Exploring atomic structure & electromagnetic radiation EXPLORE LAB WRITE UP 10/27/17

The question we were trying to answer was “what are the identities of the unknown solutions”?
During this investigation we completed our pre lab write up & made a chart in our notebooks. The chart had two sections one for the consumables ( calcium, barium, copper, lithium, potassium, sodium, strontium, and four unknown) and the other was for the  color of each consumable. Then we lit our busen burner after that we went up to Ms. Gardner and got 2 matches at a time with the metals on them. Then we put each match one by one under the small blue flame in the middle. We then observed each color of each metal and copied our observations of each color into our table. We conducted our expirement this way because we felt it would be the easiest and most organized way to see and compare our data. Our claim is that unknown one is sodium (orange), unknown two is barium  (yellow/green), unknown three is lithium (red), and unknown four is potassium (light orange). In this lab the flame test works because as the electron goes up and gets excited it goes out into the unstable and comes back down to ground state and emitts light (energy) and the same light it absorbed.

3 Question blog #2 (September 15, 2017)

Recently we have completed a " Chemical vs. Physical properties and changes lab". This lab consisted of 10 different experiments. The first experiment consisted of a bunsuen burner and matches, each person in the group took a turn lighting the Bunsen burner. The second experiment consisted of Alka seltzer tablets, a graduated cylinder, a stopwatch and water. At this station we put the tablets in the water and observed what happened as well as answered questions. The third experiment consisted of cobalt II chloride, sodium phosphate, a small test tube, and empty beaker and a waste beaker. With these materials we first placed the test tube in the small empty beaker, then we transferred five drops of cobalt II chloride solution into the test tube. Then we answered a few observational questions and following those questions we added 5 drops of sodium phosphate in the test tube. We then answered more questions and cleaned up our station. Next was experiment four, at this station w

3 Question blog #4 (October 13, 2017)

Within the last two weeks we have completed an Atom PHET sim packet, as well as exploring isotopes and average atomic mass lab. What I have recently learned is that the atomic mass of an element is the weighted average of the masses of the isotopes of that element. I plan on improving my understanding by actually learning the PHET packet materials as I go rather than just fill out the packet.

During this lab exercise we were trying to discover whether each bag of Cheetos had the same mass, and if the buyers (us) were  getting what they payed for. We first began the lab by gathering four bags of cheetos and labeling them one through four. We then weighed each bag of cheetos with the content inside (one bag at a time) on a scale. Each weight was recorded onto a table, this first weight was called the "Gross weight" meaning that this was the initial weight of the unopened bags with the amount of cheetos it came with. We then emptied the content of each bag onto a paper towel, followed by taking the Empty bags back with us back to the scale. Once again we weighed each back individually and recorded the weight onto the table. This time there was nothing in the bags and this weight was called the "Tare weight" meaning the weight of the bag with out the cheetos. The next step we took was to accumulate our "Net Weight" which was the amount of "Ta
