Last week we found out about Skeletons. This week we discovered that muscles are needed to move them. We discussed how muscles are used every time we move. Muscles are attached to the bone by tendons and work in pairs to allow for smooth movement. To move a joint, one muscle contracts while the other muscle relaxes and becomes long. Did you know there are more than 600 muscles in the human body? We conducted an investigation to see if people with longer forearms/longer muscles had faster reaction times when catching a test strip. We used our measuring skills, made predictions and recorded our findings.
This week we found out about the three main functions of the human endoskeleton - to protect, to support, and to allow movement. We discovered the names and locations of major bones, including the skull, jaw, spine, pelvis and femur. We worked in groups initially and traced around a group member. We then drew the bones we knew and then found out about the scientific terminology for a variety of bones and labelled these on a human skeleton diagram.
This week we have thought a lot about nutrition and the various food groups. We studied food labelling, designed a healthy well balanced meal and made food from the various food groups to form part of a classroom display.
