Student Designed Experiment
have set up a habitat for your spider and made some initial observations.
The observations lead to questions about your spider. You will design
an experiment to answer your questions. In the process you will learn
more about your spider. This is what a scientist does.
Guidelines for developing your experiment
- Work with your lab partner. On a separate
piece of paper write down your name and your partner's name.
- Think of a new question or choose one
from the list of class questions. Select a question or a topic you
would like to learn more about. You will be designing an experiment
to answer your question. Discuss with your partner how you might go
about answering the question. Write down the question.
- Write a hypothesis based on your question
and previous observations.
- Develop and write a procedure to test
your hypothesis. You will be given four 30-minute sessions to work
on your experiment in class. Describe what you plan to do each of
those times. Will you need extra time outside of class (lunch time
or after school)?
- List the materials you will need and
where you will get them.
- What data will you collect?
- Turn in your plan to the teacher. Make
sure you have completed items #1-6.
Follow your procedure and collect data. Record
your raw data (as you collect it) on a separate piece of paper.
How will you present your data? You need to select
at least two different ways to present it. Select the ways that will
best present your data from the following list:
Each one should be large enough to fill a separate 8.5"
x 11" piece of paper.
Results and Conclusions
Write 2-3 paragraphs, each containing 5-7 sentences
discussing your experiment. Discuss what the data are telling you. Describe
any patterns your data suggest. Explain what you did and why. Talk about
what went well and what did not go well. Suggest changes to the procedure
that you would do (or recommend) next time. What conclusions can you
learn about the information you gathered? What did you learn?
Presentation to the Class
You and your partner will present your experiment
and findings to the class for peer review and evaluation. Together with
your partner make a poster illustrating your experiment and the data
you have collected. Use the poster in your presentation.
What you need to turn in:
- Data Record Sheet (raw data)
- Two Representations of your data
- Written Results and Conclusions
- Your Poster
Write an abstract.
An abstract is a one paragraph summary of the
experiment and what was learned. You and your partner will match up
with another team. Your task is to write an abstract for their experiment,
and they will write one for yours.
