Agriscience Project Description, Report Outline, and Grading Rubric

Project Description:

You need to do a science project that fits into one of the following categories: Animal Systems, Environmental Services/Natural Resource Systems, Food Products and Processing Systems, Plant Systems, Social Science, or Power, Structural and Technical Systems. Be creative! If you need help coming up with ideas, Miss Baadsgaard can point you in the right direction. You need to complete 6 steps to get credit for this project:

1.Question & Hypothesis:

The first thing you need to do is come up with a question. (Example: Does a certain type of fertilizer help geraniums grow better? Hypothesis: Scott’s 20-20-20 is the best fertilizer for geraniums.)

My project/question is:______

______

My Hypothesis for my project is:______

______

Pictures: Make sure you are taking PICTURES of your project regularly! If the progress of your project happens daily, you should be taking pictures daily! At minimum, you should be taking pictures AT LEAST ONCE A WEEK! You need AT LEAST 6 pictures and you should be in most of the pictures. Also, make sure you’re recording data.

2.Title Page

Next complete your title page. Your title page should include:

· A Short Title (Make it fun if you can!) (Less than 50 characters)

· A short description of your project (No more than 3 lines)

· Division area (select from the options on the back of this sheet)

· Your Name

3.Literature Review:

Then you need to do some background research. You need to have AT LEAST 3 RELIABLE SOURCES. You can use Wikipedia to help you answer your own questions, but you CANNOT USE WIKIPEDIA AS A RELIABLE SOURCE. Here is a description of what your literature review should include:

Literature Review

[Literature Review should detail what information currently exists concerning the research project. Information listed should be literature used in the research. Material cited would include articles about similar studies, similar research methods, history of the research area and other items that support the current knowledge base for the topic and how the project might complement existing information.]

4.Materials and Methods:

After you have your question, hypothesis and research completed, you’ll need to compile a list of items and materials you will need to complete your project. Make sure you include prices for these items! You will also need to write how you will be completing this experiment. (Who, What, When, Where, Why and How).

5. Experiment: Complete your experiment! TIP: Make sure you are keeping track of pictures and data!!

6. Report:

Your report is going to be long! Luckily, because you have been following the instructions above, you already have most of it done! Your report needs to be typed, have complete sentences and proper grammar. Include the following IN THIS ORDER in your report. Make sure you read the descriptions of each item to make sure you have done everything you need to do to get full points!

Project Title Page: See above description!
Abstract: [Abstract is brief and concisely describes the purpose, methods, results, and conclusion. Abstract does not include the title or cited references. It should be no longer than one page. Arrangement of information should make the purpose, procedure, and conclusion clear.]
Introduction: [Introduction should answer the question “Why was the work done?” It should clearly state the problem that justifies conducting the research and build a need for the importance of the research, the purpose of the research, findings of earlier work, and the general approach and objectives. Citations should be used in this section.]
Literature Review: See above description!
Materials and Methods: See above description!
Results: [This section should be a written (paragraph form) summary of the results the project has produced. Trends and relationships are clearly addressed, but no conclusions should be made. This section should include data (tables, figures) that can stand alone and include headings, labels, and proper units of measure. A caption for a table is placed above the table and a caption for a figure is placed below a figure. Both are at least two point sizes smaller then the point size of the figure’s text and are single spaced.]
Discussion and Conclusions: [This section should show that the conclusions were drawn from the results of the study and how the results relate to the hypothesis. It should contain a brief recap of the results and show how the results were a foundation for the study. Explanations should be clear if the results were not as expected. Sound reasoning is used to make conclusions that rely on both literature and results. Discussions should reference facts and figures form results section. Conclusion should be editorial in nature.]
References: [References should contain significant, published, and relevant sources. APA style recognized citation is used throughout the report. References are worth 5 points.]

Greek and Latin Roots

Students often struggle with science content due to lack of vocabulary comprehension. Science vocabulary terms are often derived from languages other than English, most commonly Greek and Latin roots. By learning some basic Latin and Greek roots, you will gain a broader understanding of science word’s meanings.

A root is a word that:

· Can stand by itself

· And have meaning

Some examples:

Hydrophobic hydrophilic Chlorophyll

Hydros – water hydros – water Cloros – Green

Phobia – fear philos – friend phullon – leaf

Fill in the word meaning below. You will be quizzed next time on several of these:

a- / Iso-
anti- / -lysis
-ase / Meso-
bi- / Mono-
bio- / -morph
Cardio- / -ose
Cerebr- / Peri-
Chloro- / Phago-
-cide / Pheno -
Co- or com- / -philic
di- / -phobic
Diplo- / Photo-
Ecto- / -pod
Endo- / Poly-
-gram / Re-
Hetero- / Tel- or telo-
Homo- / -therm
Hydro- / Trans-
Hyper- / -troph
Hypo- / Uni-
Pro - / Karyote
Eu

Can You Graph Lab?

Station 1: GUM MASS LOST

1- Hypothesis: Which kind of gum will lose the most mass after chewing?

