# Matter

 Page 1 / 1

## I spy with my little eye…..

and then describe the thing that you see by answering the following:

How does it feel? (hard, soft, etc.)

Can one eat or drink it?

Can one play with it?

The one who guesses the answer correctly gets a point. If after five guesses your partners cannot guess what it is, you get a point.

## What is matter?

Everything you can touch is matter .

Matter has mass

Try the following (1):

Pick up your ruler. What does it feel like?

Pick up your partner. How does that feel? Which one was more difficult to pick up?

My finding is that:

## Matter occupies space

Try the following:

Take a glass of water.

Put flowers in the water. What happens to the water?

Why do you think it happened?

My finding is that:

From old newspapers cut out all the pictures on the first ten pages. The pictures should be of living and non-living matter. Make two piles of pictures, one for living matter and one for non-living matter. First list the properties of living matter before you begin cutting out.

## Assessment

LEARNING OUTCOME 1: SCIENTIFIC INVESTIGATIONS

The learner will be able to act confidently on curiosity about natural phenomena, and to investigate relationships and solve problems in scientific, technological and environmental contexts.

Assessment Standard

We know this when the learner

• plans investigations:

1.1.2 talks about personal experiences, highlighting aspects which relate to science or technology.

LEARNING OUTCOME 2: CONSTRUCTING SCIENCE KNOWLEDGE The learner will know and be able to interpret and apply scientific, technological and environmental knowledge.

Assessment Standard

We know this when the learner

categorises information: sorts objects and organisms by a visible property:

• follows instructions to sort animals in groups of those with two legs, with four legs, and with more than four legs.

## Memorandum

Try the following (1)

• Pick up your ruler. What does it feel like? Pick up your partner. Which one was more difficult to pick up?
• The ruler is lighter than the partner but both have mass.

Try the following (2)

• Take a vase containing water. Put in a bunch of flowers. What happens to the water? Why does this happen?
• The water rises in the vase. The flower and the water are both matter. Both occupy space.

PROPERTIES OF LIVING MATTER

List the properties that living matter must have before you begin cutting out.

1. Movement: It must be able to move.
2. Respiration: It must be able to breathe.
3. Procreation: It must be able to breed.
4. Ingest food: It must be able to consume food.
5. Excretion: It must be able to excrete undesirable substances such as sweat.

Introduction about quantum dots in nanotechnology
what does nano mean?
nano basically means 10^(-9). nanometer is a unit to measure length.
Bharti
do you think it's worthwhile in the long term to study the effects and possibilities of nanotechnology on viral treatment?
absolutely yes
Daniel
how to know photocatalytic properties of tio2 nanoparticles...what to do now
it is a goid question and i want to know the answer as well
Maciej
Abigail
for teaching engĺish at school how nano technology help us
Anassong
Do somebody tell me a best nano engineering book for beginners?
there is no specific books for beginners but there is book called principle of nanotechnology
NANO
what is fullerene does it is used to make bukky balls
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
Tarell
what is the Synthesis, properties,and applications of carbon nano chemistry
Mostly, they use nano carbon for electronics and for materials to be strengthened.
Virgil
is Bucky paper clear?
CYNTHIA
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
NANO
so some one know about replacing silicon atom with phosphorous in semiconductors device?
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Harper
Do you know which machine is used to that process?
s.
how to fabricate graphene ink ?
for screen printed electrodes ?
SUYASH
What is lattice structure?
of graphene you mean?
Ebrahim
or in general
Ebrahim
in general
s.
Graphene has a hexagonal structure
tahir
On having this app for quite a bit time, Haven't realised there's a chat room in it.
Cied
what is biological synthesis of nanoparticles
what's the easiest and fastest way to the synthesize AgNP?
China
Cied
types of nano material
I start with an easy one. carbon nanotubes woven into a long filament like a string
Porter
many many of nanotubes
Porter
what is the k.e before it land
Yasmin
what is the function of carbon nanotubes?
Cesar
I'm interested in nanotube
Uday
what is nanomaterials​ and their applications of sensors.
what is nano technology
what is system testing?
how did you get the value of 2000N.What calculations are needed to arrive at it
