### Example Question #1 : Reveal Patterns In Length And Direction Of Shadows

A series of photographs of a 1-meter stick and shadow were taken throughout the day. Students analyzed the photos and recorded the data in the table below. What pattern(s) are revealed about the length of the shadow in the provided data?

All of the answer choices are correct.

The length of the shadows increased after the peak.

The length of the shadow decreased throughout the day until it reached the Sun's peak.

The angle of the shadows decreased throughout the day.

All of the answer choices are correct.

### Example Question #2 : Reveal Patterns In Length And Direction Of Shadows

Mrs. Sweeterman's class is investigating shadows today in the science lab. She hands out a task card, a sheet of large white paper, a cup, and a flashlight to each group. They take turns holding the flashlight in various positions to observe the shadow made by the cup on paper. When all of the students finished their observations, the class discussed the shadows they made and how the amount of light impacted the size of the shadows. Their observations are documented below.

What caused the shadow to change during the investigation?

The cup changed when the size of the shadow changed.

The cup changed when the position of the shadow changed.

The shadow changed when the position of the cup changed.

The shadow changed when the position of the cup changed.

Explanation:

Data tables are a great way to organize and analyze information from an investigation or experiment. Analyzing data can often lead to patterns being recognized, and predictions about future measurements can be made. Based on the investigation that Mrs. Sweeterman's class conducted, it can be concluded that there is a relationship between the position of the cup and the position, length, and angle of the shadow. As the cup (Earth) moved positions, the shadow changed as well. The angle and length of the shadow also vary when the position of the cup (Earth) changes.

### Example Question #3 : Reveal Patterns In Length And Direction Of Shadows

A series of photographs of a 1-meter stick and shadow were taken throughout the day. Students analyzed the photos and recorded the data in the table below. What pattern(s) are revealed about the angle of the shadow in the provided data?

The measurement of angles increases as the day progresses.

The measurement of angles increases then decreases as the day progresses.

The measurement of angles remains the same as the day progresses.

The measurement of angles decreases as the day progresses.

The measurement of angles decreases as the day progresses.

Explanation:

Data tables are a great way to organize and analyze information from an investigation or experiment. In this investigation, a series of time-lapsed photos were taken from 6:00 am until 8:00 pm, and students measured the length of the shadow that a 1-meter long stick created as well as the angle of the shadow. When reviewing the data, a pattern was revealed about the angles of the shadow. The angle of the shadow decreased throughout the day until sunset when the shadow disappeared. Analyzing data can often lead to patterns being recognized, and predictions about future measurements can be made. A prediction could be made that a similar measurement of angles would be found tomorrow and each day thereafter.

### Example Question #4 : Reveal Patterns In Length And Direction Of Shadows

A series of photographs of a 1-meter stick and shadow were taken throughout the day. Students analyzed the photos and recorded the data in the table below. Based on this data, what can be predicted to happen with the shadows tomorrow if measured at the same time?

The measurements will be vastly less.

The measurements will be very similar.

The measurements will be vastly larger.

There is no way to predict what the measurements will be.

The measurements will be very similar.

Explanation:

### Example Question #5 : Reveal Patterns In Length And Direction Of Shadows

The orbits of Earth around the Sun and of the Moon around Earth, together with the rotation of Earth about an axis between its north and south poles, cause observable patterns. These include daily changes in the length and direction of shadows.

False

True

True

Explanation:

The statement in the question is correct. Patterns within shadows can be seen by measuring the length and direction and comparing them daily. The Earth's rotation causes the shadows to change throughout the day. The rotation of the Earth also causes day and night. The Earth's revolution causes slight changes in the length of these things because of its location in orbit.

### Example Question #6 : Reveal Patterns In Length And Direction Of Shadows

The NASA provided photo below is depicting what shadow pattern that happens nightly?

The Earth's rotation

The Moon phases

The Earth's revolution

The water cycle

The Moon phases

Explanation:

The shadow pattern that is depicted in the photo is the moon phases. The picture demonstrates where the Moon is located in regard to the Earth and how the Moon appears to us.

NASA explains more about this cycle, "If you have looked into the night sky, you may have noticed the Moon appears to change shape each night. Some nights, the Moon might look like a narrow crescent. Other nights, the Moon might look like a bright circle. And on other nights, you might not be able to see the Moon at all. The different shapes of the Moon that we see at different times of the month are called the Moon’s phases. The Moon does not produce its own light. There is only one source of light in our solar system, and that is the Sun. Without the Sun, our Moon would be completely dark. What you may have heard referred to as “moonlight” is actually just sunlight reflecting off of the Moon’s surface. The Sun’s light comes from one direction, and it always illuminates, or lights up, one half of the Moon – the side of the Moon that is facing the Sun. The other side of the Moon is dark."

### Example Question #7 : Reveal Patterns In Length And Direction Of Shadows

A moon phase is one of the shapes the moon seems to have as it orbits Earth. When Earth is between the moon and the sun, you see a Full Moon. When the moon is between Earth and the sun, you can’t see the moon at all.  What is this phase called?

New Moon

Third Quarter

First Quarter

Full Moon

New Moon

Explanation:

The shadow pattern that is depicted in the photo is the moon phases. The picture demonstrates where the Moon is located in regard to the Earth and how the Moon appears to us.

NASA explains more about this cycle, “If you have looked into the night sky, you may have noticed the Moon appears to change shape each night. Some nights, the Moon might look like a narrow crescent. Other nights, the Moon might look like a bright circle. And on other nights, you might not be able to see the Moon at all.

### Example Question #8 : Reveal Patterns In Length And Direction Of Shadows

If there was a full moon last night over Atlanta, Georgia, when would the next full moon occur over Atlanta?

Explanation:

The shadow pattern that is depicted in the photo is the moon phases. The picture demonstrates where the Moon is located in regard to the Earth and how the Moon appears to us.

### Example Question #9 : Reveal Patterns In Length And Direction Of Shadows

When the Sun shines on the telephone pole, a shadow of the telephone pole is cast. At different times of the day _________ .

the shadow remains in the same place and has the same length

the shadow will be at a different place and have a different length

the shadow will be at a different place

the shadow will have a different length

the shadow will be at a different place and have a different length

Explanation:

Patterns within shadows can be seen by measuring the length and direction and comparing them daily. The Earth's rotation causes the shadows to change throughout the day. The rotation of the Earth also causes day and night. The Earth's revolution causes slight changes in the length of these things because of its location in orbit. The correct answer is "the shadow will be at a different place and have a different length" because of the movement of the Earth.

### Example Question #10 : Reveal Patterns In Length And Direction Of Shadows

The rotation of the _______ on its axis causes the position and length of the shadow to change.

Moon

Earth

Sun
