and will not show during your presentation.)

• Lesson 13 Constructing a Flashlight
• Overview Building on the groundwork laid in
  Lesson 12, students incorporate the switch they
  have made into a flashlight they have designed.
  As students share the flashlights they have made,
  they also review series and parallel circuits.
• Objectives of the Lesson
• Students construct flashlights.
• Students discuss the similarities and
  differences between series and parallel circuits.
• Materials
• For each pair of students TWO storage boxes 1
  paper clip switch
• For every four students 4 sheets of 8 ½ x 11
  construction paper one pair of scissors one
  roll ¾ masking tape Crayons or markers

Think and Wonder
Flashlights come in many shapes and sizes, but
they have several things in common. You have
already listed the important parts of a
flashlight. What do you know about circuits that
might be useful in making a flashlight? -

1. Using the designs you made in Lesson 12, you are
   going to build a flashlight with your partner.
2. When we are all finished, we will present them
   to the entire class using PowerPoint so be sure
   to take several digital photos of your flashlight
   in progress. -

In your Laboratory Record Book

• Make a drawing AND a circuit diagram of your
  flashlight in your LRB.
• Take a digital photo of your flashlight and
  place it in your LRB.
• 4. If you finish before everyone else, use
  your colored pencils to decorate your
  flashlight. -

• Prepare a presentation for the class. You must
  include
• A description of the process of building your
  flashlight
• Any difficulties you had to overcome
• A demonstration of how the flashlight works
• A large version of the circuit diagram you used
  to build your flashlight
• Identify the type(s) of circuits you used -

As a way of helping students be organized and
give a professional presentation, you may want to
use this hyperlinked PowerPoint template. It
includes all the required elements plus it allows
students to be more creative. There is also a
rubric that can be used by the teacher and
audience for scoring.
