Question

how concrete is made
introduction
in this activity, you need to find reliable internet sources that 1) explain how concrete is made and used, and 2)
describe its positive and negative impacts on society. you will also apply what you have already learned in the
lesson. youll need to find out about the ingredients, such as cement, that are mixed together to make
concrete. for example, concrete is used in construction to meet peoples needs. but it also requires the mining
of natural resources.
you might find reliable information about how concrete is made by looking at the websites of companies that
make it. trade organizations, such as those for construction workers and builders, are likely to have
information about the ways concrete is used. however, these sites are unlikely to have reliable information
about any negative impacts of concrete. instead, try to use government, university, or respected news sites to
find that type of information.
in part 1, you will start by finding websites with information you can use in your research. the questions in part
2 will help you take notes. in part 3, you will make a flowchart that summarizes the information youve learned.
