Why are orangutans endangered?
We keep cutting down the rainforest to make oil palm plantations and lessening their livable spaces.

What kind of graph is this?
line graph

An independent variable is the variable that is
changing
100
An organism that makes its own food using sunlight
producer

Why is there no substitute for palm oil?
The other oils take too much land away from ecosystems
200
What is the trend of this graph?
increasing
200
The dependent variable is the variable that is
measured
200
An organism that eats both plants and animals

Why do farmers keep making oil palm plantations when they know it is hurting orangutans?
It is their only income and they need to support their families
300
Between what 2 months was the largest decrease?
April-May

It is important to have some controlled variables so that the experiment is
fair

An organism that eats a herbivore is a called what level of consumer?
secondary consumer

Why did the population size of the orangutans fluctuate during the 2nd simulation?
Births and deaths were added

A student investigates whether the concentration of salt in water affects the temperature at which the water freezes. The student prepares samples containing 0%, 2%, 4%, and 6% salt and records the freezing temperature of each sample.
What is the independent variable?
The concentration of salt in the water
400
What happens when a predator population gets larger in number?
prey die out/decrease and could possibly go extinct

How do our findings from the simulation activity packets help us design a solution to the oil palm problem?
We now know the bare minimum percentage of fruit trees to keep a stable population of orangutans to help us plan out land use in the rainforest.

Students test whether the type of surface affects how far a toy car travels. They release the same car from the same ramp onto carpet, tile, and wood.
