Section 1
Draw a model that represents:
1 molecule with 10 atoms
See boards (10 atoms connected by bonds)
Draw a model that shows two waves:
Wave TWO must have a HIGHER amplitude
See boards- wave two should have larger waves in height
Organ systems are made of _________ which are composed of specialized cells that work together and form a ________
1) organs
2) tissues
What happens to the light particles as it leaves a flashlight once turned on?
The light particles spread out at a certain angle and continues to travel. Can be reflected or absorbed depending on the material it hits.
Describe how you know when a rock layer is the oldest
The oldest rock layer will be at the bottom and some or all of the organism fossils may not be present in other rock layers.
Aspen Trees ----- Elk ------- Wolves is an example of a food chain. A food chain represents the flow of _____
Gravitational force
How does a smooth vs rough surface affect the way a ball will roll?
Smooth- less friction, faster
Rough- more friction, slower, more difficult
In a model of Earth and it's solar system, what is an error in that model?
The model is only a representation! It does not display actual distances or sizes of objects.
How can you know that the environment of Earth has changed by the rock layers
The type of fossils (ocean/water organisms, land organisms)
As mass increases in an object, the kinetic energy of the object: increases/decreases
Increases
You mix two liquids together. The liquids are unknown but you want to determine if a chemical reaction occurred. When you mixed the two substances, bubbles were created. Could you hypothesize a chemical reaction occurred?
Yes, bubbles are an indication of a chemical reaction
Put the following in the correct order from longest distance to shortest distance:
1) Distance from Earth to Sun
2) Distance from Earth to Moon
3) Distance across our Solar System
4) Distance Across the Milky Way galaxy
Order:
Distance across Milky Way, Distance Across Solar System, Earth to Sun, Earth to Moon
Identify two organelles that are in plant cells but NOT animal cells
Chloroplast, chlorophyll, cell wall
A ball is being pushed with 5N to the right and 10N to the left. Which direction will the ball move?
The ball will move to the left because there is a force of 10N being pushed that direction which is more than the force of 5N to the right.
Teosinte seeds easily release from the stalk of the plant after they mature, would you hypothesis that they are more easily to reproduce or less likely to reproduce
They are likely to reproduce
Give an example of genetic modification
Genetic material can be transferred to one organism to another (it does not have to the same organism)