2- Get your gum

3- Weigh your piece of gum WITH THE WRAPPER ON.

4. Remove your gum from your wrapper (SAVE the wrapper for later).

5. Chew your gum as you finish the remaining stations and then weigh your gum AFTER chewing.

Data Table
Type of Gum / Start Weight / Finish Weight / Difference / Ratio / % of Sugar
(formulas) / In Grams / In Grams / Start- Finish / Diff. / Start / Ratio x 100
YOURS
Lab Partner 1
Lab Partner 2

Make an appropriate graph that shows which gum has the most sweetener:

Based upon your data, make an inference: Which type of gum lost the most mass and WHY?

Independent & Dependent Variables

______

Name:______Date:______Per:______

Graphing Practice

Part A: Trees of the Rain Forest

The Rain Forest is made up of layers that are called the canopy. Each tree in the forest will occupy different part of the canopy. The sun will only fully penetrate the upper parts of the canopy. Draw a graph of this data.

Analyze and Conclude

1. Evaluate What type of graph did you use and why? Identify the dependent and independent variables.

2. Interpret Data How many and what types of trees are found in each of the rain-forest layers? Suggest a way to highlight this information on your graph.

3. Draw a picture: label your picture FOREST CANOPY. Fill in the types of trees in the correct portion of the canopy by labelling the canopy with UPPER, MIDDLE UPPER, MIDDLE LOWER, and LOWER.

Part B: Elements in Human Body

***You may want to group some data together on your graph or chart***

4. What type of graph will you use and why? Are there variables in the graph?

5. Interpret Data: List the elements in the human body that are at least 1 percent of mass. Overall, what percent of body mass do these elements add up to? Use a pie chart to graph the data on the chart.

6. Most of the mass of the human body is water. The mass of water can vary from 60 to 90 percent. Do the data support this fact? Why or why not? Hint: Think of the chemical formula for water.

Part C: Hare and Lynx Pelts

One of the best-known examples of a population study came from the records of a fur-trading company in Canada. The Hudson’s Bay Company (HBC) kept records of its catches of hare and lynx over a long period of time. Charles Elton, an English ecologist, used the records to hypothesize about cycles in animal populations. The table shows the HBC data for hares and lynx pelts taken between 1845 and 1899.

7. USING THE DATA, ADD A LINE FOR THE LYNX TO THE EXISTING GRAPH

8. What trend do you see that exist between the lynx and the hare populations?

9. If you were to add a third line for coyotes, how do you think it would affect the two lines that already exist on the graph? Use data to support your answer

Part D: Fat Content of Sandwiches

10. The table compares the fat content and number of Calories in some common sandwiches. Although the serving sizes vary, you should be able to draw some conclusions about the relationship between fat content and number of Calories. You will use the data to make a graph with a line of best fit.

11. What type of graph did you use??

12. What did you use as the independent variable and why??

13. Put a line of best fit on the graph

14. What correlation do you see between the amount of fat and the calories of a sandwich??

Add the following points on the graph where you think they would go and label them

15. Grilled chicken sandwich

16. Veggie Sandwich

17. Bacon and Cheese

Food Chains and Webs --- "What's for dinner?"

Every organism needs to obtain energy in order to live. For example, plants get energy from the sun, some animals eat plants, and some animals eat other animals.

A food chain is the sequence of who eats whom in a biological community (an ecosystem) to obtain nutrition. A food chain starts with the primary energy source, usually the sun or boiling-hot deep sea vents. The next link in the chain is an organism that makes its own food from the primary energy source -- an example is photosynthetic plants that make their own food from sunlight (using a process called photosynthesis) and chemosynthetic bacteria that make their food energy from chemicals in hydrothermal vents. These are called autotrophs or primary producers.

Food Chain Questions

1. What travels through a food chain or web?

2. What is the ultimate energy for all life on Earth?

3. The 1st organism in a food chain must always be what type of organism?

4. Make a simple food chain with a producer and 3 consumers NOT shown above.

The arrows in a food chain show the flow of energy, from the sun or hydrothermal vent to a top predator. As the energy flows from organism to organism, energy is lost at each step. A network of many food chains is called a food web. Don’t forget that when any organism dies, it is eventually eaten by detrivores (like vultures, worms and crabs) and broken down by decomposers (mostly bacteria and fungi), and the exchange of energy continues.

FOOD WEB (create on the next page):

1) Choose an organism from your favorite biome. Draw (or write) that organism in the middle of your paper.

2) With your chosen organism, create your food web with at least 10 organisms.

3) At the bottom of your food web, create 3 separate food chains with at least 4 organisms in each that show the transfer of energy from one trophic level to the next. Use your knowledge of an energy pyramid to do this. (For example: Grass (10,000 J) Grasshopper (1,000 J) Mouse (100 J) Snake (10 J)

Here is the rubric for grading your food web READ THIS:

· Included arrows to show energy flow (Are they pointed in the correct direction?)

· Labeled each organism as Producer; Primary Consumer; Secondary Consumer; Tertiary Consumer or Quaternary Consumer.
