Today is May 4, 2016.

The homework due for the week of May 9 is posted as follows:

Take the article, "Introduction to Climate Change".  There are 17 paragraphs in the article.  As if you are the teacher of a classroom, make up one question for each paragraph.  There should be 17 questions total.  Please submit the homework in the basket.  I don't always make the announcement to collect homework.  Please take the initiative to hand it in.  I do look at all the work submitted at the end of the day, and will look for your homework to grade.  Thanks!  -Ms. Yoon-

Homework   Due on the Week of March 14

(In celebration of Women’s History Month)

In the past, women were being looked down on, and not given the recognition that they are capable to succeed.  It is possible that this type of bias is still taking place today.    

Pick a female scientist.  Pretend that she is a good friend who is writing a letter to you.  ==================================================================

In the letter, include the following:

Ø  A challenge that your friend (the female scientist you picked) must have experienced to succeed.  (This part is made up based on what you believe must have happened)

Ø  How your friend overcame the challenge.  (Example:  her dedication and commitment)

Ø  The discovery made by your friend.  (Include her joy and pride) 

Ecosystem (Relationships between living and non-living things) 
Q1) Define, “Food web” and “ecosystem”. Food web: _____is the visual diagram on "what eats what" Ecosystem: is the visual diagram on "what eats what". 
 Q2) Where in the food web do you usually find the plants? _____At the bottom__ 
Q3) Why does it make sense that the animals are found at the middle and the upper part of the food web? They cannot make their own food
 Q4) Why does it make sense that plants are called, ‘producers’? They produce or make their own food. 
Q5) Why does it make sense to call the animals, ‘consumers’? They have to work for their food. 
Q6) Define, “primary consumers”: _____Animals who only eat plants_____________ 
Q7) What other name is given for the primary consumers? _______Herbivores__________ 
Q8) Define, “secondary consumers”: _____________Animals who eat other animals
 Q9) What other name is given for the secondary consumers? ____Carnivores____________ Q10) Define, “omnivores”: ____Animals who eat both plants and meat_____ 
Q11) Which category do you fit in?____Answers vary_________________________________ 
Q11a) Explain why you would place yourself in such category.  Answers vary
Q12) What part of the food web will you find producers?  At the bottom
 Q13) What part of the food web will you find primary consumers? Middle______________ Q14) What part of the food web will you find secondary consumers? _____Top____________ Q15) What does the “arrow” in the food web symbolize? Arrow points to the one that is doing the eating. 
 Q16) A bird from South America is accidentally released into the community. This bird is excellent at hunting spiders. What will happen to the local populations of insectivorous birds (birds who eat insects)? Insectivorous (insect eating) birds eat spiders for food. If spiders get eaten by the other bird, the number of insectivorous bird will decrease (get smaller). 
 Q17) A viral infection (sickness) destroys the fox population. Explain how will this affect the hawk population? Hawks and foxes compete (fight) for the same foods. If foxes decrease in their number, hawks will have more foods to eat and will increase (get larger) in their population (number). 
 Q18) Due to weather changes, the populations of predaceous insects (insects that eat other insects) migrates (move) to a different habitat (location). Explain how this will affect the plant population. Predacious insects eat herbivorous insects. Herbivorous insects eat plants. If the populations of predacious insects decrease, the number of herbivorous insects increase, and the population of plants will decrease as the herbivorous insects will start eating up more of the plants.
 19) Drought leads to reduction of plants. Explain how this can affect the entire food web. The decrease in the populations of plants be a disaster for the whole animals of food web. The 1st level of consumers depend (need) plants as their food. The 2nd level of consumers depend on plants as their food.

Homework Due on the Week of March 1st, 2016 Photosynthesis in Our Lives You need to write 3 paragraphs analyzing the topic on Photosynthesis. Please use the note we have completed (finished) during our class discussion. Paragraph 1 Talk (write) about your favorite fruits and vegetables. What make these foods your favorites? How nutritious are they? What kind of vitamins do they have? How do they help you grow and stay healthy? Paragraph 2 These fruits and vegetables that are your favorites come from plants. Now, write about how plants grow. Describe what they need to grow to produce such delicious (tasty) and healthy foods for you. Here mention the Photosynthesis process. How do they get glucose (sugar)? How is this glucose important to us and to plants? What else do plants produce to help us survive? Paragraph 3 Discuss two step process in Photosynthesis as we discussed in the note. Why is the 1st step called ‘light reaction’ and the 2nd step called ‘dark reaction’? Why is the 2nd step also called ‘Calvin Cycle’? Who is Calvin?

Energy in Everyday Life Q1) Where do you get your energy? Food Q2) Where do birds and squirrels living outside in our neighborhood get their energy? Insects and nuts Q3) Explain why this statement is true: “All the energy starts from the sun.” Sun gives energy to plants to grow. Animals including humans eat plants. Q4) What is the process where plants take the sunlight and change it into energy? Photosynthesis Q5) What other two types of organisms also can change sunlight into their own energy? Bacteria and algae Q6) Where does the energy for life come from? __________Sun_______ Q7) In addition to foods, what other resource (material) do plants give us and other living things to live? _______Oxygen________ Q8) In photosynthesis, the reactants are: _____Water______, _Carbon Dioxide________ and the products are: _____Oxygen_____________________, ___________Glucose (sugar)________ Q9) Glucose is sugar that has the chemical formula of: ____C6H12O6_________ Q10) What chemical is not part of the photosynthesis process? __________Carbon Monoxide______ Q11) What is one thing do you remember about ‘cells’? Cells are small things that make up all living things. Q12) What structures do you find inside of every cell? ____Organelles_______ Q13) What particular organelle will we be focusing on for the study of photosynthesis? _____Chloroplast______ Q14) What organelle found in the leaf cells does photosynthesis take place? Chloroplast Q15) What is the job of the chlorophyll found in the chloroplast? Chlorophyll capture sunlight Q16) How do plants take in the two reactants, water and carbon dioxide? Take in water through roots. Take in carbon dioxide through stomata. Stomata are holes found underneath leaves. Q17) Which of the following are used in Photosynthesis? (3 answers) Water, sun and carbon dioxide Q18) Which plant parts are used in the collection of raw materials for photosynthesis? ______roots and stomata (found in leaves)___ Q19) Which step collects the raw materials? ____Step 1____ Q20) In which step does the chemical reaction take place to produce glucose (sugar) and oxygen? _______Step 2_____ Q21) Why is the Step 2 called, ‘dark reaction’? It does not need sunlight to work. Q22) Why is the second process (dark reaction) in Photosynthesis also called the Calvin Cycle? Dr. Calvin discovered the second step of the photosynthesis Q23) What is the name of the cycle that is also known as the light independent reactions? ___Calvin Cycle__ Q24) Why is Calvin Cycle also called dark reactions? It does not need sunlight to work Q25) What is the chemical equation for the photosynthesis? Carbon dioxide + Water  Oxygen + glucose (sugar) Q26) What are two products of photosynthesis? Oxygen and glucose
