The sun gives a rhythm to our lives – day follows night, shadows grow shorter and longer, the seasons follow a regular progression over the year. We are adapted to these daily and seasonal changes, and our lives are structured around them. Bats hunt at night and dragonflies in the daytime, leaves turn colors in the fall, buds swell in the spring. Whether plant or animal, diurnal or nocturnal, all living things depend on the sun for providing heat and light and making our planet habitable. Continue reading Sunlight and Shadow – Background
**Caution: It is not safe to look directly at the sun!**
FOCUS: As the Earth spins on its axis and travels around the sun, we experience day and night and the seasons. The sun’s rays give us energy in the form of light and heat. Solar energy warms the Earth, fuels the water cycle, and generates our weather systems. It provides the energy for plants to carry out photosynthesis, the basis of food chains and webs, and the conditions in which living things can exist. Through engineering we can also harness the sun’s energy for our own uses.
Introduction: What are some things the children have noticed about the sun? (If convenient, bring children outside to do “Eyes Closed” and “Tracing Shadows” to begin with, and then revisit the shadow tracings later.) Continue reading Sunlight and Shadow – Activities
The Sun is Falling!
Characters: Gracie Grouse, Myrtle Turtle, Honeybee, Rosie Raspberry, Benjy Bear.
Gracie Grouse Squawk, squawk! Look out, look out! The sun is falling! The sun is falling!
Myrtle Turtle: The sun is falling? How do you know, Gracie Grouse?
Grouse How do I know? Why, it was high up above my head just a little while ago. And now look, it’s halfway down the sky. It must be falling down! Continue reading Sunlight and Shadow – Puppet Show
SUNLIGHT AND SHADOW ALIGNMENT WITH
NEXT GENERATION SCIENCE STANDARDS
The activities in this unit help children understand the basic concepts in the Disciplinary Core Ideas listed here. You can use the following list as a guide for lesson planning. These Disciplinary Core Ideas are taken from Grade Band Endpoints in A Framework for K-12 Science Education. Additionally, our activities give children opportunities to engage in many of the Science and Engineering Practices and reflect on the Crosscutting Concepts as identified in the Next Generation Science Standards.
