How do you write a hypothesis. Please give general form.
What is " If you change something and you measure something, then you will observe something because of something?
100
The variable that the scientist measures.
What is a dependent variable

Plants grow in bright light conditions because light provides the energy that they need to build new cells.
What is an inference?

There are ___________ meters in 5 km.

Write a hypothesis for the following scenario. The student wants to compare the amount of protein in Jell versus eggs. They use Biuret Solution to detect the protein and observe a much darker purple color for the jello. Purple color indicates protein is present.
What is If you test both Jello and eggs with buret, and you measure the shade of purple. Then you will see that eggs have more protein, because the color was much darker.

The variable that the scientist changes.
What is an independent variable?

The rat population explosion at the same time that the bamboo forest produced vast amounts of fruit.
What is an observation?

Superman and Spiderman want to decide once and for all who has the quickest reaction time. They set up an experiment where they have to avoid projectiles flying at them. The one who comes out unscathed wins.
If I compare how well Superman and Spiderman can dodge flying projectiles and I measure the number of times that they get hit, then I will see who has the fastest reaction time, because they will need to be fast to avoid the stuff I will throw at them.

The parts of the experiment the scientist keeps the same.
What are the controls?

A plant grew in height from 2 cm to 5 cm in a three day period in bright light conditions.
What is an observation?

There are __________km in 420m.

I want to know where Mr. Brown was poisoned. I can identify the types of foods he ate by testing the macromolecular composition with Iodine, Biuret and Benedict's Solution.
If I test Mr. Brown's stomach contents for Iodine, Biuret and Benedict's and I measure the color changes for each test then I will find that he tested positive for Iodine and Biuret, because he ate at Ruth's Chris and ordered steak and potatoes.

Identify the independent and dependent variable given the following lab purpose. How does plant growth differ when a seed is sprouted in the dark and then is kept in the dark, instead of sprouting in the dark and moving to the sun?
Independent variable dark/light dependent variable - growth of plant (number of leaves, color, and height)

I want to know what chemicals make up the fantastic fireworks. I know that I can do a flame test, where I look at the color of the flame for 5 known metals and compare those flames with the unknown fireworks.
If I test 5 known flames to the unknown and compare the colors produced, then I will be able to identify the unknown because they will have the same color flame.
