Derrick created a table of his observations from one trial of an investigation into whether a charged object will attract or repel an uncharged object.
Which statement best explains an incorrect conclusion you might believe without repeated trials?


Object Trial 1
negatively charged attract
positively charged nothing

A) Negatively charged objects repel uncharged objects.
B) Negatively charged objects are attracted to uncharged objects.
C) Positively charged objects do not attract or repel an uncharged object.
D) Positively and negatively charged objects react differently to uncharged objects.

Positively charged objects do not attract or repel an uncharged object. The correct option is C.

Electrostatics is the study of stationary electric charges. Electric charge is the charge associated with matter that causes it to create and experience a magnetic and electric effect.

When a plastic rod is touched with fur or a glass rod is rubbed with silk, pieces of paper are attracted, indicating that both rods are electrically charged.

Two particles with opposite charges repel each other, whereas two particles with opposite charges attract each other (see Coulomb's law). The electric force between two charged particles is substantially stronger than the gravitational force.

Therefore, the positively charged objects do not attract or repel an uncharged object. The correct option is C.

Caleb is investigating the effect of friction on the motion of an object. He uses the following supplies for the investigation:

a wooden block
three ramps, each ramp is the same height and length but has a different surface (smooth wood, carpet, rough sandpaper)
a stopwatch
Caleb tests his hypothesis that the smooth wood ramp surface causes less friction than the carpet and that the carpet causes less friction than the rough sandpaper.
(THERE IS A PART "A,B,C")

A: Neutrons
B: Protons
C: Electrons

Sarah and Charlie both investigated the properties of rocks they found while on a walk. Take a look at the table with their observations. What was the difference between the two sets of observations?


Sarah's Observations Charlie's Observations
The mineral was metallic. The mineral was non-metallic.
The mineral had cleavage. The mineral did not have cleavage.
The mineral was red. The mineral was red.
The mineral had luster. The mineral had luster.

a Sarah observed that the mineral was metallic and red.
b Charlie observed that the mineral was red and had luster.
c Sarah observed the mineral had cleavage and was metallic.
d Charlie observed the mineral was non-metallic and had luster.

When rain falls to the earth, it just doesn't sit there. Instead, the rain water starts moving. Some of the precipitation seeps into the ground to replenishing groundwater. However, most of it flows downhill as runoff. Runoff is important in filling rivers and lakes, but it also changes the landscape by erosion and can be a powerful mover. Flowing water is a powerful force, capable of moving boulders and carving out canyons. Runoff has an impact on streams and rivers, but it also has an impact on the ocean system. What can you infer about the impact of runoff on Ocean life? Choose ALL that apply.


A) Runoff drops a lot of sediment in the ocean, decreasing salinity.

B) Runoff builds up the coastline, depositing sediment, disrupting habitats of marine wildlife.

Runoff can lead to overgrowth of algae that can cause oxygen deprivation and create a dead zone.

C) Runoff carries pollutants into the ocean, causing illness and death of vulnerable marine populations.

D) Runoff can carry bacteria, viruses, and other pathogens from pet and livestock waste that can harm shellfish and other marine organisms.

There are many uses for permanent magnets and temporary magnets like an electromagnet. Electric appliances with electric motors use magnets to turn electricity into motion. Other examples include electric toothbrushes, fans, lawnmowers, and anything else containing a motor.
Magnets are used to hold doors closed, such as in refrigerators, kitchen cabinets and others. Magnets are also used to read and write data on a computer's hard drive or on old-fashioned cassette tapes. There are more magnets in headphones and stereo speakers which help to turn stored music back into the sounds you can hear.
In summary, magnetism is another property of some kinds of matter. There are two poles to a magnet, the south pole and the north pole. Like poles repel and unlike poles repel. There are two different kinds of magnets, temporary and permanent. A temporary magnet can be made by using electricity. All magnets contain an invisible electromagnetic field which surrounds the magnet. There are many uses for magnets, from holding doors closed to helping music sound better with the magnets inside of speakers.

Based on the information provided above how would you describe a magnet?
