Problem: The properties of matter depend on the types of atoms that matter is made of. Matter can exist in two forms. It can be a pure substance. This means it is not mixed with anything. It can also be a combination of different substances. This means it can be a mix of different types of atoms. You may recall that atoms differ based on the numbers of protons they contain. Some atoms contain only one proton such as Hydrogen. Other atoms contain many protons. There are many types of atoms. For example, Helium has two protons. An Oxygen atom has eight. Water is composed of a two types of atoms. Water is made of two Hydrogen atoms and one Oxygen atoms. There are only so many types of atoms. These atoms can be mixed into an almost limitless amount of substances. So what do we call a substance that has only a single type of atom?

Question: "What are the two forms matter can exist in?"

Answer: "Pure Substance & A Combination of Different Substances"
Answer: yes

Problem: Earths magnetic field helps protect Earth and its organisms. It protects us from harmful particles given off by the sun. Most of the particles are attracted to the north and south magnetic poles. This is where Earths magnetic field is strongest. This is also where relatively few organisms live. Another benefit of Earths magnetic field is its use for navigation. People use compasses to detect Earths magnetic north pole. Knowing this helps them tell direction. Many animals have natural 'compasses' that work just as well. Birds like the garden warbler in Figure 1.36 use Earths magnetic field. They use it to guide their annual migrations. Recent research suggests that warblers and other migrating birds have structures in their eyes. These structures let them see Earths magnetic field as a visual pattern.

Question: "What do animals have naturally that people do not?"

Answer: "Antenna compasses"
Answer: no

Problem: Victims of domestic violence will have access to quality legal representation through a campaign undertaken by Idaho Supreme Court Chief Justice Linda Copple Trout and corporate leaders. "Thousands of times a year, Idahoans are victims of domestic violence. The victims are often women and their children and they frequently have few resources with which to pursue their legal rights," Trout said Tuesday. "This campaign helps fill that gap in legal services for women who need the help at a time when they are in crisis." The Idaho Partners for Justice Project has already secured pledges of more than $35,000 from law firms, attorneys, corporations and individuals. The goal is $100,000. The drive to pay for free legal services will continue for the next two months. The money goes to Idaho Legal Aid Services and the Idaho Volunteer Lawyers Program. Last year, more than 5,000 petitions were filed in Idaho for protection orders in domestic violence cases. More than 12,000 victims contacted shelters or crisis hotlines. Joining Trout in the announcement was Idaho Bar Association President Fred Hoopes of Idaho Falls and Ida-West Energy Co. Chief Executive Officer Randy Hill, members of the project's executive committee. Also on hand were some women who were victims of such violence, but benefited from free legal services. Last year's campaign generated enough money and resources to help more than 450 victims. The help ranged from representation in protection order hearings to legal assistance in divorce, visitation and child support cases. The donations are tax deductible.

Question: "How much longer will Idaho Partners for Justice Project solicit donations?"

Answer: "6 months"
Answer:
no
