Geometry
A 2D shape is flat with 2 dimensions; a 3D shape is more defined and realistic and has 3 dimensions
What food is made in a similar way to milk plastic?
Cheese
Identify 3 areas of the body where we have joints
Jaw, neck, shoulders, elbows, fingers, hips, knees. ankles, and toes
Identify 3 similarities between all of the Gas Giants
They all have rings, cold temperatures, and windy storms and are made of gas
What is geometry?
The study of shapes
What are the 2 dimensions in a 2D shape?
Length and width
What is the purpose of the cheesecloth?
To separate the solid and liquid components of cheese
What is a joint and how is it beneficial?
A joint is a pocket of air between two bones that helps us bend our bodies and move more easily
In what two significant ways is Earth different from the other planets in our solar system?
1. Only planet with life; 2. Only planet with liquid water
What does it mean if an item is "biodegradable"?
It is made of natural ingredients and can easily decompose
What third dimension does a 3D shape have that a 2D shape does not?
Height
What happens when you add a lot of "activator", like contact solution, to a slime mixture?
It acts more like a solid
What two items are tendons attached to within the body?
Bones and muscles
Why was Pluto demoted to the status of dwarf planet?
It is too small with too weak a gravitational pull and is thus unable to clear the area around it of debris
What is a polymer?
A chain of a single molecule repeating
When speaking about geometry, what is a "net"?
A 2D representation of a 3D shape
What two items are formed when we combine warm milk and vinegar?
Curds (solid) and whey (liquid)
When do our muscles "bulge" and why?
Muscles bulge when we bend our bodies at the joints. Our muscles are constricting to allow our tendons to move our bones
What are the 3 criteria necessary for a celestial body to be considered a planet?
1. Spherical shape; 2. Orbits the Sun; 3. Clears the area of asteroids and other debris
How is dissection beneficial?
It helps us to see how things work internally
What is the difference between a pyramid and a tetrahedron?
A pyramid has a square base with triangular faces; a tetrahedron has a triangular base with triangular faces
Chemically, how are curds formed?
Proteins in the milk bond with the vinegar
Explain how our "robot" hand simulates the internal movement of out own hands
The robot hand has strings pulling on paper to show movement- our own hand has tendons that are attached to bones; when we pull the strings on the robot hand, it simulates how our muscles pull our tendons to help our bones move at the jointd
Explain the reason for Mercury's extreme changes in temperature
Mercury has a thin atmosphere that does not hold in heat- thus it is extremely hot when facing the Sun, but extremely cold when facing away from it
What is the greenhouse effect?
The greenhouse effect occurs when greenhouse gases, like carbon dioxide, make up the atmosphere surrounding a planet. These gases keep the planet warm by trapping in the heat from the Sun's rays
