Frog and humans
by: krishan12345


The frog is a great specimen. My experience with Joe ( the frog) was very exciting. I learned that the frog was a lot like humans. The digestive system start in the stomach instead of the mouth. Also I learned that the stomach starts chemical and mechanical digestion. Then afterward that food goes to the small intestine to be absorbed. Lastly I learned that the liver was that largest organ in both organ systems.

Something frog that I found interesting was that the liver was the largest organs in both organ systems. I also found that all the eggs in the female frog which were a lot. The eggs was like a protection, that how may there were. Thirdly I found that the frog had two layers of skin and muscles. When I first cut into the frog I found surprising I had to cut two layer to get to the real organs. Lastly the frog  dissection was very educational and taught me so much of my body.

Our Stomach

Science class we learned about the stomach and how it works. There are enzymes in your stomach that help hydrochloric acid. The acid destroys food and allows the organs to use the energy and vitamins from the food. The stomach is lined with mucus which doesn’t allow the acid to eat through the stomach. We did a lab in class that shows the acid and enzymes work. When the acid was alone it didn’t work so well, and neither did the enzymes. The enzymes were mixed with the water it started to decompose but the acid and enzymes worked a lot better. We also saw a video and that me understand a lot better. Without hydrochloric acids and the enzymes we would die because we wouldn’t have enough nutrients.

The Great Chicken Wing

In science we saw and video and in person a chicken wing dissection. My teacher took a meaty chicken wing. We saw the skin which is an epithelial tissue. The epithelial tissue is a type of tissue that protects the rest of the body. An example would be the skin. Below the skin we saw the muscle. The muscle tissue is what makes our body move. The muscle is pink, smooth and is connected to the connective tissue. The connective tissue is our bones. The ribs, femur, fibula, and the foot bones are all connective tissue. Inside the bones there is blood which also connective tissue. Inside the bone we can see the bone marrow. This is how the chicken made blood. The last was the nerve tissue. The nerve tissue cannot be seen in the chicken wing but it was there. That is all four types of tissue: epithelial, muscle, nerve, and connective tissues.

Science Diffusion Conclusion

In science there was a lab that I explained already below. This is the conclusion of the lab. The purpose of the lab was to see how the cell works in an animal. The solution in the bag was corn starch; in a beaker was diffusion iodine. The iodine was in water which lowered the concentration. The bag was permeable, and the corn starch could not come out. The corn starch or carbohydrates was white, and the solution was brown. Osmosis is the change of concentration in a solution when you add water or take away water. The hypertonic iodine which means that it was more concentrated, leaked through the bag and changed the color of the corn starch, which is less concentrated or hypotonic, changes color when it revealed by the indicator, the iodine. The iodine is more concentrated then the corn starch but it is still less concentrated the original iodine. What happen was that when water was added to the iodine is lowered the concentrated, this process is called dilution. The prediction of it staying white was incorrect.
During this lab the class had many implications. The implications of the lab were to figure the ways how the permeable bag is like a cell and to see how it lets the iodine in but doesn’t let the corn starch go anywhere. In the beginning, the class took about two spoons fills and put it the the permeable bag. Later, the class poured 500 ml in a beaker. Iodine was added which lower the concentration. The bag was put in the beaker. After 15 minutes the class did analyses on the bag. The color had changed.
There are many examples of diffusion. One example is a campfire. If there was a campfire the the smoke would spread a wide amount of area. Another example of diffusion is when somebody is baking cookies; the smell of the cookies fills the house. A third reason is when a person is smoking a cigarette the smell and puff of smoke hovers around the person. Last but not least is the way ink spreads in a cup of water. Let’s say there a cup of water and you drop ink in the cup. The ink spreads around and changes the color of the water in the cup.

Diffusion lab

In Science we tried to see how the membranes work in a cell. When they’re a corn starch in a bag and preamble bag, we put the bag in a beaker with iodine. Iodine will detect sugar, cornstarch, and will turn it into a purple color. At first nothing happened but after 15 the corn starch in the bag changed color. It was brown and dark brown, meaning that the iodine had reached the cornstarch. This is similar to a cell membrane when it decides what stays in and what stays out. The bag being the membrane and the sugar in the bag being the organelles shows how the membrane works. The lab was exciting, and fun. (Caution the iodine is poisonous if it touches the eye or if drank. can be found in stores such as target)

New Jersey Solar ?

