Introduction to Chemistry:

The 5 Types ofChemistry White Board Activity:

In this activity we learned the names and what is involved in each type of chemistry. Each group made white board presentation of their type of chemistry and had hands on examples of what their chemistry would study. In this activity I learned that the five different types of chemistry are Organic, Inorganic, Physical, Analytical, and Biochemistry.

My group had Organic chemmistry. Organic chemistry studies matter containing carbon. We learned from other groups that Inorganic chemistry studies matter that doesn't contain carbon. Physical chemistry studies the behavior and changes of matter and related energy changes. Analytical chemistry analyzes food and what's in it. And Biochemistry is the study of matter and the processes of living organisms.

Data Analysis

Chemistry: Scientific Notation:
 

On this worksheet we did lots of practice of changing numbers from standard form into scientific notation and from scientific notation into standard form. We learned that if 10 is in the power of a positive exponent then you move the decimal of your base value, that is being multiplied by 10, that many places to the right. If you have a negative exponent you would move the decimal to the left. The base number is always in a standard form with only one digit to the left of the decimal and only significant digits are listed. I enjoyed this worksheet because scientific notation is easy for me.

On this worksheet I learned that you can multiply and divide numbers that are in scientific notation. I enjoyed the busey work and that we could use our calculators!

Chapter 3:

Matter-Properties and Changes

Law of Conservation of Matter Math Problems:

In this activity I learned that matter can't be destryoed or created in a reaction. We solved problems where we had to find the missing variable for how much of an element was created in a reaction. For example if you have 89.4 g of water and it produced 10.0 g of hydrogen then we know that 79.4 g of oxygen was also produced.

I liked this activity because I love math, and understand the concepts of algebra.

Chapter 4 Reflection on:

History of The Atom White Board Activity:

For this activity we made white boards on a subject with a group. Each subject studied a part of the history of an atom. My group studied the three particles: electrons, neutrons, and protons. We learned that the protons charge is positive, electrons have a negative charge, and neutrons are nutral. We also learned that the exact mass of an electron is 9.11x10^-28, a proton is 1.675x10^-24.

Chapter 5 Reflection on:

Bohr Models Packet:

In this packet we drew way too many bohr models. For each element listed we drew a diagram of how the element is represented by a bohr model. We learned that first you write the number of protons and neutrons in a circle. You draw more circles around it and the number of electrons. The first ring can only hold 2 electrons, the second ring can hold 8 electrons, the third ring can hold 18 electrons, and the fourth ring can hold 32 electrons.

Chapter 6 the Periodic table and periodic law and 7 the elements:

Reflection on:

Element autobiography:

While doing the element autobiography I learned all about Uranium. We studied one element that we chose and had the write a one page autobiography of the element in first person. I learned that Uraniums atomic number is 92, it is used in nuclear weapons and it isn't found as a pure substance. It is normally found in a compound called unihexiflouride. I also learned that it was named after Uranus because they were both discovered around the same time. If I could do this project again I wouldn't write a poem, It was very difficult to think of ways to write rhyming words for all of the scientific words that I had. 

Chapter 8: Ionic Compounds

Reflection On: Determining Chemical Formulas

In this activity we cut out elements with a zig-zag side and matched them up with a different element until the elements completed a rectangle. This lab helped me learn how to determine how many of each element (according to their charges) belongs in the chemical compound. We also were given a list of 40 chemical compounds and we had to show the chemical formula for each compound. I really enjoyed this worksheet because I liked determining the numbers of each element to create the right compound.

Chapter 9: Covalent Bonding

Reflection on: Chapter 9 Worksheet Packet

In this packet I learned how to draw the Lewis structures for chemical compounds. I learned that elements can form single, double, or even triple bonds. I learned how to organize the electrons that are left over balance out the number of bonds and lone electrons. In this packet I also learned that there are exceptions to the octet rule, some exceptions include an expanded octet and a reduced octet. I liked this packet because i thought drawing the models was fun.

Chapter 10: Chemical Reactions

Reflection On: Parts of a Balanced Equation Packet

In this packet I learned how to Balance a chemical equation. I learned how to count how many of each element are in a compound. Then i also learned how to multiply the compound so that each side of the equation have an equal amount of each element using coefficients. I liked this packet because it helped me get comfortable with balancing equations.

Chapter 11: The Mole 

Reflection on:Empirical and Molecular Formula Worksheet:

In this worksheet we did lots of practice with changing compounds into their simplest form, the empirical formula. First you take the mass of each atom in the compound and add it up. This is the compounds molecular mass. Then you divide how many grams of the compound you have by the compounds mass. You multiply each atom by your answer to get the molecular formula. I liked this worksheet because I enjoyed the math.

