Science: Grade 4
Unit: Electricity
Purposes: Static Electricity, Circuits, Conductors and Insulators
Essential Questions:


Description:
In this unit, students discover how electricity works through simple investigations.

Project Foldable All of the students' work is collected in this Top Pocket Foldable.


Desired Results
Established Goals:


CT Science Framework
Students will understand that electricity in circuits can be transformed into light, heat, sound and magnetic effects.

  1. Construct complete (closed) and incomplete (open) series circuits in which electrical energy is transformed into heat, motion and or sound, and light energy
  2. Draw labeled diagrams of complete and incomplete circuits and explain necessary components and how components must be arranged to make a complete circuit.
  3. Predict whether diagrammed circuit configurations will light a bulb
  4. Develop a method for testing conductivity and analyze data to generalize whichmaterials are good electrical conductors and which are good insulators
  5. Observe magnetic effects associated with electricity and investigate factors that affect the strength of an electromagnet.



Connecticut Mastery Test Objectives
Science
B14. Describe how batteries and wires can transfer energy to light a bulb.
B15. Explain how simple electrical circuits can be used to determine which materials conduct electricity.

Frontloading Activities
These introductory activities help connect to and build students' background knowledge.
Where does electricity come from? How is it used in everyday life? In this introductory activity, students respond to the essential question in small groups, tapping into their background knowledge.

KWHL Students complete a KWH (what I know about electricity, want to know, how I can find out) chart.



Learning About Electricity
Learning Activities
Materials
Lesson 1: Atoms Students learn that atoms are made of protons, neutrons, and electrons. First, they memorize the 3 parts of an atom through a Whole Brain teaching method called Teach-OK. Then, they make a human atom, acting out the parts. Students draw and label a diagram of an atom inside their Electricity Foldable.
Teach-OK
Pictures of Atom
Lesson 2: Introduction to Static Electricity
Students watch an introductory video about Static Electricity.
Discovery Education Video: Junior Electrician- Static Electricity
Static Electricity Pretest (comes with video)
Lesson 3: Static Electricity Lab
Students perform static electricity experiments.
Static Electricity Lab Sheets
Bill Nye Static Electricity
Performance Task: After reviewing static electricity and how it works through Brainpop and a DK Interactive, students write about their experiments.

Lesson 4: Current Electricity Lab: Light the Bulb
Students try to make the light bulb work using a piece of wire, a battery and a light bulb. After seeing how many ways they can make it work, record what worked and did not work on the board in a 2 column chart.

Discovery Education: The Magic Schoolbus Gets Charged
Lesson 5: Create a Switch First, students review complete and incomplete circuits with Blob's Guide to Electricity. Then, they make a 2 tab foldable, illustrating a circuit that works on one side and circuit that does not work on the other. Underneath the tab, they are to explain why. Then, introduce switches with Blobs Guide before doing the experiment. Fill out the lab sheet together (guided).

Lesson 6: Conductors and Insulators Students perform the experiment and then fill in the sheet together on the Smartboard. After that, they create a foldable, recording conductors on one side and insulators on the other.
