The visit to the National Science Exhibition was a really rewarding experience. Since I was a kid I have been always attracted to science, specifically chemistry, because I have always had a lot of questions about how everything is composed. In the Exhibition I could see many experiments which show in an easy way how to understand chemistry in a simple way, for example I learnt how to turn on a lightbulb with copper and a potatoe.
This event opened my mind and now I am sure I want to be a scientist.
Sentence 3 is correct. "Every time I see you, he laughed, you are on the phone." They are laced correctly there. he pauses after he says "ervy time I see you" Then he pauses to laugh, then he continues. 3 is correct.

Stage 1- Stars are born in a region of high density Nebula, and condenses into a huge globule of gas and dust and contracts under its own gravity.

Stage 2 - A region of condensing matter will begin to heat up and start to glow forming Protostars. If a protostar contains enough matter the central temperature reaches 15 million degrees centigrade.
This image is the outflow (coloured red)and protostar.
Stage 3 - At this temperature, nuclear reactions in which hydrogen fuses to form helium can start.
Stage 4 - The star begins to release energy, stopping it from contracting even more and causes it to shine. It is now a Main Sequence Star.

Stage 5 - A star of one solar mass remains in main sequence for about 10 billion years, until all of the hydrogen has fused to form helium.
stage 6 - The helium core now starts to contract further and reactions begin to occur in a shell around the core.

YESSSSSSSS . How old are you? I’m 16. Also what’s your hobbies ?
It could be the first or the third answer but i am not sure you probably have to look up the words to find what it could be
