The Physics of Dance

Our experiments will be focusing on the natural forces a dancer encounters when completing turns and leaps. The research we completed today included multiple youtube videos listed below, helping us to understand and explain the physics in specific dance moves.

Harwood vs. Baloney detection kit

The Baloney detection kit really focuses on the steps one can take to decide whether or not something is true. It provides examples and questions one can consider to help them understand what information to believe and what not to believe. These ideas are very important, especially since most of today's information is coming from the TV or internet which are not always the most valid sources.

The Harwood model provides readers with steps they can take to provide accurate information to outsiders. Using the steps in the harwood model, you can come up with an idea, test results and have all of the necessary information to give others about the results.

I think both of these models are important for students to consider when they are doing research or experiments. Not everything you hear or see is going to be true but if everyone used both of these models when completing research, the information people attain would be a lot more true. 

Research Question (Nicole, McKennzee, Courtney)

Research question: What liquids can be placed inside a balloon over a flame and prevent the balloon from popping?

Materials: Balloons, candles, water, fruit punch, soda, lemon juice

Hypothesis: We believe the water will prevent the balloon from popping in smaller quantities than the other liquids.

Differences in 2 wordle analysis

The first wordle had a lot more adjectives and used words that only described things that could be sensed, like color and feel. However, the second wordle used more specific terms, describing exact measurements and using more verbs.  Both documents describe a candle but they do it in very different ways.

Observations part two

Floats, slides, weighs 4 grams, opaque, unsturdy base, can be reshaped, greasy, crushable, 9.5 centimeters long, meltable, not magnetic, breakable, malleable, old, unique, holds a flame, no electric current, uneven, damaged, and produces smoke.

What do the observations have in common?
 They all describe physical features of different candles. The words describe things like color, size, consistency, shape and weight.
What were the most unique observations?  
"cheese," "film," "tail," "hot," "smokey," "crayon," "swiss," "3/8," "aluminum."
What senses were used?
Sight, smell, and touch
What tools were used?
Sight, ruler, hands, nose,

Observations Part one

Pink (light and dark), burnt, melted, skinny, stick-like, used, misshaped, tall, cylinder, has a tail that is black, solid, fragile, smooth, thin, irregular, looks like a straw, smells like strawberry, stripped, lightweight, and is often seen on birthday cakes.
