refraction

if you do flat the reflection is the opposite. Refraction is the bending of light when it passes through a medium with a different density, which causes it to change direction. This phenomenon occurs due to the variation in the speed of light in different materials. Lenses use this property to help us see objects, while objects viewed through transparent materials can appear distorted.When light passes through a medium with a different density, it changes direction, which is called refraction. This happens because the speed of light varies in different materials and causes it to bend. The extent of the bending depends on the angle of entry to the medium and the difference in density between the two materials. This is how lenses allow us to see objects and why objects look distorted when viewed through water or other transparent materials.

The eye

What are we going to be doing for the next few lessons?

Cornea: The protective outer layer

Pupil: Where light the eye. is a hole for light to pass through

Iris: Controls how much light enters. colored part

Lens: Focuses light onto the retina

retina: converts light into electrical impulses

optic nerve: carries the electrical impulses to the brain

humours: the liquid mush inside the eye that gives it it’s shape

Being Active Helps With Mental Health

Being active releases chemicals in your brain that make you feel good – boosting your self-esteem and helping you concentrate as well as sleep well and feel better. – Google

 

Exercise is a natural and effective anti-anxiety treatment. It relieves tension and stress, boosts physical and mental energy, and enhances well-being through the release of endorphins. Anything that gets you moving can help, but you’ll get a bigger benefit if you pay attention instead of zoning out. – Google

New Research on Unlimited Clean Energy?

Recently there has been an exciting breakthrough in the field of clean energy research. Scientists have been developing a new technology that could provide unlimited clean energy for the future. This technology is called nuclear fusion, and it involves using the same process that powers the sun to create a point without any harmful emissions. The research has shown promising results, and if successful, it could revolutionize how we power our homes and businesses. The potential for unlimited clean energy could also significantly reduce our dependence on fossil fuels and help us combat climate change. Exciting times are ahead in the world of clean energy, and we can only hope that this research continues to progress toward a sustainable and bright future. But this has all been discovered by trying to get energy outside of Earth, thinking outside the box, and not thinking of ways to develop the same process of energy that we already have now.

 

 

filteration experiment

key words

soluble

insoluble

filteration

aim to make a mixture then filture it

hypotysis I think the mixture will stay liquid and will be light blue

copper sulfate + sodium carbonate >

copper odium + Sodium Copper | Copper Carbonate | Sodium Sulfate |

 

Copper Sulfate (blue) + Sodium Carbonate (colourless) >

Copper Carbonate (blue, solid) + Soium Sulfate (colorless, liquid)

=

Blue colourless, solution.

when we put the potassium permanganate in the water it turned really purple then it was lighter and lighter

chemistry

matter: anything that takes up space. made of things called particles

the more space matter takes up, the states of matter

STATES OF MATTER: the particles of matter

solid

  • fixed shape
  • fixed volume
  • least energy(particles only vibrate in place)

liquid

  • fixed volume
  • no fixed shape

gas

  • no fixed shape
  • no fixed volume
  • has the most energy(particles move more)

other facts

  • to change states of matter we need to add or remove energy
  • to add energy we expose the particles to heat
  • to remove energy we cool the particles down

melting

SOLID->LIQUID->GAS

freezing

SOLID<-LIQUID<-GAS

Evaporation: Change in state from liquid to gas. Energy is needed for change.

Freezing: Change in state from liquid to solid. Energy is removed for this change.

Melting: Change in state from solid to liquid. Energy is needed for change.

Condensation: Change in state from gas to liquid. Energy is removed from the particles for the change.

What was the fastest why

we used the solute (sugar) and the solvent (water) and stirred them to make the solution and hot water to make the process faster

when we heat
