Poison ivy

Poison ivy leaf that has three shinny leaves that have oils on them and when you brush the leaves the oil will get on your skin. Also poison ivy takes a few hours to get into your skin so you can wash it within a few hours you will not get full effects. Also poison ivy in not meant to harm people it is poisonous so animals do not eat the leaves. Three things that I learned is that a remedy to stop the itching of poison ivy is to take a hot shower as hot as you can stand. Also the itching form the poison is pain inside the nerves and how they react to it. Itching your skin for a long time or for several weeks can start to damage you skin.

Ryan, Pretty basic but OK. Looks like you did learn a few things. I thought the shower idea was interesting! 5 stars. MW

Discussion of oil

Hydrocarbons are separates by the process of discussion. The separation is allowed because of the different boiling points. Fractional distillation is when the different hydrocarbons condense in the tubes because of the different condensing points. Industrial systems heat the hydrocarbons. The different melting points have different condensing points for it to collect. The large, high boiling, molecules are left on the bottom where it is hotter. The lower boiling points raise the top and collect at the top where they cool. This is very interesting to me because I never know how the oil was made into gasoline. Also I knew that oil could be made heated and separated into so many useful things.

Ryan OK. Decent summary. 5 stars. MW

Motion Detectors

Three things that I know about motion detectors are that places of business use them sometimes over night to watch for robbers. Another thing is I think that the motion detectors work off of the inferred radiation that all humans give off. Another thing is that motion detectors are a way to save energy by turning the lights out if you left the room. I learned that the safety features of my garage door are set by motion detectors. another cool thing that i learned is that a snakes eyes are like a motion detector at the grocery stores and they can see warm blooded animals. I also learned that with most motion detectors glass will stop the detectors from working so people outside of the store will not open the door.

Ryan,

OK. Watch your sentence structure. 5 stars. MW
