SPACE AND WEATHER Sarah Burns Science 2 nd Grade

INTRODUCTION TO THE SOLAR SYSTEM In this unit we will be learning about space and weather. We will learn about a range of topics, from stars to what causes day and night to the water cycle. There our six lessons through this presentation with quizzes throughout to test how you are learning this new information. When this unit is completed you will be able to earn a digital badge to show all of your hard work, and improvement.

LESSON ONE – THE NIGHT SKY A star is a big ball of hot gases. A constellation is a group of stars that form a star picture. A planet is a large ball of rock or gas that travels around the sun.

STARS  The hot gases of the stars give off the light that we see.  Some stars seem brighter than others because they are bigger or hotter.  They also may look brighter because they are closer to Earth.

CONSTELLATIONS  The sky has about 88 constellations.  There are three very well known constellations  The big dipper  The little dipper  And Orion the Hunter

PLANETS  There are eight planets, including the Earth  All the planets travel around the sun  Together, the sun and the planets make up our solar system

LESSON TWO- DAY AND NIGHT Solar Energy Earth’s Rotation

SOLAR ENERGY  Like other stars, the sun is made of hot gases.  These gasses are so hot they give off light and heat, which are types of energy.  Most living things on Earth use solar energy.  Plants use the sun’s light to make food  Animals and people use its light to see in the daytime.  The sun’s heat warms water, land, air, and all living things on Earth.

EARTH’S ROTATION  The spinning of the Earth is called its rotation.  It takes 24 hours for the Earth to rotate one time; One full day.  The sun is always shining, but not always on our part of the Earth.  The rotation of the Earth causes each part of Earth to have light and dark each day.

LESSON THREE- MOONLIGHT Moonlight

THE MOON  The moon seems to give off its own light.  In reality, the light from the moon comes from the sun.  The moon takes about 29 days to orbit the Earth.  The moon has craters, which are made when a large rock moving through space hits the moon.

LESSON FOUR- PHASES OF THE MOON  The moon’s orbit makes the moon seems to change shape.  At the start of the moon’s orbit, the moon is between the sun and the Earth.  The sun shines directly on the part of the moon facing the sun, so the side facing earth is completely dark. This phase is called the new moon.  As the moon orbits around the Earth, you begin to see more and more of the moon until it is a full moon. New Moon Full Moon

LESSON FIVE– WHAT CAUSES SEASONS? Earth’s Orbit Why the seasons change

EARTH’S ORBIT AROUND THE SUN  Earth moves in a path around the sun, called an orbit.  It takes one year to orbit the sun.  As the Earth orbits the sun, the seasons change.  The Earth rotates on an imaginary line called an axis.  A season is a time of year that has a certain kind of weather.  The four seasons are: Fall, Winter, Spring, and Summer.

WHY THE SEASONS CHANGE  The Earth is always tilted in same direction.  When Earth is on one side of the sun, part of Earth faces the sun directly and gets more sunlight. The part of the Earth is in summer.

CHANGES IN WEATHER SpringSummerFallWinter

SPRING  The air gets warmer  Some places get rainy  Warmer, wetter weather helps plants grow new leaves and flowers

SUMMER  Warmest time of the year  Hot and sunny  Storms make the weather change quickly

FALL  Air gets cooler  Some days are cloudy, some are clear  The leaves change colors and then drop off  Some plants die

WINTER  Coldest time of the year  Some places get snow  Many trees and bushes have bare branches  Other places it cools down  Rarely have snow  Trees stay green  Flowers keep growing

LESSON SIX- THE WATER CYCLE  Water moved from the air to the land and back to the air. The way water keeps doing this over and over is called the water cycle.

HOW THE WATER CYCLE WORKS STEP 1) The sun’s heat makes water evaporate, or change into a gas. STEP 2) This gas, or, water vapor, meets cool air. STEP 3) The water vapor condenses, or changes into tiny drops of water.

HOW THE WATER CYCLE WORKS (CONT.) STEP 4) The drops of water come together and form clouds. STEP 5) The water drops become heavy and fall as rain or snow. STEP 6) The rain and melted snow flakes flow into streams, lakes, and oceans.
