PES 1.5: Investigating Size and Distance

Objective: KWBAT use models to visualize and make measurements about to explain when stars are in the sky and why stars appear to be different sizes in the sky.
1

When can you see stars other than the sun?

1

Which star is visible (can we see) during the day?

Criteria For Success (CFS)

Data Table 1
1

What information does Data Table 1 tell us about the distance of the sun compared to other stars?

Sentence starter: The distance of the earth to the sun is _________________ compared to the other stars.

Data Table 2
1

What information does Data Table 2 tell us about the size of the sun compared to most of the other stars?

Sentence starter: The size of the sun is _________________ compared to most of the other stars.

Investigating Question: If the stars are all around us, why can't we always see them?

Investigating Stars in Daytime and Nighttime

In order to answer our investigation question, we’ll use the Patterns of Earth and Sky Simulation to investigate what might be different between nighttime, when we can see many stars, and daytime, when we can only see the sun.

Directions:
1. Open the Patterns of Earth and Sky Sim by on the website https://apps.learning.amplify.com/patternsofearthandsky/
2. Turn “Daytime Star Positions” to ON.
3. Look at the top right corner. Make sure the speed is in HOURS and press the PLAY button.
4. Take your hands OFF your Chromebook and observe the stars in SKY VIEW, both in daytime and nighttime.
5. Use your observations to answer the questions below.
1

Which star(s) do you see in the Skyview during the daytime?

1

Which star(s) do you see in the Skyview during the nighttime?

1

Is the sun the only star in Sky View during daytime?

Size and Distance Investigation

Remember, creating models can help scientists investigate their questions and better understand how things work. We will also use the strategy of visualizing with this model to see if that improves our understanding.

DIRECTIONS:
  • Watch the teacher created model video.
  • Use the information from the model to answer the questions below.
1

Based on the model, why do some stars appear to be smaller when we view them from Earth?

Use the data table below to answer this question.

  • What do the numbers (data) show?
1

Is the sun larger than most of the other stars outside our solar system?

Use the data table below to answer this question.

From Earth, why does the sun look so much larger than other stars?

Sentence Starter: The sun looks much larger than other stars because _________________
