Examining different cells such as the plants, animal, and fungus cells. Identify the different organelles found in different cells and list the organelles and structures the characterize each of them.

Answer: Organelle is a sub-unit of cell and it is involved in performing specialized function within the cell. The type of organelles vary from organisms to organisms.

Explanation:

1. Centrioles are the cell organelles in which the spindle fibers are organized to which the chromosomes attach and mitotic division takes place. These are present only in animals and they are absent in plant and fungal cells.

2. Vacuoles are the storage organelles which store excess water, waste metabolites, sugars and other components in them. In plant cells they are of larger size whereas the vacuoles are small in size in case of the animal and fungal cells.

3. The plants cells and fungal cells have cell wall made up of cellulose (plants) and chitin (fungus) respectively. The cell wall is absent in animal cells.

4. The plant cells and fungal cells do not possess cilia and flagella for locomotion whereas animal cells have cilia and flagella.

Part 1: Explore

Based on your research and observations of the three common states of matter, answer the

following questions.

Out of the videos, animations, and images you researched, which was your favorite? Why?

Do you feel it accurately represented the differences between each state of matter


How does the space between the particles in each state of matter differ?

How do the particles in each state of matter move?

Part 2: Explain

Examine the heating curve of water below, and then answer the questions about it. If you require the use of a text reader, open the file Heating Curve of Water to receive the information.


Which three parts of the graph’s curve represent the solid, liquid, and gaseous state of water?

Explain your reasoning.

Which point of the graph’s curve represents the melting point of water? Explain your reasoning.

Which point of the graph’s curve represents the boiling point of water? Explain your reasoning.

What happens to the energy of water in Part B and Part D of the graph’s curve? How do you know?

Why does the temperature of the water stay the same when it melts and boils?

Now comes the hands-on part of your project! You will continue to explore phase changes by performing an experiment and creating your own heating curve. Before you begin your experiment, read over the following information.


The materials you will need for your experiment are listed below.


small pot

measuring cup (must have mL and oz markings)

spoon (wooden, plastic, or metal)

ice

water

stove

thermometer (should have units in °C

Place 14 oz of crushed ice into a small pot. Then add about 125 mL of water to it.

Using the thermometer, measure and record the initial temperature of the ice water. List this temperature in °C in the “0” minutes row of your data table in the lab handout. *Do not allow the thermometer to touch the bottom of the pot when recording measurements.

Place the pot on the stove, and turn the knob to the medium-low setting.

Using the thermometer, measure the temperature every minute until the water begins to boil vigorously. Record this data in the table on your lab handout.

At each measurement, also record what is happening to the water. Be sure to record the times of these events:

The ice melts.

The water forms steam.

The water begins to boil.

Once the water has begun to boil, stir the water constantly with the spoon.

Continue to measure and record the temperature every minute until almost all the water has boiled and the pot is close to empty.

Record the last temperature, and turn off the stove. DO NOT TOUCH THE POT WITHOUT SAFETY EQUIPMENT.

Create the x-axis and y-axis of a graph.

Label the x-axis as follows: Time (min).

Label the y-axis as follows: Temperature of Water (°C).

Along the x-axis, create and label 15 marks, one for each minute of the experiment. (Hint: The origin starts at 0.)

Along the y-axis, create and label temperature markings for every 20 degrees. (Hint: The origin starts at 0.)

Refer to the data from your experiment to plot the points on your graph. Then connect each of the data points with a line.

Look over your graph to make sure it is clear and correctly labeled.

Either save your graph as a computer file, or take a picture of your graph and upload it as a file on your computer.

Describe your experience in performing the experiment. What went well? What could have been

improved?

Examine your line graph. How does the graph’s slope change over time?

Examine your line graph. Why does the slope change?

How could you apply the knowledge gained from this experiment in the real world?

Hint: Think of cooking.

Make a prediction. How do you think adding other substances to the water would affect its

heating curve?

The Colorado River provides water and electricity for over 40 million people. But so much water is withdrawn from this river for agriculture/livestock and drinking water, that very little of it reaches the sea. Due to drought and overuse, it currently is drying up. This will be a major problem because crops and livestock in the USA depend on this water. What percent of the nation's crops and livestock rely on the river's water?​
