Exploring changes in matter blog

1)What question were you trying to answer and Why?
- The guiding question for our lab was which changes are examples of physical and chemical changes? My team and I were trying to determine out of the 5 examples we were given to experiment on we had to figure which was an example of a physical or chemical change.

2) what did you do during your investigation and why did you conduct your investigation in this way?
- I helped set up the Bunsen burner and was in charge of recording the data from each experiment we performed on while two of my lab mates got the materials ready and did the other examples. We did it thus way so we could get done faster and be more efficient.

3) what is your claim, evidence, and reasoning?
- are claim was examples of chemical changes are heating copper wire, mixing sodium hydroxide and copper 2 nitrate, and hydrochloric acid with sodium bicarbonate. The evidence for the chemical change was because it produced something that wasn't there before and it was a physical change because nothing new happened.

Reactivity and periodicity explore lab 1.) Our guiding question was: is reactivity a periodic property? we were trying to observe how each element would react differently when exposed the same thing. 2.) I helped with the beakers, getting the elements, and graphing the data. each on of my group members had different thing's to do so we could try the experiment in a more fluid manner 3.) Our claim was reactivity is a periodic property, our evidence when we observed the metals was that sodium moved and bounced around the tube and dissolved in the DI water and made a fuzzing sound, magnesium floated to the top and the metal turned pink the strip had bubbles, potassium there was a flame it sparked loud and smoke came out of the beamer, copper had no reaction, calcium it fizzed producing a spiral like bubble and it was hot to the touch

Exploring isotopic and abundance lab 1.) The question me and my group were trying to answer was how much atomic mass was in beanium 2.) All i did was observe and record the data and find out the atomic average and mass for each bean and this was to differentiate and determine how we find the abundance 3.) Our claim was that the atomic mass for beaniu m was 0.43, we made a chart to justify our evidence and our reasoning was the average mass of beans and percentage were needed to get the beans mass by itself because the beans are not the same
