Objective
By the end of this lesson, you will be able to apply mathematical concepts, understand the physics behind ice skating, and explore the science of ice and its effects on movement.
Materials and Prep
- Ice skating rink or a frozen pond
- Ice skates
- Warm clothing
- Pen and paper for note-taking
- Water bottle
Prior knowledge of basic math operations, such as addition, subtraction, multiplication, and division, is helpful.
Activities
- Measure Your Stride: Take a few steps on the ice and measure the distance covered by each stride. Calculate the average stride length.
- Timing the Glide: Time how long it takes for you to glide across a specific distance on the ice. Repeat the activity multiple times and calculate the average time.
- Weight Distribution: Experiment with shifting your weight from one foot to another while gliding. Observe how it affects your balance and speed.
- Ice Thickness and Pressure: Measure the thickness of the ice at different spots on the rink or pond. Discuss how the thickness of the ice affects the pressure exerted by your skates.
- Ice Friction: Observe the differences in gliding on smooth ice versus rough ice. Discuss the concept of friction and how it impacts your movement.
Talking Points
- Stride Measurement: "Let's measure how far we can go with each stride on the ice. We can calculate the average stride length by adding up the distances and dividing by the number of strides."
- Glide Timing: "Timing how long it takes for us to glide across a specific distance can help us understand our speed. We can find the average time by adding up the times and dividing by the number of trials."
- Weight Distribution: "Shifting our weight from one foot to another affects our balance and speed while gliding. Let's experiment with weight distribution and observe the changes."
- Ice Thickness and Pressure: "The thickness of the ice affects the pressure exerted by our skates. We can measure the ice thickness at different spots and discuss how it impacts our skating experience."
- Ice Friction: "Smooth ice allows us to glide more easily, while rough ice creates more friction. Let's observe and discuss how different ice surfaces affect our movement."
