Finding My Volume

Here is the video I made about my science assignment-finding my volume. It is just about a minute long, and shows the two solutions I used to find my volume using water displacement.

My first solution involved water displacement. My plan was to fill up my bathtub till an amount in which I think I can fit my whole body in, mark the height, and submerge myself entirely into the water. After measuring the height of the water and marking it both before and after I went into the bathtub, I found my volume. I had displaced 6 centimeters high of water. (The water level was 24 cm before I went in and 30 cm while I was in the water.) I then had to multiply the height of the water I had displaced by the surface area of the water. I multiplied the width of the water (45 cm) by the length of the bathtub (125 cm) by 6 cm (the height of the water I had displaced). My product was 33,750 cm3, or 33.7 liters.

I wanted to check my answer with another solution. This was to fill up the bathtub to the second mark (the water height with me in it); then use my 500ml measuring cup and took out water, counting each full cup. To compare this method to my first strategy, I would need around 66 cups because 500ml x 2= 1 liter, and with the first method, I got 33 liters. Using this method, I got 64 cups, which is 32 liters. This means my volume is between 32 and 34 liters. 

Here are two assumptions I made before performing this experiment:

• My bathtub has the shape of a rectangular prism.
• My swimsuit and goggles do not have a significant enough volume to interfere with calculating my volume. 

54321+8 Promoting Wellness in My Community

Here is my Google Presentation for 54321+8. I worked on a SMART goal and sharing this presentation with my parents, then interviewing them about their wellness and this presentation.

Factor Rainbow or Factor Tree?

When is it better to use the 'factor rainbow' method, rather than the 'factor tree' method for finding factors?
I think it is better to use the factor rainbow method when the numbers are low, because there wouldn't be as many numbers to write down. For example when I need to find the LCM or GCF of 12 and 6, it wouldn't make sense to use the factor rainbow method. But using the factor rainbow method is quick since 12 and 6 are low numbers and don't have as many factors. It's better to use the factor tree method when the numbers are big because you don't have to write down as much. For example, finding the LCM or GCF of larger numbers like 84 and 48 or finding the LCM or GCF of multiple numbers like 24, 72, and 80.

8.5

8.5

TEN is a person who is dying to hit the stage on day one of drama and would willingly perform in front of all of 7th grade right NOW!  ONE is a person who would rather be ANYWHERE but the stage and would prefer to be wrapped up in a blanket back in their bed hugging their teddy bear. On this scale of one to ten, I would be an 8.5 because I really like acting and making other people laugh. I like to entertain people. I have had some experience with acting and drama, and I have really enjoyed it. I have always found pretending to be other people and being dramatic really fun. But, I am not the kind of person who would just hop onto the stage and perform. I do get nervous before I go onto stage, and sometimes shy. Even though I get nervous, I like the feeling of having nerves and butterflies in my stomach. I think it makes me do well on the stage, enjoy it more, and the whole thing feels real. I am looking forward to acting in drama class and showing people what I can do on stage. I do get nervous, but with the nervousness comes excitement! I am always excited to be on stage and get a chance to perform. 

What We Measure

Here is my 'What We Measure' table for science. I filled out the ones I knew, and tried my best on the ones I wasn't sure about. I left the boxes I was really stuck on blank.

Quantitative  Data Type	Instrument Used	Unit of Measurement
Mass	weighing scale/balance	Gram
Distance	meter stick	meter/kilometer
Volume (liquids)	beaker/flask	milliliter/liter
Volume (solids)		centimeters cubed, meters cubed
Temperature	thermometer	Celsius
Time	clock	minutes/seconds/ hours
Density

Neutral Actor Homework

For my neutral actor homework, I watched CSI: Miami 8.  Here are some things I noticed about the neutral actors or extras:

• The extras are walking both in front of and behind the main characters, but they are blurred, so it is hard to notice them.
• The extras are wearing all sorts of colours, but they are wearing regular street clothes.
• The extras are wearing few or no accessories.
• When the main characters walk out of a frame, there are no extras walking by. The extras are only a background for when the main characters are in a scene.
• The extras are wearing clothing that fits the scene (e.g. in a hospital, they wear nurse costumes)
• The main characters or an important object is always in the center.
• Some scenes just have the feet or arms of the extras showing, because the camera is focused on any object.
• The extras don't move or turn suddenly. 
• It is hard to focus on extras with the volume on because the main characters' expressions match what they say and make you feel things like suspense. This distracts you.
• The extras are doing things that match the scene (e.g. in an office, they are on laptops and looking at papers.) 

Parent/Student Agreements

This is the form for the parent handover for my laptop. I think I am responsible enough because I take care of other similar items (iPad, phone) and remember to charge those every night. Before I brush my teeth, I charge both my phone and my family iPad. I will now remember to charge my laptop at the same time. I am going to charge my laptop on my bedside.
