My Learning at home

I am in Grade 8 – Science

 

Cells and Systems

Osmosis and Diffusion

Diffusion and Osmosis
Diffusion and osmosis are explained in this presentatio, which also adds to the vocabulary of terms that are useful in describing scientific concepts involving the actions of molecules and atoms under various conditions. (18:58)

Composition of Blood

What is Blood?
Watch this video and you will quickly learn what the major components of blood are and what they do for the body. (2:23)

Optics

Additive Colour Theory and Light

Optics 4 – Additive Colour Theory of Light
What happens when you blend different coloured lights together? You may be surprised to learn what actually makes white light. (4:10)

Laws of Reflection and Refraction

Reflection of Light – Elementary Science
What is it that you actually see when you look at a mirror or other reflective surface? (0:49)

Laws of Reflection and Refraction

Reflection and Refraction of Light
When light bounces off a shiny surface, we call it reflection. When it appears to change shape or bend, we call it refraction. Refraction depends on how different types of media affect light. (6:17)

Fluids

Pressure, Volume and Temperature

Gas Volume and Pressure
Knowing that gases are particles that try to keep away from each other, hereís what we might expect if we increase the amount of gas we keep in an enclosed space or raise the temperature of that gas. (1:04)

Water Systems

Heat Capacity of Water

Fire Water Balloon Ė Cool Science Experiment
Here is a science experiment with results you may not expect. Itís an excellent first step in discovering some extremely useful things about how water reacts to heat. (3:06)

Coriolis Effect on Oceans

Bill Nye the Science Guy on Ocean Currents
Itís common knowledge that ocean water is salty. Bill Nye shows us how sunshine changes the concentration of salt, resulting in thermohaline ocean currents that affect the entire Earth.
