Flame Lab

This week our class did an interesting lab which involved fire and some substances from the periodic table. The question was, what color or affect would the substance do when put over the Bunsen burner. For example,when strontium was put over the fire it made the flame turn red. One substance made the fire turn green but unfortunately I couldn't recall what it was. All the substances will make a different color. They use them in fire works. I found that really interesting because i did not know that. I really enjoyed this lab

Law of conservation and mass

This week we did a lab that involved using many different chemical and masses. We used a mass measuring box to measure the mass of the chemicals in the tubes. We used the tubes to mix the chemicals inside. First we would weigh the substances individually and then after we mix, then we measure the mass of the combined chemicals. Sometimes it would make quite a diffidence but sometime it wont. One of the chemical we tried was a water bottle and these tablets which make a gas. First we measure the tablet in the cap of the water bottle. Then we put the tablet in, and sealed the bottle. The gas that was being made, was making the water bottle full of gas. I was afraid it would pop but it didn't.

Reflection on big bang theory

The big bang theory is what happend billions of years ago which made all planets and stars in our solarsystem. Its the event that started life on our planet. Some stars are bigger than ever but the ones that starts solar systems are the big ones. Most of the stars made were small but the big ones have a gravitational pull. That is how planets go around the sun in a circle.

The big bang formed giant rocks, astroids, moons, and planets. The astroids are not big enough to grasp the gravity from the sun so they normally just float around in space. Our planet is the only planet that can contain life in our solarsystem as far as we know. The light from the sun is the source of life in the planet. The first kind of life that was made was many plants and dinosaurs. Sadly the dinosaurs became extinct from a giant astroid that worked as a nuke to kill all the dinosaurs but its also a good thing because our species then came along, and also many mamals.
