Unit A: Cells
Part A: Scientific Method
Test with an experiment
You need to prepare the materials, and make a basic method plan
Materials
Bubble Gum ( 1 person each )
A scales ( count on gram )
A Lab to record
Wrappers
A Human
Sanitizer, A paper towel to clean the scale
Method
Weight the bubble gum,
Record the data (initial weight) on the lab,
Chew it for 5 minutes,
Waite until it is dried,
Put it on the scale , record the data,
Do a data compare,
Do a conclusion.
Procedure working (Yes/No)
No, not in my expactation
Construct a hypothesis
From my own point of view, I think the weight of the bubble gum will increase.
Analyze the data
Average difference: 4gram
Do background research
No background research for this question
Make a conclusion
Ask a question
What will happen after we chew the bubble gum?
Start with observation !

Part B: Plant & Animal Cell
Plant Cell
Animal Cell
Plant & Animal Cell Organelle Functions
Nucleus:The nucleus controls and regulates the activities of the cell
Vacuole: In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance. Sometimes a single vacuole can take up most of the interior space of the plant cell.
Cell wall: It provides the cell with both structural support and protection, and also acts as a filtering mechanism.
Cell membrane:
The cell membrane regulates the transport of materials entering and exiting the cell.
Endoplasmic Reticulum:its function is to produce proteins for the rest of the cell to function.
Golgi Apparatus:The Golgi apparatus transports and modifies proteins in eukaryotic cells
Chloroplast: Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant.
Lysosomes: The lysosomes digest the energies
Cytoplasm: The cytoplasm functions to support and suspend organelles and cellular molecules.
Nuclear Membrane:It serves to separate the chromosomes from the rest of the cell.
Mitochondria:
The mitochondria generate most of the chemical energy needed to power the cell's biochemical reactions.
