Science T/W
What does CER stand for?
Claim, Evidence and Reasoning!
What does experimental probability mean?
It tells us how likely something is to happen based on the results of an experiment.
Name 2 safety expectations for our slime lab.
Wash your hands before and after lab, keep all materials away from the face, keep slime and all ingredients on the table, help clean up after, follow all directions, clear tables before lab
What is culture?
Characteristics and knowledge of a particular group of people, like language, religion, food, social habits, music, and art
What are some reasons for the differences between theoretical and experimental probability?
Sample size, randomness, human error
Where do synthetic and natural materials come from?
Natural resources
Can we eliminate human error through machine experiments?
No, because machine experiments can still lead to human error, because humans program machines.
Do you think the convenience of synthetic materials outweigh their environmental impacts?
Student responses
Describe where Eastern Woodland people are on a map of the United States.
Great Lakes to the Gulf of Mexico
Jimmy thinks that if he rolls a dice (20-sided die) 20 times, he will roll a two 20 times. What type of probability is he thinking of, and does this sound mathematically correct? Why or why not?
Theoretical probability and no. It should be 1/20.
What are 2 synthetic materials that you use or see in your life?
What is the difference between experimental and theoretical probability?
Experimental probability is based on actual, observed events that happen, while theoretical probability is based on mathematical expectation.
What is the key difference between slime and oobleck that makes one synthetic and the other natural?
Both are made from natural resources, but the slime had been chemically changed.
What were the two major language groups in the (Northeastern) Eastern Woodland group? Hint: Starts with A (or H) and I.
Algonquian (Haudenosaunee) and Iroquois
Jimmy flipped a coin 100 times, and he got heads 72 times. What type of probability is this, and why did this happen?
Experimental probability and due to human error and/or low sample size.
Do you think synthetic or natural materials are better? Why or why not?
Varies
Is there a way for the results of an experiment to always match theoretical probability?
Generally not possible due to chance. Every little thing would have to be kept the same.
How do synthetic materials impact the environment?
High fossil fuel dependence, don't biodegrade (don't decay naturally, which means they stay in the environment), a lot of pollution, deforestation, and land use
Name one thing you learned about the culture of Eastern Woodland people from the lesson.
Varies.
Which probability (theoretical or experimental) do you think is more reliable? Why?
Student responses
How is plastic made?
Petroleum (a natural resource) is processed and chemically changed to eventually become plastic.
Why can theoretical probability and experimental probability be different?
Human error!
Is glass natural or synthetic?
Natural material! It comes from sand that has been melted and cooled, but the chemical makeup is the same.
What is the importance of preserving historical items like wampum belts?
Sacred, living records of Indigenous history and treaties, rather than just simply artifacts.
What does the law of large numbers mean in math?
As the number of trials increases, the result approaches the theoretical probability.
