Go over the material with the students under the Science Concept and
Teacher Text. Answer any questions that the students may have about this
material.
|
|
Go over the safety rules for this activity. Students need to be
cautious when throwing the bricks, making sure that other students are a
safe distance away.
A suggestion to keep hands safe - garden gloves should be worn when
tossing the brick.
|
|
Go over the measuring rules for this activity. There should be
premeasured sights where the students can aim the brick: 5 feet, 7
feet, and 10 - 15 feet depending upon the strength of the students. The
scales will be used to weigh the bricks in figuring out the mathematical
formula of the amount of force that is needed to throw the brick.
(Remember that Force = Mass x Acceleration.
|
|
Proceed to the playing field where the brick will be tossed. Have
the students divide into groups of three. Have each group have a brick,
measuring tape, and one pair of garden gloves.
|
|
Have the team pre-measure distances for their toss and mark with a
stone.
|
|
|
|
Have each team member weigh their brick that they will toss. Have
them record how much the brick weighs on a piece of paper.
|
|
Have each team member take a turn throwing the brick 3 times and 3
different distances.
|
|
Have the other team members take down the distances that their team
members toss the brick.
|
|
Return to the classroom with the data that was gathered by the
different team members and figure out the force that was needed to toss
the brick. Remember the formula: Force = Mass x Acceleration. The
acceleration can be measured by how many seconds it takes the brick to go
from the point of toss to the point of landing. This can be approximated
by counting the seconds like: one, one thousand and one, one thousand
and two, one thousand and three, etc. Each one, one thousand and one,
etc. measures one second.

Compare results with one another in the class.
