Implementing Linked Lists
Students will implement singly and doubly linked lists, understanding node manipulation and traversal.
Key Questions
- Design the structure of a node for a linked list.
- Analyze the time complexity of insertion and deletion operations in a linked list.
- Construct a program that performs basic operations (add, delete, search) on a linked list.
Ontario Curriculum Expectations
About This Topic
The Law of Conservation of Energy is one of the most powerful principles in science. It states that in an isolated system, energy cannot be created or destroyed, only transformed. In Grade 11 Physics, students focus on the exchange between gravitational potential energy and kinetic energy, while also accounting for 'lost' energy due to friction and heat.
This topic is central to the Ontario curriculum's 'Energy and Society' strand. It allows students to analyze the efficiency of hydroelectric dams like those at Niagara Falls or the mechanics of a roller coaster at Canada’s Wonderland. Students grasp this concept faster through structured investigations where they track energy transformations in real time using ramps, pendulums, and digital sensors.
Active Learning Ideas
Inquiry Circle: The Pendulum Predictor
Students release a pendulum from a measured height and calculate its theoretical maximum speed at the bottom using energy conservation. They then use a photogate to measure the actual speed and calculate the percentage of energy 'lost' to air resistance and friction.
Simulation Game: Roller Coaster Designer
Using an online simulator, students must design a coaster that completes a loop without falling off. They must use the conservation of energy to justify the height of the first hill relative to the loop's diameter, explaining the energy transformations at each point.
Gallery Walk: Energy Transformations in Canada
Post images of various Canadian energy systems (a wind turbine in Ontario, a hydro dam in Quebec, a wood stove in the North). Students move in groups to identify the initial energy source and the sequence of transformations leading to the final useful energy form.
Watch Out for These Misconceptions
Common MisconceptionEnergy is 'used up' or 'disappears' when a machine stops.
What to Teach Instead
Energy is never lost; it just transforms into less useful forms like heat or sound. Hands-on experiments where students feel the warmth of a brake pad after stopping a spinning wheel provide immediate physical evidence of this transformation.
Common MisconceptionPotential energy is only present when an object is high up.
What to Teach Instead
Potential energy exists in many forms (elastic, chemical, magnetic). While Grade 11 focuses on gravitational potential, using 'bungee' simulations with rubber bands helps students see that energy can be stored in the stretching of materials as well.
