seed bank: BTN week 1

In this video it explains about seeds in a vault in the Antarctic and this video explains more.

The vault, known as The Doomsday Vault,  holds 863 000 seeds which include wheat seeds, potato seeds, and almost 150 000 types of rice. The seeds are in cold temperatures that can freeze them and grow centuries later. Storing seeds is becoming popular right around the world ,seed banks have been working together to collect and to store as many plant species as possible.

Something I learnt was that seed banks hold hundreds of thousands of seeds to plant and that it will help for the future. Also I have learnt is that the crop seeds come from nearly every corner of the globe like India, Japan, and so on.

A question I have is, why do they put the vault in Antarctica why not somewhere else where it can be cold?

 

Unit Goals: Extreme Weather

As a result of this unit, I will:

 

Unit Learning Goal 1: Science

I will . . . Understand key extreme weather terms, including:

List words here:

Extinct volcano, lithosphere, Asthenosphere, Ridge path, erosion, terraces, Geology, seismograph, Volcanology, Seismology, Limnology, Dormant volcano, tensional  stress,  Crust, Mantle, Convergent plate boundary, Ridge path.

Unit Learning Goal 2: Science

I will . . . understand scientific understandings, discoveries and inventions are used to solve problems that directly affect peoples’ lives.

Unit Learning Goal 3: Science

I will . . . understand scientific knowledge is used to inform personal and community decisions.

Unit Learning Goal 4: Science

I will . . . understand sudden geological changes or extreme weather conditions can affect Earth’s surface.

Unit Learning Goal 5: Reading and viewing

I will . . . Understand how texts vary in purpose, structure and topic as well as the degree of formality.

Unit Learning Goal 6: Writing

I will . . . Reread and edit students own and others’ work using agreed criteria for text structures and language

Features.

Personal Learning Goals: During this unit, I will .

A goal I have during this unit is public speaking and listening because I’m not really good at that and that’s something I want to work on.

science project reflection

You are doing this experiment to see if gas has a mass. Our science unit is to
see what are the differences between physical and chemical
changes.With the standard connection of: observing that gases have
mass and take up space, demonstrated by using balloons or bubbles.

Aim: To observe if gas has a mass using a kettle and a balloon.

Hypothesis/prediction: I predict that the balloon will expand because of all
the gas coming out of the kettle will rise and fill the balloon
up with the air.

DOES GAS HAVE A MASS  (click here for materials and method)

Observations: Nothing much happened. The balloon didn’t even bob up, it just
stayed on it’s side.

Explanation: We thought that the balloon didn’t blow up as much as it should
have because the water had probably cooled down by the
time we got the balloon on the flask.

Discussion: Balloons can burn so be careful if you try to put them on the
spout of the kettle or on a Bunsen burner. Since balloons can be
made of rubber, latex, polychloroprene, or a nylon fabric they
stretch well.

Conclusion: If we used vinegar or salt water instead of fresh water what would
happen then? A future experiment is that you could have is
adding more heat.

Glossary

Expand- to blow up or take up a greater space.

Latex- a milky fluid found in many plants.

Polychloroprene-  polychloroprene is in a family of rubbers.

 

100wc week 1: Sunshine, Ice, Frightened, Purple, Flew

“I have the sunshine,Ice, FrightenedPurpleFlew. What is that.” Said Joe.

“It’s just a normal flu, but with a different name.” said the doctor. The boy was in bed for 1 month and was bored. All he did was watch TV.  He waited until he was feeling better but while he was waiting he turned to ice and then purple .After a while he was feeling better and wanted to go outside but when he went outside he turned purple and felt sick again.  After 1 more month he went to the doctor and and he said he could go outside and do stuff a normal kid would do.
