1. Were the actual amounts of water very different from what you predicted? What was different?
The amounts were far from the actual amounts because we didn’t think about the ocean that it was pretty much the whole Earth.
2. What surprised you the most about the actual amounts of water?
I thought the lakes were the most because lakes are bigger than most of them but we forgot about ice.
3. What percentage on Earth is salt? What percentage of water on Earth is fresh? What implications does this hold for humans beings who consume fresh water?
There is 97% of salt water and 3% of fresh water. We should stop drinking too much water for no reason.

1 way I will research better by putting quotes and addition or subtraction signs. Another way I will research better by using information from different sites and using it in my search.
Annotations:
Article 1:
Our bodies can go 3 days without water before dehydrating.
There are many ways to disinfect water.
Water comes from freshwater sources, lakes, rivers, etc.
Snow that recently fell can be safe for drinking.
Boiling water can kill the bacteria for water to be safe to drink.
You can use the sun to kill bacteria in a water bottle.
Rain, hail and sleet are ways of drinking water.
You can put rocks in a fire for 30 minutes and put them in a container and they become a rock depression.
Some types of straws can filter out the bacteria in water. Have a pocket filter just in case if you need to filter water.
A very common tool is the disinfecting table, it disinfects the water.
Using household chemicals can disinfect the water.
You could drink water raw but it would be a gamble.

Article 2:
Pouring water through a towel is one of the most suitable ways to clean water.
Clay vessels is good for getting rid of mud in water. Using a water filter will purify water.
Purified water is harder to get every year. Gas hydrate crystals are formed by carbon dioxide when it is low.
UV (Ultraviolet) can be used to purify water.
Iodine most of the common pathogens in the water.
Microbes can be destroyed by the temperature of the sun.
You can get safe drinking water from unnatural sources using solar distillation.
A method that requires ozone (blue gas with a bitter smell) can be used to purify water.
You can sieve water that has been contaminated by leaves but cannot be used with raw water.
You can use a Jemping Stone Filter to filter out water without any cost.
Flocculation can filter high levels of contamination.
5-6% of chlorine can kill bacteria.

Our blueprint is a little bit similar to the bottom one because it uses pebbles, and has 3 layers.

Our filter works because once you drop the water onto the coffee filter it collects all of the bacteria. When the rest of the waters goes onto the second coffee filter the water will definitely be clean. The pebbles will also help the coffee filter collect all of the bacteria. While the water sorts itself through the pebbles it will filter itself and the bigger chunks of dirt will be stuck on the rocks. Then it will go through the coffee filter and the smaller chunks/bacteria will be collected, but still some pieces of bacteria will remain. The pond water will be purified after the coffee filter, there will be a straw with grains of rice. The gauze will be taped to the bottom so the rice will not fall out. After the water goes through the rice, the water will be purified. The structure is basically like one big tube that is made up of cups and paper cups. The material that we are using is a mixture of nature and house wash materials.

Mechanical filtration is the process of physically removing particles. It is the first stage of filtering water. It physically traps dead plant matter, uneaten food, and debris. It wastes matter from the aquarium water.

What can you observe in this picture? Do you know the concept of this system? What does this system do?
I think it is a cycle because it’s going into a filtration system then putting the clean water back in there and repeating. I think it helps the fish swim in clean water and when it’s dirty, it goes over again.
Aquaponics is the combination of aquaculture and hydroponics that grows fish and
plants together in one integrated system.
How are the fish and plants connected in the aquaponics system?
I think it is because fish and plants are in the water. The plants use the fishes water and it cleans the water for the fish and it repeats like a cycle.
Hydroponics – Plants are growing, growing with just water, no soil
Aquaculture – Breeding fish and taking care of fish
How are the two combined to make aquaponics?
The part of using fish and using plants for filtering water.
Research on the internet and find three advantages to using aquaponics.
Aquaponics saves us more water because it takes less water to use it.
It uses no soil
There cannot be any pesticides or herbicides

Aquaponics Homework
Aquaponics is a natural process. Aquaponics is aquaculture and hydroponics combined. The fish are raised in the tanks. It is a soil-free system for growing. The fish waste is a way for the plants to get it’s food. The food allows the plants to create a natural way to filter water. This makes a sustainable way for plants and fish to live.

