Matter Report

During the past few weeks we have been learning the four states of matter, liquid, solid, gas and plasma. During these few weeks we tested several labs to observe changes in the matter. We did the candle lab, the marshmallow lab, and the sugar cube lab. During the candle lab we had two candles, a thick white candle and a green birthday candle. We needed to observe details, use our senses, and follow directions... just like the marshmallow lab and sugar cube lab. We needed to feel the candle before we lit it and after we lit it we needed to observe. Then we mixed vinegar and baking soda to get carbon dioxide, which does not support burning. This gas put out the big candles flame. During the marshmallow lab, we had to observe, rip, and taste a small marshmallow. Then we needed to attach a larger marshmallow to a stick and burn it. After that marshmallow was burnt we needed to taste the burnt part. During the sugar cube lab, we needed to observe the sugar cube. We then tasted it, mashed it up, observed it again, placed the crushed sugar in water, tasted the water, then put sugar in a test tube and held it over the Bunsen burner until orange smoke came out. We then let it cool once it turned a dark orange or brown color. We tasted it and made our observations. During all three labs we saw chemical and physical changes happen. We learned how to correctly follow directions and make detailed observations to get an interesting outcome to all three labs. In the future these labs will help us notice the physical and chemical changes of matter whether it is liquid, solid, gas or plasma. We will become more observant and knowledgeable to the matters surrounding us.

Mystery Cup Procedure

Procedure:

1. First take the filter paper and put it around the circumference of the funnel that was given. This will drain the water from all the objects mixed in the cup and separate from them.
2. Then take out the obvious objects like the toothpicks, flat marble, as well as the beans.
3. Next put the blue provided magnet into the plastic cup, now only containing a black subject and sand. When the magnet is placed in the cup… the black subject will attach to it.
4. Then figure out what the black subject is.
5. Next pour all the water from the graduated cylinder that was recently separated and move it into the graduated beaker.
6. Remove 75% of the water from the beaker and place it into the Erlenmeyer flask.
7. Then move the flask to the hot plate. Turn the dial to a medium heat setting.
8. Watch as the water evaporates and take the beaker off when no water is left in the beaker leaving only a mysterious substance.
9. Take some of the disfigured substance out… figure out what it is then write a list of what was found.

Education IS the Key

“Education is the key to unlock the golden door of freedom”
-George Washington Carver
To me this quote said by George Washington Carver is truthful. Also to me knowledge chooses the path of life and that leads to your future. So education can give you that option and freedom for your own different future. Each future is unique and can be special with a good education. Education CAN OPEN all the door needed for you to choose your future. So having a good education or the ambition for that key... the door will open soon. The opportunity is there but you need to work hard to seek the reward that key will provide. The key to success is there to look for... on the other side of the golden door is the right path if you decide to open that door.

The Frog Dissection Review

Last week during science class... we dissected a frog! Monday we learned about what we should look for while dissecting. The things we need to look for were the systems and its organs. The next few days we got to go hands on. We used certain tools to open the the frog by cutting up the middle and between the arms and legs. You needed to be gentle yet firm to cut through the epithelial tissue and muscle. Once you open the flaps and pin them down, you will see if the frog is male or female. The females contain eggs and oviducts while the males contain testis. Once any unnecessary parts inside the frogs are cleared from the body so the main organs are visible such as fat bodies... we identify the organs. The first thing I saw was the liver because it is the largest organ in the frog and is composed of three parts or lobes. Covering the organs are the peritoneum which is a spider like membrane that covers most organs. At the top of the liver their is a triangular organ called the heart. Under the heart are two raisin looking organs called lungs. Near the liver is a green sac which stores bile. This organ is the gall bladder. An organ curving underneath the liver is the stomach which is the first major site of chemical digestions. I learned that frogs swallow their meals whole which after it goes through the stomach it goes to the next part of the digestive system. The small intestine as well as the large intestine just like the human body and exits the same way. The last few organs we were instructed to look for are the spleen and esophagus. The spleen is a dark red spherical object that is the holding area for blood. You would think it was gross... but your wrong!

At the beginning of the dissection I did not think I would enjoy it. It was so cool and interesting. The odor once you walk into the room is overwhelming and scared me a little because I did not expect it... especially after lunch. Once we were given our tables and partners it was go time. We listened to the teachers instructions. Then we tied any hair back and placed our goggles on. We examined the OUTSIDE of our frog then proceeded to open the frog. We were gentle but not firm and only cut through the epithelial tissue so we had to cut a second time trough the muscle. I was in awe when I looked in and saw it was a girl. Our group decided to name the frog Lily. We loved looking at the organs and finding where to find them in the frog. At the end of the week my favorite part was opening some of the organs to see the different textures. I loved this dissection and can't wait to do more!
