Chimacum Creek


 We are Chimacum Elementary 6th grade students and we test the water quality of Chimacum Creek every year to see how it’s doing. My claim is that Chimacum Creek is doing well.

My evidence comes from six water quality parameters. The dissolved oxygen in our creek has gone from mostly 7 mg/L to 8 mg/L. Salmon and trout need a minimum of 6 to 7 mg/L so they have enough D.O. Salmon and trout live in freshwater with slightly acidic pH, which is less than 7. Our creek has gone from 6.1 to 6.7, which is within that range. Salmon and trout have an optimal stream temperature of 54 degrees Fahrenheit and our creek has a range of 39 degrees F to 60 degrees F in the fall, early winter, and spring and that is well within the range needed by the fish. Salmon and trout returning to lay eggs need colder water, about 39 degrees, and the eggs need the water to be from 39 degrees to 44 degrees F and that is exactly what we’ve gotten in the winter. Our creek water is very clear, the turbidity ranges from 0 to 63.7 NTU and that is very clear water. 

From the conductivity we can tell that our creek is within the correct range of salts for freshwater so that is good. The final parameter we measured is the flow rate and from the flow rate we calculated the stream flow which was on average about 135 gal/s this year. We have had a few years of heavy water flow from lots of rain, as high as 3400 gal/s, and years of low flow, as low as 54 gal/s, and since the fish are returning year after as shown by our fish trapping fish counts, we can conclude that the flow has been within an acceptable range for our fish to survive.

I think this happened because our community and the farms in the Chimacum Valley are doing a great job of not polluting our creek. My data support my claim because all six parameters are well within the range of what our fish need and neither the pH nor the conductivity point to any pollution in our creek.

The Measles

What it is:

The measles is an infectious disease that is also highly contagious caused by a virus. Measles is one of the most contagious diseases! If one person has measles, 9 out of every 10 people that person comes into contact with will get measles! Measles is now under control thanks to the measles vaccine but it used to be a serious problem. Measles epidemics would cause outbreaks every two to three years and cause 2.6 million deaths per year! Measles infections among children used to be very common.

Measles is very contagious and is spread through the air when infected people cough, sneeze, or talk. When they cough, sneeze, or talk, people put droplets of aerosolized liquid infected with the virus into the air. The virus floats in the air and non-infected people can breathe it and become infected. The virus can also survive for hours on surfaces so even after the infected person has left an area, virus on surface can infect people who touch those surfaces and then touch their eyes, nose, or mouth. The measles virus incubates and replicates in the nose and throat of people and will become full measles within 10 to 14 days. Four days before the rash appears and four days with rash, infected people can spread the virus to others.

The symptoms of measles include:

  • the first sign is a high fever, usually 10 to 12 days after infection
  • rash made of large, flat blotches
  • dry cough
  • runny nose
  • sore throat
  • tiny white spots inside the mouth
  • mild pink eye
Sometimes measles can even lead to the following symptoms:

  • Ear infections
  • Diarrhea (watery poop)
  • Pneumonia (lung infection)
  • Bronchitis (another lung infection)
  • Inflammation of the brain (encephalitis)

Pathogen:

Here are two pictures of the measles virus, also known as rubeola:

Because the measles pathogen is a virus, therefore not a living thing, antibiotics do not destroy the virus. If antibiotics are prescribed to people infected with the measles it will be to kill other bacterial infections that are caused by the measles disease such as eye infections, ear infections, and pneumonia.

Treatment:

There is no treatment for the actual measles disease. What can be done is to care for the sick person until their body can develop antibodies to fight off the virus. Caring for people with measles includes making sure they get good, healthy food and that they stay hydrated all while resting. 

Instead of treating the disease, the best course of action is to prevent children from ever getting the disease by getting the MMR vaccine. To keep children from getting measles from the rubeola virus, they should get all their measles vaccines. Vaccines put weakened viruses into your body so that your immune system can develop antibodies and antigens also with your immune memory cells so that if you do get the full rubeola virus, your body can tag it and destroy it before you get the measles disease!

Heat Energy in Water

Intro: 

We put ice water into glass beakers and plastic beakers. The ice water was about 40 degrees F. We also put hot water in glass and plastic beakers. The hot water was about 140 degrees F. We collected temperature data with a temperature sensor for five minutes straight.

Claim: 

Ice water does not change temperature very much after five minutes of just sitting there while hot water changes temperature a lot more in five minutes of just sitting there.

Evidence: 

Using glass and plastic beakers ice water only changed about five degrees F in five minutes. While hot water in both glass and plastic beakers dropped about 45 degrees F in five minutes!

Reasoning: 

We noticed that the ice water still had ice in it after five minutes of data collection. That means that the water still had to be cold, which explains why the ice water did NOT increase in temperature very much. The hot water lost over 45 degrees F in five minutes because it transferred more heat to the classroom. Our data supports my claim because the ice water, whether in a glass beaker or a plastic beaker barely changed temperature in five minutes, five degrees F on average, while the hot water, whether in a glass beaker or plastic beaker, lost about 45 degrees F in five minutes.
