negative? Examples of some forces we can see and some we can't
see. And we are going to learn how we can exhibit Force on the people
and things around us.
2. What is Force? F=MA and explain. Force is the size and weight or
and object times how fast that object is accelerating. (give examples
of common objects applying force on each other. lean on a tree. explain
that the tree is applying force on the person and the person is applying
force on the tree. Why isn't the tree moving the person and why isn't
the person moving the tree?) Talk about the amount of force required
to throw a baseball, vs. a bowling ball.
3. Talk about the biggest force we know around us - GRAVITY. How God
setup gravity to keep us from floating away. But not so much gravity
that we would be crushed into the ground. |

B. Development-
1. So if gravity is the biggest force around, how does it help us?
2. How does Gravity slow us down?
3. How can we apply force of our own to overcome gravity? |
| |
|
|
C. Practice-
1. Have the kids jump! Jumping to see who can jump the highest...
relate that to how our muscles overcome gravity.
2. turn a cup of water over... watch how gravity "pulls" the water
out of the cup and on the ground. relate how the water represents
us. We think that we are OK in our little glasses.... but the world
can pull on us and make us fall to the ground. But how can we stand
up the the force of gravity and the "pressures" of what the world
and our friends tell us to do? We need Jesus. (the cardboard represents
Jesus and how he can keep us from falling)
3. Now, setup the trick with the cardboard. |

|
|
D. Independent Practice-
| Have the kids perform the experiment. Start with the right amount
of water and experiment with more or less to see how it effects the
results |
| |
|
|
E. Accommodations (Differentiated Instruction)-
|
|
F. Checking for understanding-
1. Did you see how if we make Jesus big enough that he can overcome
anything? even Gravity?
2. Jesus teaches us that our gratitude toward others can help him
be that force that can change even. |
| |
|
|
G. Closure-
1. What are some examples of how our gratitude can be that force
that can change our world around us?
2. How can we partner with Jesus to be a force for good? |
| |
|
7. Evaluation-
|
1. how many kids successfully kept the water in the glass?
2. how many kids participated in the discussion on how we can use
the force of gratitude? |
| |
|
8. Teacher Reflection-
|
| With limited time to run this, this introductory lesson is about
setting up the rest of the week. It's about setting the ground work
for understanding about the forces around us. |
