2nd Semester Science

A student is creating a model of the Earth and the Sun to explain why the length of day and night change throughout the year. What would be the most important feature to add to the model and why?

• The Earth should make a perfect circle around the Sun so the Sun’s light hits all surfaces equally.

• The Earth should make an elliptical orbit around the Sun so that the Sun is at different distances throughout the year.

• The Earth should be tilted on its axis as it goes around the Sun so that the amount of light hitting the Earth varies depending on the tilt.

• The Earth should be placed upright on its axis as it goes around the Sun so that it shows the Earth slowing its rotation.

Which argument regarding the earth’s tilt, the earth’s orbit, and the seasons on Earth is correct?

• The Earth’s orbit and the Earth’s tilt cause the seasons on Earth.

• The Earth’s orbit and the seasons on Earth cause the Earth’s tilt.

• The Earth’s tilt and the seasons on Earth cause the Earth’s orbit.

• The Earth’s tilt, the seasons on Earth, and the Earth’s orbit are not related.

• There are more daylight hours and there are less direct rays from the sun.

• There are more daylight hours and there are more direct rays from the sun.

• There are less daylight hours and there are less direct rays from the sun.

Which explanation is supported by this model?

• The Earth has the same exact hours of day and night. It is summer.

• The Northern Hemisphere has shorter days and longer nights. It is winter.

• The Northern Hemisphere has longer days and shorter nights. It is summer.

The model Earth during part of its orbit around the Sun.  Why don’t all parts of the Earth have day and night at the same time?

•  Earth revolves around the Sun on an axis, and it is day only.

• The Sun revolves around Earth, and it can only shine on half of Earth at one time.

• Earth rotates on its axis, and only the part of Earth facing the Sun experiences day.

• The moon revolves around Earth, and blocks the Sun from certain parts of Earth at different times.

What does the model below correctly show about the phases of the moon?

• It shows how each phase appears when viewed from earth

• It shows that the moon is actually always half illuminated in every phase

• It shows the reason that the moon is visible during the day and during the night

• It shows that the cycle of moon phases takes exactly one day

A student created the following chart to show the phases of the moon. What should the student do with the chart to correctly show the phases of the moon?

• Students should reorder the information by  starting at the full moon for the beginning of the month and ending at the new moon at the end of the month.

• Students should reorganize the information to show the phases in a circular flow chart to show that the patterns continue.

• Students should include the Sun as step 9 on the chart to show that the Sun has an impact on the phases of the moon.

• Students should reorganize the information to show the phases in chronological order from top to bottom.

A student is sitting at her desk one day, and notices that the lights in her classroom have a cover over them: She wonders if these covers affect the light in any way, and decides to plan an investigation to find out if they are transparent or translucent.  Which of the choices below is an investigation and will give her accurate results?

• She can do research on the internet to see if the company who builds the covers tells if they are transparent or translucent on their website.

• She can turn off the lights and try to see through the cover, deciding if the objects on the other side look clear or not.

• She can interview the workers who installed the ceiling, asking if they use transparent or translucent covers.

• She can take off one of the covers and shine a light through the cover, looking at the light carefully on both sides.
