Unit 6
Activity 1.
Choose Your Own Plant Experiment
During this entire Unit, you will perform an experiment with plants. You will choose what the experiment will be. It can be on how different substances (such as coffee) affect seed germination. It can be something to the effect of: does yelling at one plant and singing to another plant affect growth? Keep in mind the variables. If you choose seed germination, make sure that you choose the same seed. If you choose yelling or singing at a plant, make sure it is the same type of plant growing in the same environmental conditions.
Your experiment is of your choosing. In each activity, there will be certain items due.
You need to decide what your experiment will be, form a problem sentence and hypothesis, and do background research. You will need to start your experiment as soon as possible so the plants have a chance to germinate/grow. You can look on the internet for ideas if you cannot think of one on your own.
Here is the rubric for activity one - for maximum points be sure to include as many of the elements in the green box on the far right as possible:)
Activity 2.
Plant Experiment, Continued
For this part of the activity, you will record your data from your experiment using a data table. An example data table is below for reference. Although you may need some more time, make sure this part is complete before you start Activity 3. You may want to make a working copy and put your final copy here. If you need help setting up the data table, ask a teacher for assistance. You can make it bigger, if needed.
Your data can be:
Quantitative Data - measurements and numbers
Qualitative Data - characteristics and direct observations
or a combination of both
Below is the goal on the rubric for maximum points.
Activity 3.
Plant Experiment Conclusion - Essay.
Answer the following questions.
1. Answer your hypothesis.
2. Quote your data. (Use some of the numbers from your data table which make the strongest point for your conclusion.)
3. Error: Describe any sources of error in the data collection.
4. Tell how these errors affected the results—did the errors make the measurements larger or smaller?
5. Explain changes you could make to the experiment to make these errors smaller. Explain other experiments this experiment made you think of.

Activity 1.
Roundworms
One square meter of garden soil can contain millions of roundworms.
In this activity, you will examine soil for roundworms.
If you do not have access to the materials, you may answer based on this video:
Steps
1) Place a small amount of garden soil into a petri dish.(No one has a petri dish at home, use a paper plate or something mom and dad wont mind you getting dirty! You can put your sample on a piece of paper!)
2) Use a hand magnifying lens to examine the soil. (Don't have a magnifying glass? Try using your phones camera, then you can zoom in close and take pictures of what you see!)
3) The roundworms will be small, white, threadlike animals.
It is time to record your findings.
1. Describe the movement of the roundworms in detail.
2. How many roundworms are in your sample (that you can see)?
3. How are roundworms suited to their habitat?
Type and submit your answers to the word processor below. Be sure to answer each section thoroughly and use complete sentences. Your teacher will grade this assignment.
Activity 2.
Comparing the Hair of Mammals
Mammals all have hair, but that hair can be very different from one mammal to another or even on the same mammal.
Your goal is to observe and compare at least 3 different samples of hair.
If you do not have access to the materials, you can search for videos of each type of hair under a microscope. Cite the link to the video in your response.
Steps
1) Collect Observe different types of mammal hair that you can find (human, dog, cat, goat, etc.) Do not go cutting off people or pets hair please, just observe and document:)
2) Prepare slides of all the different types of hair. No one has microscopes at home, observe and draw what you see! You can use your phones camera to zoom closer like a microscope for a closer view!
3) Examine slides under a microscope.
4) Draw diagrams and write brief descriptions of each type of hair.
Once you have finished, upload to your teacher for grading.

Distractions (Reaction Time)
How Does Distraction Affect Reaction Times?
Get a partner and sit facing them as they stand.
Extend one of your arms toward your partner with your thumb and fingers parted about an inch. Have the partner hold the top of a meterstick or yardstick just above your outstretched hand, with the "0" mark just above your fingers.
Have your partner drop the stick straight down between your fingers.
Catch the stick between your thumb and fingers as soon you sense it begin to fall. Note how far "up" the stick it fell before you caught it. Record 10 trials of this process in your essay box under the title "Undistracted."
Now count backwards from 100 by fives (100, 95, 90, 85, etc) to distract your senses. Repeat/record the test 10 more times and record under the title "Distracted."
Compare the results, and answer the following questions in your essay box:
Did your reaction time improve with each trial?
How was your reaction time measurement affected by distraction? (Quote your data.)
What other factors, besides distraction, might also decrease reaction times?
