Educational Technology

​

Standard 4. Innovative Designer - Students USE a variety of technologies within a design process to IDENTIFY and SOLVE problems by creating new, useful or imaginative solutions

9-12.4.b. Students select and use digital tools to plan and manage a design process that considers design constraints and calculated risks.

​

Objective:

I will DESIGN and BUILD a functional model of my "WIKIUP dream house” with 2 bulbs in series, 3 bulbs in parallel, and 1 standalone bulb powered by a 9V battery.

​

Agenda (60 minutes)

• Community member or an Elder from the Community to present Wikiup, structure, significance, and native plants
• Review Series and Parallel circuits using Kahoot.it (https://create.kahoot.it/share/series-and-parallel-circuits/8922a5f9-49a2-4760-830d-72a7a3a29dcd)
• Create a circuit diagram using Phet simulations.
• Approval of design from the Teacher

Intro/Driving Question/Opening

​

​

What is a Wikiup?

What can disrupt the flow of electrons in a circuit?

​

What is the difference between light bulbs connected in series and parallel?

​

How are Currents affected by the increase/decrease of Voltage and Resistance?

​

Hands-on Activity Instructions

In group of 2-3:

• Use PhET simulations to build a schematic diagram (circuit diagram).
• The circuit diagram must clearly show one (1) room with two (2) lights in series, one (1) room with three (3) lights in parallel, and an independent outside light.
• All the rooms and light bulbs must be powered by a 9 Volts (v) battery.
• There must be a switch in each room.
• Get approval of the Building Plan ( circuit diagram)

Assessment

Differentiation

Tier 2 and 3

• Provide a schematic diagram (circuit diagram) that can serve as a guide for students when using the Phet Simulations
• Modify the number of rooms, instead of 3, Tier 2 students can create a circuit diagram of 2 rooms. While Tier 3 students can modify the # of rooms as well as the number of lightbulbs.

Remediation/Intervention

Extension/Enrichment

Tier 1

• Students who completed their circuit diagram before the allotted time, can work on using the Voltmeter and Ammeter to measure the amount of Voltage and Current, compare and contrast its value, and analyze its relationships.
• Students can also explore complex circuit and and discuss how it applies in their own home.
