With the knife, carefully cut a 1 cm (3/4 in) slit into the lemon about 1/3 of the way from the other end. Insert a copper coin into the slit so that about half of the coin is inside the lemon.

Learning Styles

...enjoy classical music or instrumental. It is soothing, relaxing and I need to be calm while trying to focus. I don’t always need music to study there are times when it just helps when redoing notes, but not while trying to read information to be retained. My second style was Naturalistic. I enjoy the outdoors or at least an outdoor setting inside if possible. I have moved my desk next to a window with plants hanging as well as sitting around my desk. I allow my pets to join me in the room, but I pet them and sit them down on their pillow or close to my feet. I enjoy the natural lighting from the window instead of the harsh desk lamp at night. The breeze that blows through the window is relaxing to me. I keep a diffuser of lemon oil going most of the time, lemon smell makes me happy and peaceful. I tried to set up my area that makes me comfortable since I knew Nursing School would require me to sit and study away from distractions at home. While spending a lot of time in that space I wanted to make it appealing to me, not dreading to be there. I hope that this will put me in the right frame of mind while studying and help me relax, retain information and learn. My last style was Visual. I chose this category style even though I scored the same as Body and Verbal. I believe this is an area I need to focus on more for school.
