No Journal Assignment this week...Make sure you complete the assignment in study island.
 
 
_Matter can undergo physical and chemical changes. When a physical change occurs, a substance changes without altering its composition. When a chemical change occurs, a substance has chemically reacted to form one or more different substances.

Assignment....
  1. Complete the Changes Online LAB  (click on lab to use the link then click on run module)
  2. Post in the comment section 3 examples of Physical Changes AND 3 examples of Chemical Changes
  3. Explain the Law of Conservation of Matter (can be found on page 2 of study island lesson)
 
 
_Matter on Earth is generally found in one of three different states: solid, liquid, or gas. Another common state of matter that is much more rare on earth is plasma. The state of matter that a substance has depends on the arrangement of the particles, the attractions between particles, and the amount of energy the particles possess.

Assignment...Only 1 question this week, be complete and detailed.

1.  Using water as an example, in one paragraph describe the list the three phases of matter that water exhibits, how it changes from one phase to the other and whether or not the mass of the matter changes as it goes from phase to phase. 


 
 
Assignment...In the comment section answer the following...
  1. What is the difference between adaptation and extinction?
  2. What are two ways mentioned in the study island lesson that Humans impact the environment (found on page 2)
  3. List the three natural processes in which the environment changes. (page 1)
  4. Look up (research) and list 3 animals that have gone extinct in the past 100 years due to human impact on the environment.  
Below is a video on extinction, it is an hour long and the quality isn't perfect but there is a lot of good info!  Enjoy
 
 
Some organisms have favorable traits that are well-suited to their immediate environment. Organisms with this advantage are more likely to thrive, reproduce, and pass their traits to future generations than organisms without those favorable traits. This process is known as natural selection.

Watch the video below and notice a few examples describing natural selection.  This theory suggests that all organisms are related to each other if you go back far enough in time.   

After watching the video please see the assignment below...

Assignment....to be completed in the comment section....
  1. Define and provide and example of an adaptation
  2. What is a mutation and how can they benefit organisms.


 
 
The ultimate source of energy for all ecosystems is the Sun. Only producers can convert solar energy into food energy. Therefore, all other organisms depend on producers for their energy needs.

Food Chains vs. Food Webs

Assignment.....

  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. (7.5 Points)
  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.  (7.5 Points)
  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. (5 points)

2. An example of a Mutualism Symbiotic Relationship found in nature...List the two species and include the benefit received by both species. (5 points)

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. (5 points)

Standard OH Grade 6-8, Science Standard Life Sciences C Explain how energy entering the ecosystems as sunlight supports the life of organisms through photosynthesis and the transfer of energy through the interactions of organisms and the environment.

 
 
Life is very diverse and living things come in all shapes and sizes.  For this week research different types of living things and write about them. 

Step by step directions:
  1. Look up two types of plants; one example of a vascular plant and one example of a non-vascular plant.  Please write their scientific name (genus and species) and provide a brief description of them. (5 points)
  2. Look up two types of animals; one example of a vertebrate and one example of an invertebrate.  Please write their scientific name (genus and species) and provide a brief description of them. (5 points)
  3. Look up one example of a single cellular organism and one example of a multi-cellular organism (you can use one of your examples from above if you want.  Write a brief description and their scientific name. (5 points)
 
 
Features of an offspring that result from genes passed on by parents are called traits

Behavior is usually determined partially by heredity and partially by experience. Behaviors determined by genetics are inherited. Behaviors determined by experience are learned.

Assignment...
  1. List two inherited traits that you received from your parents.
  2. List two of your  learned characteristics 
  3. List two inherited behaviors
  4. List two of your learned behaviors
 
 
Reproduction is the process through which organisms create offspring that contain all or part of the parents' genetic material. The ability to reproduce is necessary for the survival of a species.

Assignment...
  1. What are the 5 ways listed in Study Island in which organisms reproduce asexually? (5 points)
  2. In 2 complete sentences, What are two advantages of asexually reproduction? (5 points)
  3. In 2 complete sentences, What are two advantages of sexual reproduction? (5 points)
