Welcome!

Welcome parents and students! We are back to school in full swing and ready to learn. I'm very excited to have each student in my class this year. I know God has put us together for a reason and I don't that job lightly. I will pray for your student and love them as much as I can. I hope we can have an excellent year. Seventh grade is a difficult time in every young person's life. There will be times they mess up, don't turn in work, forget supplies, etc. Hopefully we can work together as they mature and grow this year.

 Please do no hesitate to email me. It is the fastest way to communicate with me. I also will try to post weekly on this blog to keep you in the loop about what is going on in science. Please subscribe to my Remind by texting @eec738 to 81010 for Science OR @abakd to 81010 for Pre-AP Science. I look forward to getting to know your child!

3 methods of heat tranfer

Image
Radiation is the transfer of energy by electromagnetic waves. It is the transfer of energy through space, The source is mainly the sun, but can also be microwaves. Convection is the transfer of heat by the flow of a heated material. It usually occurs in gases and liquids. Conduction is the transfer of heat through contact. It usually occurs through solids.

Newton's Laws

Image
Newton's 1st Law states that an object in motion stays in motion and an object at rest stays at rest until acted on by a force. Newton's 2nd law has to do with force, acceleration, and mass. It really means that if you increase mass then acceleration will decrease (of course because it weighted down) and if you increase force, acceleration will increase. They are all related in a formula: Force=mass x acceleration. An example would be if a pitch a baseball it will go faster than if I tossed it gently because I put more force behind the pitch! Also, heavier things require more force to accelerate like the illustration below.                       Newton's 3rd law says that for every action there is an equal and opposite reaction. The best example of this is a rocket launch. The gases combust out the bottom of the rocket and in turn the rocket gets pushed up in air. Equal and opposite forces!

Vertebrates

Our new unit is on Vertebrates. We will be studying animals until the end of April. Important Info on Vertebrates All vertebrates have a backbone.There are 5 kinds of vertebrates: fish, mammals, amphibians, birds, and reptiles.  Here  is a link to more information on vertebrates. Another helpful website is  http://www.davidlnelson.md/Cazadero/FiveVertebrates.htm . Fish : cold-blooded, most have scales, breath in water (gills) Birds : warm-blooded, feathers, lay eggs Reptiles : cold-blooded, scales, lay eggs Amphibians : cold-blooded, start out living in water with gills and transition to land growing lungs (transition), lays eggs in water Mammals : warm-blooded, nurse their young, fur/hair Invertebrates are animals that do not have a backbone/spine.
