Make a simple circut:
- The light-bulb lit bright!
- Both light-bulbs lit, but not very bright.
- When we unscrewed one lightbulb, the other light bulb did not remain lit.
- Both light bulbs lit bright!
- When we unscrewed one light bulb, the other light remained lit.
Note: We related it to how sometimes a Christmas light will go out on a string and all the other ones after it go out. And other times when one Christmas light goes out, only that one goes out. In this situation we prefer parallel circuits as opposed to series circuit.
Student-Centered activity: "Explore Independently":
- Materials: 1 battery, 1 bulb, 1 wire
- Start "See if you can light the bulb using only these materials. Show all the ways you tried:
It didn't work!
It worked!
2. After you've managed to light the bulb, "can you light it in a different way?"
It worked!
3.
- Can you light the bulb using 2 pieces of wire? Yes!
- Can you do it without the bulb touching the battery? Yes!
- Where must you touch the bulb to make it light? At the black bottom of the light bulb and at the side.
- How many places? 2.

Performances
|
• Content Standard: K-4
• Standard: Physical Science
• Content Standard B: Light, Heat, Electricity, and
Magnetism
• Benchmark: Electricity in circuits can produce light, heat, sound, and magnetic effects. Electrical circuits require a complete loop through which an electrical current can pass. |
A complete circuit is needed to
produce energy to light a light bulb.
|
Most students know that circuits require 2
wires to complete.
|
Students will be given many batteries, bulbs,
and wires and told to explore these materials. They will collect
evidence and show how they got their light bulb to light up in different
ways. They will then evaluate and communicate with other sources to justify
their findings.

5-E Criteria
|
Part(s) of the lesson that addresses this
inquiry criterion
|
More teacher-directed or
student-directed? Explain.
|
Engage
|
Students are given the following question, “How does a
light bulb work?” They will be handed flashlights, large light bulbs, small
light bulbs, night-lights, etc. to start exploring.
|
Teacher/student directed: “Learner engages in questions
provided by teacher, materials, or other source.” The students will be handed
materials to explore and also is given a question, but the learner will have
to opportunity to explore it.
|
Evidence
|
Students will be given a set of materials, such as
batteries, bulbs, and wires to figure out how to light the disconnected light
bulb.
|
Teacher/Student directed: “Learner directed to collect
certain data.” The teacher through the materials gives the students guidance,
but they are creating their own experimental trial and error session.
|
Explain
|
Students will take photos or draw diagrams out how they
lit their light bulb. They will explain in their notebooks of how a light
bulb got lit.
|
Student directed: “Learner explains own results.” The
learner is coming up with their evidence and recording their own data on how
a light bulb lights.
|
Evaluate
|
The students will briefly share their findings with their
classmates and discuss with one another where they can find additional
evidence to support their claims, such as books, internet, and even
contacting electricians or scientists.
|
Student directed: “Learners lead discussion and evaluation
of evidence.” The students are making connection between peers and through
other sources that they came up with.
|
Communicate
|
Once students fully understand the main principles of circuits,
they will present it to the whole class
|
Teacher/Student directed: “Learner forms reason as to why
this occurred based on the data they came up with using the materials and
outside sources.” The teacher can encourage complex student discussion and
offer more examples.

Reflection on pages 253-267:
This article showed how two teachers, Ms. Travis and Ms. Stone decided to use the science kit provided to them on the lesson of batteries, bulbs & wires. Ms. Stone conducted a more teacher-centered lesson while Ms. Travis allowed her students to be explorers of their own. Ms. Stone made an effort to have her students learn vocabulary in relation to the lab and encouraged her students to follow the lab step by step to ensure there were no 'mistakes' made. Ms. Travis began class with an essential question to find out the common misconceptions of her students. She guided her students in the exploration process by giving them potential steps. Though Ms. Travis's lesson was not completely an inquiry based lesson, I believe that it was still more effective because she was able to relate back topics to her students. The students seemed to be more engaged and ready to learn.
When I worked on this lab in class I can see how my probe was more like Ms. Travis's class. I was given an outline, but wasn't entirely sure what to do to make the lightbulb light with one wire. It was frusterating at times, but it's fun to realize the process you go through when you are discovering a new topic. It made me realize that I am not used to inquiry learning, but that it is still a great idea and something that I will want to push onto my students when I become a teacher. It will be a little scary allowing the students control but I think the payoff of them having "A-HA!" moments will be much greater.
