Explorer Research Project

Explorer Research Project
Lauren

A few weeks ago I was assigned an Explorer, Ferdinand Magellan. I had to create a powerpoint presentation on google slides and share my results with a small group of my classmates. Lately, we have been learning about the Age of Exploration. Today, I will be sharing what I learned from my research and my reflection of this topic.

New Knowledge
After this assignment, I have acquired some new knowledge on Ferdinand Magellan. He was a Portuguese explorer who was born in Sabrosa in 1480. Ferdinand sailed for both Spain and Portugal during his navigation career. Magellan was the first to circumnavigate the world in 1519, which was funded by Charles V of Spain. Ferdinand Magellan also discovered the strait that connected the Atlantic to the Pacific. (AKA the "Strait of Magellan") He also acquired new knowledge of land and sciences. He died in the Mactan Battle in 1521.

Reflection
I really enjoyed giving and watching these presentations. I think that…

Analysis on Experiment

Image
Analysis on Experiment Lauren Kennedy, Emilie Mutoniwabo, Jamie Lanzen, Rebecca Baril Our experiment was testing out how different types of vinegar mixed with baking soda can change the distance a plastic water bottle travels when baking soda and vinegar are mixed in the water bottle. Our hypothesis was that the apple cider vinegar was going to make the rocket move the farthest, because it had the most acids, such as acetic acids and amino acids. During our experiment, we found out that neither of the types of vinegar made the water bottle move at all. All it did was foam out of the bottle, but it didn’t move.
If we do this experiment again, a couple things we might do are get a lighter water bottle or add in more vinegar and baking soda to result in more of a chemical reaction. This image shows our bar graph used to represent our data. Google Document

Matter

I watched a couple of brainpop videos about matter. I decided to share my newly refreshed knowledge.
Summary of Knowledge: (Measuring Matter)

Mass, Volume and Density are all physical properties of matter that are used to measure matter. Matter is anything that has mass, and volume. We measure matter to identify unknown substances, compare substances, and standardize those measurements. To find the mass of an object, measure the object on a digital scale, or a triple beam balance. This method is successful because on milliliter is equivalent to 1 cubic centimeter. To find the volume of an object, multiply it's dimensions, (length x width x height) or displace that object in water. Density is the measure of how tightly packed the atoms are inside of it. To find the density of an object, divide mass/volume.

Matter is anything that has mass and volume. Matter is made up of atoms. Atoms can chemically combine with other atoms and form a new …

Lesson 6: Five Number Summary

Welcome to the sixth part of the Data Analysis Series! In this lesson we will be learning how to find the five number summary.

Lesson 6: Five Number Summary

What is a Five Number summary? A summary of all the main points within a data set, splitting it into four sections each with a value of 25%

Here is an example of a data set.
68, 73, 78, 80, 83, 85 , 86, 90, 96

The first part of the five number summary is the minimum, the number with the least value (68)

The second part of the five number summary is the maximum, the number with the greatest value (96)

The third part of the five number summary is the median, the number in the middle (83)

The fourth part of the five number summary is the lower quartile, the median of the lower half (75.5)

The fifth part of the five number summary is the upper quartile, the median of the upper half (88)

Lesson 5: MAD

Welcome to the fifth part of the Data Analysis Series! In this lesson, we will be learning about calculating MAD.

Lesson 5: MAD

What is MAD? MAD is the summary of how much the values in a data set vary or clutter.
This is an example of a data set.
10,11,11,12,13,15

To find the MAD of a data set, we first have to find the mean of all the numbers.
10+11+11+12+13+15= 72
72/6 = 12

Next, we have to find the absolute value of the mean (12) and each of the numbers in the data set.
l10-12l = 2
l11-12l =1
l11-12l =1
l12-12l =0
l13-12l =1
l15-12l =3

Then, we have to find the mean of these new numbers.
2+1+1+0+1+3= 8
8/6= 1.3333333..

So, 1,333333.. is the MAD of the data set.

Lesson 4: Histograms

Welcome to the fourth part of the Data Analysis Series! In this lesson, we will be learning about histograms.

Lesson 4: Histograms

What is a Histogram? A histogram is a diagram consisting of rectangles whose area is equal to the amount of a variable and its width is equal to the interval.

This is an example of a Histogram.

Now let's answer some questions!

