Science Project “Heat and Smell” Complete School Projects on Air, Water, Weather and Temperature for Class 8, 9, 10 and 12 Students.
Heat and Smell
Materials Required:
- A pet cat or dog
- Pet food
- Three feeding bowls
- Plastic food wrap
- A sunny window
- Refrigerator
People prefer to eat food at varying temperatures. We eat cold ice cream, room-temperature peanut butter, jelly sandwiches and hot hamburgers.
Pet cats and dogs usually eat their food at room temperature. Will they eat their food, if it is cold? Will they eat it, if it is hot?
Do they prefer their food, heated or otherwise? What do you think your pet will like?
Put a small amount of pet food in three bowls. Cover each bowl with plastic food wrap. Place one bowl of food near a window, through which sun rays peeps into the room. Put another one into the refrigerator.
Put the third bowl on a table that is out of direct sunlight. After about an hour, take the plastic wrap off the bowls and put all three down, where your pet usually goes for food. Watch your pet. What is its reaction to the three bowls? From which bowl does your pet eat? Does it eat from more than one bowl?
You must find out if heat produces a stronger food smell. If so, maybe it is this strong smell from the warm food that attracts your pet, rather than the temperature of it. See if you can find out, if it’s true.
Also find out if cats and dogs react in the same way to foods of different temperatures.
