15
What is the difference in a physical and chemical
change?

• A A physical change makes a new substance, a
  chemical does not.

• B A physical change stays the same! A chemical
  change makes a new substance!

• D A chemical change is indicated only by a
  change of temperature.

• C They both remain the same.

Bonus!! What are the indicators of these changes?
16
INCORRECT!
TRY AGAIN!
17
Correct!
A chemical change is a change in which both the
physical and chemical properties of the original
substance are changed. The new substance has new
physical and chemical properties. Examples New
substance, gases formed, flammability, rusting.
A physical change stays the same
substance! Examples Color, shape, smell,
density, melting, freezing, boiling point,
buoyancy, viscosity, hardness and specific heat.
18
Where do plants get their energy from to make
glucose?

• A The Sun

Click on the letter of the correct answer

• B Water

• D Soil

• C Carbon Dioxide

BONUS! Is photosynthesis a chemical reaction?
Why?
19
INCORRECT!
TRY AGAIN!
20
Photosynthesis
Correct!
6CO2 6H2O energy (sun) ? C6H12O6
6O2 Carbon dioxide reacts with water and
sunlight to form glucose (a sugar/food) and
oxygen. It makes a new substance!
21
Which organism transfer more energy to other
organisms?

• A Snapper

• B Diatoms

• D Octopus

• C Bull carp

Bonus! What would an energy pyramid look like for
this food web?

What is the difference between a plant and animal
cell?

• A The nucleus

• B The vacuole

• D Roots

• C Cell wall and chloroplast

BONUS! What is turgor pressure?
28
INCORRECT!
TRY AGAIN!
29
The cell wall and the chloroplast.
Correct!
Turgor pressure is the Amount of pressure that
the water puts on the cell wall to keep
the plant rigid and upright.
30
What is the most likely connection between the
extinction of the dinosaurs and volcanic
eruptions?

• A Global warming

• B Dust filled the oceans.

• D Global cooling by the ash blocking the
  sunlight.

• C Lava covered the dinosaurs.

Bonus! What is the other theory for the
extinction of the dinosaurs?
31
INCORRECT!
TRY AGAIN!
32
The ash from the volcano or dust from a meteorite
strike blocked the sunlight, killing the
herbivores first, then the carnivores, leaving
animals 65lbs or smaller alive. This is known as
global cooling.
Correct!

What is the theory of global warming?

• A Increased volcano activity

• B Movement of the Earth out of orbit

• D Plate Tectonics

• C Over use of Fossil Fuels

Bonus! What are three types of fossil fuels?
37
INCORRECT!
TRY AGAIN!
38
Correct!
Global Warming!
Overuse of fossil fuels has increased the carbon
dioxide in the air. The increase of carbon
dioxide is adding to the greenhouse effect
causing a imbalance of the gas. This is breaking
down the ozone, allowing more of the UV rays to
enter the Earths atmosphere and heat up the
planet.
