Homework

Homework Pay attention next slide

The larger the island, the higher the number of species can be found on it . You will also find more resources, and it will have fewer extinctions including yourself. Copyright © 2024 SlideSpark LLC Large Small

On some small islands being small is better. Easier to survive. You need less food. Animals on these islands evolve to be smaller. There is still some debate over this issue. Copyright © 2024 SlideSpark LLC

This buffalo is the one found on islands

Pay attention next slide

The greater the distance, the fewer the number of mainland species will successfully make the journey. Thus larger islands close to the mainland will have more migrations than small islands that are very far away. Copyright © 2024 SlideSpark LLC

Which island will get the most migrations? Let’s find out with a simulation. Keep track of the number of migrations that hit the Island using the check system . Use a ramp, simulated islands, and round balls for coconuts. Copyright © 2024 SlideSpark LLC M A I N L A ND A B C D

Please create the following spreadsheet. Island Number of migrations A B C D

View of simulation from above. A B C D R A M P X Flat Bumpers Create a spinning dropping method that drops ball randomly. The goal is a random spin off of the flat surface and down the ramp to an island.

It is very important to use the spin method in the pitcher so that this is a random journey across the ocean, and not bowling for Island B.

Which Island had the most migrations? Answer: Island A. This island should have more species because it parallels the mainland while the other island does not. The journey to reach this island is more likely. Copyright © 2024 SlideSpark LLC M A I N L A N D A B C D

Which Island had the most migrations? D = Least likely to receive migrations because it’s so remote and small. Island may also suffer many extinction events because it’s so small. Copyright © 2024 SlideSpark LLC M A I N L A N D A B C D

Activity! Place the following words next to the correct yellow / red Island. Green = mainland A - High level of migrations C - High level of extinctions B - Small level of migrations D – Low level of extinctions Copyright © 2024 SlideSpark LLC 1 2 3 4

Activity! Place the following words next to the correct yellow / red Island. Green = mainland A - High level of migrations C – Island Hopping B – Medium level of migrations D – High level of extinctions Copyright © 2024 SlideSpark LLC 1 2 3 4

Preparation for two weeks from now. Please set up three containers with pond or stream water. Have one be control with just water, and then have the next three have increasing amounts of nutrients / fertilizer. Label each one and place near light source. Control Low Medium High
