9TH GRADE SUMMER CAPT ASSIGNMENT (For 8th grade students entering Honors Biology) Name: _____________________________________ Why do you have a summer assignment? Students entering Honors Biology will be missing the 9th grade course information. The 9th grade Earth Science course information will appear on the CAPT or the newer SBAC Test. The summer assignment ensures that you are exposed to the information so that you can be successful on the state assessment. What resources will you have in order to complete the summer assignment? You will need to create an account on Schoology.com. The ACCESS CODE for the 9th Grade Honors Biology Summer is 2H8X8-TP3BC You will have access to the PowerPoints on Schoology, state laboratory materials, and a textbook. You can also access the internet for further research if needed. How will you be held accountable for the summer assignment? The due date for the summer assignment is Monday, August 25th. If your packet is not at school by this date, I will contact your counselor to place you in Honors Earth Science. There are several options for turning in your packet o Bring it to school and turn it in directly o Scan the pages and email to jblasi@region16ct.org o Fax it to the school (203)881-2015 o Mail it to the school Jill Blasi Woodland Regional High School 135 Back Rimmon Road Beacon Falls, CT 06403 There will also be a mandatory assessment given within the first few classes that you will need to pass in order to remain enrolled in Honors Biology. It is suggested that you keep a copy of the summer assignment to use to study for the assessment (along with the on-line PowerPoints). You will need to return the textbook before the start of the school year as we need the books for the incoming Earth Science students. What happens if you do not successfully complete the summer assignment and/or if you don’t pass the mandatory assessment? You will be required to drop Honors Biology and enroll in Honors Earth Science. What happens if I have a question on the summer assignment or need help? You can email Mrs. Blasi, the science department chairman at jblasi@region16ct.org.

Please answer the following questions on a separate piece of paper. Make sure your responses are numbered and in complete sentences. Polymer Investigation A group of students wrote the following procedure for their investigation. Procedure: 1. Tightly wrap a sample of kitchen wrap from manufacturer A over the top of a coffee can. 2. Place a 10-gram weight on the kitchen wrap to see if it breaks. 3. Continue to add 10-gram weights one at a time until the kitchen wrap breaks and the weights fall into the can. 4. Record the number of 10-gram weights the kitchen wrap held before breaking. 5. Repeat the procedure exactly for a sample of kitchen wrap from manufacturer B. 6. Repeat the procedure exactly for a sample of kitchen wrap from manufacturer C. Question #1: What question were the students attempting to answer with this investigation? Question #2: Identify the independent variable and the dependent variable in the group’s investigation. Polymer Investigation A manufacturer claims that its kitchen wrap will stretch twice as much as the leading competitor’s plastic wrap without tearing. A group of students has gathered the following materials to test this claim. • • • • • • one sample of kitchen wrap from the manufacturer making the claim one sample of kitchen wrap from the leading competitor masking tape one clamp with a hook for adding weights several weights a metric ruler The students wrote the following procedure for their investigation. Procedure: 1. Take the sample of kitchen wrap from the manufacturer making the claim and attach one edge of the wrap to a table or desk with the masking tape (leaving the free end hanging down). 2. Attach the clamp to the free-hanging end of the kitchen wrap. 3. Add weights to the clamp. 4. Measure how much the plastic stretches. 5. Repeat steps 1–4 for the leading competitor’s kitchen wrap. Question #3: Describe at least three steps or pieces of information the students should add to the procedure to improve the design of their experiment. Polymer Investigation A student performed the following investigation to test four different polymer plastics for stretchability. Procedure: 1. Take a sample of one type of plastic, and measure its length. 2. Tape the top edge of the plastic sample to a table so that it is hanging freely down the side of the table. 3. Attach a clamp to the bottom edge of the plastic sample. 4. Add weights to the clamp and allow them to hang for five minutes. 5. Remove the weights and clamp, and measure the length of the plastic types. 6. Repeat the procedure exactly for the remaining three plastic samples. 7. Perform a second trial (T2) exactly like the first trial (T1). The student recorded the following data from the investigation. Data Table Plastic Type A B C D Amount Stretched (mm) T1 T2 10 12 22 23 14 13 20 20 Question #4: Draw a conclusion based on the student’s data. Question #5: Describe two ways the student could have improved the experimental design and/or validity of the results. Solar Cooker Investigation A group of students has designed a solar cooker for an investigation. They are investigating whether the material that a container is made of has an effect on the rate of temperature change over time. They obtain three containers of identical size. They add water to each container. The containers are placed inside the solar cooker, which is made of a box lined with aluminum foil. Question #6: Identify two additional pieces of equipment that the students will need to use in their investigation. Question #7: Explain why each piece of equipment is necessary. Solar Cooker Investigation A student hypothesized that container size will affect the performance of solar cookers in heating water. The student wrote and performed the following procedure to support her claim. Procedure: 1. 2. 3. 4. 5. 6. 7. 8. 9. Line three identical cardboard boxes with aluminum foil to use as solar cookers. Place the solar cookers outside in direct sunlight. Place a large glass container of water in the center of the first box. Record the initial temperature of the water. Allow the container to sit in the sun for 2 hours, and then check and record the final temperature of the water. Place a medium-sized glass container of water in the center of the second box. Repeat steps 4 and 5. Place a small-sized glass container of water in the center of the last box. Repeat steps 4 and 5. The chart below shows the student’s data. Solar Cooker Data Container Large Medium Small Temperature (°C) Initial Final 39 48 39 49 39 49 Question #8: Draw a conclusion regarding container size and the effectiveness of solar cookers in heating water, based on the student’s results. Question #9: Describe two ways the student could have improved her experimental design and/or the validity of her results. Acid Rain A group of students wrote the following procedure for their investigation. Procedure: 1. Determine the mass of four different samples. 2. Pour vinegar in each of four separate, but identical, containers. 3. Place a sample of one material into one container and label. Repeat with remaining samples, placing a single sample into a single container. 4. After 24 hours, remove the samples from the containers and rinse each sample with distilled water. 5. Allow the samples to sit and dry for 30 minutes. 6. Determine the mass of each sample. The students’ data are recorded in the table below. Sample Marble Limestone Wood Plastic Starting Mass (g) 9.8 10.4 11.2 7.2 Ending Mass (g) 9.4 9.1 11.2 7.1 Difference in Mass (g) –0.4 –1.3 0.0 –0.1 Question #10: After reading the group’s procedure, describe what additional information you would need in order to replicate the experiment. Make sure to include at least three pieces of information. Acid Rain Investigation A group of students wrote the following procedure for their acid rain investigation. Procedure: 1. 2. 3. 4. Find the mass of each of three different building materials being tested. Pour 200 mL of acidified water, pH 4.5, into each of three clean containers. Place each sample of building material into one of the three containers. After two days, remove the samples, wash them with distilled water, and allow them to dry completely. 5. Mass each sample. The chart below shows the students’ investigation results. Material Granite Marble Limestone Starting Mass (g) 6.2 8.7 5.3 Ending Mass (g) 6.2 8.1 4.1 Difference in Mass (g) 0.0 0.6 1.2 Percent Loss 0.0 6.9 22.6 Question #11: What was the problem the students were investigating?
