Human Anatomy-Eyes and Ears

 It's been a while since I've been able to update this blog but we have been carrying on with our human anatomy study.  We started off with the ear.  L decided she didn't want to make a model of the ear this time so instead we watched some Youtube videos on how the ear works and it's parts and then she coloured in the diagram pictured below.  We did a fun experiment to see how the ear drum works.

L covered a bowl with cling film to represent the ear drum and put a few grains of rice on the top.  She then banged loudly on a cookie sheet with a wooden spoon.  It was cool to see the grains of rice jump up and down as she banged the sheet.  This represented how sound causes the ear drum to vibrate which then sends messages to your brain about what you are hearing.

Next up the eye.  After looking at some diagrams and watching a Youtube video on the eye L made this super cool model of an eye.  I cut a ping pong ball in half and cut a small circle in both sides.

L added all of the parts using different household items.  We actually used wool to needle felt the iris as well.  L used sticky notes to label all of the parts which was quite a challenge as the model was so tiny!  She even added eyelashes and lids using electrical tape.

After making the model we did the fun experiments from this site .  It was so neat to find our blind spot and figure out which of our eyes were dominant.
