Microwave Ovens

What 3 molecules are microwaves attracted to?

• Fats, Sugar and Water
• Sugar, Water and Proteins
• Water, Proteins and Fats
• Fats, Proteins and Sugar

How do Electromagnetic Waves (Microwaves) cook food?

• The electromagnetic waves cause the molecules to become excited and vibrate. This causes friction between molecules which generates the heat to cook the food

• The electromagnetic waves heat up the food molecules in a similar way as a conventional oven

• The electromagnetic waves create a dry heat that warms the molecules in the food

• The electromagnetic waves send heat to the molecules which makes them begin to vibrate and cook

What are 3 microwave safe containers?

• Glass, Ceramic and Microwave Safe Plastic

• Foam plastic, Glass & Ceramic

• Glass, Plastic and Metal

• Ceramic, Glass and Metal

Which container is NOT safe for the microwave?

• Metal

• Microwave-safe plastics

• Glass

• Ceramic

Which container cooks more evenly and why?

• Shallow containers because the food is more spread out allowing the microwaves to reach more surface area of the food and not having to penetrate as deep

• Deep containers because it traps the microwaves in allowing more food to heat up.

Which shape containers cook more evenly and why?

• Round containers because there are no corners for the microwaves to overcook the food.

• Square containers because the foods in the corners tend to get overcooked due to small volume of food compared to large amount of microwave action.

What is true about the amount of food you place in the microwave?

• Does affect the cooking time
• Does not affect cooking time

What 3 movements/actions help improve even cooking of food?

• Stirring, Rotating and Covering

• Plastic, Glass and Ceramic

• Stirring, Resting and Shaking

Why don't microwaves brown or crisp foods like conventional ovens?

• They do not have a dry heat source
• They cook too fast to do this
• They can because they are the same as conventional ovens
• The cook too slow to do this

Why should you poke holes in baked potatoes when cooking in the microwave?

• To allow the steam from the water molecules to escape without bursting the skin
• To help them cook more evenly
• To allow the heat to get into the potato through the holes
• To allow insects to escape so you don't eat them
