In my opinion, dissections are gross and I will never do them (unless I have to). But we should be glad scientist, doctors, and veterinarians can cut open people and animals to look to see if they had a serious infection. Let’s say that you died of an unnatural cause and you donated your body. We might find out why and how you died. We also might find a cure for it. We also need to know where organs are and what they do to help support us. In groups, dissections can actually help you learn a lot like team work, and you may remember stuff more by actually touching and cutting the animal open. Also we can study more about blood cells, and why blood clots occur. If we learn more about that, we may start eating healthier. That’s why I think dissections are important.

My blog is going to be about my semester project. The problem was, which substance reacts the fastest when added to baking soda? I learned that baking soda just doesn’t react to vinegar, it reacts to different sorts of liquids, like grape and lemon juice, and even coke. I liked how the experiment turned out, to where even though it sounded hard with putting the baking soda in and then starting the stop watch, it was actually pretty easy. One thing that I wish I knew more about, is the chemicals that reacted with the baking soda. Why did those two things happen to react. What caused them to react with each other? Well I guess that is all I have to say about my project, but here is a picture from the experiment.

Mountains. Are they really indestructible? I have that answer, and it’s no. Erosion can change rivers, plateaus, anything! The question though, is what will happen in a million years? I will be talking about Pike’s Peak, a mountain in Colorado Springs. I think Pike’s Peak must have started as a flat surface, and then when magma comes out of the ground when plates are moving, the magma cools and then more will sit and cool on top of it. In a few million years, either Pike’s Peak will get bigger, or erosion will cause it to get smaller, or while erosion acts upon and it keeps getting bigger, they will act upon each other and maybe not move at all. I think it will just repeat itself over the next few million years. Everyone has a different theory, and that was my theory.

What actually happened when the universe was created? Was it the Big Bang theory, a explosion which created the universe, or just an oscillating model, a theory which states that the universe began with an expansion occurring in all areas. Many people have their own beliefs, may it be the Big Bang, or the oscillating model, but mine is God. God easily said ‘Let there be light’, and it happened. He made mankind. He created the world so he had to create the universe. Scientist think they need proof to say that the Big Bang theory happened. Well, I have all the proof I need. It’s a book called the Bible. God created the world in six days, with the seventh day as rest. Everything in the Bible is true. If you need more proof, look around you. The Earth, the sky, the trees, the animals, and your family wouldn’t be here if it weren’t for Him. We’re proof that God made the universe. Anyone can have their own beliefs, but mine will always be God.

“I will say of the Lord. He is my refuge and my fortress:  In Him
       will I trust.”

When we see color changes, bubbles, gas, if you hear something that you didn’t hear before, feeling a temperature change, or if it smells different, or if it precipitates (or change forms) those are signs of a chemical reaction.  Those are signs of a chemical reaction. What really happens is that the first item is being mixed with another item and can’t be changed back. The atoms of that item are mixed together and form a whole new atom.

Lab safety and equipment. Why is it so important before you start an experiment? I can tell you in this blog. On lab safety, it is important to be safe so you can’t get maimed or in other words seriously hurt. Safety goggles protect your eyes when a chemical’s gas poofs up. You always pull your hair back so your hair won’t accidentally get caught on fire. Always pour the acid into the water or there might be a chemical reaction. Don’t eat or drink chemicals and when you need to smell one, don’t put your nose over the test tube, but waft the smell toward you. Dry your hands before you touch anything electronic, because who would want to get shocked? If you drop a glass test tube, don’t bend over and pick it up with your hands, use a broom and the pan. Wash off anything that gets on your skin, really fast if it starts burning. Well, that’s the main rules in lab safety. Have fun and be safe!
