Science Probe II Technology Activities
1.Synthesis reactions are very important in our everyday
lives. They are used to make petroleum products, ammonia, fertilizers,
and may other products. Decomposition reactions are used to produce metals
and many gases. Choose one substance that is produced by a synthesis reaction
and one substance that is produced by a decomposition reaction. Conduct
an Internet search to answer the following questions:
a. In what material is the substance found in nature,
and what is its chemical formula?
b. What chemical reaction is used to produce the substance?
c. How exothermic or endothermic is the reaction?
d. How much does it cost to produce this substance?
e. Where or in what is this substance used?
When you have completed your search and are satisfied that
you have enough information to answer all questions, prepare a multimedia
presentation to inform your classmates of what you have learned. Below
is a web site to get you started:

2.Replacement reactions are very important to our bodies, in the making
of plastics (polymers) and gasoline, and in keeping our surroundings and
us clean. Choose one of these areas, and conduct an Internet search. You
should look for answers to the following questions:
a.What are the reactants, and what are their chemical formulas?
b.What are the chemical formulas of the products?
c.How exothermic or endothermic is the reaction?
d.What is its importance? e.Is a catalyst used; if so, what is the catalyst
and why is it used?

Activity 10A – Use a word processing
program to set up the four-column table as directed in this activity.
Complete the first two columns by yourself and the third column with your
group. As you read the sections in the chapter, take your notes on the
computer. When you have completed the chapter, transfer your notes to
a presentation program and share with classmates what you have learned.
Print the document, and secure it in your SCIENCE PROBE Logbook.
