Reflection/Synthesis Questions:

Why is it important to use models when explaining or teaching things?
What are some limitations of models? (What makes them imperfect?)
How did you decide on the model that you chose for this video? What made it the best model for the job? (Why didn't you choose a different model?)

It is important to use models to make it clearer to someone. It makes them understand better with a visual.
The limitations of models would be the size. If its too big it wouldn't help.
The balls were best for this because you could

Where do you think the items came from originally?
Do you think the items look the same today as they did a month ago?
What happened to the matter in each item over the past month?
Do you think the items will be the same forever? Why or why not?
What do all of the items in the bag have in common?
Do you notice any relationships between the items in the bags? They all...
What evidence do you have that the items were all once part of a living thing?
Another name for "nature's waste" is "organic remains." These are all organisms that are no longer living, or parts of organisms that are discarded, excreted, or no longer needed. What other examples of organic remains can you think of?
What would happen to each item from your bag if it were left outside? What might it look like in 6 months? What would cause it to change?
What would eventually happen to the waste MATTER in each type of organic remain?
Why isn't the earth just piled up with all the matter from nature's waste?
Why could all of the items in the mystery bags be classified as nature's waste?
Do you think that all living things generate waste? What makes you think that?

Answers:

.Grass comes from ground, sticks come from trees, helicopters come from maple trees,woodchips come from trees, Flowers came from a flower, Pine needles came from pine trees.
Some of them because some decayed and some haven't yet. Thats why only some look the same as before.
It started to decay from not being alive after that time. It was decaying because it was dead.
No some will decay faster than others but they will all decay eventually.They decay when they die.
They are made out of matter. They were all alive at one point in time.
They all come from a plant (except for the bug). They will all decay.
They will all decay and I have seen them on plants.
Feces from animals and bugs. Another thing is soil which is everything that decays.
In 6 months would've rotten and decayed and look like a rotted twig.
It would turn into soil. It would turn into soil when it decayed over time.
Because it turns into dirt after decaying.
Because they were all living at one point
Because everything either drops things it doesn't need or releases solid or liquid waste that is living.

Reflection/Synthesis:

What are you trying to explain in your investigation?
What is your investigative question?

Answers:

Why dead things rot or decay.

Answer the following questions while analyzing the Nutrition Labels:

As a result of looking at food labels, what did you learn about food?
Look at the ingredients of one human food label. Write down the food name. What ingredients came from animals?
What ingredients in the above food label came from plants?
What similarities and differences did you notice between the human food and pet food labels you looked at?
Choose an animal/insect from the ecosystem walk. What do you think it eats? Explain what you think it gets from its food.

Reflect & Synthesize:
Answer the following questions in your blog post. Remember to have at least one follow-up sentence for each question, when possible.

What does food provide to animals, including humans?
Do the pet food and human food have the same nutrients? In what ways are they different?
Does a higher calorie count mean a food is better for pets to eat? What makes pet owners think that?
What is it in food that helps us repair our bodies and grow?
What in food helps us move and stay warm?
In what way does energy transfer when animals eat food?
Look at the nutrition label below for milk. How much energy is in the food?
What matter is in the food?

Answers:

That it tricks you into thinking it is healthy. It tricks you by telling how much per serving not per can.
In butter it has sweet cream and milk.

The ingredient that came from plants is canola oil.
A similarity is that that they both have calories. A difference is that in pet food it does not show the calories per serving.
I think Preying Mantis eats other bugs because it is higher on the food chain. I think that it gets energy and matter from the food.

Answers:

Food provides energy and matter to humans and animals.
No, pet food and human food do not have the same nutrients. They are different because other animals need other types of nutrients. A difference is the type of fat. In the human food it shows the types of fat, in the pet food it does not.
It depends. If the pet is not getting enough calories, it should have pet food that has higher calories. If it's getting too much, then it should have less calories. Pet owners thing higher calories is better because it will usually have more protein and fat.
Protein is what is in food that helps us repair our bodies and grow.
Energy is in food that keeps our bodies warm.
Energy transfers into heat in their bodies.
160 calories is in the milk. Calories is a way to measure energy.
Fat, nutrients and protein are the types of matter in food.

Reflection/Synthesis:
Answer the following questions in your blog post. Remember to have at least one follow-up sentence for each question, when possible.

Plants need energy and matter to grow. Where do plants get their ENERGY?
Where do plants get their MATTER?
Where do plants get their FOOD (be careful - this is a trick question)?
Why are plants called Producers?
What would happen if plants didn't have a way to get energy?
What would happen to animals if there were no plants to eat?
What are some of the LIVING components of a plant "system"? (A plant "system" is everything that a plant needs to survive and everything it produces.)
What are some of the NON-LIVING components of a plant "system"?
In what ways do the components of the system interact?
What matter is transported in and out of the plant system?

Answers:

From the air and soil. They use carbon for energy.
From the carbon in the air. they breathe it and o2 is there waste.
Plants are producers, they don't eat food. They still get matter.
Because they make there own food. They produce there own food.
There seed will provide for them until its out of energy and then it dies.
Everything would die. There would be no food.
One part is photosynthesis which makes them grow.
The soil helps it grow by keeping it grounded.
The sun provides light for photosynthesis for them to grow.
Air and oxygen.

Reflect & Synthesize:
Answer the following questions in your blog post. Remember to have at least one follow-up sentence for each question, when possible.

Choose one of your Food Chains that you created and explain how it works.
Can a Food Web be considered a "system"? Why or why not?
What happens if a plant or animal all of a sudden disappears from the food web?
Using this food chain, "sunlight to apple to worm to bird to cat," How do organisms in this food chain get the matter they need for body repair and growth?
Using the same food chain in #4, How do organisms in that food chain get the energy they need for body warmth and motion?
What do you think happens to the matter that is NOT used by the organisms in a food chain or food web? Is it wasted or does something else happen?

Answers:

I made an ocean ecosystem. It works by an animal eating another animal.
I made an ocean ecosystem that starts at Phytoplankton and zooplankton. then it moves up to actual fish which are a small fish a larger fish and then a shark.
If 1 If one animal goes missing it will mess up the entire Food chain.That means that if one animal goes missing it will offset the balance. In a food chain if 1 animal goes missing that means one animal will go hungry and another animal will go hungry because it disappeared which keeps going on until the food chain end.
What happens is the sunlight is creating photosynthesis for the plant or Apple. The worm will eat the apple. The bird will eat the worm and then the cat will eat the bird and slowly the calories will decrease by a certain amount that's why some animals have to eat more and that's why is you keep moving up the food chain and there's less and less of them.
In the food chain the animals got there heat and energy through eating the matter. The reason they're getting the matter is because they are eating more matter which is giving them more matter.
The matter not used will be decomposed by decomposers. Some of those decomposers are mushrooms are fungi. the matter will not disappear though because matter can never disappear only change form.
