Boat test

We went to the lab. We had to make boats and had to put pennies in to the boat and we had to see when the boat sink. This is the picture bellow when we were making the boat 

After we made it, the boat was looking like this in the water

And we had 183 pennies in the boat. 

It's Interm Report Time!

1. Work Habits:  Attendance - how many classes have you missed?  Why?  Do you come to class on time?  Do you come to class prepared?  Do you make good use of your class time?   Are you following the safety rules in the lab?
Ans. I missed 3 classes. I always come to class on time. I listen to the teacher all the time. I did everything completely. I always follow the safety rules, especially when I go to the lab. I always wear glasses.

2.Assignment completion:  How many assignments have you completed?  What assignments are you missing?  Why?  Have you included your blog assignments in your totals? 

Ans. I have completed every assignments. I also completed my every blog post. My current grade is 88%. 

3. What has been the most challenging assignment so far?  Why?

Ans. Until now I did everything perfectly, but the video assignment was little bit hard but I did it and i completed the project.

4.Assignment quality:  Are you showing your learning in your assignments?  Are you completing them to the best of your ability? 

What assignment/post are you most proud of so far in this course?  Why?

Ans. I'm showing learning assignment through writing skills. Yes I'm completing them to the best of my ability.

Based on my reflection/work/progress so far in Science and Tech is Good.

Ocean Acidification

1. What is ocean acidification?
Ans. The process of ocean acidification is surprisingly simple. Carbon dioxide from the burning of fossil fuels accumulates in the atmosphere, where it cause global warming. But it also affects our oceans. Ocean acidification refers to a reduction in pH os the ocean over an extended period time, caused primary by uptake of carbon dioxide (CO2) from the atmosphere.

2. What human activities have caused this problem?
Ans. Human impact on the environment includes on biophysical environmenta and other resources. The term anthropogenic designates an effect or ovject resulting from the human activity.

3. How much has the acidity of the ocean changed?
Ans. As long as there is carbon dioxide in the air the ocean will continue to become more acidic.

4. How does the increased acidity affect animals in the ocean?
Ans. A lot of the fishes and sea creatures are going to extinced, because of the carbon dioxide.

5. How are pink salmon affected?
Ans. The climate change and prove that the oceans are more acidic than ever now. The 15% water imperative increase.

6. How are coal reefs affected?
Ans. Human activities thay reater the coal reeks in many ways corel from US the human variable seasons serve stroms

7. How might ocean acidification affect you?
Ans. Ocean acidification affects US in many reasons some of the things that we drink comes from the ocean.

8. What can you do to decrease CO2 eemissions?
Ans. We can decrease CO2 not that alone because there are 7.8 billion people on this planet and everyone contributes to the pollution of the populations.

Acid Base Neutralization Lab [Part - 2]

In part two {Buffere}

pH paper turned into pink and yellow with the different chemicals. 

Acid Base Neutralization Lab [Part - 1]

First part 

We created neutralization reaction with different concentrations of Hydrochloric acid [HCL] and sodium hydroxide [NaOH] and tested the pH paper. We came up with 5 different colours.

Part second 

In the second part we put cabbage juice into those test tubes to change their colour to purple. 

Third part 

As you can see in the first picture every test tube was in a different coulour. But with the cabbage juice those test tubes turned to kind of purple colour. 

HCL 1.0m was the stronger acid. 

NaOH 1.0m was the stronger bace.
