with acetic acid to produce a short amount of electricity. Even though it only conducts a small amount of voltage‚ we investigated and experimented on how it can produce more than usual without adding any other components on the project except zinc‚ copper‚ vinegar‚ or a unique container that can increase the voltage of our product. The zinc can produce electricity because of the chemical reaction it occurs when it is soaked in vinegar’s acetic acid‚ the zinc is dissolved to produce hydrogen gas; while

Research Activity Constructivism and Student Misconceptions: Why Every Teacher Needs to Know About Them The article I chose to do this research activity on was "Constructivism and Student Misconceptions: Why Every Teacher Needs to Know About Them" by Audrey Sewell (Appendix A). I believe this article addresses a key idea that all teachers should be aware of‚ student misconceptions. For this paper I will start by summarizing the key ideas‚ then I will go on to discuss how they relate to the

In this paper‚ big history will be explored through the formation of the current U.S. one cent coin or more commonly referred to as a penny. The big bang theory is a scientific origin story‚ based on real evidence which explores history in thresholds from the big bang to present. Thresholds are time periods that break up history into sections and each one is marked by significant pivotal

There are 18 data sets that accompany the text book. These data sets can be found when you enter StatCrunch from the course. Here is a list of the data sets and the variables found in those data sets. If there is no listing of variables then they are easily identified in the data set. Data Set 1: Health Exam Results (both male and female) AGE is in years‚ HT is height (inches)‚ WT is weight (pounds)‚ WAIST is circumference (cm)‚ PULSE is pulse rate (beats per minute)‚ SYS is systolic blood pressure

For gold coins‚ soaking in very hot soapy water works the best. For old pennies‚ soak the coin in vinegar for at least 24 hours. For bronze coins — usually ancient coins — soak in distilled water (the minerals in tap water can further taint the coin’s surface if soaking for a long time) or olive oil — olive oil is a very gentle way to clean coins‚ but you may need to soak them for several weeks. Silver‚ copper‚ and nickel-clad coins can be soaked in distilled water or‚ to remove tough

A penny has almost no value yet if we can find value in something so small we will be rich indeed "But if you cultivate a healthy poverty and simplicity‚ so that finding a penny will literally make your day‚ then‚ since the world is in fact planted in pennies‚ you have with

My four liquids will be vinegar‚ beach‚ lemon water and salt water. To get started‚ the metal contents should be established.
