Kindergarten, Science, Week 37

• Read about Day 7 of Creation from The Creation
• Discussed that God rested from His work of creation, but He is still working in our world and lives.
• One way God is working in our world is the weather
• Started reading The How and Why Book of Weather by George Bonsall copyright 1960
• Sun + Air + Water = Weather
• Air takes us space
• Experiment of upside down glass into bowl of water; no water goes into glass because it is full of air
• Air is real
• Blow up a balloon; you can feel the air when you press on it
• Air is heavy; the pressure in our bodies is equal to the air pressing down on us, so we don't feel the weight of the air
• Hold a paper napkin with two hands; your child can easily poke a hole through it with 1 finger
• Hold another paper napkin; have your child push with a finger from each hand at the same spot from each side of the napkin (one finger on each side of the napkin). No hole is made because the pressure on both sides of the napkin is the same.
• Air presses down
• At sea level the molecules of air are squished closer together than high in the sky
• If you had a stack of pancakes 3 feet high, the pancakes at the bottom get squished by the pancakes above them. If you took two inches of pancakes from the bottom of the stack you would get more pancakes than if you took two inches from the top.
• The sun heats up the earth during the day; the earth cools off at night
• Winter
• Days are shorter than nights (earth has longer time to cool)
• Sun shines on earth at a slant (sun's rays are spread over a larger area and don't give as much heat as when the sun shines straight down as in the summer)
• Spring
• Days are becoming longer/Nights are becoming shorter
• Summer
• Longest days/shortest nights
• Direct rays of the sun strike the earth, bringing more heat
• Autumn
• Days are becoming shorter/Nights are becoming longer
