Achievement standard 90954: Astronomical cycles

The asessment task for AS 90954, Astronomy Research

You need to have gathered all the resource material you require to write this project up and bring it to school day 1 term 4………….or……………

you will fail miserably and be very depressed. The four credits for this standard are the easiest science credits you will get.

How do I tackle this?

You have to describe at least two cycles from the list and link them to the effects that they have. For excellence you need to have images, data, and diagrams to show how different astronomical cycles can have more than one effect on Earth. Accompanying paragraphs explain how the different cycles and effects are linked and can influence one another.

What cycles might I chose?

There are basically two types of cycle to write about:

  1. Cycles linked to the rotation of the earth on its axis, its tilt and orbit around the sun and effects
  2. Cycles linked to the moon and effects.

We have concentrated on 1 in class. The effects you could chose to explain include:

 

  1. Day and night
  2. Seasons
  3. Changes of temperature during the day and night
  4. Changes of temperature with the changes in season at the North and South poles, latitude of New Zealand, Tropics of Cancer and Capricorn, and the Equator.
  5. Formation and the direction of winds in the Southern hemisphere
  6. Direction of surface ocean current flows in the Pacific Ocean

The first four effects are the ones we concentrated on in class.

A useful video to help with the earth’s orbit around the sun, seasons, tropics of cancer and capricorn. The effect of the tilt  of the earth’s axis in the plane of rotation around is well covered.

Fying objects the NZTA and Newton’s first law

Flying Objects (The title of an NZTA road safety video)

Information from the NZ transport agency website.

“Last year, 633 people were killed or seriously injured on New Zealand roads because they were travelling at a speed too fast for the conditions. Many people habitually speed on the open road and around urban streets. But they still consider themselves to be driving within a safe limit. They don’t realise that mistakes we all make in our driving have far more serious consequences as our speed increases.

Vehicles are much safer than they used to be. Our roads are also continually upgraded and changed to make them safer for drivers. But while improvements are constant in these areas, there’s one weak link that will never be upgraded – the human body.

Over the years average speeds have dropped and people are aware that excessive speed can cause injury in a crash. But with this campaign we aim to get people to truly understand the vulnerability of their own body in a crash.

It’s indisputable that there are limits to what a body can sustain from crash forces before it is seriously injured or damaged. Even driving just a little over the speed limit significantly increases the impact on our bodies in a crash, resulting in a much greater chance of serious injury or death.”
