7th Grade Science

INTRODUCTION Cities and cells, what do these two things have in common? There is a lot more than you may first think. How are plant cells different from animal cells? How do materials move in and out of a cell? In this web quest, you will be finding the answers to these questions.

Cities are busy places with each building specializing in a particular service or activity. Each building provides services that are necessary for the city's continued existence. Cells are no different. Each part of a cell, like each building in a city, specializes in an activity or service that benefits the cell and organism as a whole. You are a city planner. You must make sure that the "cell city" that you build has all of the parts, goods and services necessary for the "cell city's" survival.

Be sure to use the talents of everyone in your group. At the end of the web quest, you will build your own cell. Be sure to look at the Evaluation page. At the end of the unit, you will be evaluating yourself as well as the other group members. I will be filling out one of the rubrics for you as a grade. I will take into consideration what your team mates have to say. Look at the rubric now so you know what you are being graded on.

Questions - These questions tell you what you will learn. - You will have to answer these questions at the end of Task Describe the structures and functions of the organelles in a cell. 2. Compare and contrast plant and animal cells. 3. Describe and discuss how a cell maintains homeostasis.

CELL CITY WEBQUEST TASK ONE

Instructions for Task 1 1.Create a chart that is 5 columns across the top and 13 rows down the side. The five columns across the top are: CELL PART DESCRIPTION FUNCTION PLANT/ANIMAL/BOTH REPRESENTIVE CITY BUILDING

The 13 rows down the side of the paper are: CYTOPLASMMITOCHONDRION NUCLEUSVACUOLE NUCLEOLUSLYSOSOME CHROMOSOMESCHLOROPLAST ENDOPLASMIC RETICULUMGOLGI COMPLEX RIBOSOMES CELL WALL CELL MEMBRANE

2.Divide the organelles among the members of your group. 3.Using the websites on the resource page, research your organelles and fill in the chart. 4.When you are finished, return to your group and exchange research information. When everyone has completed a chart, move on to Task 2.

CELL WEBQUEST TASK 2

Instructions for Task 2 1.Using the chart that you made in Task 1, on an index card, you will draw, label and color the 13 organelles. Assign each group member a few of the organelles to complete. 2.Return to your group and sort the organelles into three piles: Plant Cell Parts, Animal Cell Parts, and the parts that appear in both types of cells.

3.Draw a large Double Bubble Mind Map on bulletin board paper. Label one center circle “Plant Cell”, the other center circle “Animal Cell” and the center bubbles “Both”. 4. Glue the completed index cards to the Double Bubble Mind Map in the correct places.

Instructions for Task 3 In this task, you have a few choices. Each activity on the Task 3 activity sheet, has been assigned a specific number of points. You may choose any of the activities, as long as the points add up to a total of 50.

CELL CITY WEBQUEST Task 4

Think of a City How does it operate? Who protects the city? Who runs the city? How does the city manage its trash? How does the city get food? How does the city get its power? How do you know when you are in the city limits?

A cell can be compared to a city! Each part of the cell has its own function or purpose. The parts of the cell can be compared to the parts of a city based on their similar purpose.

Let’s compare! Cell Part A.Cell B.Cell Membrane C.Cytoplasm D.Nucleus E.Nuclear Membrane F.Ribosomes G.Endoplasmic Reticulum H.Golgi Bodies I.Mitochondria J.Lysosomes City Analogy A.City B.City Limits C.Environment D.City Hall E.Police Force F.Factories & Workers G.Highway or Roads H.Post Office or UPS I.Power Plant J.Recycling Plant or Waste Management We are going to label your parts of a cell page together

A. Cell = City B. C. D. E. F. G. H. I. J.

Create a City Cell Analogy You can use a city or any other place (amusement park, country, the mall). Can be a fictional place. Steps of the Project: – Step 1: Brainstorm on the cell parts and what you can draw to represent each part. Use the Parts of a Cell Page to help you. – Step 2: Draw a picture of your city. Label each “cell” part of the city with a letter A through J. – Step 3: Create a legend or map key in the corner and explain what A – J represent. Ex: D = Town Hall – Step 4: On a separate piece of paper, in complete sentences, write your analogies. This will explain why you selected each part of your city to represent the part of the cell and what function they both share.

Think of the place you want to draw. Be creative. Create an analogy for each cell part. Write your ideas on your Parts of a Cell page. A. Cell = City B. Cell Membrane = City limits C. Cytoplasm = Environment D. Nucleus = Town Hall E. Nuclear Membrane = Police F. Ribosomes = Factory G. Endoplasmic Reticulum = Roads H. Golgi Bodies = Post Office I. Mitochondria = Power Plant J. Lysosomes = Recycling Plant

Create your map and legend. Draw your city. Pencil first, then crayons or colored pencils. No markers. Label each part on your city A – J. Circle the letter. Create a map legend or key in the corner of your map which lists the letters A-J and identifies the name of each place. – Example. A= Far Far Away; B=city limits

Legend A: Far Far Away B: Brick Wall C: Environment D: Shrek’s Castle E: Puss-n-boots Security Service F: Gingerbread Man’s Cookie Factory G: Roads H: 3 Blind Mice Delivery Service I: Dragon Power Service (DPS) J: Donkey Recycling A B C D E F H J I G

Explain why you chose the items to represent each cell part. List the letters A-J For each letter: – State the name of the city place – The name of the cell part it corresponds to – Why you selected that item to represent the cell part Must be in complete sentences. – Example: B: The town hall represents the nucleus because its function is to control the town’s activities On notebook paper.

Final Product: Your analogies must be in complete sentences and stapled/glued to the back of your map. Your map/picture must be neat, colorful, correctly labeled, and have a legend or key. Use pencil first then color. Be creative! Have fun with it. Past examples included underwater cities, prehistoric cities, a skate park, amusement parks, etc…
