Science
In materials that are conductors, does the charge move easily or with reduced movement?
Easily
What is the internationally recognised poverty line amount?
US$1.90 per day
What is the line on a graph that show the most common answers?
Trend line
Where do you find protons and neutrons?
Tightly packed in the nucleus
What is the project year 10 material design students are currently doing?
reJEANeration
How do positive and negative charges react to each other?
They attract to each other (opposites attract)
How many out of nine households in New Zealand live in poverty?
1 out of 9
What is the first step in a statistics problem when you get a set of numbers?
Put the numbers in numerical order
If an object gains electrons, does it become positively or negatively charged?
Negatively
What subjects will be in the Year 10 exams
Maths, English, Science, Social Studies, Languages
If a positively charged rod goes close (not touching) to a negatively charged ball, what happened to the electrons?
The electrons will all move to the side closest to the rod.
What is Capital Gains Tax?
Tax on the profit made from selling an asset that has increased in value since it was purchased.
How do you find the median?
It is the middle number in a set of numerically arranged numbers.
In an insulator, do the electrons move freely or get stuck in one place?
Stuck in one place.
Which case study notes do you need to ensure are up to date for the exams
Guatemala case study
If an object loses electrons, does it become positively or negatively charged?
Positively
New Zealand is currently in an economic recession. What does that mean?
It means our economy is struggling, sales are slowing, debt is increasing, our GDP is down, unemployment is rising (5.3%).
What is the lower quartile?
It is the median number between the lowest value of a set of numerically ordered numbers and the overall median of the set of numbers.
What is static electricity?
Static electricity is the buildup of an electrical charge on the surface of a material, caused by an imbalance between positive and negative charges. It occurs when electrons transfer between objects (usually through friction) leaving one object with an excess of electrons (negative charge) and the other with a shortage (positive charge).
When punctuating in narrative writing, if using a ? or ! does the attribution start with a captial letter or lower case?
lower case
Explain how a negatively charged rod can attract neutral paper or water
The paper/water is neutral. Rod will be -ve and will attract the water or paper. The negatively charged rod will repel the electrons in the paper or water, leaving the positive protons to be attracted towards the rod. Neutral objects can still be attracted by charge seperation.
Name 3 things that could be done to reduce the wealth gap in NZ
Better funding for low income schools, Capital Gains Tax, lowering taxes for low earners, building more affordable public homes, Setting clearer rules on rent increases, Raising the Minimum Wage / Living Wage, financial literacy in schools
How do we find the interquartile range?
It is the difference between the upper quartile and lower quartile values.
Why does lightning occur?
Lighter, positively charged ice crystals float up to the top of the cloud. Heavier, negatively charged hail and water droplets sink to the bottom. This leaves the cloud with a positive top and a negative bottom. The ground gets attracted: Because opposite charges attract, the heavy negative charge at the cloud base repels negative charges on the ground below, leaving the ground surface (including trees, buildings, and hills) positively charged. The spark connects: Air is normally an insulator (stops electricity flowing). However, once the difference in charge becomes too great, the electricity rips through the air to connect the negative and positive zones.
What are 3 reasons why we need food?
fuel for energy, growth and repair of tissues, to help fight disease and keep our body healthy.
