Ingredients of the Melting Pot When reflecting on a timeline of America‚ what is clear is that this nation has grown in many ways due to far-reaching ideas‚ movements‚ and historical events. Immigrants who decided to continue their lives in the United States remain as the key factor of keeping this country functioning at the prosperous rate that it is. Unfortunately‚ Immigration has always been a controversial matter in America. Nonetheless‚ the population of the United States’ composes of citizens

My SRP is determining if the colour of ice affects its melting rate. Ice melts by taking in energy from its surroundings to form heat. This makes the molecules in the ice cube vibrate. As the overall vibration increases‚ the water molecules split from each other turning the ice from a frozen state to a liquid state. Heat can be absorbs in two different ways‚ through direct contact with a hot surface or through radiation of a hot surface nearby. Radiant heat can be contributed by sunlight‚ fires and

After performing this experiment‚ it was found that the surface the chocolate was placed on could make a major difference. The hypothesis that was made had mostly incorrect predictions‚ but with some correct ones. It was found that using the palm of one’s hand was the best surface on which to melt chocolate‚ as was predicted. It melted so far‚ and so fast‚ that the experiment had to be altered. Coming in second place was the surface of black paper‚ something that was not expected. The black

lObjective This experiment explores how salt and sugar affect the melting rate of ice in water. Research Questions: * Does adding salt to ice and water slow down‚ speed up‚ or not change the rate the ice melts in the water? * Is salt the only substance to have this effect? What about sugar? Knowing how to speed up the melting rate of ice is very important information for anyone who needs to de-ice roads or driveways after a winter storm. While it seems simple‚ adding salt to ice water

occurs in everyone’s life. When we are born there will be a time when we are no longer young as we used to be before‚ but in fact we will start to age as the years go by. This can affect how we react to certain things and how quickly we respond. People who are older have nerve impulses that react more slowly and will have a slower reaction time than people who are younger. I think that as we grow older our reaction time does decrease.

ice is slowly melting‚ so that also means our glaciers are melting (shrinking). This is a problem worldwide. The oil‚ coal‚ natural gases‚ and fossil fuels we burn affect our atmosphere and increase the temperatures that melt our glaciers. If the glaciers continue to melt rapidly ocean levels will rise‚ there will be flooding‚ there also could be droughts. This is a very serious issue today but I’m just going to tell you about two places for now. How does the melting of glaciers affect people? Here’s

summary The reaction time test that had taken place involved the students to sit at a laptop and press the go button on the screen with their touch pad and wait for the stimulus to appear on the screen. When this stimulus would appear the student would then have to press on their touchpad with their writing hand and the amount of time that it took for the student to react to the stimulus and press the touchpad was the reaction time that was timed. The test was taken 3 times and the average of that

Jared Choy Mr. Dahlhausen Period 6 17 November 2014 Does Age affect Reaction Time? When a person sees a health care provider and the doctor hits the person’s knee with a rubber mallet‚ the person’s leg kicks up on its own. This happens because when the doctor hits your kneecap‚ the tendon under it gets stretched‚ which in turn will send a signal to an awaiting motor neuron so it can command the muscle to contract. Let’s take for example the reflex arc. A reflex is the involuntary movement of the
