Keyshuna takes notes on the physical properties of two objects. Based on the properties listed, which of the objects is most likely a metal?
Object 1, because it is a solid that is less dense than water.
Object 2, because all metals float in water.
Object 2, because metals conduct thermal energy and electricity.
Object 1, because it can be used to provide insulation for thermal energy.
Elijah is observing a beaker containing maple syrup and a bolt. Mrs. McCarty asks him to remove the bolt without touching the syrup. He tried to use a strong magnet to remove the bolt, but it remained on the bottom of the container.
Which of these best describes some of the bolt's physical properties?
The bolt is magnetic and has the same density as the maple syrup.
The bolt is nonmagnetic and more dense than the maple syrup.
The bolt is nonmagnetic and less dense than the maple syrup.
The bolt is magnetic and less dense than the maple syrup.
A bucket contains a mixture of wood blocks and rubber erasers. The easiest way to separate the wood blocks from the rubber erasers would be to –
place the bucket onto a heat source
run a magnet through the bucket
pour the mixture through a filter
add water to the bucket
Which two objects are less dense than water?
wood block and metal paper clip
plastic ball and glass marble
metal paper clip and glass marble
wood block and plastic ball
Using the picture, tell me which object is the least dense and why?
The fish because he is in the middle
The cork because it is floating at the top of the water
The rock because it is at the bottom
The cork and the rock because they have the same about of atoms.

Which statement correctly describes the difference between climate and weather?
climate refers to elevation and weather refers to temperature of clouds
weather refers to the conditions in the atmosphere and climate refers to average weather over time
weather refers to rainfall and climate refers to temperature
What is the condition of the atmosphere at a certain PLACE and TIME called?
weather
thunderstorm

climate
Why is the sun important to the water cycle?
The sun is the source of energy that powers the water cycle.
The sun gives light so that people can see the water cycle happening.
The sun's gravity causes the tides which are important to the water cycle.
The sun isn't important to the water cycle.
Climate is different than weather because
Weather is short term, climate is over long periods of time
Weather deals with precipitations, climate with temperature
Climate deals with precipitations, weather with temperature
Weather and climate are the same
The average weather conditions of a region-
daily temperature
weather
climate
