3 Ques. Blog 11/24

1)The tasks I have completed were finding if reactivity of an element shows a periodic property.
2)I have learned how to find a certain element from its groups, column, and families.
3)I plan on noting it better so I can find the valance and groups and such much faster. In a way I can remember better.

1) The question we were trying to answer was do average masses of different beans really equal a standard quantity? 2)What we did for our investigation was we got 50 beans of each type of bean and than we scaled them, finding out which one weigh less in which we use that one to get our relative mass for the beans. We did it like this way so we can see if they could equal the standard quantity of the beans. 3)Our claim was yes, because the bean count was equal to it's relative mass. Our evidence is the picture below, which shows the bean type, mass, relative mass, and bean count. Our reasoning comes in 3 parts,  for the first part was why we choose yes, because the bean count all fell around the '20' amount. Rather then random numbers. On the second part for what the relative mass means, is was the relative mass will be the bean w/the smallest mass which, will be the bean all are compared to(each type of bean) example: lint bean/ kidney bean. And the last part for how this

1)The question we were trying to answer if  reactivity is a periodic property . 2)What we did for our investigation is we got certain elements and put them in regular water to see the reaction. Since water is very simple, it made sense to put the elements in it to watch the results. 3)My claim was 'Yes, reactivity is a periodic property.' My evidence was what the element was, and what we matched what happend when it touched the water. (Highest Reactivity to Low) ----Potassium | It generated a pink flame and fizzed and moved around. ----Sodium | Fizzed and spinned around. ----Calcium | Bubbled and fizzed. ----Magnesium | Nothing when in water and turned pink when heated. ----Copper | Nothing even when heated My reasoning was 'Potassium was more reactive than Sodium, because Potassium caught on fire and Sodium did not. Then Calcium didn't moved around but fizzed like Sodium. Then Magnesium had nothing to do with the water by itself intill put in heat, and Copper
