Today in class students will complete pages 261-262 in their Science Fusion books. In this activity the books wants the student to go outside and stake out a 1 by 1 meter square and observe the different features in the square. With the weather as poor as it is instead they will watch a video of a person creating a closed native terrarium. I will post the link below.
Page 261
For Set a Purpose:
Answer the question "What do you think you will learn in this activity" think about why it is important to see what native plants and animals live near you. You do not need to answer "why did you measure and mark your sample area".
In Think about your procedure:
After watching the video think about why it is important to have a variety of different biotic and abiotic features within the terrarium. Change the question to "Why do you think your sample site should have a variety of biotic and abiotic features.
In Record your data:
Use the space below to make a t-chart or two columns. One side should be labeled biotic and the other abiotic. While watching the video write down all biotic and abiotic features put inside the terrarium.
Page 262
Draw Conclusions
In the first question it asks you how did you determine the roles that each living thing played. Pick two organisms that your wrote in the record your data section. Write what roles those two organisms play in the terrarium.
The second question asks to compare with another group. Cross out this question because you cannot complete it.
Analyze and Extend
I will bold the changes to the questions.
1) This question does not change
2) Which role in the ecosystem had the greatest amount of living things between plants and animals?
3) Which role in the ecosystem had the greatest variety Abiotic or Biotic?
4) Draw a picture of the terrarium.
5) You must write two questions.

Science Fusion Vol 1 Pages 39 & 40 "How Do You Perform a Controlled Experiment"
Today in class students will be completing pages 39 & 40 in their Science fusion books. The students will perform an experiment to see how different floor material affects the height at which a ball bounces. This will be the students first controlled experiment.
On Page 39...
You will need to set a purpose. The purpose is what you are trying to learn from the experiment. When writing your purpose begin with the statement "I will learn how..."
For think about the procedure you need to identify the variable in the experiment. Remember that the variable is the condition in an experiment that can be changed. In this experiment their is one variable that you will be using. Think about what you are changing during the experiment and what will stay the same. The one thing that you are changing during the experiment will be your tested variable.
On the record your data section you will test four different surface materials for your experiment. The surface materials can be things such as hardwood floor, carpet, a notebook etc. For the experiment the ball and the height that you dropped the ball from need to be the same throughout the entirety of the experiment. Do not forget to do five trials on each material. So if your first surface material is carpet you should drop your ball on carpet five times and record your data each time. Remember that the only thing that you change throughout the experiment is the surface material. Do not change the ball of the height at which you drop the ball. After you have done your five trails for each surface material you will need to find the average. To find the average you will add all of your trails for one surface material together than divide by the amount of numbers you added together. To find the average for the five trials you will divide by five
An example,
Surface Material Trail 1 Trail 2 Trail 3 Trail 4 Trail 5 Average
Wooden Desk 10cm 15cm 8cm 12cm 10cm 11cm
To find the average I added 10 + 15 + 8 + 12 + 10 = 55
Then I divided 55 by 5 to get 11
This means that my average is 11
For recording data for each trail I would like you to use centimeters if possible. All students may not have a meter stick at home. If you are recording your data at home use whatever mearing tool you have available.
For page 40 you will complete all of the questions. If you have any questions regarding a particular question please feel free to email me.
If you are not in school try to turn your assignment in within the week that you come back.
