Food and diet

Calorie values

Junk food:

  • Costs versus home cooked equivalent.
  • Exploration of levels of fat, sodium, carbohydrates.
  • Packaging exploration.
  • Amount of waste product – packaging etc.
  • CensusAtSchool – Sugar guzzlers
  • Links with home economics, health and PE, science.

Food prices

  • Compare different foods to buy 100g, for example, different vegetables, different meats.
  • Compare same food, same amount across different shops.
  • Track food prices over a period of time, for example, the cost of different vegetables through the year, during their growing season and then off season.

Water

Designing a vegetable garden

  • Shape, size, amount of soil.
  • Cost of planting and growing vegetables vs store bought.

Possible achievement objectives

Select from below depending on the teaching and learning activities chosen.

  • NA6-1 Apply direct and inverse relationships with linear proportions.
  • NA6-4 Find optimal solutions, using numerical approaches.

Measurement

  • GM5-1Select and use appropriate metric units for length, area, volume and capacity, weight (mass), temperature, angle, and time, with awareness that measurements are approximate.
  • GM5-2 Convert between metric units, using decimals.

Statistical investigation

  • S5-1 Plan and conduct surveys and experiments using the statistical enquiry cycle:
    • A - determining appropriate variables and measures
    • B - considering sources of variation
    • C - gathering and cleaning data
    • D - using multiple displays
    • E - comparing sample distributions visually
    • F - presenting a report of findings.
  • S6-1 Plan and conduct investigations using the statistical enquiry cycle:
    • A - justifying the variables and measures used
    • C - identifying and communicating features in context using multiple displays
    • E - justifying findings, using displays and measures.

Exercise

  • Data collection related to exercise:
    • What type of exercise?
    • Heart rate for different exercises.
    • Frequency and time of exercise
    • Group/team/individual
    • Hours per day
    • Hours per week
  • Aerobic vs anaerobic
  • Body mass index
