6. Overall Experience
I think we need to work more understanding because some of them I was not understanding much. So I think we need more time understanding more than get to the imagine an plan to go to prototype. It is very important to understand because you understand how to make your catapult.
I think I would get a D because first I was not understanding much at the first time doing the force and motion. I was not understanding potential energy and kinetic. They were hard for me first time but later and later I'm better so I would got a D.
I think we should design because we still have some problem and we want to fix it so we could test it to see the mistake again, a fail help me one step to improve and I want to fail to improve, not win right away. I could know more about the problem with my catapult,also I would make it lower and not too high, our third one we add the stick at the back to bend it to there and we have lower a bit, the stick at the back would make the arm not stored too much potential energy.

Prototype 13. Prototype
I think I change about 2 times, first time we make our first catapult without knowing anything, Ms.Hannah want to see our background knowledge. Second is when we test and then we lower and decrease the power of it and also that time was the last day we play with catapult.
When we do the highest and the most strongest because we have the most sucessful that time and everybody say it was so awesome. We also think that was also great. Sucessful but fail in the test, still that is our lesson to know how to fix so that was the most sucessful change that Jackie and I made.
Prototype 1Prototype 2Prototype 3 This is the video that we test our catapult. It was too high and too strong. That is our second prototype. It fly too high and strong so also that time we fix it. Still our class have lots of fun in the test.
4. Validate
Explain ONE change you made to your original and write your validation here.
I change to make the part I put the arm so it wouldn't fly too strong in my change and my validation are here: Which forces are present? Potential Energy, Kinetic Use potential energy when we pull the spoon back the potential energy is stored and when we put out the kinetic is used when flung 2. Imagine/Plan
First because we have to imagine how would it shoot and we have to plan how should we build it because if we didn't plan or imagine we cannot build it, it would be bad. Also the building would be different when we think because we didn't imagine or plan about it. It helps us to make the catapult a lot.
It did not work because we make my one higher than that but it still work for me and Jackie because we made it fly over the chair and I'm very happy about that. The thing that didn't work are it fly too high and strong so we are decreasing the power down.
1. Understand
I was understanding that my prototype shoot to strong so we have to lower the force because last time it hit the glass and fall down so I have to make it lower and have less force. I also understand that my catapult that the base is strong so it can balanced on the ground not like last time.
1. How did you feel about the technology involved? Do you want to use screen casts again in the future?
Yes I want to but when we screencast sometime the voices get really small and a bit of crazy sound. Also it is very lag so next time if I screencast I would use another program. Still it is a great screencast and I’m proud of myself. I was involved on this because I know more about the screencast thing first I don’t even know what screencast is and now I know it. 2. What do you think about your video? What part are you most proud of? Which part do you wish to improve? I think I want to improve on the voice and be more confident because that time I was very nervous and also I was talking very small. I think it is not a good video because it was lagging and also crazy sound and I think it is not a good video so I just think that. Still I was proud when I of myself when I record because it is the best screencast I ever although it is not good than other YouTube Recorder. My other screencast was not good this time it was not good to but still I think it is the best screencast already. 3. Is there anything you want to say about your experience in this community that you did not get to say in your video? I think the community was great and also I think when you die. You can just wait that day and next day you get to play so that everybody can enjoy and be happy. Also the community will work well if we do more than that and we have more time to play so that we can learn more and get to play more! Today is 2nd of Puberty Talk. I learn a lot. During puberty you can have spurt it mean that you will grow taller but only when you sleep. Later when you wake up you sored your feet and back. When you grow hair you, you will have oil but sometime you have too much and you will had zits. Do you know that hairs are in all of our body that we just only don't feel or see it. It is very tiny. We have learn lots too. We also learn how baby form. You grow during puberty by hormonoes.
Today we were learning a little about puberty, we learn the reproductive system, in boys they have a line where it keeps the sperm and boys have a penis to pee. Also boy have a bladder and a bladder is a thing that hold your pee. In female they have a ovacle which hold their eggs and in 8 to 19 years old you will have a thing called periods when you have a eggs in your body and it will bleed. It is a little bit painful. It takes 28 days and it is about a month. They also have a uterus which for woman who have pregnant their baby is on the uterus. There is a thing called vagina which lay the baby out. Also girls grow first boy but the girls don't grow longer than boy so thats why sometimes boys are taller than girl. Everybody will have puberty that is not a choice or not it is a choice and you have to do it.
