Dr Terry's Visit

 Today my class and I had genomics so we had a visiter and his name is Dr Terry or Mr Terry. He is a scientist and a very well experienced one. He came in today to talk about cells and how to use a scope. He showed us a photo that was about tissues, cell and DNA which stands for deoxyribonucleic acid. He explains what cells do and what cells are made of and after explaining he showed us how to use a scope that are very expensive and are used in university. He explained how to use it and gave us slides to see what we are looking at. After seeing tiny creatures in a scope we got the chance to see a small bug that is called lice. I could see the segments and the tiny hairs on the legs. After seeing all of that and learning about cells Dr Terry had no choice but to leave for a meeting because he is very busy, but at least he gave the opportunity to save his time and teach us all these new and interesting things. After saying goodbye and thank you to Dr Terry he left and hopefully come back next week.

How Our Ear Works.

 

Today at school my class and I decided to make a animation out of slides. And it was about our ear and how it works,The way our ear works is it goes in our pinna and which catches vibrations of the sound, the pinna is made out of cartilage and after the sound goes through the pinna it goes into the auditory canal that has wax that protects your ear from bugs,dirt and water then it goes to your eardrum (tympanum science word for eardrum). The eardrum is a thin layer of skin that catches the vibrations and goes to the cochlea. The cochlea turns the vibrations into electrical impulses that go to your nerve and to your brain.

Technology Hard Materials

 Today at technology my class and I went to tamaki college to do the rest of our pewter casting work on how to build a necklace by melting the metal and pouring it into a mold that we made with a small wooden platform that's called MDF. After pouring the melted metal into the mold and letting it cool down we would start to try and finish of our work on a doc that Mr grundy our teacher sent to us to do. I already done all of it so I am on the part were I have to use a certain sandpaper to help smooth and soften the sides and the edges of the pewter necklace. On each sandpaper there's a number that helps to identify which sandpaper it is because every sandpaper is different. So the first sandpaper I had to use was the number 180, I started using it to scrub the bits that were not as smooth and not as soft as the other. After done I started to use 400 and 1200 and started to scrub the edges and sides, I then repeatedly did it over and over again.
