Engage your mind

● What process is going on?

● What are the conditions and

materials needed for this

process?

● What are the products of this

process?

● Compare the gas bubbles in both

jars.

● What causes the difference in gas bubbles?

● What is the gas in these bubbles?

Explore

● Make a hypothesis about the nature of the

gas found in the bubbles produced.

● Make a prediction

● Design your own experiment

Explore

1. Compare Jars (a) and (c).

2. Describe what happens to

the mouse in jars (b) and (d).

3. Deduce the role of the

plant in jar (c).

4. Does this experiment validate

your hypothesis? Explain

5. How can you relate this experiment to our real world?

Explain

Explain

How does the plant take water?The plant absorbs the water through its roots by osmosis by transport tissues

called xylem.

How does the plant take Carbon Dioxide?Leaves contain special structures called stomata that are able to open and

close and absorb Carbon dioxide to cells.

How does it produce oxygen and sugar?Inside the cell, the chloroplast, that contains chlorophyll pigment,uses the

water and carbon dioxide to make a chemical reactions to produce Oxygen

and Glucose sugar.

How could we purify our earth

from this pollution? How can we

start from our class??

Evaluate

You are leaves applying for a job in photosynthesis company. Create

your“resume”, explaining your job qualifications and describing how you will

efficiently get the job done. Descriptions must include key vocabulary such as

stomata, water, carbon dioxide, light, energy,chlorophyll and chloroplast.

But where does the sugar go??

a. The sugar is stored in plant cells.

b. The sugar is extracted from cells to be used

by us.

c. The sugar is used by plant cells to produce

energy.

Lab DemonstrationMaterials: Yeast- sugar- water - 2 beakers - spoon - balloon

Procedure:

● Add two spoons of yeast in each beaker.

● Add same amount of water in each.

● Add in one of them one spoon of sugar.

● Observe

● Collect some of the gas produced by a balloon and then empty it in a

small test tube containing lime water.Observe.

Conclude: What is the gas produced by yeast? Justify your answer.

Explore

1. How does the presence

of sugar affect the

production of the gas?

2. Yeast are living cells.

What is the name of the process

done in these cells?

Explain: Cell Respiration

Explain

How is the energy of the sun converted to

energy for cell?

The sugar produced by photosynthesis will

react with oxygen inside the mitochondria of

cells to produce carbon dioxide, water, and

energy in the form of molecules called

adenosine triphosphate (ATP).

In hospitals, it is not allowed to keep plants

inside the patient’s room, why do you think

doctors forbid it?

photosynthesis and cell respiration together in

plant cell and animal cell.
