Positions of the Sun and Shadow

Socioemotional Summary Conclusion

Goals

1. Understand how Earth’s rotation influences the changes in shadows throughout the day.

2. Identify and name the emotions that emerge during scientific exploration and group learning.

3. Enhance observation and description skills by recording the shifting nature of shadows.

Contextualization

 Have you ever stopped to notice how your shadow changes as the day goes on? In the morning, it appears long and stretched out, while at noon it’s much shorter. These changes aren’t random—they result from the Earth spinning on its axis. Imagine understanding this fascinating natural phenomenon and connecting it to the feelings we experience every day! Ready to explore together? ‍♂

Exercising Your Knowledge

The Earth's Movement

Our planet rotates on its axis—a motion known as rotation—which is what creates day and night. This continuous spin, taking about 24 hours to complete, is why the sun appears to move across the sky and why shadows change as the day progresses.

  • The Earth rotates continuously over a 24-hour cycle.

  • This rotation brings about the cycle of day and night.

  • It causes the sun’s apparent movement, which in turn influences the length and direction of shadows.

The Sun's Position

Thanks to Earth’s rotation, the sun seems to traverse the sky. It rises in the east in the morning, reaches its peak at noon, and sets in the west in the afternoon. These daily shifts determine not only the sun’s position but also the size and direction of the shadows we see.

  • In the morning, the sun rises in the east and casts long shadows.

  • At midday, when the sun is highest, shadows shrink considerably.

  • By the afternoon, as the sun sets in the west, shadows lengthen once more.

Shadow Formation

Shadows form when an object obstructs sunlight. As the sun moves, the angle and length of these shadows change. For instance, a tree’s shadow will be longer in the early morning and late afternoon, but much shorter around noon.

  • Shadows are created when something blocks the sunlight.

  • The shadow’s length and direction change with the position of the sun.

  • Observing these patterns can deepen our understanding of Earth’s rotation.

Key Terms

  • Earth's Movement: The rotation of the Earth on its axis, resulting in day and night.

  • Sun's Position: The sun’s apparent path across the sky, influenced by Earth's rotation.

  • Shadows: Dark areas created when an object blocks the sunlight.

For Reflection

  • How do you feel when you notice your shadow changing throughout the day? Are you curious, excited, or maybe pondering why these changes occur?

  • Consider the part of the day when you feel most energetic—be it morning, afternoon, or evening. How might this relate to the sun’s journey and the shadows around you?

  • When learning in groups, how can discussing the movement of shadows and the sun help us understand each other’s emotions better? Can you share an example from your own experience?

Important Conclusions

  • The Earth’s rotation is key to the cycle of day and night.

  • The sun’s position in the sky varies throughout the day, influencing how shadows fall.

  • Shadows form when an object blocks sunlight, offering insights into Earth’s consistent rotation.

  • The dynamic changes in shadows can mirror our fluctuating energy levels and moods.

  • Observing natural phenomena like these sharpens our abilities to observe, reflect, and regulate our emotions.

Impacts on Society

Observing how shadows change and noting the sun’s path can directly influence our daily routines. For instance, understanding these natural patterns helps us plan outdoor activities or decide the best times for studying or playing. It also deepens our connection with nature and sparks scientific curiosity, encouraging us to explore the world around us. ‍♂

‍‍‍ Recognizing how the sun’s movement ties into our emotions is equally valuable. When we notice the effect of sun and shadow on our mood and energy levels, we learn to manage these feelings better, making more informed choices about our time and interactions with those around us. 

Dealing with Emotions

 To help manage your emotions while exploring this lesson, try an exercise based on the RULER method: As you observe shadows at different times of the day, take a moment to check in with yourself. Ask, 'Am I feeling energized, curious, a bit tired, or excited right now?' Reflect on what might be triggering those feelings—is it the angle of the sun, the day's warmth, or simply the excitement of a new discovery? Naming your emotions clearly and even sharing these insights with a friend or family member can be really beneficial. Finally, find a way to balance your mood—maybe by taking a refreshing walk outside if you need a boost, or pausing for a break if you’re feeling drained. ⭐

Study Tips

  • Keep a log of how shadows change at different times at home or school. Sketch what you see and note the time to compare your observations.

  • Start a small journal to record your emotions at various points during the day, linking them to the observed changes in shadows and the position of the sun. This can help you notice patterns in your mood.

  • Discuss your findings about the sun and shadows with family and friends. Explaining your discoveries is a great way to deepen your understanding and strengthen your communication skills. 
