Science 7 – Biome Study Sheet

Test – Wednesday, November 4^th

Vocabulary from Science Probe

As you read through or skim the chapters, stop when you come across one of these bolded terms.  Either write the definition given in the paragraph or look it up in the glossary in the back of the book. 

(You will need to match the term to the definition on the test)  

1.  ecosystem	-habitat where organisms interact
2.  biome	- similar ecosystems throughout the world grouped together
3.  predator	-an organism that hunts, kills and eats another organism
4 . prey	- an organism that is hunted for food
5.  species	-a term to describe each different organism
6.  population	-all the members of one species living in a specific area
7. community	-a group that is made up of two or more populations of different species
8.  producer	-an organism that can make its own food from non-living materials   Eg. Plants – photosynthesis
9. consumer	-an organism that must get its food from eating other organisms (There are 3 types of consumers)
10. omnivore	-a consumer that eats both plants and animals
11. herbivore	-a consumer that eats only plants
12. carnivore	-a consumer that eats other animals
13.  detritivore/decomposer	-an organism that gets its food energy by breaking down dead organisms (detritivores actually eat it, decomposers secrete enzymes) Eg. fungi (decomposer) earthworm (detritivore)
14.  stewardship	-how the gifts that God has given to us are used and cared for eg. the environment
15.  biosphere	-the parts of Earth where life can be found

 Video Notes - These will be fill in the blank on the test.

1. Photosynthesis is the process by which a plant takes in the sun’s rays and converts it to the food it needs.

2. Abiotic refers to the non-living things that affect environment such as wind, temperature, sunlight.

3. Biotic refers to the living things that affect an environment such as birds, animals, plants.

4. Symbiosis is the close relationship that exists between individual organisms of different species.

5. Mutualism is a relationship where both species benefit eg. orchids and insects– the colour and fragrance attract insects who get pollen and nectar for food and then transfer pollen which then spreads the pollen that helps the orchids.

6. Commensalism is an association between two organisms in which one benefits and the other is unaffected eg. Nesting robins.  They live in the trees that remain unaffected.

7. Parasitism is a relationship where one species benefits and the other is harmed.  Eg. aphids and plants – the aphids eat the plants and inject them with a substance that can cause the plant to shrivel and die.

8. A food chain is the transfer of energy from plant to animal to animal.

9. A food web is interchanging food chains.

10.  Leaves change colour in the fall due to a decrease in hours of sunlight and a decrease in temperature. 

Biome Project Presentations - Short Answer Questions

Mountains	Tundra	Oceans	Savanna
Where is Mount Everest located? It is located in the Himalayas mountain range on the border of Nepal and Tibet (China).	Where do you find the tundra biome? (Arctic and Antarctica)	What is the Mariana Trench and where can it be found? It is the deepest part of the earth's oceans, and the deepest location of the earth itself. It is in the Pacific Ocean.	Where do you find the savanna biome? There are savanna's located in Africa, South America, India, and Australia.
What are the average temperatures in Mount Everest?  It fluctuates between -20ºC during summer and -35ºC in winter.	Why is hypothermia a danger to humans in the tundra? Hypothermia is a potentially dangerous drop in body temperature usually caused by prolonged exposure to cold temperatures and the average temperature in the arctic tundra is-34 degrees Celsius.	Name a predator that would be at the top of the food chain in the ocean? (shark or killer whale)	Name a herbivore that would be found in the savanna. (Buffalo, wildebeest, zebra, rhinos, giraffes, elephants and warthogs)

Rainforests	Deserts
Are rainforests in danger? (Yes, an area of a rainforest the size of a football field is being lost every second)	What is the name of the largest cold desert in the world? ( the Antarctic desert)
What is an example of an omnivore in the rainforest? (monkeys, tree frogs and birds)	What is the name of the largest hot desert in the world? (the Sahara)

Paragraph Response 

(approximately 100 words)

Name some ways that we, as stewards of this Earth God has given us, can better preserve, conserve and restore our planet.  You can discuss this issue on a global scale or very specifically to your own neighbourhood. 

Wrapping up Science Unit on Biomes

Hey Guys, 

Can you believe we have actually almost finished an entire unit in Science?  Your presentations were really good and I know you learned a lot about the specific biome you researched and also a few interesting tidbits from the other groups as well.  

Now, it is time to assimilate (take in and understand fully) the information from the beginning to the end.  Here is a brief review of what we have done: 

1.  Watched some awesome video clips with interactive notes to get us into the sights and sounds of ecosystems.  

*(living (biotic) vs. non-living (abiotic) environments)

* (why leaves change colour in the fall) 

* (herbivores, carnivores and omnivores)

* (food chains and food webs) Kratt Brothers

2. Researched our biomes and presented information on:

* where the biome could be found on earth

* what the climate is like

* an example of a food web or chain

* how it has changed and whether it was in any danger now or predicted for the future

Now it is time to take that Science textbook off the shelf and look into it.  We have basically covered the material in the first 87 pages by doing those first 2 activities, but let’s use it to review and to add to our knowledge. 

Please read or skim read those 87 pages (don’t panic, there are lots of pictures and labs you can skip) and fill in the study sheet with definitions for the terms you need to know for the test on Wednesday, Nov. 4^th. 

Homework Sheet for Oct. 26th to Oct. 30th

Grade 7 Homework

Monday, Oct. 26^th to Friday, Oct. 30^th

Announcements: Government Inspectors will be on campus this week so everyone, please be on your best behavior! 

Relate Youth:  Supper at the Robideau house and then over to the church for some fun.  There will be food, games and some costume fun.  

Credit Auction on Friday:  We could use a few more donated items from parents.  Chocolate, candy, gift cards, knick-knacks – anything is appreciated. 

Student Government is sponsoring a "Teacher Treat" Day in which students come dressed in costumes and the teachers will give them treats.  Stay posted for more information from the council and specifically our grade 7 rep, Rachel Schlosser. 

Weekly Challenge:  How did you do with getting at least 2 servings of fruit each day?  This week we are going to focus on an academic discipline – READING!  The requirement is to read for 20 minutes outside of class time (lunch and recess count).  As viewed in the movie, “Nightjohn”, learning to read was so important that some slaves would risk their very lives to teach others.  This quotation, accredited to the author, Mark Twain, says it all:  “A person who won’t read has no advantage over one who can’t.” 

Bible Memory:  Due on Friday, Oct. 30^th

Romans 8:1,2 Therefore, there is now no condemnation for those who are in Christ Jesus,  because through Christ Jesus the law of the Spirit who gives life has set you free from the law of sin and death.

English:  Underground to Canada - Chapters 5 -8 due Monday, Nov. 2^nd

 

Science:  We have seen all the presentations and they were really well done!  We will spend some time this week reviewing and preparing for a Biomes Unit Test next Wednesday, Nov. 4^th. A study sheet will be available on the blog and sent home in hard copy by this Wednesday.

Geocaching Field Trip:  Unfortunately the weather is too wet for us to go this afternoon.  We will go either tomorrow, Wednesday or Friday depending on the weather.  We will carry on with Science Project Presentations in its place this afternoon.  

Relate Youth - Small Groups this week.  No supper at the Robideaus.  Boys meet at the church and girls at Mrs. Robideau's house at 7:00.
