Science Quiz 6th Grade

Becca noticed her soup was getting cold. Which of the following best explain how heat is transferred in this scenario?

• Cold from the soup is being transferred into the around the soup

• Cold from the air around the soup is being transferred into the soup.

• Heat from the air around the soup is being transferred into the soup.

• Heat from the soup is being transferred to the colder air around the soup

Which is true of light waves and sound waves?

• Light waves can travel through a vacuum, but sound waves need matter to transfer

• Sound waves can travel through a vacuum, but light waves cannot

• Neither can travel through the vacuum of outer space

• They can both travel through the vacuum of outer space

If you wanted to make a solar oven out of boxes, black paper, and aluminum foil, what would most likely be the job of the foil?

• Changing the visible light into infrared wave to cook the food.

• Absorbing the sunlight and changing it to heat to decrease cooking time.

• Reflecting the sunlight directing it to the food being cooked

• Transmitting heat from outside the cooker to inside the cooker.

If both of these beakers of water were placed in a sunny spot, which of the following would be true?

• The water in beaker Y will heat faster because the volume of water is greater

• The water in beaker X will heat faster because the volume of water is less

Tommy has a brown cup and a green cup. Each cup contains an equal amount of water. - The temperature of the water in the brown cup is 10°C. - The temperature of the water in the green cup is 30°C. Tommy places the brown cup next to the green cup so that the cups touch each other. How will heat flow between the cups?

• Heat will flow from the green cup to the brown cup, and the particles in the brown cup will speed up.

• Heat will flow from the brown cup to the green cup, and the particles in the brown cup will slowdown.

• Heat will flow from the green cup to the brown cup, and the particles in the brown cup will slow down.

• Heat will flow from the brown cup to the green cup, and the particles in the green cup will speed up.

Which statement best describes the relationship between the frequency and the wavelength of waves?

• As wavelength decreases, frequency remains the same.

• As wavelength changes, there is no change in frequency.

• As frequency increases, wavelength gets shorter.

• As frequency increases, wavelength gets longer.

An ice cube is placed in a pan and heated on a stove until it melts and then evaporates. Which best explains the change that occurred?

• The heat decreased the movement of the water molecules causing a change in state.

• The heat decreased the number of water molecules causing a change in state.

• The heat increased the number of water molecules causing a change in state.

• The heat increased the movement of the water molecules causing a change in state.
