States of Matter
What is a solid?
This would change if you traveled to the moon from Earth
What is your weight?
Purple cabbage juice turns pink when you add an acid to it. This is what the purple cabbage juice is called in this experiment. (a substance that changes in the presence of another substance)
What is an indicator?
a mixture in which the substances are evenly distributed is called this (like a drink powder mixed in water)
What is a solution?
Plastics are made by man from fossil fuels. (True or False)
What is true?
State of matter with the greatest amount of kinetic energy
What is a gas?
If an object sinks or floats, is based on this
What is the objects density?
What is starch? **we specifically used corn starch
The process used to separate larger particles, like sand, from a liquid.
What is filtration?
The area in the pacific ocean that is over 600,000 square miles, where waste and plastic floats
What is the Great Pacific Garbage Patch?
During a phase change, going from liquid to a gas for example, the temperature (stays the same, decrease or increases)
What is stays the same?
What is gravity?
During our mysterious substance investigation, we used Benedict's solution to perform tests on coke, orange juice, milk and pepsi zero. We were looking for this.......
What is sugar?
While stranded on the island, I made pure drinking water from the ocean salt water by this process
What is distillation?
Recycling is a great way to reduce plastics and other materials that do not biodegrade that does not use natural resources to do. (true or false)
What is false? **recycling or any process of making a replacement for a plastic container for example, requires the use of natural resources (fossil fuels, wood, water, etc) to create.
If the temperature remains the same, the kinetic energy remains the same. (true or false)
What is true?
A log and a branch from the same tree have the same density - if the log floats, the branch floats (true or false).
What is true? **density will remain the same because the mass and volume change in the same way
Sugar dissolves quickly in water versus salt that takes longer. This has to do with this property of the sugar and salt
What is solubility?
Process I used to remove the iron filings from the sand I collected
What is magnetism?
The repeating chains of molecules that make up plastics
What are polymers?
This happens to thermal energy as particle movement decreases (increase or decrease)
What is decrease?
The formula for finding density
What is density = mass/volume?
a substance that is only one specific element or compound throughout, like water or oxygen for example, is known as this type of substance.
What is pure?
What is liquid to gas, back to liquid. (vaporization to condensation)
Plastics have (negative, positive or both) impact(s) on our environment.
What is both? **how? - explain
