Here are photos of the notes we've taken in the past month as we've learned about ecosystems and plants who are the producers because they can make their own food.
The quiz will mostly be matching, and fill in the blank with a word bank available:
The perennials have the advantage of having all the food they stored last year so they can grow early and very quickly in the spring when they wake up.
Your job this week is to find two interesting perennials in your natural area and draw what their growth looks like so far this spring.
One should be Woody Stemmed, and one should be herbaceous stemmed with new growth coming from the ground since only the roots survive the winter.
Be sure to take note of which plants you draw so you can come back in a month and revisit the same plant to see how it has progressed. Try to really capture details! Look close! Use words to describe them because they will be changing a LOT in the next few weeks.
Here are my examples: The first is in progress, showing how you should use a regular pencil to capture the shape and proportion and to label you drawings.
The second is closer to being finished with some added color and more labels describing what I was seeing.
Over the next few weeks we will be studying Ecosystems in class and thinking about how organisms can still be wild and live and grow even in the City of Chicago where humans have changed the environment drastically.
In order for you to do your own study, your homework this week is to identify an interesting natural area near your house that you can get to without any trouble at all. As you think about what spot to choose, keep these things in mind.
- Easy Access - Be sure that you can get to this location easily and quickly so that you can visit it when your family's schedule and the weather give you a window. Don't choose an area that is going to be a hassle for you or your family. Good options are your yard, your neighborhood park, or areas along your street where animals and plants are growing and living wild.
- Make sure you can identify a number of different plant and animal populations that live in your natural area even if it's very small. (We will try to identify the organisms you are observing, but it's ok if you are not sure the actual species names. "Tall grasses, red ants, a rabbit, Pine tree, moss" - these can be specific enough for this project.
- Make sure that your natural area has at least one woody stemmed perennial like a bush or a tree. Something that has bark.
- Spend some time in a few different areas before choosing so that you know you have found an interesting natural area to spend time observing.
Once you have chosen your location, complete the description page we set up in our journals.
If your natural are is very large like a park, be sure to describe what part of it you will be focusing your work in.
Here is a picture of the blank journal set up if you forgot to take yours home.
In case you forgot your graph at school or didn't have time to get strated, here is how we set up the axes so you can create your graph before your next class.
Choose how to label the y-axis so that your highest mean voltage will be graphed near the top of the graph paper. (Many students are numbering by .1 volts.)
You might need to add your extra angle if you tested one. Be sure that it is in the correct location on the x-axis.
Graph your means for each angle on the graph by placing TWO dots on the line above each angle you tested. Choose two different colors for the dots showing the data from your Control and Experimental Blades and make a key so we know which is which.
You and your partner collected the data so YOU two are the source for the data.
Remember, we are going to talk about how to connect the dots using a "best fit line" in class so
DO NOT CONNECT THE DOTS OF YOUR GRAPH!
Experimental Design Vocabulary List
Experimental Question – A testable question that asks how a change you make might affect the results or what happens.
“If we change this.... does it affect that?”
Hypothesis – What you expect to happen to the results based on the change you will make and
other evidence you have gathered.
Variables – Anything that could change during an experiment that might affect the data and results.
Dependent Variable – What scientists measure to see if it has changed during the trials. This becomes your data f
or the experiment.
Independent Variable – The variable that is being tested. Scientists carefully change it on purpose to see the effect
it will have on the data and results.
Controlled Variables – All the other variables that are kept the same to be sure that they do not have any effect.
This makes the experiment a fair test.
Procedure – Step by step directions for how to run a set of trials. Each trial gathers one piece of data
and observations
Control Group – A set of trials where the Independent Variable is NOT being changed and tested.
Experimental Group – A set of trials where the Independent Variable IS being tested. The I.V. is changed on purpose
and the results are then compared to the control group.
Data Table – A chart for recording and organizing the data and calculations.
Graph – The data presented in visual form using bars or lines.
Data Analysis – Objective, mathematical thinking about the data.
Observations – Objective Statements about what scientists noticed during the trials. Can be used as evidence.
Conclusions – Subjective thinking and analysis of the results. What scientists think about the results of the
experiment.
Repeatability – The ability for other scientists to follow a procedure and get similar results.
Your experiment testing variables that affect voltage from our Solar Panels is over!
Now it is time to use your writing skills to explain to other scientists what you think about the experiment we just did.
You are trying to communicate your ideas to other scientists so clear and complete sentences are absolutely necessary.
You can hand write your paragraph but most of us are using our drive account and a google doc in your science folder on drive. Don't print it out! We will be having a peer review session to help improve our writing and to help us make sure that we are thinking clearly about the results of our experiments. Then we will print them in class.
CONCLUSIONS INSTRUCTIONS:
Write a paragraph for each of the three sets of questions to discuss what you think about the experiment we just completed - You don't have to answer every question, but think about each one as you choose what to write.
Wherever you can, USE EVIDENCE to support your ideas. "I think this because....facts." Evidence can be from the data, from your own observations, or what we learned from our research in the sciencesaurus books about light which has a lot to do with the voltage our panels produced.
For this to make sense to someone who reads it your sentences should restate some of the questions in your paragraph.
Example:
Instructions Question: Do the results support your hypothesis?
your paragraph: My hypothesis was not supported by the results of the test.
