Flashback Friday - MP3 Week 2

Scarlett, Daniel, and Benjamin are studying the rotation of the Earth. They want to know how long it takes for the Earth to complete one full rotation on its axis. Can you help them?

• 24 hours

• 36 hours

• 48 hours

• 12 hours

Henry, Ethan, and Isla are observing the day and night cycle. They are trying to understand the concept of day and night in relation to the Earth's rotation. Can you explain it to them?

• Day and night are caused by the Earth's distance from the Sun

• Day and night occur due to the Earth's tilt on its axis

• The concept of day and night is related to the Earth's rotation on its axis, causing different parts of the Earth to face the Sun at different times.

• Day and night are caused by the Moon's rotation around the Earth

William, Mia, and Ethan are planning a trip to space. They are curious to know how long it would take for their spaceship to complete one revolution around the Sun, assuming it follows the same path as Earth. Can you help them?

• 365.25 days

• 100 days

• 500 days

• 24 hours

Jackson, Avery, and Aria are studying about the Earth's movements. They are confused about the difference between rotation and revolution of the Earth. Can you help them understand?

• The rotation of the Earth causes the change of seasons, while the revolution of the Earth causes the Earth's tilt.

• The rotation of the Earth causes the change of seasons, while the revolution of the Earth causes day and night.

• The rotation of the Earth causes day and night, while the revolution of the Earth causes the change of seasons.

• Rotation and revolution of the Earth both cause day and night.

Name two elements from the periodic table and state their atomic number and atomic mass.

• Helium - Atomic number: 2, Atomic mass: 4.0026; Iron - Atomic number: 26, Atomic mass: 55.845

• Hydrogen - Atomic number: 1, Atomic mass: 1.008; Oxygen - Atomic number: 8, Atomic mass: 15.999

• Sodium - Atomic number: 11, Atomic mass: 22.990; Carbon - Atomic number: 6, Atomic mass: 12.011

• Gold - Atomic number: 79, Atomic mass: 196.967; Nitrogen - Atomic number: 7, Atomic mass: 14.007

Evelyn, Abigail, and Noah are studying the structure of an atom for their science project. They are discussing the roles of protons, neutrons, and electrons. Can you help them understand better?

• They should understand that protons, neutrons, and electrons are all located in the nucleus.

• They should understand that protons and electrons are located in the nucleus, while neutrons orbit around the nucleus.

• They should understand that protons and neutrons are located in the nucleus, while electrons orbit around the nucleus.

• They should understand that neutrons and electrons are located in the nucleus, while protons orbit around the nucleus.

Zoe, Daniel, and Olivia are studying the change in seasons on Earth. They are debating on what causes this change. Can you help them?

• Axial tilt and orbit around the sun

• The moon's phases

• Global warming

• The rotation of the Earth

Describe the relationship between the Earth's tilt and the occurrence of seasons.

• The occurrence of seasons is determined by the distance of the Earth from the Sun

• The Earth's tilt has no effect on the occurrence of seasons

• The Earth's tilt causes the same amount of sunlight to reach all parts of the Earth throughout the year

• The Earth's tilt causes different parts of the Earth to receive varying amounts of sunlight throughout the year, leading to the occurrence of seasons.

Abigail, Nora, and Aiden are participating in a science quiz. The quizmaster asks, 'What is the axial tilt of the Earth?' How should they answer?

• 23.5 degrees

• 45 degrees

• 90 degrees

• 0 degrees

Ava, Jackson, and Maya are studying the structure of an atom for their science project. They are particularly interested in understanding the role of electrons. Can you help them understand what electrons do in an atom?

• Electrons determine the mass of the atom

• Electrons orbit the nucleus and are involved in bonding and chemical reactions

• Electrons are located in the nucleus and have no role

• Electrons determine the size of the atom
