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 wo

3 Question Blog October 27, 2017

During the last two weeks we have competed and electron energy and light pogil. As well as a hope it floats practice and two flipped notes on unit 3. We also completed a flame test lab in class as well as a  light practice worksheet. I have recently learned that the colors are what makes the electrons unique. The energy absorbed or emitted from the process of electron promotion or demotion can also be observed as an overall color for the element. I plan on practicing the equations more to better my learning so that I get them down and know what exactly each symbol stands for.

Exploring isotopes and average atomic mass (EXPLORE LAB WRITE UP)

In this lab the question we were trying to answer was "What is the atomic mass of beanies?" What we did in this investigation was find the atomic mass of beanium, we did this by multiplying each mass by the abundance (%) then adding them together (all 3 of the types of beans) and dividing them by 100. Our claim is that the atomic mass of beanium is .41g.

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.

3 Question Blog #3 ( September 29, 2017)

Over the last two weeks the tasks we've completed were our chapter one test, an isotopic abundance PHET, and a mixture separation lab. I've recently learned that isotopes are atoms with the same number of protons but different numbers of neutrons. They have different atomic weights and isotopes are different forms of a single element. To improve my understanding and reinforce my learning for the next two weeks I will study more efficiently for test number two and actually use what I learned and apply myself to the material.

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

Exploring Changes in Matter

In this lab we conducted an experiment about exploring changes in matter. The question in which we were trying to answer was "Which changes were examples of a chemical change and which were examples of a physical change."  A physical change is when nothing new is made, things stay the same. In a chemical change, you get something new and different that wasn't there before. During this lab we had five tasks to complete. Each task consisted of adding ingredients together and observing the data to determine if  a chemical or physical change has occurred. The first task we completed was 100g of water mixed with 5g of table salt. The second task was a small wad of copper wire is placed in a crucible and heated. The third task was five drops of sodium hydroxide and five drops of copper(II) nitrate mixed together. The fourth task was adding five drops of hydrochloric acid to 2g of sodium bicarbonate. Then fifth and final task was paraffin wax subjected to heat in a hot water bat
