We are currently working on a report on some aspect of Space Travel. We used theis presentation as a starting point. To view the presentation again please click on the link below.
Some boys have created there own presentations on the theme of Space Travel:
Spacerace USA Vs Russia by Adrian
The First Landing on the Moon by Matthew
Description: Earth is in 75 % covered with water.
Location: Earth is 3rd planet from the sun.
Planet Facts: Earth is home for million of species. The planet formed 4.54 billion years ago.
Earths orbital speed is 18 107 218 km/h.
Earth is 1 out of 4 planets between The Sun and the asteroid belt.
DESCRIPTION: Earth contains 78% nitrogen , 21% oxygen and less than 1% carbon dioxide.
LOCATION:It is the third plannet from the sun.
PLANET FACTS:
The Revolution period is 365.2 Days.
The rotation period is 23.9 hours.
The equatorial diametre is 12,756.
The Gravitational pull is .98 (your current weight) and the only satelite is the moon.
If the earth was any closer to the sun it would be too hot but where it is situated now is just perfect because if it was any further away it would be too cold.
For example it would be too hot on Venus but it would be too cold on Mars.
Neptune is the last gas planet. It’s gravity is almost the same as Earth. It’s atmosphere is filled with methane, that is why it also has a blue colour. It has one great spot, the Dark Spot it is believed to be a storm. Neptune is the eighth planet away from the sun. Neptune is 4,495,100,000 km from the sun, it takes 59,800 days to travel around the sun, it’s gravity is 1.1 times Earth’s gravity. Neptune has 48 moons and the three main moons are Nereid, Protues and Triton.
Description. You will know it’s Jupiter because of the”red spot”on Jupiter’s surface.
Location.Jupiter is the fifth plant from the Sun.
Plant Facts. The ”red spot”on Jupiter’s surface is a storm and it can fit Earth 3 time’s.
Jupiter is 318 time’s bigger than Earth.
Jupiter is about 778million km from the Sun.
It takes Jupiter 9hrs 51mins to spin on it’s axis[lenght of day].
Jupiter is the biggest plant in our Solar System.
It take’s Jupiter 11yrs 315 days to go around theSun.
Jupiter has three rings but you can’t rarely see the rings.
Description:Venus is considered Earth’s twin sister because of the similar size. It rotates in the opposite direction of Earth. It has very dense atmosphere that reflacts the sunlight.
Location:Venus is the second planet from the Sun.
Earth is a small planet but it is not a dwarf planet.
Third planet away from the sun.
It is the only planet in the Solar System which has life in it.
Description: Uranus is a gas planet. Uranus has 11 rings and rotates on its side. Its atmospher is methan witch gives it its blue colour.
Location: Uranus is the seventh planet from the sun.
Planet Facts:
Solar distance: 2,872,500,000km from methan sun.
Revolution period: 30,589 days.
Rotation pireod: 17.2 hours.
Equator diameter: 57,118km.
Gravitational pull: .87 of earths gravity.
Satelites: Uranus has 21 moons witch take the names of writers.
It’s round and has lots of land.
location: 3rd planet from the sun.
It takes 23.9hours to rotate on its axis
.
Description:blue and green.
location:3rd planet from the sun.
planet facts:75% of Earth is full of water and is probobly the only planet with life.
For science this week we are studying the effect that exercise has on our heart and pulse rate. We learned how to measure our heart rate by counting the beats of our hearts over a period of one minute. We did this by holding our fingers to the pulse point on our wrists. We then exercised using skipping ropes for a period of 5 minutes, after which we measured our heart rate again, in order to make a comparison.
Log in and answer the following question by posting a comment. Think about it before you answer!
Q. Can you come up with a way of measuring your heart rate for a period of one minute without having to count to sixty?
As part of our science class today we conducted an experiment to show how our diaphragm helps us to breathe in and out. We used a plastic bottle and two balloons to show how our diaphragm forces air in to and out of our lungs.
