7th & 8th Science - Work on your Conclusion.  Here are things that should be included:

• An accurate reaction to the hypothesis as compared to the resulting data; 
• Explains whether the experiment results were/were not supported by the research; 
• Inferences are suggested to describe why the results may have happened (include science concepts); 
• Provides information about what was learned as a result of this project; 
• Gives explanations to tell what the resulting data 'means'; 
• The conclusion is clear and helps the observer understand "what happened/and why”; 
• Project shows a great deal of thoroughness;
• Shows awareness of reliability / accuracy of data; 
• Ideas for a future related study are proposed

Science Concepts

These are science concepts that would be great to include in your science fair papers if they apply to your project:



Abiotic - something that is not alive

Absorption - light energy being transferred to objects they interact with

Acceleration - the rate at which velocity changes

Acid - a chemical that has a pH level of less than 7

Adaptation - a characteristic of an organism’s ability to change in order to survive in its environment

Archimedes’ principle - when an object is placed in a liquid, the liquid will displace an equal amount of fluid as the volume of the object

Atmospheric pressure - pressure on objects caused by the weight of the atmosphere

Base - a chemical that has a pH level of more than 7

Bernoulli’s principle - a moving fluid has less pressure than a stationary fluid; as the velocity of a fluid increases, the pressure of that fluid decreases

Biotic - something that is alive

Boiling - the change of state from a liquid to a gas throughout the liquid

Buoyant force - the force that a fluid will exert on an object within the fluid, pushing the object away from the fluid

Cerebellum - the part of the brain that keeps track of a body’s position

Cerebrum - the part of the brain that processes the senses, and controls voluntary movements and thoughts

Charles’ law - as the temperature of a gas increases, so does the volume of that gas

Chemical change - when one or more substances completely change into new substances with new properties


Chemical energy - the energy chemicals have because of their structure and ability to release energy when burned (like food being used by organisms)

Combustion - the process of burning

Controlled experiment - an experiment that tests only one factor at a time

Decibel - a unit to measure how loud different sounds are depending on pressure the sound waves cause

Density - the ratio of an objects mass and volume

Ecology - the study of the impact of interactions between organisms and their environment

Electricity - the energy of moving electrons which allows work to be done

Energy - the ability to do work

Force - a push or a pull exerted on an object

Friction - a force that opposes all motion because two surfaces are in contact

Gas - a form of matter without a definite shape or volume

Gravity - the force of attraction between objects due to their masses and the distance between them

Inertia - the tendency of an object to resist a change in motion

Innate behavior - a behavior that is influenced by genes and does not depend on the environment or on learning a skill

Kinetic energy - the energy of an object because of its motion

Law of conservation of energy - energy cannot be created or destroyed, but only transferred

Law of conservation of mass - mass cannot be created or destroyed in chemical or physical changes

Liquid - a state of matter with a definite volume but no definite shape

Machine - a device that makes work easier by changing the size or direction of a force

Malnutrition - a disorder resulting from not consuming the right combination of nutrients

Mass - the amount of matter in an object

Metabolism - a total of all the chemical processes that happen in an organism

Mineral - an element that is essential for good health

Newton’s 1st Law of Motion - objects at rest stay at rest, objects in motion stay in motion at a constant velocity unless acted upon by an outside force

Newton’s 2nd Law of Motion - the acceleration of an object depends on the object’s mass and the amount of force acting on the object (acceleration has a direct relationship with force and an inverse relationship with mass)

Newton’s 3rd Law of Motion - every action has an equal and opposite reaction

Nutrient - a substance that must be consumed or taken in by an organism to promote normal growth, maintenance, and repair

Pascal’s principle - within a fluid, equal force will be exerted in all directions

pH - a value that describes the chemical composition of a substance depending on its acidity or alkalinity


Placebo effect - a person’s attitude can affect an outcome; if a person takes a sugar pill thinking that it is medicine they might start feeling better just because they think they should be feeling better because they are taking medicine

Power - the rate at which work is done

Pressure - the amount of force exerted on a given amount of surface area

Projectile motion - the curved path of an object because of the force of gravity combining with the force of forward motion

Senses - ability for an organism to gather information about its environment using a central nervous system

Solid - the state of matter which has a definite shape and volume

Sound wave - waves that move through substances by vibrations and may be perceived by living organisms through hearing

Surface tension - the force of attraction at the surface of a liquid which minimizes the amount of surface area

Temperature - a measurement of the average kinetic energy of all the particles in an object

Viscosity - the resistance of flow in a fluid

Weight - a measurement of the gravitational force exerted on an object

Science Fair Calendar

1/8

7th Science - We read through pages 176 and 177 and had a guest speaker; Ms. Hays joined us for class and described her fossil collection and how she has found so many.  Thanks Ms. Hays!

7th Religion - Matthew 6 Questions due Thursday:

1. When have you seen someone do something "only for show," only to impress other people?  What could be done differently so their motivation is honor from God and not from people?
2. What are some things that ‘moth and rust’ could not destroy that are important to you?  What are the ‘best things that aren’t things’?
3. What are things that you are tempted to worry about, and how can you let go of those worries and give those situations to God?

1/7

8th Science - Read pages 153-156.  The section review (page 157) is due Thursday (1/10).
