Machines
Edheads (4-7)
Students explore different rooms and must identify the simple
machines.
Edheads, Compound Machines (4-7)
Students follow a compound machine, examine all its parts, and
examine forces, gravity, and friction.
Design and Test Site,
Pearson Prentice Hall
This
interactive 3D simulation allows students to work on the
development of a piece of virtual machinery, capable of
launching giant paintballs. Using the Design and Test
methodology, students must create their hurling machine so that
it is capable of hitting the multiple targets within the virtual
world. In order to hit all of the targets students must design
their device so it is capable of launching for distance, height,
and strength. Students are given a budget that they must
complete the project within, each shot at the target will cost
the student part of their budget, so the fewer shots required
the better the student does. Launchers must be designed for the
assigned task, tested, modified, tested again, and repeated
until the student has hit each target. Students are able to
customize the arm length, spring strength, ball weight, angle of
release, and tension in order to hit each target.
