PRACTICE ACTIVITY

Did you understand? Look at the notes under each topic. The sentences in the notes refer to either the major points or the minor points. Try to organize the notes under the topic by putting the major points in the left column and the minor points in the right column. Your answer is correct if the points are placed correctly on either the left or right. The points do not have to be in exactly the same order. The first one is completed to give you an example.

EXAMPLE

There are three types of managers in addition to the general manager.

The line manager is responsible for production.

For example, a production manager is a line manager.

A staff manager is in charge of support activities such as human resources.

Information systems is also overseen by a staff manager.

A functional manager is the head of a department.

A department chair at a college is a functional manager.

The manager of a sales department at a company is also a functional manager.

1. According to Mead, the self has two sides: the "I" and the "me."

It is predictable because social conformity is expected.

This part of the self is less predictable because it is unique.

This part of the self is formed through socialization by others.

The "I" represents the individuality of a person.

For instance, a spontaneous reaction might reveal the "I."

The "me" represents the expectations and attitudes of others.

2. The mystery of pulsars was resolved in the 1960s.

We see pulses of light each time the beam sweeps past the Earth.

The pulsar in the Crab Nebula, for example, currently spins about thirty times per second.

We also know that pulsars are not perfectly timed because each revolution of a pulsar takes a little longer.

We know that pulsars are neutron stars, like lighthouses left by supernova explosions.

It will probably spin about half as fast two thousand years from now.

Like a lighthouse, the neutron star revolves.

3. Britain transported convicts to Australia in an effort to solve the problems of overcrowding in prisons.

There were 11 ships with 750 prisoners aboard.

Four companies of marines sailed with them as guards.

They took enough supplies for two years.

In 1787, the first fleet left for Botany Bay in New South Wales.

Shortly after arriving in 1788, the colony was moved to Sydney Cove.

In Sydney, the water supply and soil were better.

Although Sydney was the new site, for many years it was called Botany Bay.

4. Frederick Carl Frieseke was an American impressionist.

In Normandy, he began to paint indoor settings.

In 1905, Frieseke moved to Giverney where he lived until 1920.

He studied with Whistler in the late 1800s.

Born in Michigan, he went to Paris in 1897.

In his later work, he began to use a darker palette.

From Whistler, he learned the academic style of the salons.

At Giverney, Frieseke was influenced by Monet.

Monet was experimenting with the effects of sunlight.

The style of Monet and his school is known as impressionism.

By 1920, Frieseke had left Giverney for Normandy.

5. Two types of weathering will break down rock masses into smaller particles.

Interaction between surface or ground water and chemicals causes chemical weathering.

With increased precipitation or temperature, chemicals tend to break down faster.

Mechanical weathering occurs when force and pressure grind rocks down.

A common example is the wearing away of granite facades on buildings.

The weathering of feldspar in granite can be caused by a reaction to acids in rain.

Pressure from freezing and thawing causes rocks to expand and contract.

When a rock is broken in two by physical forces, it is more vulnerable to weathering.
