What is a scientific model?
A model is a simplified version of reality and can be used to better understand something or to test a hypothesis in science.
A model is a representation of an idea, an object, or a process that is used to describe and explain a phenomena that cannot be experienced directly.
Process model
Computer model
Three dimensional model
Equation model
Paper models
On a paper, draw a model to explain how the smoke particles make their way through the air.

Day #2
Intro to computer models
Paper model gallery walk
How do we validate an idea?
💡
Come up with an idea for how something works.
🌍
Design a way to model the idea.
🔍
Test the model and make observations.
📏
Compare observations from model with observations from real world.

What is a computer model?
A computer model is a representation of a real-life system or situation, such as the potential path of a hurricane or the potential spreading of COVID-19 in cities. A collection of rules or code is created--a computer program--and when it “runs” it allows us to study what might happen in real-life situations. A computer program has lots of variables or “parts” to change to see how they affect the outcome of whatever is being studied.

Modeling Challenges
#1: Make air move like wind
#2: Create continuous smoke
#3: Make the smoke and air interact
Challenge #1: Make air move like wind
Challenge #1: Make air move like wind
What’s inside this block?
Challenge #2: Create continuous smoke
Challenge #2: Create continuous smoke
IMPORTANT:
When create-smoke-particles is under Go, make sure a small number (1-10) particles are being created. Otherwise, the system will get overloaded because too many smoke particles are being created at each tick.
Challenge #3: Make the smoke and air interact

How do scientists collect data of wildfire smoke spread?
Analyze videos of wildfire near Lake Tahoe
Look at the fire in the middle.
What do you notice about the shape of the smoke spread and its path?
September 1st, 2021.
Analyze videos of wildfire near Lake Tahoe
Look at the fire in the middle.
What do you notice about the shape of the smoke spread and its path?
September 3rd, 2021.
Analyze videos of wildfire near Lake Tahoe
What do you notice about the shape of the smoke spread and its path?
Why do you think the two videos are different?
Analyze videos of wildfire near Lake Tahoe
Challenge: review your model and make sure it matches both days.
Hint: adjust simulation parameters to represent each day
Day #5

Key take-away
Wind: 45º, 50 km/h
Wind: 330º, 10 km/h
Key take-away
Wind: 45º, 50 km/h
Wind: 330º, 10 km/h
Key take-away
Modeling wind effect: making air particles follow wind direction & speed
Modeling diffusion: making smoke particles spread as they bounce off air & smoke (any) particles, adjusting their heading
Combined effect: smoke particles spread gets influenced by both diffusion and wind conditions
