Electricity

**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.

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.

 * 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]

 * **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). || Electricity Vocabulary Foldable
 * **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. || Conductors and Insulators Foldable
