I made this model of an Oxygen Atom. The middle is called the nucleus. It has protons and neutrons, 8 of each. It’s atomic number is 8. Within the first shell there are 2 electrons and in the outer shell there are 6 electrons.
Here is a link to me talking about Hypervolocity Stars.
THE BIG BANG
Years ago many scientists believed that the universe was infinite and unchanging. Now we know the universe was created in a giant explosion called the big bang. Lots of particles were flying around, these particles collided to form protons and neutrons. Protons and neutrons collided to form atoms and atoms used their magnetic pull to capture electrons.
THE FORMATION OF STARS
Next the atoms formed clouds of gas and dust, these started to circle around each other and then they started to collapse. Soon the core of all the dust and gas became so hot that it could sustain thermal nuclear fusion. Thermal nuclear fusion means that small atoms collide to form big atoms. A star the size of are sun will fuse up to carbon while more massive stars will fuse up to iron.
THE FORMATOIN OF GALAXIES
Now we’ve created stars we can form galaxies. The stars have a very strong magnetic field so they can pull themselves towards each other, as they pull they come closer and closer together soon they form a galaxy. This will keep on going to form lots and lots of galaxies.
THE FORMATION OF SOLAR SYSTEMS
Now atoms collide to form rocks and rocks will collide to form rocky planets. The leftover rocks collide to form a core gas and dust swirls around the core and the core uses its magnetic pull to grab the dust and gas this keeps on going until it forms a gas giant (like Jupiter), the ice giants(like Uranus) are formed in the same way as rocky planets do. Our solar system contains planets called mercury, Venus, earth, mars, Jupiter, Saturn, Uranus and Neptune.
THE END OF THE UNIVERSE
We’ve got everything you have in a universe and so you might be thinking how it will end. Some people believe that dark energy may be the driving force, if so the universe will rip apart. However some people believe that dark matter is the driving force if so the universe will collapse in on itself. Very few people believe that both of the forces are balanced but if so the universe will become infinite.
So that was the end of a tutorial of the universes time line I hope you enjoyed reading this and you learned a lot so goodbye.
This morning I made my Fraction Flip Chart. It shows how to see the different fractions from a whole to 12th’s. I made it using my protractor. I drew a circle, then marked the lines where I had to draw. I did the division sum first to figure out what number of degrees each section would need to be. I laminated them next and Daddy used a treasury tag to hold them together. A whole circle is 360.
Here is my calendar that works forever. It works forever because it’s got the most days in each month, so February has 29 days. Normally February has 28 days but in each 4 years it has 29 days,because it’s a leap year. I think it is funny if you are born on the 29th of February because you would have to wait 4 years until your birthday. It’s good that I wasn’t born on the 29th of February because I would only have had 1 birthday even though I am 6 years old.
Today, we did an experiment to see how long it took for water to go from boiling to freezing. First we filled a bowl up with water, then we boiled it in a pan and then put it in the freezer.
We used a temperature probe to measure how cold or hot the water was. I made a graph showing the temperature and time. We checked it and plotted it every 10 minutes. It took 140 minutes to freeze which is 2 hours and 20 minutes.
I really did have lot’s of fun working on an experiment.
