notebook

Question

Which is more effective at absorbing nutrients – one large cell or many small cells?

Research

Think about what you already know or have already seen, experienced or heard of that might give you a clue so you can make an educated guess at the answer to this question. Write down at least 3 in your notebook. Here are some ideas to help you out:

Think of examples of times you’d rather have many small items as opposed to one large item.

Think about things that are meant to absorb. BONUS: Think about labs from our energy unit. Is

there one you can think of that might give you a clue to answer this question?

Hypothesis

Write your hypothesis in your notebook. Be sure you:Tell what you think is the answer

to the question.Give reasoning for why you think

your answer is correct.Include items from your

research in you reasoning.

Procedure

Read the procedure for this model from the online textbook. Document the procedure in your notebook in one of the following ways: Diagram with labels showing what goes in

each spot on the sepup tray. Comic strip or illustrations for each step of

the procedure. A paragraph telling what steps you will take.

DO NOT COPY THE EXACT PROCEDURE FROM THE BOOK.

Data

Create a data table in your notebook to document your observations. View the photographs on the following slides and fill in your data table accordingly.

large cells and which

represents small

cells?

Results

Carbon pieces on the left and carbon powder on the right.What represents the “nutrients” in this model? How can you tell if the “nutrients” are being absorbed?

Results

Are large cells or small cells better at absorbing nutrients? How can you tell from this model?

Conclusion

Are large cells or small cells better at absorbing nutrients? What is your evidence? Make sure to explain how your evidence proves your answer. Write this conclusion in your notebook.
