renewable vs non renewable electrcicity

coal:coal has lots of chemical potential energy and is burnt to release heat energy.

wind:wind turbines use kinetic energy of the wind to spin a turbine.

hydro:dams can be used to transform gravitational energy,

oil:non renewable

wind:renewable

coal:non renewable

hydro:renewable

waves:renewable

gas:Non renewable

petrol:non renewable

grass/plants:renewable

generating electrical energy

once again;generating  electrical always comes back to energy transformation.

some form of energy us captured and transformed.

usually this energy is transformed into kinetic energy energy by spinning a turbine

energy

energy is the ability to make something move against a force.

this means the ability to make something move  against a force.

energy is not a  physical thing.it is carried and passed from one object to another,

the ear

pitch is a term used to described to frequency of a sound wave.a larger frequency equals to a higher pitch.

loudness us related to amplitude.A larger amplitude means a louder sound.

the outer ear has three sections:

the pinna or auricle is the part of the ear outside of our head. The part we usually are referring to when we say ear. It helps to gather sound and vibrations so we can hear more sounds.

dissected heart

date:22nd may 2025

aim:dissect the heart.

method:-identify the left and right side of the heart.

-with the dissecting scissors,cut down the middle of the middle and open it like a book

-make sure the heart stays in the dissecting tray.

-identify the different arteries,veins,values and heart strings.

discussion:

1:the veins take blood towards the heart,arteries takes blood away from the heart.

2:the right side is less muscular,the left side is more muscular.

3:the valves are a one way gate that  make the blood only move in one place.

4:pulmonary means issues  pertaining to the lungs.

5:the septum keeps the 2 sides of the heart split apart.

6:the white stuff outside the heart is a

conclusion:yes it worked,we broke the heart strings,no I wouldn’t do anything differently.

 

classification

definition:how we group different living things together.

scientists use the genus and species of a living thing a universal name

example the binomial name for a cat us felis catus

the five kingdoms are:

1:monera

2:protist

3:fungi

4:plants

5:animals

there are moderate if organisms on earth. scientists sorted these organisms into various groups based on their features, this is called  classification.

concentration and dilution

concerntration:the number of particles in a liquid.

dilution:making a concentrated liquid weaker in strength.

we  an measure in two ways

1:how dilute something is(how weak it is)

2:how concentrated something is(how strong it is)

aim:to make a dilution series to investigate concentration.

equiment:a polassiuin permanganate,six last test tubes,tweezers,a plastic transfer pipette,a test tube rack 10 ml measuring cylinder
