FOSSWEB Independent Learning Activity Booklet
FOSSWEB Independent Learning Activity Booklet Topic: Populations and Ecosystems The course explores ecosystems as the largest organizational unit of life on Earth, defined by its physical environment and the organisms that live in the physical environment. Students learn that every organism has a role to play in its ecosystem and has structures and behaviors that allow it to survive. Students raise populations of organisms to discover population dynamics and interactions over a range of conditions. They learn that food is the source of energy used by all life forms in all ecosystems to conduct life processes. Reproduction, including limiting factors, heredity and natural selection are explored as ways to understand both the similarity and the variation within and between species.

Close out of this window and go back to the main menu page From here select the cage that says WalkingStick Predation. From the smaller menu select Eat Insects. Choose 30 seconds to eat insects When the time is up, check your results and complete the table below: Eaten Brown Green-brown Green Survived Try the activity again and see if you can improve your results. Complete the table below with you new results. Eaten Brown Green-brown Green Survived Q1. Explain your results after your second attempt. Did you improve? Why do you think this is so?
Close out the window and go back to the main menu. From there click on WalkingStick Predation and select the second option from the smaller menu called Find Insects in Three Environments Choose 30 seconds to eat insects Select the Woodchips environment. When your time is up click on results and fill out the table below: Starting population 1 Brown Green-Brown Green Initial Eaten Survived Initial Eaten Survived Initial Eaten Survived 2 3 4 5 Press the continue button at the bottom of the screen and then next generation to have another go. Keep on filling in your table as you complete each trial. Q2. Analysis: Did you results improve with each new generation? Why/ Why not? (Explain your answer) Next select the Bamboo environment and fill out the table below: Starting population 1 Brown Green-Brown Green Initial Eaten Survived Initial Eaten Survived Initial Eaten Survived 2 3 4 5
Q3. Have a look at your results tables. Which environment allowed more Brown insects to survive? Q4. Why do you think this is so? Q5. Which environment allowed more Green insects to survive? Q6. Why do you think this is so? Press the close button to close the window. Go back to the main menu to select Larkeys. From here watch the Larkey Breeding Video When the video is finished go back to the main menu and select Larkeys. From here select the second option from the smaller menu titled Offspring Genotype and Phenotype Some important Information about genetics! How an individual looks and what their genetic code is sometimes do not match up. This is the difference between genotype and phenotype. The genotype is the actual genetic make up of an individual. The phenotype is what that individual looks like. Traits that show up more often are called dominant traits. Traits that show up less often are called recessive traits. Each trait is represented by two genes (capital letters showing the gene is dominant, lower case letters representing recessive). You only need one dominant gene in the pair to make the trait dominant. In this activity the traits are: Appendage, Eye, Fur and Tail For example: Eye Colour EE (the trait is dominant and the colour is RED) ee (the trait is recessive and the colour is GREY) Ee (the trait is dominant but the animal is a genetic hybrid or mix, the eye colour would still be RED)
Click on Genetics Key at the bottom of the page. Q7. Determine what the animal will look like by filling out the tables below: Fur Pattern Genotype Phenotype FF Ff ff Genotype TT Tt tt Tail Shape Phenotype Appendages Genotype Phenotype AA Aa aa The combination of genetic information from each parent is determined by using punnet squares. A punnet square is a diagram that can predict the outcome of a breeding experiment. For example if we wanted to determine what type of appendages the offspring of two Larkeys could have, we can place this information in the punnet square to find out. Father s genotype: AA (short) Mother s genotype: Aa (short) Mother s genotype here A a Father s genotype here A A
In the top left hand square, you place one gene directly above the box (from the mother) and one gene directly to the left of the box (from the father). AA In the top right hand square you pace the gene directly above and the gene directly to the left. AA aa Continue this process until all the squares are filled. Now you can look at the possible genotypes of the offspring. If this mother and father Larkey have a baby what is the chance (out of 4) that the baby will be: AA What is it s phenotype (what would it look like)? Aa What is it s phenotype (what would it look like)? aa What is it s phenotype (what would it look like)? Now that you understand a bit more about genetics. Push the breed em button and you should have this screen pop up: This is the mother s genetic information This is the father s info
Q8. Complete the following table Feature Appendage Genotype (1 gene from mum and 1 gene from dad) Phenotype Eye Fur Tail Q9. In the box below, draw a picture of what this baby Larkey looks like. Q10. Continue to work through the five examples. When you have finished look at your results. How many breeding activities did you get correct? Congratulations! You have now finished the online component of Populations and Ecosystems. Please complete the following two activities below. Activity 1: Use the information you have collected about rainfall from all the different ecosystems and create a graph comparing each system. Use the grid on the following page to create your graph.
Activity 2: Select an ecosystem that you found interesting or would like to know more about and create a podcast about that ecosystem. In your podcast include information about: A) Where it is located, B) Climate, C) The average rainfall it receives each year, D) Select three plants that exist in your ecosystem and describe two adaptations for each plant that helps it to survive in the ecosystem. E) Also include information about five animals that live in this ecosystem and explain two (or more) adaptations that each animal has which allows it to survive in this environment. F) Include a food chain that would exist in this particular ecosystem. You must identify the primary producers, primary consumers, secondary consumers, tertiary consumers (optional) and the decomposers. Some resources to help you: www.misssimpson.com Go to the life and living page and select Feeding Relationships to learn about food chains.