Paragraph One Theme: What do you think about the materials now? Has your thinking changed or been reinforced?
Tell us about your hypothesis first. then think about these questions:
Did the results of this experiment support your hypothesis or do you think something different now?
Which materials didn't behave like you thought they would?
Which results surprised you?
Which materials surprised you? What do you think about how light interacted with that material now?
What new things did you observe during the test that might help explain what happened to cause the different voltages we measured?
Paragraph Two Theme: Do you think that we can trust the results of the experiment?
First look at your own teams data all by itself.
Does the data show a clear difference between the experimental groups and the control group? Did some tests clearly produce more voltage than others? How much more? Are some groups very close together (How close?) with data that overlap This can make it hard to know which one actually produced the most and may mean we would need to run more tests to learn more.
Are there pieces of data or groups of trials that look strange and don't follow the pattern/ These might be outliers and make you trust the result a little less. Are your ranges small enough to trust?
Did other teams in other classes do similar experiments that could support your results?
Think about your procedure and your testing setup:
How well did your team do at controlling variables that might have affected the data?
What are some variables that you know were not completely controlled between your groups of trials?
Are there problems with our materials or procedures that make you trust our data less? Describe them in detail.
Paragraph Three Theme:
How could we improve or expand on this experiment if we were going to do it a second time?
What could we change about our procedure and how we ran our trials to improve the fairness of your test and make the results more consistent and trustworthy or more clear between the materials that seem similar.
Should we have run more trials?
What other materials could we use to design a better testing setup or a new experiment to learn more about how the things that affect our solar panels?
Now that your team has finished collecting data it's time to start thinking about the results and how you think we did conducting a Fair test that tested just a single variable.
Your first work should be to finish the graph that your team set up in class if you did not get done before the period ended. (Don't rush! A graph is only useful if it allows us to see the data clearly. )
Before we start writing our conclusions, you should do some thinking about the experiment your team designed.
Complete the questions on the Variables Homework Sheet.
Here are the questions if you lost your copy.
Name: _________________________ Homeroom Teacher: _______________Team Number: ____
Instructions: Please answer the questions below to prepare for next week's team discussion on writing conclusions.
Question: Which specific variable did your team choose to test? (This is the one thing you changed on purpose).
Write your answer here:
Question: Which variables did your team successfully keep constant (the same) throughout the experiment so they would not affect your data?
Please list the variables and explain specifically how you ensured they stayed the same.
Variable 1: _______________________________________________________
How we controlled it: ___________________________________________
Variable 2: _______________________________________________________
How we controlled it: ___________________________________________
Question: Which variables did your team struggle to control? (These are factors that may have unintentionally changed and affected the voltage output of your solar panels).
Question: Look at the variables you listed in Question 3. For each one, describe how you could redesign the experiment to control it better next time.
Idea 1: _____________________________________________________________
Idea 2: _____________________________________________________________
Look at the list of variables that we think might affect the voltage our little solar panels can produce.
Choose one that you think would be interesting to test. This variable becomes your Independent Variable, the one we change on purpose to see how much it changes our data.
Draw a clear diagram (labels!) that would show how you would set up the equipment to run a fair test. This diagram can serve as a materials list too, so we know what things we need to get from the store room or from home.
Also think about which variables we'd have to work to control so that they don' t change the voltage while we are testing your Independent Variable. What do we have to do the same way every time so the test is fair?
In the next few weeks we will be trsting some variables that affect how much voltage our Mini Solar Panels and Mini Wind Turbines can produce. You job is to come into the discussion next week with a list of variables that we could test (or control) to learn more about what things affect the electrical output of our Panels and Turbines.
Here are the notes we set up in our journal in case you forgot yours at home:
The experiment is over! Now it is time to use your writing skills to explain to other scientists what you think about the experiment we just did.
Clear and complete sentences are absolutely necessary. Be sure to have a good draft of all three paragraphs ready to show to other students at your first class next week.
You can hand write your paragraph but most of us are using our drive account and the google doc you set up. Be sure to have something to share with your team. Don't print it out before class. We will be having a peer review session to help improve our writing and to help us make sure that we are thinking clearly about the results of our experiments. Then we will print them in class.

Paragraph Two Theme: Do you think that we can trust the results of the experiment?
Look at your data, the class data, your graph and the GRADE wide means.
Does the data show a clear difference between the experimental groups? (Did some materials clearly warm up the thermometer more than others, no matter who was running the test?)
Look at the graph showing the maximums and minimums for each experimental group.
Does some of the data overlap and show that sometimes one material heated up more than others, but not always? (This can make it hard to know which one actually heated up the most.)
Are there pieces of data that look strange and don't follow the pattern/ These might be outliers and make you trust the result a little less.
Did other classes in the grade get similar results and show repeatability?
Are the results "too close to call" or can we be sure that we know one material heats up more?
Think about our procedure:
Are there problems with our materials or procedures that make you trust our data less?
Paragraph Three Theme: How could we improve or expand on this experiment if we were going to do it a second time?
What could we change about our procedure and how we ran our trials to improve the fairness of our test and make the results more consistent and trustworthy or more clear between the materials that seem similar.
Was there a problem with our location or our materials?
Should we have run more trials?
What other materials could we use to design an experiment to learn more about the absorption of light?
If you designed another test to study the absorption of light and how it heats up materials, what could it look like?
