WHS Honors Biology Summer Assignment Welcome to Honors Biology!!! We congratulate you on choosing a rigorous curriculum for your ninth grade year at Woodstown High School. We have high expectations and hope that you are ready to learn! The Assignment: The summer assignment packet is designed to review with you graphing scientific data, writing hypotheses, identifiying variables in experiments and reviewing prefixes and suffixes to help with learning scientific vocabulary that will be used all year. The entire packet should be completed. Due Date: This assignment is due the first day of school. If your assignment is late, you will receive a 10 point grade deduction and an Academic Detention the first day of school. You will take an assessment covering this material the first week of school. Materials Needed For Honors Biology: This course requires a 1 – 2 inch 3 ring binder, notebook paper, pencils and pens, and 2 marble notebooks (1 for labs and 1 for Science Fair). One of the requirements of Honors Biology is a Science Fair Project. Over the summer you might think of some ideas of what you would like to do. We will begin the Science Fair process in early October. If you have any questions during the summer about the assignment, you may contact Mrs. Adams at adams.a@woodstown.org or Mrs. Sorbello at sorbello.j@woodstown.org. 1 Biology Prefixes and Suffixes Learning science vocabulary can feel like learning a different language, mainly because it is! The roots of most of these words are either Latin or Greek. By breaking them down and learning the meaning of their prefixes and suffixes we can begin to "speak scientist!” Look up the meaning of each prefix and suffix below. Prefix Ab Anti Auto Bi Cyto Di Macro Meta Micro Mono Hemi Hetero Homo Hydro Hyper Hypo Inter Intra Iso Neuro Path Poly Photo Pseudo Sub Therm Trans Tri Un Zoo Meaning Suffix -asis -blast -emia -genic -gram -graph -ism -ist -itis -kinesis -lysis -meter -oma -osis -otomy -ous -phyll -philic -phobic -scope Meaning 2 Hypothesis & Variable Statements Define the following: HypothesisIndependent VariableDependent VariableA hypothesis is usually written a particular way. Hypothesis are written as an “If this, then that” statement. In the following statements, create a hypothesis and identify the independent variable and then the dependent variable. 1. Will loud music affect the height of corn plants? Hypothesis: ___________________________________________________________________________________________________ _________________________________________________________________________________________________________________ Independent Variable: _______________________________________________________________________________________ Dependent Variable: _________________________________________________________________________________________ 2. Will nicotine affect mold growth? Hypothesis: ___________________________________________________________________________________________________ _________________________________________________________________________________________________________________ Independent Variable: _______________________________________________________________________________________ Dependent Variable: _________________________________________________________________________________________ 3. Will growing tomato plants in water affect mass size? Hypothesis: ___________________________________________________________________________________________________ _________________________________________________________________________________________________________________ Independent Variable: _______________________________________________________________________________________ Dependent Variable: _________________________________________________________________________________________ 4. Will salt in water affect the breathing rate of a goldfish? Hypothesis: ___________________________________________________________________________________________________ _________________________________________________________________________________________________________________ Independent Variable: _______________________________________________________________________________________ Dependent Variable: _________________________________________________________________________________________ 5. Will the use of bug spray attract fewer mosquitoes? Hypothesis: ___________________________________________________________________________________________________ _________________________________________________________________________________________________________________ Independent Variable: _______________________________________________________________________________________ Dependent Variable: _________________________________________________________________________________________ 6. Will eating cake every day increase a person’s health? Hypothesis: ___________________________________________________________________________________________________ _________________________________________________________________________________________________________________ Independent Variable: _______________________________________________________________________________________ Dependent Variable: _________________________________________________________________________________________ 3 GRAPHING RULES AND TIPS 1. Bar and line graphs contain a horizontal “X” axis and a vertical “Y” axis. 2. The independent variable is plotted on the “X” axis and the dependent variable is plotted on the “Y” axis. Y dependent variable X independent variable 3. Both axes must be properly labeled. If necessary, measurement units must be included. Two ways to show a measurement with units are shown below: Length of fish in cm Length of fish (cm) 4. Increment marks on the “X” and “Y” axes should be evenly spaced and numbered properly. The example on the left is correct. 1 2 3 1 2 3 not spaced properly 5. Give the graph a descriptive title. 4 WHAT GRAPH SHOULD YOU USE? Line Graph: Line graphs are used to show trends or relationships between data. They often demonstrate data collected over time. Pie graph (chart): Pie graphs or charts show how parts make up a whole. Percentages are often shown in pie graphs. Bar graph: Bar graphs are used are typically used to display data that show “how many” of something such as the results of a survey, populations, etc. If you’ve counted items in a category during your data collecting, it is likely the data will be displayed on a bar graph. 5 Honors Biology Summer Assignment Graphing Activity: 1. When looking at the set of data below, give a detailed explanation on how and why you would decide to create either a line graph or a bar graph. Type of Graph: ___________________________________ Why?: 2. Given the following data table, create a graph that displays the data in the correct scientific manner. The graph must be created using graph paper. No computerized graphs accepted.