Is an aquaponics system an ecosystem? Why or why not? Explain.
An aquaponics system is an ecosystem because it has biotic elements. An ecosystem is a natural system. It has abiotic factors.
The Aquaponics Systems
What is it?
Advantages
Disadvantages
Media Filled Grow Bed
Filled with gravel, rocks, media. Water is pumped over the beds to the plants.
Pots are easy to move or put in. Stable, support.
Have to move.
Raft
Floating device where plants hang their roots in the water.
Highly oxygenated. Uses less fertilizer. Low maintenance
It is difficult to maintain the temperature. It is hard to check on the roots.
Nutrient Film Technique (NFT)
Has channels, white rectangular, holds your plants. Sticks with the channel, has water running under it.
Plant roots are exposed to adequate supplies. Low water and nutrient consumption. Easy to disinfect roots.
It needs a reliable supply of water and power. Pump failure can result in death.

Describe the role of bacteria in the nitrogen cycle of an aquaponics system.
The fish produce ammonia (fish waste) and the nitrosomonas and it eats the ammonia. The nitrosomonas produces nitrites and the nitrobacter eat it. The nitrobacter produce nitrates and plants eat it. Then the fish eat it and it becomes a cycle.

Questions for aquaponics-
1: I don’t think it is ready since there is still a bit of ammonia and nitrite and the nitrate level isn’t as high as we wanted it, the pH is a bit over it.
2: It is important because if we monitor the water quality, we can check if it's clean all the time.
3: I think that it shows if the bacteria is doing a good job of eating what they need to in the nitrogen cycle.
4: We didn’t have as much nitrates as we wanted and see if we could lower the nitrites, I would use the water and see if it goes through all of the components in the nitrogen cycle.

-Water, nutrients, and oxygen goes through the roots
-The plants are grown in the channels then put back into the tank
-The aquaponics NFT is more organic and has living water
-Water flows nonstop through the fish tanks
-The organic and living water will clog in the pipes and tubes
-Flim water falls down the channels
-Less used method than other two

The cell is the basic structural, functional, and biological unit of all known living organisms.
A cell is the smallest unit of life that can replicate independently
Cells are often called the "building blocks of life“
Cells have some differences in plants and animals
Cells contain smaller structures called organelles
Organelles – organized or specialized structures within a living cell
1.Why did the website show the cell membrane as a gate?
Because it shows that it lets in certain materials.
2.What is the importance of a cell membrane?
Food, oxygen and water moves through it.
3.Do both plant and animal cells have cell membranes?
Video about cell wall:
http://study.com/academy/lesson/plant-cell-structures-the-cell-wall-and-central-vacuole.html
Yes.
1.How are plant cells different from other organisms cells?
Plant cells make photosynthesis and makes food
2.Why is the cell wall so important?
It provides strength, protection, and shape.
3.How is the structure of a cell wall related to its functions?
The cellulose provides the cell wall’s functions.

Elodea Plant Lab
What color were the Elodea cells?
What were the green bodies inside the Elodea cells?
Where were these green bodies mostly located?
Describe the shape of the chloroplasts.
Why are the chloroplasts green?
Were the chloroplasts stationary or moving around the cell? Why were they moving around?
Was there a large space inside the cell? What do you think it was?
What is the function of the central vacuole?
Describe what happened to the Elodea cells in the presence of 5% salt solution.
Describe what happened to the Elodea cells in the presence of 10% salt solution.
Why doesn’t the salt move into the cell, instead of water moving out of the cell? What does that tell you about the cell membrane?
What structure did the shrinking of the cell allow you to observe?
Predict what would happen if we used a 20% salt solution.
Describe what happened when you flushed out the salt solution with tap water.
From your observations, is Elodea a freshwater or saltwater plant?
The water in the cell is clear, that is what is making it clear.
The green bodies in the cells are chloroplasts.
The green bodies were located floating in the cell.
The shape of the chloroplast is a circle shape.
Chloroplasts are green because they have pigments that soak up wavelengths of light.
The chloroplasts were moving but they are normally still but they moved because the salt water was pushing them out.
I think there is space in the cell because the cell has many organelles in it like the chloroplasts and the nucleus.
The function of the central vacuole is to provide structure.
