Hello students and Parents!!! Make sure to check emails daily and please email any questions or concerns you may have. My contact information is above. I look forward to a great, fun year!
This week we will be taking our science benchmark Monday and Tuesday as well as continue our Medical Mystery. We will collect more evidence about what is wrong with Mkenna! As we gather data, we will look at what makes life and the inner workings of a cell. Next week will be Thanksgiving break so please get any missing assignments turned in. Students if you have been out, please check out the videos and key vocabulary below. Thank you! Let's have a great week!! If you have any concerns, please email me.
Cytoplasm- gel-like fluid that fills up a cell. Holds organelles in place.
Nucleus (nucleolus) - holds organized DNA. The center of the cell that controls activities of the cell. The brain of a cell.
Mitochondria- energy produces energy for the cell, the powerhouse of a cell.
Chloroplast- in plant cells organelles that convert light energy into chemical energy (photosynthesis).
Cell- the basic building blocks of life
Tissue- a group of cells that have similar structure and function
Organ- a group of tissues that works together to perform a specific job
Organ System-groups of organs that work together to do a job for the body ex: digestive system breaks down food
Organism-a living thing made up of one or more cells and able to carry on the activities of life

Previous Key Vocabulary and Videos
Atoms: Building blocks of matter-made of protons, neutrons and electrons.
Molecules: two or more atoms joined together chemically (touching)
Elemental Molecule: molecule with the same atoms(same)
Compound Molecule: molecule with different atoms (different)
Diatomic Element molecule- Elements composed of only 2 of the same atoms. (di=2)
Monoatomic Elements- elements that are stable as single atoms. Elements composed of only 1 atom (mono=1)
Ionic Bonding-is the transfer of valence electrons between atoms of a molecule. This creates a chemical bond that generates two oppositely charged atoms.
Covalent Bond- valence electrons are shared between atoms. the atoms of both elements gain full outer shells.
Density- How much matter is in an object.
Chemical Equation: a formula for writing a chemical reaction starts with reactants and end with a product
Proton: Subatomic Particle in an atom with a positive charge found in the nucleus with neutrons
Electron- Subatomic particle in an atom with a negative charge equal to the number of protons, found in electron shells
Neutron- Subatomic Particle with a neutral or no charge holds protons together
Nucleus- center of an atom contains the protons and neutrons
Elements- CAN NOT be broken down. 118 different types of atoms with certain properties
Periodic Table: Table that arranges elements by number of protons/electrons and the properties that element has
Heterogenous- mixture that looks different
Solution- a homogenous mixture that all the particles are evenly distributed
Pure Substance- Made of one type of molecule that is chemically combined(connected). CANNOT be separated physically
Examples: River, lake, coffee cup. A container without a lid that is open to the environment
Matter- anything that has mass and takes up space
Mass- the amount of matter in a substance
States of matter- Solid, Liquid, Gas
Kinetic Energy- energy in motion
Potential Energy- stored energy at rest
Solid- molecules are closely packed together and contain the least amount of energy. Has definite shape and volume. Particle vibrate in place
Liquid- fluid takes the shape of its container. Particles flow over each other. Definite volume but no fixed shape.
Gas- has no definite shape or definite volume. Has the most energy and fills the area of its container. Particles move all around

***STATES OF MATTER SIMULATION***
States of matter simulation questions:
1.What happens to a SOLID when you INCREASE the temperature?
2.What happens to a GAS when you DECREASE the temperature?
3.Based on your findings from questions 1 and 2, how would you say that temperature and states of matter are related?
4.What happens when the container becomes half of its original size? Did the temperature and pressure go up? Did they go down?
5.What happens when you lower the volume of the container all the way to the bottom? Why did some students have explosions in their systems?
6.Did solids, liquids, and gasses all act the same when the volume was lowered?
7.Which particle listed does not act like the other particles when it is cooled from a liquid to a solid?
