Earth and Space Science - 1st Grade Science

There is a direct relationship between seasons and the number of daylight hours. During the spring and summer, longer days mean more daylight hours because of the Sun's tilt and position; during the winter, the days are shorter.

This is an untrue statement. The order of the seasons stays the same every year. The order is based on the Earth's revolution around the sun which does not change.

Spring and summer have the most daylight due to the Earth's position and tilt during these times. The days are longer which means more sunlight. During the summer solstice (the longest day of the year) parts of the world receive between 14 and 21 hours of sunlight!

The fall and winter have the least amount of daylight of the four seasons. The Earth's tilt and position cause the Earth to be tilted away from the Sun, so there is less sunlight, and the days are shorter.

The student is correct with his prediction. The Earth is slightly tilted, and during the summer, it is tilted towards the Sun, so we are warmer and get longer, sunnier days. During the winter, the Earth is tilted away from the Sun based on our position, so the days a colder, shorter, and there is less sunlight.

Rob can conclude that during the winter months, there is less daylight than during the summer months. If there are only 9 hours of daylight in the winter but up to 15 hours in the summer, there is a relationship between the seasons and the amount of sunlight based on this data.

The conclusion that is NOT correct is that spring and fall get the same amount of daylight. Looking at the data table, we can see that spring receives 13 hours of daylight, and the fall receives 11 hours of daylight. These are not the same number, so this is an incorrect statement. The other answer choices are true statements based on the data.

Daylight means the arrival of natural light from the Sun. When the Sun rises in the morning, it shines a light on Earth, which we call daytime. The amount of daylight that we receive depends on the season.

The month with the most daylight is in June. This month is during the summertime. The longest day of the year is actually in June, and some places receive 21 hours of sunlight that day!

This is a false statement. Winter is typically the coldest month and receives the least sunlight because of the Earth's tilt and location in its revolution. Summer is the warmest season and gets the most sunlight.

When observing the Sun, patterns can be noticed. The Sun appears to move through the sky during the day, but it is the Earth moving that makes it seem this way. The Sun always rises in the East and sets in the West. This is a pattern we can observe every day.

When observing the Moon, patterns can be noticed. The Moon appears to move through the sky during the night, but it is the Earth moving that makes it seem this way. The Moon always rises in the East and sets in the West. We can also see the Moon appears to change shapes as it goes through its phases every month.

Stars can only be seen during the nighttime. This is a pattern that can be observed each night. During the days the stars are not visible but when the Sun sets we can see the stars shining.

The patterns of motion that can be observed are the changes in position. The Sun and Moon both rise in the East and set in the West every day. The Earth is also continually rotating, so the objects in the sky appear to be moving.

Every month the Moon appears to change shape, but it is just the moon phases. The shadows on the Moon change throughout the month based on how much sunlight there is shining on the Moon's surface. This is a pattern that can be predicted because it repeats every month.

A pattern is something that can be observed happening over and over again. It is something that repeats the same way again and again. Patterns can be seen in nature, science, math, and everyday life!

The shape of the Moon does appear to change over a month in a predictable pattern. We call these moon phases. The Moon may appear to be full, only partly shown, or there may be no moon visible at all. This is because of the amount of sunlight shining on the Moon during that time of the month.

The Moon follows a predictable pattern over a month called the moon phases. Depending on how much sunlight is shining on the Moon, it will appear to change sizes.

We can make predictions based on patterns. When something happens every night (like the Moon rising in the East), we can make the best guess or a prediction that the same thing will happen again the next night.
