WELCOME TO 5TH GRADE SCIENCE!
What's the Matter? No, what is Matter - That is our first lesson!
We will be doing experiments, but we will need supplies. I will email you our needs when we get ready to do an experiment.
Homework - Look over notes and study vocab each night :)HOMEWORK

5th grade Science – Matter – Ch 1 Notes
Matter = all living and nonliving things are made of matter. Matter is anything that has mass and takes up space.
Everything is matter and matter is made up of elements so everything is elements.
Elements = are the ingredients that make up all the other substances.- Elements cannot be broken down onto other substances with ordinary physical or chemical processes.
- There are over 100 elements
- Most elements are metals
- The properties of metals are – they are good conductors of electricity and heat and they can be shaped into sheets or wires that can bend without breaking.
- Most metals are solids and have gray color. Smooth metal surfaces can reflect light.
- Other examples of metal are calcium, aluminum and mercury
- Some elements are non-metals
- These elements do not conduct heat or electricity
- Some are gases. One example of a gases is oxygen
- Some are solid. One example is carbon.
- Some Elements are semi-metals
- Are sometime like metals and sometimes like non-metals
- For example they may conduct electricity but only when light is shining on them
- One example is silicon
ATOMS- Atoms = smallest part of an element that still has the properties of the element.
- Atom is made of
- PROTONS
- NEUTRONS
- ELECTRONS
- The number of protons determines what element an atom will be
- Atom is made of
The idea of Atomic Theory is that everything is made of small particles.
Atomic Arrangement = the way atoms are connected affects the properties of an element- Example – when carbon atoms are connected as flat sheets = soft and black = the graphite in your pencil. When carbon atoms are connected as pyramids they form diamonds = transparent and hard
- Ex Table salt.
- Example the smallest particle of water is a water molecule.
- Changing the number, kind or position of the atoms in a molecule would result in a molecule of a different substance
- Example – if you add another oxygen to H2O it is no longer water
9/10/21
In your science copybooks - Write a paragraph about one or more of the elements from page 10 and 11 in your science book. The paragraph should include a brief description of the element as well as a description of how it is used or what it is used in.
