Notes for teachers

List of Materials:

• Prerequisite knowledge: Ohm’s Law, Series and Parallel Circuits.
• Context: This lesson can be completed in 3 hour period class (3days)
• Groupings: Students can work in small groups of 2-3.
• Targeted Output: Building design (circuit diagram) must be approved before identifying the materials and building the Wikiup.
• Expectations: Wikiup with working circuits
• Constraints. Use the Order form for students to decide materials when building their wikiup.

Arizona Science Standards

Science Standards:

​

Plus HS+Phy.P4U1.8

USE mathematics and computational thinking to EXPLAIN the relationships between power, current, voltage, and resistance.

​

• ​
• ​

MS-ETS1 Engineering Design

MS-ETS1-1

DEFINE the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.

​

​

Engineering (NGSS)

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)

• Revisit the Phet Building Plan (Circuit Diagram)
• Identify the project constraints and order materials using limited funds
• Part II. Wikiup Building and Building Inspection
• Part II Wikiup Design and Design Evaluation

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?

​

Traditional Ecological Knowledge (TEK) to learn about Wikiup

Part I. Building Plan (Circuit Diagram) using Phet simulations

Hands-on Activity Instructions

Part II, In group of 2-3, students will build their wikiup with:

• Series and Parallel circuits working independently
• There is a switch in each room
• One room has 2 lights wired correctly
• One room has 3 lights in parallel wired correctly
• One outside light works independently and is wired correctly.
• The house is at least 4” x 6 “ x 1” (close to the size of a shoebox)

Hands-on Activity Instructions

Part III, In group of 2-3, students will use their creativity to design their wikiup:

• Rooms must be decorated with furniture
• Use native plants like Yucca (Igaye), Mesquite tree (Iyah), Willow tree (K’ailtsoge), Beargrass (Bį’), and other plants that are used to build wikiups.

Assessment

Assessment

Differentiation

Tier 2 and 3

• 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

• Help in troubleshooting and assisting Tier 2 and 3 students with their series and parallel connections.
• Use a multimeter to measure the voltage and current of their circuit and compare it with the Phet simulations reading.
• Discuss the relationships between the amount of current and voltage in the series and parallel connections.
