Acceptance of a New Concept

• A widely accepted way to explain how learners
  adopt new understandings of phenomena is
  presented in the Conceptual Change Model (CCM).
• There are two major components to the Conceptual
  Change Model.
• The first component are the conditions that need
  to be met in order for a person to adopt a new
  understanding. There are three conditions leading
  to the adoption of a new concept. A learner has
  to
• (1) become
  dissatisfied with their existing conception,
• (2) find the new
  conception intelligible,
• (3) find the new
  conception plausible and fruitful.
• The second component of the CCM is described as
  the status of the new conception. A conception
  has status when it meets any of the
  aforementioned conditions however, the more
  conditions that the new conception meets, the
  higher the status the new conception obtains, and
  hence, a higher probability of being adopted.

NSTA Board Adopts New Position Statement on
Laboratory Science
The NSTA Board of Directors has adopted a new
position statement which reaffirms the central
role laboratory investigations play in quality
science instruction. for science to be taught
properly and effectively, labs must be an
integral part of the science curriculum. The new
statement replaces Laboratory Science, which was
adopted in 1990.

The Power Supply
The power supply can be any 6-volt DC source.
This could be 4 AA batteries, a lantern battery
or a transformer. We are using a battery pack
obtained from a Polaroid film pack.

Qualitative Characteristics of Electricity
1. Connect the battery and observe the lights.
(number lit and brightness) 2. Describe the
effect of moving bulb unit 1 just enough to
break the circuit of the rest of the
bulbs. 3. Describe the effect of moving bulb
unit 2 just enough to break the circuit of
the rest of the bulbs.

Quantative Characteristics of Electricity
1. Volts - Pressure that cause the current to
flow. The potential difference across a conductor
in an electric field
2. Amperes - Rate of the current flow. One
ampere is approximately equivalent to
6.241509481018 electrons moving past a
boundary in one second.

1. Ohms - Resistance of the conductor (wire or
   hose) to the flow. A device has a resistance of
   one ohm if one volt causes a current of one
   ampere to flow.

4. Watts - Power produced due to the pressure
and the flow of the electrons.

Remember in series circuits amperage is constant
and in parallel circuits it is additive.
Therefore if we add the amperage for the series
circuit to the amperage for the parallel circuit
we should get the amperage for the entire
circuit. (0.16 0.27 0.43)
