In this unit, students have been analyzing weather patterns and seasons as well as considering the role of the sun in heating the Earth.

This page provides a brief overview of lesson two of this unit, in which students conduct two investigations and use the patterns they discover to make predictions about the future positions of the sun, moon, and stars in the sky. In the first investigation, students observe the sun’s position in the sky at different times of day, drawing a diagram (model) of the sun’s position above the horizon. In the second investigation, students use a sundial model to explore the relationship between the sun’s position and the length of shadows.](https://www.knowatom.com/science-phenomena-videos/1st-grade-science/sun-position-and-shadow-patterns) [ VIEW LESSON ](https://www.knowatom.com/science-phenomena-videos/1st-grade-science/sun-position-and-shadow-patterns) [![](https://www.knowatom.com/hubfs/image3-Oct-18-2023-10-46-31-5099-AM.png) ](https://www.knowatom.com/science-phenomena-videos/kindergarten-science/windy-weather) ## [Windy Weather In kindergarten, students begin to develop the practices that scientists and engineers use to help them answer questions and solve problems.](https://www.knowatom.com/science-phenomena-videos/kindergarten-science/windy-weather) [ VIEW LESSON ](https://www.knowatom.com/science-phenomena-videos/kindergarten-science/windy-weather) Standards citation: NGSS Lead States. 2013. *Next Generation Science Standards: For States, By State*s.
