Technology is the application of scientific principles to solve problems and accomplish tasks. Technological design is the process of finding the best solution for a problem that is also within the given constraints.

Over the past 100 years technology has helped shape our lives more than ever.  For today I want you to explore the  website links below and discover what are thought to be the most influential inventions of the past 600 years.

Top inventions of the past 100 years
Inventions of each century

Assinment...

1. List 10 influential inventions of the last 600 year, 5 from the past 100 years and 5 from prior to that.  Include the year of each discovery (10 points)
2. Select 2 of the inventions listed in question 1 and in detail describe what impact each discovery/invention has had on society and who invented it (5 points)

Technology is the use of knowledge, tools, and materials to solve problems and accomplish tasks. Technology can have both helpful and harmful effects.

This Week finish all assignments in Section 4. in Study Island.  Once finished play review games to help you study for next Week.

Next Week we will take a comprehensive assessment over this section.  This will count for a grade so make sure you Review. 

Take your time on the review games and answer them correctly.

Mr. Reese

A wave is a moving disturbance that transfers energy through matter or space.

Investigate the wave simulator below....

....answer the following questions in the blog section...

1. Set the wave simulator to "oscillate" and "no end"
2. What happens to the waves when you increase amplitude?
3. What happens to the waves when you decrease amplitude?
4. What happens to the waves when you increase frequency?
5. What happens to the waves when you decrease frequency?
6. Notice that the dots on the wave go up and down while staying somewhat in place...explain why this happens...make sure you use what you know about energy waves to answer.
   

Energy can be transformed, or changed, from one form to another.

Assignment...Post in the comment section
1.  Provide an example of chemical energy transforming.
2.  Provide an example of the Sun's nuclear  energy transforming.
3.  Provide an example of thermal or heat energy transforming.
4.  Provide an example of potential energy transforming to kinetic energy.

Energy comes in many different forms....

Assignment...

1. List the 7 types of energy listed on page 1 in study island.
2. Complete the simulation below...as you change the variables for the skater what happens to the amount of energy used? 
   
3. Explain what the Law of Conservation of Energy is.
   

Humans depend on energy for many activities every day. There are many different ways of obtaining, transforming, and distributing this energy, each of which has different environmental consequences.

Assignment...answer the following in the comment section...

1. Select an energy source (renewable or nonrenewable) and make a case or argue why it is the best source of energy for people to use.  Include at least five facts about the energy source (for example, location, how abundant it is, is it renewable/nonrenewable, cost, and so on...). 
   
2. Include at least on professional source other than study island with your answer....no Wikipedia this time, fine a credible website dedicated to your energy source....copy and paste the web address in your post.
