Photosynthesis

100

These 3 ingredients are required for plants to undergo photosynthesis.

What are sunlight, water, and carbon dioxide?

200

This gas is released by plants during photosynthesis?

What is oxygen?

300

All energy comes from this.

What is the sun?

400

DAILY DOUBLE (800 Points): These tiny holes found on the leaf of a plant are responsible for taking in carbon dioxide.

What are stomata?

500

6CO2 + 6H2O + Light Energy = C₆H₁₂O₆ + 6O₂

What is the chemical formula for photosynthesis?

Food Chains + Food Webs

100

These organisms are responsible for creating transferrable energy for other organisms.

What are producers?

200

Consume both plants and animals.

What are omnivores?

300

This is created when you combine multiple food chains.

What is a food web?

400

These organisms are responsible for breaking down decaying matter and returning nutrients to the soil.

What are decomposers?

500

This is an organism that sits on the top of the food chain and has no natural predators.

What is an apex predator?

Physical and Chemical Changes

100

A type of change in which no new matter is created.

What is a physical change?

200

A type of change in which new matter is created.

What is a chemical change?

300

This type of change results when you leave a bicycle out in the weather over time, causing the metal parts to rust.

What is a chemical change?

400

This type of change takes place when you mix eggs, flour, milk, and sugar to make a cake batter.

What is a physical change?

500

This type of change occurs when you take cake batter and bake it in the oven.

A chemical change.

Mixtures and Solutions

100

A bag of jelly beans.

What is a mixture?

200

Lemonade.

What is a solution?

300

Trail Mix.

What is a mixture?

400

A special type of mixture where all ingredients dissolve and spread out evenly.

What is a solution?

500

This method is used to separate water and sugar.

What is evaporation?

Laws of Motion

100

Force = Mass x Acceleration. States that heavier objects require more force to move.

What is Newton's 2nd Law of Motion?

200

The Law of Intertia. States that an object in motion will remain in motion and an object at rest will remain at rest unless they are acted upon by a force.

What is Newton's 1st Law of Motion?

300

Action and Reaction. States that for every action there is an equal and opposite reaction.

What is Newton's 3rd Law of Motion?

400

This law of motion deals with the Earth orbiting the sun.

Newton's 1st Law of Motion. 

500

This law of motion is present when a rocket launches into space.

What is Newton's 3rd Law of Motion?

600

This force is present when the surfaces of objects come in contact with each other. 

What is friction?

700

This force is responsible for Earth not floating off into space.

What is gravity?
