Answer 1

The best example of a job performed by slaves in the Southern colonies is harvesting cash crops.

What is Cash crops?

• A crop farmed for commercial purposes is known as a cash crop or profit crop. Usually, parties unaffiliated with farms buy it.
• The word is used to distinguish between marketed crops and staple crops (also known as "subsistence crops") in subsistence agriculture, which are those that are farmed for the producer's family or own livestock.
• Cash crops used to make up a small but important portion of a farm's overall yield, but today, especially in developed nations and among smallholders, almost all crops are grown primarily for commercial purposes.
• Cash crops are typically those that draw demand from more developed countries in the least developed ones and hence have some export value.

Answer 2

Answer:1. Using two to three sentences, summarize what you investigated and observed in this lab. In this lab, I tested the physical properties of many building materials and how they might be used in construction. I tested the materials for flexibility, magnetism, thermal conductivity, electrical conductivity, and density.

2. What building material did you use to build your house? Did your results support or fail to support your hypotheses? I used brick clay, iron, copper, aluminum, and nickel to build the house. My results supports my hypotheses.

3. What were the densities of the materials you chose for the walls and floor for the home in Tiny World? Why do you think a building material's density is important when building homes or architectural structures? The densities of the materials I chose for the walls and floor for the home in Tiny World are 1.06 cm and 1.05 cm. The building material's density is essential when building structures because it determines how much the material weighs and how strong it is.

4. Why wouldn’t you choose wood or aluminum for the latches on your house? I would not choose wood or aluminum for the latches on the house because they are not strong enough.

5. Which material has the highest thermal conductivity? Which material has the highest electrical conductivity? Explain why thermal and electrical conductivity is so high with this material. The material with the highest thermal conductivity is copper. The material with the highest electrical conductivity is aluminum. Thermal and electrical conductivity is high with these materials because they are good conductors of electricity and heat.

6. Think about where you live now or where you have lived in the past; use complete sentences to describe this environment and the weather. What building materials do you believe would work well to build a home in that area? Explain why you chose these materials.  I live in a temperate climate with average weather that sometimes can get hot. I think that building materials that would be well to build a home in this area are wood, brick, and stone. I chose those materials because they are strong and long-lasting.
