  1. Weather Unitby Jonathan Hamilton Chapter 4

  2. Changing Seasons • What changes occur in the fall to remind you that seasons are changing? • What changes occur in the spring signal the changing seasons? • How does the changing of seasons affect you?

  3. The Tilting Earth • What is the name of the imaginary longitude line running from the North pole to the South Pole? • What is the name of the imaginary latitude line running through the middle of the Earth?

  4. Kinesthetic Astronomy

  5. Weather Acronym – Make your Own! • W ind vane – device that shows wind direction • E l Nino – cool waters of the Pacific cool off the coast of South America become warmer about every 4 years • A ir – the push of air against its surroundings • T ropical Climate – usually hot and rainy year round • H igh Pressure Areas – areas where pressure is higher than the surrounding air • E quator – imaginary line that circles the middle of the earth • R elative Humidity – the amount of water vapor the air is holding compared to the amount it could hold at that temperature

  6. Seasons in the Sun • The seasons change as the Earth revolves around the sun. • Watch it! Earth Revolving Around the Sun • Look at the picture to the right. What is the difference between Rotation and Revolution?

  7. Pointing towards the North Star • What is the name of the star that the North Pole is always pointing towards? • The sun always rises in _____ • and sets in the ______.

  8. What is a Hurricane? E70-E71

  9. The fiercest storms on earth… • I will print out some worksheets from this site for you to do! • Hurricane Worksheets • Read this link about how to make your house Hurricane Resistant: Prevent a Disaster • True or False? A hurricane forms as it takes in cold air and moisture from cold Ocean water • What is the middle of a hurricane called?

  10. Will your house survive the hurricane? • Prepare this house for a hurricane: • Hurricane House • Hurricane Cartoon • More Hurricane Cartoons

  11. Watch a hurricane video! • Hurricane Video Website

  12. Tornado Tube • Procedure: • Fill a plastic soda bottle about two-thirds full of water • Screw one end of a tornado tube onto the bottle. Make sure the end fits tightly. Then screw an empty bottle into the other end of the tube. • Turn the bottle with the water in it upside down. Hold on to the tornado tube. Quickly move the bottles in five or six circles so that the water inside swirls. • Which way does the air in a tornado spin?

  13. Tornado!

  14. Beaufort Scale

  15. The Water Cycle E44-E47

  16. Water Cycle and Precipitation • What is it called when water changes from a liquid to a gas? Example? • What is it called when water changes from a gas to liquid water? Example? • What is billions of tiny drops that are condensed from the air? • What is the amount of water vapor in the air?

  34. Investigation Review • What are biomes? • In the warmest climates there are lush _________ where it rains almost every day. • What a contrast to the _________ which can also be very hot, but where it rains hardly at all. • Farther north the _________ ________ grow. There the winters are cold but the summers are warm and wet. • Even farther north you find coniferous forests and the _____ where the subsoil stays frozen all year.

  35. Caddisfly Larvae • Larvae measure up to 3/4 inch in length. • Three pairs of legs. • Body is caterpillar-like and strongly curved. • Antennae reduced and inconspicuous. • Color varies from bright green to dark brown.

  36. Mayfly Nymphs • Can take from three weeks to two years to become adults. • Nymphs of many species vibrate their gills to increase the amount of water moving over them (this is the equivalent of panting). Their gills may also be used as swimming paddles. • Adult Mayflies have male and female sexes, but in some species the females can lay unfertilized eggs (without male interaction) that hatch into more females.

  37. Stonefly Nymph • Adult Stoneflies live only for a week to a month, and females live longer than males. • Stonefly nymphs have two long tails or cerci (sir-key), whereas Mayfly nymphs have three long tails. The cerci are sense organs but also help the insect to move. • Stonefly nymphs have tubes of thread-like gills on their underside, wing pads and antennae (feelers). • Each leg has two claws that are used to cling to rocks or sticks. • Their bodies are streamlined so they don't get swept away by the water current.

  38. Dragonfly Nymph • It breathes by sucking water into its abdomen to move water over its internal gills. Once it has absorbed enough oxygen, the nymph squeezes the water out rapidly so it does not have to come up for air like most pond insects. This also helps propel them forwards in the water. • Much of a dragonfly's life is spent in the larval stage where it moults six to 15 times. The nymph crawls out of the water and moults one last time, emerging as an adult with functional wings. Dragonflies and damselflies do not go through a pupal stage to become an adult. • They keep the populations of mosquitoes and flies under control.

  39. Midge Larvae • Midge Larvae can tolerate organic pollution as they feed on the organic particles. They can live in water having low levels of dissolved oxygen as they can rise to the surface to breathe. • Even a drop of water is enough to sustain a Midge Larva.

  40. Rat Tailed Maggot The rat-tailed maggot usually breeds in drains, sewage pools, and other stagnant water. Although the larvae live on decaying organic matter, they must breathe air. For this, the breathing tube (the tail) is extended or contracted depending on the depth of the liquid in which they are feeding. Learn more about bugs: Buglopedia

  41. Properties of Matter B2-B64

  42. Matter, Matter, Everywhere • What is a property? • What are the physical properties of a material? • What are the chemical properties of a material?

  43. Why do you see lightning before you hear the thunder? What is the safest place to be in a lightning storm?

  44. True or False? Lightning causes the air around it to become more than five times as hot as the surface of the sun!
