Research:

Method:

Equipment

  • Tea candle
  • 4 straws
  • 2 Bamboo sticks
  • Medium-sized bin liner
  • Bottle cap

Instructions

  1. Get your equipment ready and be safe.
  2. Glue your 4 straws together, make a cross then have two other straws on the outside.
  3. Connect the bin liner to the straw so that it’s in a position that it will inflate when filled with air.
  4. Put the bottle cap in the middle of the cross.
  5. Light a fire with the tea candle and give it a little bit of support by holding it until you’re sure it can float on its own.
  6. Once you’re happy with the result let the fire burn out then water down the cap.

eye dissection

Aim:

I want to find out how to dissect an eye to see how the eye works.

Research:

 

Method:

Equipment

  • Safety Glasses
  • Gloves
  • Scissor
  • Scalpel
  • Tray
  • Eye

Instructions

  1. Get your equipment ready and be safe at all times.
  2. Make an incision between the cornea and the outside stuff. Cut out the cornea out and flip it over
  3. Remove the lens of the eye.
  4. Remove the jelly aka the aqueous humour.
  5. Cut around the sclera (the white in the eye)
  6. Remove the retina
  7. Look for the optic nerve and the blind spot

 

Results:

(no photos)

Once we removed the outer tissue of the eye we got a clearer view of the outside of the eye and could see the optic nerve. We then made an incision in the corner, flipped it over then removed the lens from the eye. The lens looks kind of cool, it’s like a bright greenish, blueish matter shrouded deep within the eye. Once we removed it the eye was pretty empty, then we didn’t have time to finish so we put the eyes in newspaper.

Catapult war

Aim:

I want to find out how to make a catapult.

Research:

Method:

Equipment

  • Rubber bands
  • popsicles
  • solid ammo (pebbles, fruit bursts etc)

 

Instructions:

  1. Copy a youtube tutorial, maybe one of the ones I linked idk
  2. Grab a good amount of solid ammo to use
  3. Have fun

Results:
Bryce messed up the catapult so I just spent the duration of the catapult war helping the boys team out and grabbing ammo for us.

Nuclear Energy – grape plasma

Aim:

I want to find out how to make grape plasma.

Research:

Method:

Equipment

  • Microwave
  • Any type of grapes
  • Glass cup
  • Safety glasses

Instructions

  1. Get all your equipment ready and be safe. Do not put metal in the microwave.
  2. Put on your safety glasses
  3. Cut the grape from top to bottom but not all the way. Leave a small strip of grape skin on the bottom.
  4. Put the grape in the microwave and put the glass cup over it.
  5. Set the microwave to high and turn it on.

Results:

(no photos)

The grape died. The end.

Discussion:

Explain what happened in the microwave. Use words like plasma, radiation

Once the grapes were put in the microwave, the grapes begun to melt down into the bottom and the top skin dissipated. It began to fold down and then started glowing due to the plasma taking effect. After around 10 seconds of a literal light show it stopped glowing and we took it out of the microwave. The grape had completely folded down and the stuff on the inside had completely melted into a small puddle. The skin of the grape stood pretty well but was very hot to the touch.

Coloured Fire

Aim:

I want to investigate what is chemical energy, by making coloured fire.

Research:

Method:

Equipment

  • Safety glasses
  • Heating equipment such as a bunsen burner or a lighter
  • Wire loop
  • A small beaker of nitric acid
  • Some different types of salts

Instructions

  1. Get your equipment ready and make sure to be safe
  2. Set up the bunsen burner
  3. Clean the wire loop in the acid
  4. Dip the wire loop into the salt of your choice
  5. Put the salty wire into the blue flame of the bunsen burner
  6. Observe the flame change colours
  7. Repeat instructions 3 to 6

Making a terrarium

Aim:

I want to build a terrarium.

Research:

Method:

Equipment

  • jar
  • water
  • can (optional)
  • soda bottle (optional)
  • rocks and plants
  • soil
  • moss

(by the way I’d highly advise to do this at home)

Instructions

  1. get your equipment ready
  2. put rocks/pebbles in the jar so they’re at the bottom
  3. put some soil in the jar but not too much to where it takes up the whole jar
  4. add moss into the jar
  5. if you want to do a quick terrarium build, add already grown plants to the jar

Ecology and Living Things

All living things do seven life processes…

M – movement – living things need to move their bits

R – respiration – producing energy by breathing and eating

S – sense(itivity) – detecting your surroundings like heat and light

G – grow – getting larger by adding some more cells

R – reproduce – making a clone of yourself

E – excrete – getting rid of waste products like carbon dioxide and urea (no, not s**t)

N – nutrition – absorbing chemicals into cells

 

is water alive?

to be alive, you need to do the seven life processes, aka mrsgren.

Water can and does move, but it requires help from wind and weather.

Water does not reproduce, and it does not make water children.

therefore water is not alive.

is fire alive? 

fire moves by itself.

fire does respire to make energy.

fire is sensitive to water and water retardant foam.

fire does grow.

fire does not reproduce.

fire excretes smoke and gas.

fire does get nutrition through things like people, clothes, heat, oxygen and fuel.

Chosen habitat: Canterbury Plains

Review of Canterbury Plains by Train | Christchurch, New Zealand - AFAR

The temperature of The Canterbury Plains is around 30 degrees in summer and 15 degrees in winter.

Germinating seeds

Aim:

I want to find out how to successfully germinate seeds.

Research:

Method:

Equipment

  • plastic cup
  • cotton wool
  • paper towel
  • soil
  • bean seeds
  • water

Instructions

  1. be sure to hydrate the seeds overnight
  2. get your equipment ready
  3. write your name on the cup
  4. put the cotton in the cup
  5. wet the cotton with some water. make sure you don’t add too much or too little water
  6. put a seed on top of the cotton
  7. leave the plastic cup by the window
  8. water the plant every time you come into science.

Results

put some photos of your experiment here

Conclusion:

The germination went fairly well from the moment we put the seeds in the beaker to present day. They grew to a decent size within a few days.

Discussion:

Write a paragraph of the science behind growing seeds

what does a seed need to grow?

Oxygen to respirate, water to hydrate and sun.

how does a seed germinate?

It thrives on its surroundings and atmosphere to germinate.

what comes out of the seed?

a plant.
