Observing Daylight Through Seasons - 1st Grade Science

What observation shows that days are getting shorter over time?

Sunset happens earlier each day. Less evening light means shorter days.
Which observation best shows longer daylight: earlier sunrise or later sunrise?

Earlier sunrise. The Sun rises sooner when days are longer.
Which happens earlier in summer compared with winter: sunrise or sunset?

Sunrise happens earlier. Summer days start earlier and end later than winter days.
What is a record in science when studying daylight during the year?

Written or drawn notes of observations over time. Scientists document patterns by keeping detailed notes.
Which month is more likely to have longer daylight in the Northern Hemisphere: January or July?

July. July is summer in the Northern Hemisphere.
What is the name for a record that shows sunrise and sunset times across many days?

A data table (daylight data record). Tables organize sunrise/sunset times by date.
Which record best shows daylight change: a sunrise/sunset chart or a list of lunch foods?

A sunrise/sunset chart. Sun times show daylight patterns, not meals.
Identify the tool you use to record sunrise and sunset times each day: clock or thermometer?

Clock. Time measurement is essential for tracking daylight.
Which graphic best shows daylight changes across months: a line graph or a single picture?

A line graph. Lines connect data points to show trends over time.
If sunset changes from $5{:}00$ to $5{:}30$ , what happens to daylight time?

Daylight increases by $30$ minutes. Later sunset adds $30$ minutes of evening light.
Identify the best way to keep a daylight record for many days: one note or daily notes?

Daily notes. Multiple observations track changes better than one.
What does the word "daylight" mean when you are making observations?

The time from sunrise to sunset. It's the period when the Sun is visible in the sky.
Which happens later in summer compared with winter: sunrise or sunset?

Sunset happens later. Summer days extend later into the evening than winter days.
Identify the best evidence that days are longer: more daylight hours or more clouds?

More daylight hours. Daylight duration shows day length, not weather.
Which season usually has the fewest daylight hours in a year?

Winter. The Sun sets earliest and rises latest in winter.
Which has more daylight: a day with a later sunset or an earlier sunset (same sunrise)?

A day with a later sunset. Later sunset extends the total daylight hours.
What happens to daylight hours from winter to summer in the same place?

Daylight hours increase. Earth's changing tilt makes days grow longer.
Which statement is correct for most places: winter sunset is later than summer sunset, or earlier?

Winter sunset is earlier than summer sunset. Shorter winter days end earlier in the evening.
Identify the season if daylight is getting longer each day in your records.

Spring. Days grow longer as Earth tilts toward summer.
Which option best describes sunrise time in summer compared with winter: earlier or later?

Earlier. Summer days start earlier than winter days.
Which season usually has the least daylight: summer or winter?

Winter. Earth's tilt makes winter days shorter than summer.
What should you do first to compare daylight in two months using records?

Look up sunrise and sunset times for both months. Data comparison requires finding the times first.
What does a longer shadow at the same time of day usually show about the Sun's position?

The Sun is lower in the sky. Lower Sun angles create longer shadows.
Identify the season if daylight is getting shorter each day in your records.

Fall (autumn). Days grow shorter as Earth tilts toward winter.
Identify the correct comparison: Is daylight longer when sunset is later, or when sunset is earlier?

Daylight is longer when sunset is later. More hours pass between sunrise and later sunset.
What is night?

Time when the Sun is below the horizon and it is dark outside. The Sun's position below the horizon creates darkness.
Which season is most likely if it is still light outside at a late evening time?

Summer. Long summer days keep sky bright into evening.
Which season usually has the fewest hours of daylight: summer or winter?

Winter. Earth's tilt gives winter the shortest days.
Identify the pattern: If sunset is later each day, what happens to total daylight time?

Total daylight time increases. Later sunsets mean more hours of daylight.
Which line on a graph should rise if daylight is increasing over days: daylight hours line or date line?

Daylight hours line. More daylight makes the hours line go up.
Which season usually has the most daylight: summer or winter?

Summer. Earth's tilt gives summer longer days than winter.
What does a shorter shadow at the same time of day usually show about the Sun's position?

The Sun is higher in the sky. Higher Sun angles create shorter shadows.
Which option is a correct way to compare daylight in two months using a record?

Compare the sunrise and sunset times for the two months. Time records show daylight differences between months.

Which season usually has the least daylight in a year: winter, spring, summer, or fall?

Winter. Days are shortest when Earth's tilt faces away from the Sun.
What happens to the time of sunset from winter to summer in most places?

Sunset becomes later. Longer days mean the Sun sets later in the sky.
What happens to daylight time from summer to winter in most places: increase or decrease?

Decrease. Days get shorter as Earth's tilt changes toward winter.
Which season is most likely if it is dark outside in the early evening?

Winter. Short winter days bring darkness by early evening.
What happens to the time of sunrise from winter to summer in most places?
