| Concept/Vocabulary Word | Definition |
|---|---|
| aquatic | Having to do with water. |
| decomposer | An organism that gets its energy from breaking down decaying organic material. The role of decomposers is the recycling of nutrients throughout the ecosystem. |

Field Trip Reminder
We are excited to have High Touch High Tech Hands-On science coming to Herbert Akins during the fourth quarter! Our science field trip will be taking place on May 3rd, May 13th and May 20th. For more information on what our students will be doing, CLICK HERE FOR THE LINK!
The money isn’t due until April 19th, but it may be best to get your money in by the track-out, so you don’t forget! The field trips cost $24 for hours of hands on excitement, that will be directly related to our science EOG!!!
Thanks!!!
Here’s the letter that came home with the permission slip:
Dear 5th grade families,
The fifth grade team is excited to announce that our students will participate in 3 on campus field trips this spring. The amazing scientists from Science Fun for Everyone will work with our students to complete: Newton’s Lab, Storm Chasers and DNA Detectives.
In Newton’s Lab, the students will “defy” gravity and launch rockets into the air, design and race balloon cars, and compete in a cool catapult contest.
Storm Chasers will “dive” into the jet stream, use real weather instruments and even get “shocked” by safe lightening.
DNA Detectives will have the students using microscopes to learn about heredity and genes and create their own crazy creatures.
There will be 3 different days of labs, please see your child’s permission slip for exact dates (based on tracks).
The fee for these labs is $24.00. You may pay the sum all at once or spread it out for several installments. Please consult your teacher for payment options. All money is due to your child’s teacher by Friday, April 19th.
Each lab will include a make and take science activity and certificate per child.
Thank you for your support in bringing this fun and exciting opportunity to each of our students.
If you would like to sponsor a student through a “financial” scholarship, please let your teacher know.
Chaperones are welcome and are free of charge.
Sincerely,
The 5th Grade Team
Mrs. Henderson, Mrs. Miller, Mrs. Qualls,
Mrs. Penland and Mr. Pete
Essential Terminology: Motion & Design
-
acceleration: rate of increase of speed or velocity (example: accelerator pedal on a car)
- air resistance (drag): force of air pushing against the motion of an object
- balanced force: an object remains in place, no movement occurs
- control: part of an experiment that does not change, serves as the standard to compare other observations
- direction: the way the force is applied determines this way an object moves
- energy: ability to do work
- energy, kinetic: energy of motion (moving ball going down a ramp)
- energy, potential: stored energy (ball positioned at the top of the ramp)
- fair test: changing only one variable and keeping the other conditions the same
- force: any push or pull on an object
- friction: force that resists motion between two touching surfaces, slows things down and can also produce heat, acts in the opposite direction of the force
- gravity, gravitational force: force that brings objects toward earth
- inertia: the tendency of an object to resist a change in motion or keep doing what it is doing
- Note: the greater the mass of an object, the greater the inertia
- mass: how much matter an object contains
- momentum: force or speed of movement; mass in motion, example: a moving train has much more than a moving soccer ball
- Note: momentum = mass of an object x velocity
- (increasing the mass or speed increases the momentum)
- motion: an object changing position over time; change in position is measured by distance and time
- Newton’s 1st law of motion: *An object tends to stay at rest and an object tends to stay in motion with the same speed and in the same direction unless acted on by an unbalanced force.
- Objects tend to keep doing what they are doing.
- If the forces acting upon an object are balanced, the acceleration of that object will be zero (no motion).
- *also known as the “law of inertia”
- Newton’s 2nd law of motion: * Acceleration is always in the direction of the unbalanced force.
- *If you want something to accelerate faster, you need to decrease its mass.
- Acceleration of an object depends upon two variables—the net force acting upon the object and the mass of the object.
- Force = mass x acceleration or F = ma
- Newton’s 3rd law of motion: *Explains why forces act in pairs.
- For every action, there is an equal and opposite reaction.
- When one object exerts a force on a second object, the second object exerts the same amount of force back on the first object (but in the opposite direction).
- Equal forces acting in opposite directions create a net force of zero.
- Action and reaction forces are equal forces acting in opposite directions. The reason they can’t cancel each other out is because they are acting on different objects.
- propeller: two or more twisted blades that rotate around a central point or shaft (shaft: pipe or tube)
- recursive: consequential steps
- resistance: force pushing against the motion of an object
- speed (rate): distance divided by time (or d/t), example: 25 mph
- unbalanced force: motion occurs; the movement goes in the direction of the greater force (example: winning a tug-of-war game)
- validity: conducting a fair test
- variable: something in an experiment that can be changed
- velocity: speed with direction (ex.: 45 mph NW)
- weight: force of gravity pulling down on an object
- work: moving an object over a distance
