Earth makes a full rotation, or spin, in one day.

• Earth orbits, or moves around, the sun

• The Earth orbiting the sun takes one year!

1. Spring

2. Summer

3. Fall

4. Winter

They are caused by the Earth's orbit around the sun and its rotation!

• This happens in the morning

• This happens around nighttime

• The entire Moon is shown!

• Moon is between Earth and the Sun.

  • You don't see any Moon or its a shadow of the Moon

• Sometimes called "half moon" because you can only see the left half of the moon

• Sometimes called "half moon" because you can only see the right half of the moon

• There is a thin crescent on the right side

• Allllmost the entire moon is shown. Just a little sliver of it on the left has a shadow

• There is a thin crescent on the left side

• Allllmost the entire moon is shown. Just a little sliver of it on the right has a shadow

be predicted.

1-ESS1-2 Make observations at different times of year to relate the amount of

daylight to the time of year. **

Planning and carrying out investigations to answer questions or test solutions to problems in K–2 builds on prior experiences and progresses to simple investigations, based on fair tests, which provide data to support explanations or design solutions.

• Make observations (firsthand or from media) to collect data that can be used to make comparisons.

Analyzing and Interpreting Data

Analyzing data in K–2 builds on prior experiences and progresses to collecting, recording, and sharing observations.

• Use observations (firsthand or from media) to describe patterns in the natural world in order to answer scientific questions.

• Seasonal patterns of sunrise and sunset can be observed, described, and predicted.

ESS1.A: The Universe and its Stars

• Patterns of the motion of the sun, moon, and stars in the sky can be observed, described, and predicted.

• Patterns in the natural world can be observed, used to describe phenomena, and used as evidence.

 Connections to Nature of Science

 Scientific Knowledge Assumes an Order and Consistency in Natural Systems

• Science assumes natural events happen today as they happened in the past. 

• Many events are repeated.
