LDSB Green Energy Skills Challenge - Gr. 7/8 (Teams of 4)

When: February 29, 2024

Where: St. Lawrence College

Maximum Participants: 8

9:45am - 12:00pm        Competition

12:00pm - 12:30pm        Lunch

12:30pm - 1:30pm        Competition

1:30pm - 2:00pm          Awards

Purpose of the Contest:

To provide competitors with the opportunity to demonstrate practical and theoretical application

of their skills and knowledge in the industry relevant to:

● Construction properties: structure and strength

● Measuring and working with voltage

● Motors and generators

● Renewable energy sources

Teams of four Grade 7/8 students from the same school will design and construct a wind turbine. Due to material availability this challenge will be capped at 8 teams total, decided on a first-come-first-served basis. If schools are interested in sending more than one team, they are asked to host their own challenge to narrow the choice down to one team submission for the LDSB Skills Challenge. 

Participating teams will be given a full materials kit prior to the challenge date. Materials can be used at the discretion of each team, keeping in mind that efficient use is part of the criteria. Design thinking and planning will be needed. Each team must bring two copies of their design sketches and/or blueprints. Sketches and blueprints may be hand-drawn, a CAD design or other computer aided drawing. Drawings must be done by student team members.

At the challenge, teams will be given one hour to assemble their materials to construct their wind turbines. All materials must come to the challenge unassembled, but can be individually altered prior to challenge to aid with efficient assembly.

Allowed prefabrication prior to challenge [ONLY]:

- Individual wind turbine blades (unattached from rotor)

- DC motor mount (unattached from base/rotor)

Clothing & Safety Requirements During Challenge:

Competitors must supply and wear the appropriate clothing and protective gear::

• Safety eyewear (must include side shields).

• Long pants and appropriate shirt (long/short sleeves. No sleeveless or oversized shirts/hoodies)

• No inappropriate slogans or messages

• No necklaces or bracelets.

• No school identification should be worn.

• Closed toed shoes.

• No cell phones allowed in the competition area.

**Please note: Failure to wear personal protective equipment in an appropriate manner could result in deductions. More than one warning may result in competitor(s) being disqualified from the contest.

Size Requirements:

● The base of the wind turbine must be NO larger than 30 x 30 cm in width/length, and NO larger than 1 metre in height (from bottom of base to top of turbine blades).

● The diameter of the blades when attached to the rotor cannot exceed 80cm (From blade tip to opposite blade tip). Teams

can choose blade design / total amount of blades.

Pre-Challenge Materials & Expectations:

Material kits will be provided to each teacher/team prior to the challenge. No additional materials can be used on the wind turbine. Tools used to create the individual components out of the materials are at the discretion of each teacher/team. Only select tools will be available during assembly. Please remember that only the wind turbine blades and DC motor + mount can be prefabricated and brought to the challenge. All remaining materials should be organized and brought to the challenge independent and unassembled from each other. It is recommended that teams bring all remaining materials from the kit to the challenge in case they are needed. 

*Please make sure that the +/- terminals on the DC motor are accessible during the challenge..

Recommended Tools for Pre-Challenge:

- Mitre Box / Saw (available upon request from committee, if needed)

- Hot Glue Gun (small and/or large)

- Clamps

Challenge Materials & Expectations:

The majority of assembly (ie. base structure, turbine rotor with blades, and attaching DC motor + mount) should be planned to take place during the challenge. Teams are encouraged to create detailed blueprints and design sketches to aid in assembly.

Materials/Tools Accessible During Challenge (supplied by committee):

- Hot Glue Gun + 2 glue sticks (per team)

- Mitre Box and Saw

- Clamps

- Additional 2’ wood lengths (1.5 cm x 0.5 cm)

- Additional cardboard

- Scissors

- Corrugated Cardboard Cutter

- Ruler/Metre Stick/Tape Measure

- Protractor

- Pencils/markers/paper

Challenge Breakdown:

1) 1-hour Assembly: Teams will have 60 minutes to assemble their wind turbine based on pre-challenge planning. At this time,

teams will be evaluated on their transferable skills and design criteria. Teams should submit 1 copy of their design

sketches/blueprints at this time. Following the 60-minute assembly, teams will be expected to submit their wind turbine.

No more alterations will be allowed after the assembly period.

2) Performance: Each group will place their wind turbine on the testing platform (no clamps allowed) for a 2-minute duration

with wind generated by a portable fan placed ~1 metre from their turbine and pointed directly towards it. A voltage metre will be attached to the wind turbine DC motor and monitored for output. Teams will be evaluated additionally on the transferable skills, design and electrical output.

3) Questioning & Consolidation: Following team demonstrations, each group will be asked 1 mandatory question and 3

additional questions. Answers can be prepared ahead of time, but each competitor will be expected to answer (without

reading notes).

Criteria Explanation Points

Transferable Skills


Sharing of ideas and responsibilities. /5

Oral Communication: How clear and concise responses to questions were communicated. /5

Problem Solving: How well teams make decisions based on problems that arise during assembly. /5

Time Management: Effective use of time during assembly. /5

Critical and Creative Thinking:

Each team will answer a mandatory question and three additional questions that will be chosen at random. Each question must be answered by a different member of the team. Teams can select whom they wish to answer each question.

Mandatory Question: What are the components of a functioning wind turbine and how do these components aid in generating energy?

Additional Questions:

1. Which aspect of this challenge did you, specifically, feel you had the most impact with and why?

2. If you were to revisit this challenge, what would you do differently and why?

3. Why did you choose to participate in this challenge?

4. How do you think schools can encourage students to participate in challenges like this?

5. Do you see yourself in a career relating in any way to this challenge? Explain.

Provincial Event:

The team(s) that garner the most points following the challenge will have an opportunity to represent LDSB at the provincial level. More guidance and further understanding about qualifying for the provincial event will be communicated at a later date.
