Grade 4: Electric Circuits Unit
Overview
In this unit, students will discover that electricity in
circuits can generate energy in the form of light, heat, and magnetism.
Through a series of investigations, students will wire a simple electric
circuit, build and use a circuit tester, apply the information they have
discovered to build a flashlight and to design and wire a model cardboard
house. Students will also learn that knowledge of electricity has given
scientists new ways to explore other scientific topics - chemistry, physics,
biology, and medicine.
Building Successful Foundations in Science - Elementary science
integrates and organizes student scientific knowledge through a foundation
made up of 'Bricks" of Big Ideas put together with the "Mortar" of Unifying
Concepts. |

Enduring Understandings
- important ideas that students should carry with them years beyond the
instruction received this year.
- A common vocabulary is needed to communicate about the scientific
procedure.
- A hypothesis is a testable prediction as to the outcome of a
scientific investigation.
- A well designed investigation involves the use of a written plan
that identifies the materials to be used, the procedure to follow, and
the variables. A plan needs to be followed to make sure all steps in an
investigation are completed.
- A scientist uses many tools when conducting an investigation.
- Complete data makes it possible to explain the results of an
investigation and compare it with the prediction.
- When data is analyzed, the results can be communicated in a variety
of ways.
- Energy comes in many forms. It can be converted from one form to
another.
- Electricity is energy that flows through circuits to power devices. A home can be wired using series and parallel circuits.
- The larger the energy source, the greater the output. (e.g.
Conductors allow energy to move, while insulators inhibit the movement
of energy flow).
- Energy has a source and can be distributed by various mediums and
can undergo either a physical or chemical change. (e.g. Electrical
energy has a source, is carried by wires, and is converted into heat,
light, or motion).
- All forms of energy involve a system that is capable of transferring
or transforming energy.
- A written plan must be followed in the correct sequence to make sure
it is done in the same way each time.
- An investigation should be done more than once to make sure the data
is accurate.
- Many tools are available to help gather data. Compare and contrast date with other groups to make sure it is
accurate. Data can be visually represented with labeled diagrams, charts,
tables, or graphs
- Errors can be identified by repeating an investigation or comparing
results with other groups. Data can be graphically represented through bar graphs, line graphs,
pictographs, or pie charts. Data can be analyzed to predict further change. Models make it possible to represent events or objects.
- There are many safety rules to follow when doing an investigation to
keep yourself and others safe.
Essential Questions
- most important “big picture” questions students should be able to answer
after completing learning activities.
- What common vocabulary should be used when conducting an
investigation?
- Why are predictions an important part of the scientific process?
How can we make better predictions?
- Why should we follow a plan when conducting an investigation?
What tools are available to gather data when conducting an
investigation? How does data help us explain our investigation? What
are some of the ways we can collect data? How can we
communicate the results of our investigation to others?
- What are the different properties of electricity? What materials
carry electricity and which do not? How can we distinguish between a
parallel and series circuit? How can a home be wired for
electricity?
- How much energy input will be needed to obtain the desired
energy output? (e.g. What materials conduct electricity? What
materials are insulators? How will a plant grow to its desired
height?)
- How is an energy source (e.g. battery) converted into usable
energy (e.g. electricity)?
- What components are necessary in a system to transfer or
transform energy? (e.g. What is needed to make a complete circuit?)
- How can we make sure an investigation is done the same way each
time?
- How can we make sure our data is accurate? How can we visually
represent data? What tools are available to help gather data? How
can we identify errors in our data? How can data be graphically
represented?
- How does data help us make better predictions? How can
models help complete a scientific investigation?
- What are safety procedures to follow when completing an
investigation?

Frequency Standards Other
Standards & E-skills
Standard 1:
Students understand the processes of scientific investigations and
design, conduct, communicate about, and evaluate such investigation.
Standard 2: Physical Science: Students know and understand common
properties, forms, and changes in matter and energy. Students know that
matter has characteristic properties which are related to its composition
and structure. Students understand that energy appears in different forms
and can move (be transferred) and change (be transformed). Students
understand that interactions can produce changes in a system, although the
total quantities of matter and energy remain unchanged.