How many hours were studied? 5+4+3= 12

Which interval does the median fall? 4-5

How many hours were studied for students 4-5 and over? 4+3= 7



Lesson 3: Unknown Values (Mean)

Welcome to the third part of the Data Analysis Series! In this lesson we will be learning about unknown values. (mean)

Lesson 3: Unknown Values (Mean)
What is an unknown value in a mean question? A question that asks for the unknown value in a data set.
This is an example of an unknown value mean question: Katie buys 6 hair ties. These are the costs of the hair ties: 16,19,22,30.50,41.50,___The mean price is 25.50. What is the cost of the 6th hair tie?
There are two ways to solve this problem: Trial and Error: Add up all of the known values. Divide by the number of units (in this case, hair ties). Trial and Error the unknown value until you reach the correct mean. Check your work. 16+19+22+30.50+41.50= 129 Unknown value: 24
Checking:
16+19+22+30.50+41.50+24= 153
153/6= 25.50

Backwards: Add up all of the known values. Multiply the number of units (in this case, hair ties) by the mean. Subtract the known values from the product of the units and mean. Check your work. Example: 16+19+22+3…

Lesson 2: Observing Dot Plots

Image
Welcome to the second part of the Data Analysis Series! In this lesson, we will be learning about observing dot plots.

Lesson 2: Observing Dot Plots

What is a Dot Plot? A Dot Plot is a numerical chart that organizes various numbers on a plot.

This is an example of a Dot Plot. First, we have to organize the numbers in order of value. 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 4, 4, 5, 5, 5
Now, let's answer some questions!
How many people were surveyed?  28
How many people had 4 family members or more? 5
What is the median number of family members in this survey? 3
What is the mean of family members in this survey? 2.78

Lesson 1: Mean, Median, Mode and Range

This week I am taking a test on Data Analysis. I am going to make a series of blog posts covering each of the standard topics that I will be tested on this Friday.

Lesson 1: Calculating Mean, Median, Mode and Range.
In this lesson we will be using the numbers from this example:
20, 22, 22, 26, 27, 29, 32
To find the mean in a data set, add all of the numbers and then divide the total by amount of numbers that are in the data set.
Example:
20+22+22+26+27+29+32= 178
178/8= 22.25

To find the median in a data set, simply cross out one number at a time on each side.
Example:
20, 22, 22, 26, 27, 29, 32
The median in this data set is 26.

To find the mode of a data set, identify which number is used the most.
Example:
In this data set 22 is the mode because it is used twice, and all the other numbers are only used once.

To find the range in a data set, subtract the maximum from the minimum.
Example:
32-20= 12


Motivational Speech Practice

I have always thought about the question,
"What do you want to be when you grow up?"
And after 12 years of contemplation, I have come to the conclusion that I would like to be a Motivational Speaker. So I decided to practice. I took some of my ideas from the nike motivational video called "Rise and Shine, Welcome to the Grind" Here is my practice speech, inspired by that video.

Leave No Dream Behind Lauren Kennedy What do you want in life? Just ask yourself that, you don’t need to come up with the answer right away, just think. Never let anybody tell you that you can't. Never let anybody tear you apart. I know it may seem hard now, but the only person that is stopping you is yourself.

One step toward living your dreams is to become friends with yourself. Becoming friends with yourself can give you Confidence, Honesty, Trustworthiness, Respect, Humbleness, and many more qualities that can help you live your life to the greatest potential. It doesn’t matter how ma…

Surface Area VS Volume

Image
In math we are learning about Surface Area and Volume. I was talking to my peers this morning, asking them, "Which one is harder? Surface Area? Or Volume?" Four of seven students think that Surface Area is harder. This is why I am going to explain how to calculate Surface Area and Volume today.

Here is an example of a Three-Dimensional prism.
To find the Surface Area of this rectangular prism we first have to multiply the dimensions to find the area of each face. To find the Area of the top and bottom faces, we would multiply 4x3x2= 24. To find the area of one of the sets of faces, we would multiply 4x5x2= 40. To find the other set of faces, we would multiply 3x5x2= 30. Now, because we have all the calculations, we have to add the area of the faces together. 24+40+30= 94, so the Surface Area of the rectangular prism is 94 units squared.

To find the Volume of the prism we would multiply 3x4x5= 60, so the Volume of the rectangular prism is 60 units cubed.

It amazes me how the…
