I think dissections are important in a science class, because it is a great hands-on activity that you can do to teach your class all about where different things are in an organism. As well as showing them what the organism has ate in the past few days. That is why i think that dissections are important in a class setting.

My Experiment
Well this was an interesting experiment and I learned that if you put candy in heated hydrogen peroxide the candy with the sour sugar coating will not react the most. What I would change if we had the chance to try the experiment again is that instead of the hydrogen peroxide we would use heated potassium clorate.
How The Universe Was Created.
There are many opinions going around, but I myself believe that the Holy Spirit God created it. I believe that God said it was there and then whatever he said showed up, because he is just that holy and powerful. It wasn’t just some long drawn out process that that took the particles of an explosion to travel through the galaxy, It was a seven day process that took God seven days to make perfect.
What Really Happens in a Chemical Reaction?
Every chemical reaction starts with one or more reactants. Atoms, molecules or free electrons can participate. They combine, swap atoms or decompose into the reaction’s products. If a reactant is a single atom, it’s usually in ionized form—having too many or too few electrons. Molecules may be neutral or ionized. The reactants must be in physical contact in order to react. This usually means they occupy the same container and are being heated or mixed together.
Lab Safety and Lab Equipment
There is a reason the teachers want you to know about lab safety, and the lab equipment. It is very dangerous to taste or smell some substance that you are not familiar with, because you could be burned or get bad chemicals in your system that are unhealthy for your body to take in. It is important to know about your lab equipment because if you you think a hot plate is a digital balance you will get seriously burned.You shouldn’t wear opened toed shoes because they are a target to chemicals or shattering glass.
