Life under a microscope

Without the invention of the microscope people wouldn’t know what was living or not living according to the “six characteristics of life”. We wouldn’t know what a cell was or what plant cells or animal cells were. We wouldn’t even know what our bodies look like or how they work on the inside. That means that we wouldn’t be able to fix our bodies either, if something is wrong. Because to fix something we have to know how it works and how it looks. Without the microscope we would not know what a bacteria was or how to stop it. We wouldn’t know which bacterias were good and which were bad.

Microscopes have helped us a lot with health and medical challenges. We wouldn’t know how to stop diseases or bacterias like we do today. Because of the microscope we learned that we have to wash our hands to stay healthy.  This is one of many examples of how the microscope has helped us live longer and healthier lives. Before the microscope was invented people got diseases and didn’t know how to cure them, but now, because of the microscope, we even have vaccines to prevent us from diseases. With the help from the microscope we know how the dangerous bacterias react, and that is why we know how to stop them.

What is life?

The characteristics of life are: Made up of cells, reproduce, respond to surroundings, grow and develop, energy, contain similar chemical

John’s parents should keep him on the machine till he starts showing progress and if he does not show any progress or if he gets worse they should take him off. And if the money gets a problem they can ask family members for help. The growing of his hair and nails shows that there is still life in him. Also that he swallows making gurgling noises, maybe he’s trying to talk.

I think the Socratic seminar was fun. I was an active listener and referred back to the text. I made comments that demonstrated good knowledge of the text, but I could have done more of it. I think I was a proficient critical thinker participant and I came prepared.

Semester 1 Reflection

  1. My highlights of Science 6 was the human water displacement tank, because I learned that our body has a particular and different volume than others and it was fun going inside. Another highlight was working with hat partners on the rock cycle simulation when we scraped the crayons and packed them in aluminum foil and burned them over the candle.

    2.  Something that was challenging for me was was choosing who to sit with because it distracted me                                from my learning.   

    3. My goals for Science 6 semester 2 is to do my homework quicker and properly and not hesitate with it. Another goal is to focus on my learning and make my vocabulary bigger. 

1906 San Francisco earthquake

  • When: April 18, 5:12 a.m. 1906
  • Where: San Francisco, North coast, Cenral coast, Northern California
  • Magnitude: 7.7 – 8.25 ~ 7.8 Mw[1]
  • Plates involved: Pacific plate and North American plate
  • Damage: 80% of San Francisco destroyed, 3000+ people died. 227,000-300,000 people were homeless, 28,000 buildings destroyed
  • Warning, aftershock: Quick warning for massive devastation

Unit 1 Reflection 

 
  

What are some things that you feel proud of learning in science class so far this year?

I feel proud of measuring with TBB and with rulers and meter sticks. I am also proud of finding the mass of  objects.

What are some challenges you have faced in science class so far this year?

I think some challenges for me is sometimes to measure volume and read the questions carefully on the tests.

What are some things you would like to improve upon? 

Some things I would like to improve on is to calculate between measuring units, (The King Henry slide).

How do you plan to do this? What help/ resources would you need?

To do this I’ll have to practice using the King Henry slide in my science notebook or in my iPad

Going through phases

What did you do?

We observed the different phases and collected data.

What tools did you use?
Thermometer, beaker, hot plate, safety googles, protection gloves, iPad.

What was the procedure for this investigation?
1: We put the icecubes in the beaker and placed it on the hot plate (hot plate was on 4)

2: We put the thermometer in the beaker and recorded temperature.

3: Every 4 minutes we recorded qualitative and quantitative data with the thermometer.

4: Slowly the icecubes turned into liquid, and then when we set the hot plate to its highest rate, the water turned  into gas.

What does the data tell you? Answer the questions in part A & B

A. Investigation part I (Solid – Liquid phase change)
How phases changes throughout a short activity.

When did you notice a change in temperature?

When the liquid turned into gas, the temperature got higher.

What did you observe about the temperature of the water over time once the ice was completely melted?

After the icecubes got melted, the water wasn’t as cold as the icecubes, so it was higher.

Why did the temperature of the water stop rising?

According to our data table, the temperature of the water continued rising.

B. Investigation part II (Liquid – Gas phase change)

1. What was added to the water in the beaker on the hot plate that caused the temperature to change?

We were adding heat to the water in the beaker to change the temperature.

2. Describe the temperature of the water while it was being heated to the point of evaporation.

The temperature got higher and higher and the water started bobbling.

3. Did the temperature reach boiling point before or after the water began to evaporate?
It reached boiling point before and while it began to evaporate.

Sources of error:

What are some reasons that your data/ results may not be accurate?
Some more thinking:
We may have seen wrong on the thermometer.

1. What if water only was in solid form? How would it effect our bodies?
Because our bodies contains liquid, it would be hard.

2. What if metals were only available in liquid form? How would if affect the way we travel?
It wouldn’t be possible to travel with car or plane or train or ships because all of them is made of metals. Then you would have to go by wooden boat or horse and carriage or just walk.
