Description of Field Trip
This field trip is designed for students
to take either with their teacher or on
their own. The students will go to the
museum and investigate all of the
exhibits, which can be done in two to
three hours. During the visit, students
will have with them their study guide
sheet, which asks questions from most
of the exhibits. After observing and
interacting with the exhibit, they will
answer the questions provided on the
study guide. In some cases, the
answers to the questions from the
study guide at the exhibit will be seen

or described. Otherwise, the answers
can be taken with them in a sealed
envelope, which can be opened at the
conclusion of the trip.
Alternatively, the questions in the
study guide are designed so that they
can be answered before going to the
museum and then as they interact with
the exhibits, they can check the
answers they have already selected.

objects. As a basis for understanding this concept,

Conservation of Energy and
principles demonstrated by the
exhibits.
Momentum
2. The laws of conservation of energy and
momentum provide a way to predict and describe
the movement of objects. As a basis for
understanding this concept, students know:
How to solve problems involving elastic and
inelastic collisions in one dimension using the
principles of conservation of momentum and
energy
Waves
4. Waves have characteristic properties that do
not depend on the type of wave. As a basis for
understanding this concept, students know:
Waves carry energy from one place to another
How to identify transverse and longitudinal
waves in mechanical media such as springs,
ropes, and the Earth (seismic waves)
Sound is a longitudinal wave whose speed
depends on the properties of the medium in
which it propagates.

How Does a Solar Cell Work?
Bed of Nails
The principle of pressure explains how this works. Because the weight of the person is spread out over a large area the
force created by any one nail is not very much and therefore the pressure created by the nails is also small. Start removing
the nails one by one and the force and pressure will gradually increase. Pressure = Force/Area
or
Pressure =
Force/
Area
