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)



 
The total amount of energy in a closed system remains constant. Energy can be converted from one form to another, but it cannot be created or destroyed.

This week you are to explore the website below (click on the image below the assignment) and create closed circuits.  Try to create as many different possibilities as you can. 


Assignment...
  1. Describe in a 2 separate sentences 2 working circuits you created on the website, please include all parts of the complete circuit you used. (5 points each, 10 points total)
  2. Choose one of the circuits from above and explain how energy is changing forms in your circuit. one sentence (5 points)
  3. Please post in the comment section, answer should be at least 3 sentences.

Trace energy transformation in a simple closed system (e.g., a flashlight). Covered by Study Island Topic:
Energy Transformations
 
Assignment...For this post you are to comment about your experiment you completed (at home) on the topic you submitted below...If you did not complete an experiment...you are to go to the website link below this paragraph watch a few videos and comment on 3 facts you learned from the videos on matter and energy.

http://www.neok12.com/States-of-Matter.htm    Scroll down on page to find videos



For this week you can choose from one of the following topics to investigate...
1....Investigate how matter can change forms but the total amount of matter remains constant.

or

2....Describe how an object can have potential energy due to its position or chemical composition and can have kinetic energy due to its motion.


To investigate you are to design and create an experiment to demonstrate your chosen topic.  You can research to find appropriate experiments...All topics must be approved by me!

Part one of this assignment is to complete the form below describing your experiment.
 
Today you are to investigate one current news event.  For this you can either read an article from an online newspaper (links are below) or watch a video from a network news station (links below). 

Steps to complete your assignment:
  1. Find an article
  2. Read or watch the story
  3. Summarize the story in 4-6 sentences

Changes in Ecosystems can have both positive and negative effects on the environment.  Human effects such as polluting and habitat destruction can destroy entire ecosystems.  Other factors occurring in nature; such as forest fires and volcanoes effect ecosystems as well. 

Today's assignment:
  1. After reading the "changes in ecosystem" lesson in Study Island you are to select either a natural effect on ecosystems or a human effect on the ecosystem.
  2. Once selected, research a human documented example of this change in an ecosystem.  (for example, If i choose a human effect--->I might look up the gulf oil spill and research the effects this disaster had on the ecosystem.)
  3. List what you selected and write a brief description of the event. (when, where, and what happened)
  4. What wildlife/plants were effected by this.
  5. How was the overall ecosystem changed by this event.
  6. Post answer on this blog

 
Food Chains vs. Food Webs

This week you are to write and describe an example of a food web and a food chain and Post it in the comment section.  DO NOT USE THE EXAMPLE SHOWN IN STUDY ISLAND FOR THIS ASSIGNMENT!

Please respond following the guidelines below:
  1. Your first paragraph should include the definition of a food chain and an example of a food chain with at least 5 organisms.  Make sure you name the organism and explain who eats who in the chain.
  2. Your second paragraph should include the definition of a food web with at least 5 organisms.  Make sure you name the organisms and explain who eats who in the food web.
  3. This post should be two paragraphs and should take you no longer than 30 minutes.

 
Examine the types of relationships between organisms discussed in Study Island this week.  Symbiosis or Symbiotic Relationships are described as, "an interaction between individuals of different biological species. At least one of the organisms receives a benefit from the interaction."  After examining the chart below and watching the video provided please complete the following:

Please research to complete the following...Answers should be posted to this blog!

1. An example of a Commensalism Symbiotic Relationship found in nature...List the two species and include the benefit received by one species.

2. An example of a Mutualism Symbiotic Relationship found in nature...List the two species and include the benefit received by both species.

3. An example of a Paraistism Symbiotic Relationship found in nature...List the two species and include the benefit received by one species and the negative effect received by the other species.
