A student wrote a report about the telescopes used to investigate space. He explained that since telescopes cannot see why the end of the universe, there might be different universes. Why is the student's explanation NOT scientific?
It cannot be true.
It cannot be tested.
It is not a new idea.
It is based on incorrect facts about telescopes.
Which of these questions is NOT a question that can be tested using science?
How does fertilizer effect the growth of plant roots?
Does increasing the height of a ramp make a toy car travel farther?
Does adding salt to water change the tempature at which the water freezes?
How can the position of stars be used to predict what will happen in people's lives?
Scientists who make new discoveries or find new evidence to support an idea often publish their methods and the results of their expiriments in scientific journals so that other scientists can test their can test their discovery. Why is it important for other scientists to repeat an investigation and get similar results?
To make sure the results and conclusions are correct.
To find out if diffrent methods will get the same results.
Because a discovery can only be true if it has been tested by many other scientists.
Because the methods and results can be improved by new ideas from other scientists.

Ability to fill a container of any shape.
In which example is a liquid changing into a gas?
Soup boiling
Juice Freezing
Ice Cream Melting
Water Vapor Condensing.
An electronmagnet is a device that creates a magnetic field when electricity passes through it. Troy watches as a huge electronmagnet in a junkyard picks up objects. An employee at the junkyard tells him that the electronmagnet can lift up to 3000 pounds of materials that are attracted to it?
which object is the electronmagnet most likely to pick up?
An Aluminum Can.
A Glass Windshield.
A Plastic Crate.
A Steel Door.
Which Mixture would most likely be easily separated with a strainer?
Salt and Sugar
Gravel and Sand

scientists who make new discoveries or find new evidence to support an idea often to publish their methods and the results of their experiments in scientific journals so that other scientists can test their discovery. Why is it important for other scientist to repeat an investigation and get simular results?
To make sure the results and conclusions are correct
to find out if different methods will get the same results
Because a discovery can only be true if it has been tested by many other scientists
Because the methods and results can be improved by new ideas from other scientist
Scientist journals often report more than results of experiments. Careful descriptions of all the procedures can also be found in many of the articles.
Why do scientists include descriptions of their experiments in addition to their results?
That is how scientists have always written their articles.
They want to show that they were the first ones to do the experiment.
Including the steps helps other scientists to preform the experiment and check the results.
Including the steps is helpful to students who are researching the topic and need to include steps.
Two children are playing a guessing game about the diffrent properties of matter. One of the students wants to give a clue about gas.
Which sentance would be the best clue for the student to give?
It will fill its container
It takes the shape of its container
It has its own shape and structure
It can be held in a person's hand