Chapter 12: Stoichiometry:

Reflection on: Stoichiometry and Percent Yield Worksheet:

In this work sheet we practiced changing a worded problem into an equation, and then setting up a BCA table. Before we could put any numbers into the BCA table we had to convert the grams of a compound to moles. Then we calculated the molar mass of each chemical in the equation using mold ratios. After you added the final numbers for each chemical together you took the unknown chemical you were solving for and convert it back to grams. This helps us know what will be produced in the lab when we are given a certain amount of a chemical.I enjoyed this worksheet because I like the math. 

Lab Reflection:
Density Inquiry Lab:

In this lab we had to calculate the density, volume, and mass of 14 different materials. We used the scale to discover the mass, either the euation for volume or water displacement method to find the volume, and mass divided by volume to find the density. Once we found the density we looked up the density on a chart to figure out what the substance actually was.

This lab was challenging because of how precise you had to be with all of your calculations. I liked it because it was alot of calculating.

2nd Quarter Lab Reflection:

Lab #6 Flame Test Kit:
 

In this lab we put different chemicals on the ends of a popcicle stick and burt it over a bunson burner. We observed the color addmitted in the flame. We took the color of the flame and found out how long it wavelength is. Then we took Plancks constant times speed, divided by the wavelength to find the frequency of the flame. This took alot of math and time, but it was cool to be able to figure out that much information just by observing the flames color.

3rd Quarter Lab:

Reflection on Lab #8

Periodic Table Kit:

In this lab we tested elements to find common patterns or trends that elements follow within groups for reactivity. We tested different Alkaline Earth Metals to see how each reacted to different chemicals. I learned that as you move down in a group the reactivity increases. I liked this lab because it was fun to watch the reactions and it was simple. 

4th Quarter Lab Reflection:
Reflection on: Lab #12: The Bean Lab

In this lab we used different sizes of beans to understand the concept of moles. First we counted out 100 beans. Then we weighed them. Next we calculated the mass of each type of bean relative to the bean with the smallest mass. Then we calculated the average mass of one bean. Then we calculated the relative mass of the type of bean compared to the lightest bean. Then we calculated the number of beans in one relative mass. We learned that this is how they calculate one mole of each atom. They take the atomic mass on the periodic table divided by the mass of one atom and each element came out to the number 6.02x10^23. I liked this lab because I thought it was cool to know how the mole is calculated.

Uncertainty in Measurement Activity:
 

In this activity everyone measured one of the small white boards with rulers that measured "nerds". We all found the area of the white board using three different rulers: one that measured only 1-10, one that measured every whole number between 1 and 10, and one that measured to the tenth of every whole number between 1 and 10. It was difficult because we learned that you can round one decimal place past the place value that your utensil measures. Each person had their own perspective on what the number they rounded to was. We got the results of five other students to compare our answers then we were told the actual measurements of the white board. It was a fun and frustrating activity.

Choice Reflection for Quarter 2:

Chapter 5: Lewis Dot Structures Packet:
 

In this packet we learned how to draw Lewis Dot structures. In the Lewis Dot structure you take the element symbol and draw around it how many valence electrons it has. You start on the right side and move your way around the symbol at 3, 6, 9, and 12 o'clock, putting one dot at each spot representing a valence electron. There can only be up to 8 valence electrons resulting in 4 pairs of dots around the element symbol.You can figue out how many dots to draw by looking at which family the element is in on the periodic table.

Reflection On:

Chapter 8: Bond with A Classmate activity

In this activity each person was given an element with a charge written on the tag. We walked around and found a person who had an element of the opposite charge. Then we calculated how many of each element was needed to balance the charge so that the equation had no charge. I learned that if you have an element with a charge of 2+ and an element with the charge of 1- you have to combine two of the 1- elements with one of the 2+ elements. I liked this activity because we got to be interactive and it was simple.

4th Quarter Choice Reflection:

Chapter 12: Mole Relationships Worksheet

In this worksheet we practiced making BCA tables and learned how to calculate what will be made in a chemical reaction before the reaction actually takes place. First you write down your given amounts in the before section, and put zeros in for the products. In the change section you put numbers in using the balanced equation with the given amount, in mole ratios. Finally in the after line you add up the amounts that you are left with and you will see how much chemicals you produce. I liked this worksheet because it was easy for me.
