Liam’s Science Journal
Right at the beggining of the year we were given a document called, science journal. The first assignment we were given was to write in our science journal about the consumers and producers of the food that we eat. We named three foods from our weekend and then wrote about them. The second project we did involved us reading an article that we were sent. In it, it showed a few ways to help our city cultivate new organisms and plants. We wrote these ideas in our blog and added some new ideas to it. I have really like our science journal because we usually have time to do it because it is homework and it seems to be a very different assignment every time.
Structure Fits Function
Structure fits function
5 types of joint: Condyloid, Saddle joint, hinge joint, ball and socket, hinge joint, pivot joint.
The joint are the connecting points between the muscles and the bones. There are 5 different types of general joints. The ball and socket joint is made to almost move on a 360 degree angle. There are a lot of ligaments because of how much movement it can do but since there are so many ligaments a lot of things can go on. The ball and socket joint structure is good because when protecting or blocking yourself human instincts are to cover yourself with your arms using your ball and socket joint. You have to move your arms in many directions so the ball and socket joint is very useful.
Hinge joint:
You will find this joint in your fingers. This joint only moves one way. It is just like door.It only moves forward. Our human body has adapted to picking up things so now our hands only need to one way, but who know what we would be capable of if we could move our joints backward. Where would your nails be. Our life would be very different if our fingers were more like the ball and socket joint. The animals before were digging so this joint was an advantage. It would make your joints stronger.
Condyloid: A good example of the condolid is the wrist bone. The condyloid is what gives the wrist bone flexibility to move in different ways. But it doesn’t get all of the flexibility that the ball and socket gets.
Saddle joint: You can find this joint in your thumb. The thumb sits on a kind of bone that sits on another bone. The saddle joint is also what gives your thumb to move in different ways, like how you can touch all your fingers on your hand with only your thumb.
Pivot joint: The pivot joint you find in your elbow and that makes you rotate your elbow in different ways.
6th grade science food intake
IN science we started studying the human body. We looked at what food is good and bad for you and then we estimated how much protein, grain, dairy, fruit, and vegetables we ate before we started this project and then we recorded how much of each food we eat now and this is the chart. To see the chart click blog post in the image.