What would you do if you have hundreds of dollars saved every month after you install solar panels on your roof? The state of New Jersey has the highest 19 cents/kWh compared to 11 cents. In the USA we can harness the sun electromagnetic rays to give off less pollution in the world. The waves that the sun give off is electromagnetic, and the solar panels change the rays into electricity. The sun's rays travel in waves. The waves are energy and can help the earth tremendously. In science we have been learning about it but, the little knowledge can help. The sun's rays are sent through mediums and then hit our solar panels.The energy doesn't disappears but it turns into electricity and can be used for the lights in the house. switch to solar panels and save hundreds on you electricity bill.

Science Project

In science we are making a Gravity-Powered car. The car has to be able to go down a ramp and not fall apart, though it will go through many tests. My car is made out of recyclable boxes and a wood perimeter to make the car doesn't fall apart if it crashes. The car is due on the 25th but there is extra credit for those who hand it in by the 20th. The car wheels are old rollerskating wheels that are no longer needed. The car is going to be the best car in the class, and hopefully the fastest. The car experiment is going to be fun and a learning environment.

Soaring Straws

                  Gravitational Potential Energy (G.P.E.) is related to Elastic Potential Energy(E.P.E.). The only way E.P.E is more related to G.P.E. is the more the E.P.E. the more G.P.E. When the amount of stretch was only 3cm the average height was 1.7m. as soon as the amount of stretch changed from 3cm to 1cm the average was .98m. Therefore E.P.E s equals G.P.E.

                 Even though the tests were done in the same enviroment, the rubber band that we used broke. Hence the new rubberband may have been stronger or weaker. Also when we, my partner and I, shot the rocket up we were off by 5 or 6 cm.Thirdly, we couldn't see if the stretch was 5 or 6 .This lab should have been done outside or inside on the staircase. The lab Soaring Straws was fun and understandable.

The Science Lab

There are many a fish in a lake or a, but the question is what happens to them. To science we are doing a lab that talk about the way the fish reproduce. The lab starts with 8 toothpicks with three different alleles, yellow, red, green. Yellow and red are recessive to green and combined equal orange. Each fish has two alleles one from the father and one from the mother. The first generation I picked 6 green fish1 red and 5 orange. The second generation was the same thing. The third had a change in the pattern, there are 3 yellow, 5 green, 3 red and 0 orange. This terrible because this was all of yellow fish died because of the non-camouflage. As a result only nine fishes were left. The fourth generation was terrible because a company and spilled toxic waste in to the pond/lake that the algae had died therefore showing all of the rock and the green fish have no camouflage. Only leaving the red and yellow and orange left and the green alleles were wiped-out.

            If I had changed the lab I little bit it would be about the alleles for the fish that started, such as I would have co-dominant alleles instead of having incomplete dominant three alleles. Also I would have change the color yellow to a darker color to blend in with the dark lake below it. With the change I have made with the colors changing to blue, red, and green, blue and red could have made a purple or a blue top and a red bottom, much like a penguin. Next change would be to have two dominant alleles instead of one. The two dominant would have made it harder for the recessive and the dominant would have to fight it out to see which one had to be shown. In conclusion those are the change I would make to the fish project.

The Amazing Science Class

In my Science class we have been learning about alleles and incomplete dominance and co-dominance. Even though they sound the same they are totally different thing. Co-dominance the alleles keep fighting to be shown. Let’s say the alleles are white and red. The possibility can be red with white Polk-a-dots. Incomplete dominance is if red and white are alleles than it would be pink because the alleles are like compromising. It’s hard to understand but, after I while it is easier to understand. Also we are doing lab that is all about fish and offspring alleles. The project is in pairs and very fun, but we have to write 2 paragraphs. I love the class and don’t have any negative comment and the monster project is extremely fun. I feel a great joy going to my science class and always going to the class.

In science class we've been working on punnet square. The punnet square are fun they show the difference in alles in a genes. My friend and I good at the punnet squares, and have been finishing them fast. I feel that we should have been taught how to do the 16 squares before giving us the sheets. The Spongebob worksheet was fun and interesting. The idea cartoon worksheets gets ride of the boringness of worksheets.

The cell quiz was nice, but the cell quiz should have been more parts. Also the cell quiz should have I place for labeling, and it was too easy. The quiz was easy that I passed with only the 3 minute in class to study. Also there was two glithes in the quiz that I spotted. The two question that didn't go in the matching part were lowercase.In the end science class is fun and interesting. The quiz was easy and the punnet squares should have been explained.
