Later on we did patterns of behavours Part 2 and I watched a video of a cat that was scratching all of the furniture and Harry the cat chews on cords.
So the owner of the cat had to call someone to help the cat.
They put electric wires on the furniture so the cat stopped scratching it.

Here is the script!!!

SCENE 1
INT - Enrich by the Science trolley
Title ‘Crazy, Cool Science’ comes across the screen. Camera pans across all 5 scientists NEAVE, NATASHA, KYLE, JACKSON, HAMISH who all introduce themselves with their names, ages and year group at school.
SCENE 2 - Dry ice facts
INT - Enrich by the front IWB
Set up at the IWB is a screen of facts. Each scientist will stand up, and point at their fact as the camer rolls. Insert voice overs of each child saying their fact.
NEAVE - Dry ice is frozen carbon dioxide. Carbon dioxide is what we breathe out. The temperature of dry ice is -78.5 degrees celsius.
NATASHA - The first person to discover dry ice was a French chemist called Charles Thilorier in 1835. He looked inside a metal container that had a large amount of liquid carbon dioxide and he watched it evapourate. As it evapourated, the temperature dropped. He then noticed in the bottom of the container a large chunk of solid dry ice.
KYLE - Doctors use dry ice to remove warts. They apply a small piece of dry ice and some pressure to the wart, which freezes and kills the wart.
JACKSON - It’s really important that you wear protective gloves and safety glasses when handeling dry ice. It is extremely cold!
HAMISH - When we get dry ice from our gas supplier, it is in a solid form, and then turns into a gas. We don’t see it turn into a liquid. This process from solid - gas is known as sublimation.
SCENE 3 - Facts about sublimation
Take photos of the normal process of ice - water - gas
Film the process of dry ice - gas. This process is known as sublimation
SCENE 4 - Bubbling Beakers
EXT - Alleyway next to mural
INT - Walkway in the middle of the classroom
Set up is a large measuring cylinders, half-full of cold water. We will add a few drops of food colouring to each.
HAMISH - Here we have a measuing cylinder, half-full with cold water and food colouring. What do you think will happen when we drop in some dry ice?
NEAVE - Drops in a few chunks of dry ice.
(Camera zooms into the shot)
JACKSON - The dry ice starts to release gas as soon as it makes contact with the water. Because the water is warmer than -78.5 degrees celcius, it is melting the dry ice. This gas is carbonating the water and will do so until all the dry ice has disappeared completely. This fog that you see, is perfectly safe to touch.
KYLE - What do you think will happen when we add some dishwash detergent?
NATASHA - Squeeze a few drops of detergent into the measuring cylinder.
HAMISH - This creates bubbles that move quickly through the carbonated water. When you pop the bubbles, you will notice the foggy effect again.
NEAVE - Why does the gas look like fog?
KYLE - Well, carbon dioxide bubbles are very cold, as they make their way to the top of the water and mix with air. As the bubbles burst, this gas mixes with any tiny droplets of water in the air to form fog. Because this fog is a mixture of water, air, and carbon dioxide, it is much heavier than the air we breathe. This causes the gas to drop low to the ground. The fog stays round for a little bit, until it warms up enough and disappears.
SCENE 5 - Crystal Bubble
EXT - Alleyway next to mural
INT - Walkway in the middle of the classroom
Set up is a large bowl of cold water, filled to almost the top. Next to it is a long piece of cloth, soaked in dishwash liquid solution.
NATASHA - Do you want to see us make a crystal bubble?
HAMISH - Drops in a few chunks of dry ice.
KYLE - Uses the cloth and runs it over the rim of the bowl to create the crystal bubble.
(Camera zooms into the shot)
(Let the bubble form until it gets quite big)
NEAVE - Pops the bubble.
SCENE 6 - Experiment: ‘Can dry ice inflate a balloon?’
EXT - Alleyway next to mural
INT - Walkway in the middle of the classroom
KYLE - Aim: Can dry ice inflate a balloon until it explodes?
The whole group huddles together as if having a team-talk
NEAVE - Hypothesis: We think the balloon will blow up, because the dry ice will release a gas. This will probably take a long time to do so the dry ice will run out before the balloon explodes.
HAMISH - Method: Take a balloon and open the neck of the balloon. Using tongs, place five pieces of dry ice inside the balloon. Tie the balloon off. Start the stopwatch.
NATASHA - Result:
JACKSON - Conclusion:
SCENE 7 - Final Scene
EXT - Alleyway next to mural
INT - Walkway in the middle of the classroom
All five scientists are lined up, with their beakers of bubbling, colouring potions.
HAMISH - We
NEAVE - Hope
JACKSON - You
NATASHA - Enjoyed
KYLE - Our
HAMISH - Exploration
NEAVE - Of
JACKSON - Dry
NATASHA - Ice
KYLE - We’re
HAMISH - Off
NEAVE - To
JACKSON - The
NATASHA - Science
KYLE - Lab
HAMISH - To

JACKSON - Some
NATASHA - More
KYLE - Potions
I am feeling very sorry for the cat that gets electrocuted for scratching the furniture. We just yell at ours. The bubble beaker sounds amazing. Have fun filming this week Neave.
