The 5 concepts of science for last 6 weeks

Safety equipment

Gloves

Insert hand in to the glove and make sure your hands are fully covered. You use gloves to protect you hands.

We use a apron to protect our body. How to put an apron is you get the strap and put it around your neck. With the apron in the front of your body. Take the straps hanging at your side and tie them in the back or your body.

We use a fire blanket to set out small fires such as a class fire. How to use it is to unfold the fire blanket and set the fire blanket on a small fire.

Goggles

You use these to protect your eyes hen doing a science experiment. How you put them on is to pull the strap back. Then you put I over your head. Finally you secure them on your eyes.

Eye wash station

How to use is to not rub your eye, Take person to eye station, Rinse eye out for 15 minutes.

Fire Extinguisher

How to use it we call it P.A.S.S. P-Pull the pin, A-Aim at base/source, S-squeeze trigger, S-Sweep back and fourth.

Minerals

How to tell hat mineral it is mostly use Moh's hardness scale. There are other ways as well like luster. That is if it is shiny. There is also streak. That is what color it is if you scrape it on something. There is color as well. How you test color is you easily look at it and classify it into groups like purple,orange,etc.

Varibles

A variable has two parts. They are called independent and dependent variables. An independent variable does not change but a dependent variable does change.

metals,nonmetals,and metaoids

There are many ways to classify in to these categorys like Conductivity. That is if you can make a complete circuit using it. If you can then it is a metal or metaloid. There is other ways like luster if it is shiny it is luster. There is malleable. If you hit it does it shatter? If so it is not malleable. Then there is ductile. If you can make a wire out of it it is ductile. There is brittleness. If you can easily break it it is brittle. Finally there is magnetic which is tested with a magnet.

Density

You use the equation length* width* height to find the volume of a regular shaped object. For an irregular object you use a beaker and fill it a little higher than the object but not to much to where it will over flow. Then carefully set the object in the water and see how much it raises up. This is called water displacement. How you find the mass is to weigh it.
