Science project models can take up a lot of time and effort to make.
Science project model can take up a lot of time and effort to make.
Not only do they need to be creative, they also need to function in order to
explain the whole point of the scientific phenomena chosen. The science
project model can take up a lot of time along with being a little
tedious. When a child has a science project to submit, the parent starts
fretting and worrying. But you don’t have to do it anymore! With these easy yet
working science project models, you can explain scientific
phenomena easily.
- Colour changing milk model
This science project model teaches
the kids to understand a lot about molecules at work.
All you need-
- Plate
- Milk
- Dish
washing soap
- Food
colouring in variant colours- example, red, green, yellow and blue
- Cotton
swabs
To make this science project
model work, you can begin by-
- Pour
down the milk on the dinner plate until it reaches the depth of atleast
1/4th inch. Let the milk settle down and be devoid of any waves or such.
- Now
gently drop a single drop of food colouring to the milk. All four variety
of food colouring can be dropped slowly. But make sure that you drop them
close enough at the centre of the plate full of milk.
- Without
disturbing anything, grab a cotton swab and gently touch it on the middle
of the plate where the food colouring is dropped. Do not stir or disturb
the milk. Simply gently touch it. Observe what happens and note down the
specifications.
- Now,
take another end of the cotton swab and dip it inside the dish washing
soap. Now dip the soapy part of the cotton swab in the middle of the milk
and hold it in the position for 15 to 20 seconds. Now again observe what
happens.
- The
colours will burst and the milk will change the colour.
- You
can even place the cotton swab with soap on different parts of the milk,
but the colours will continue to burst. Even when the cotton swab is
removed, the colours continue moving.
- Periscope
This science project model acts
like a periscope and shows how it can be used in pool or like a corner.
All you need-
- Circular
shaped mirrors- 2
- 2
PVC pipes that are of 12 inches section. The diameter of one is taken
larger than other one in order to easily slide up and down.
- Two
elbow joints are taken for fitting the pipes
- Adhesive
putty to bind
To make this science project
model work, you can begin by-
- At
an angle of 450, the back of the mirrors should be placed and stuck at
the inner surface of the PVC pipes. The adhesive putty is used for doing
this.
- Now
use the adhesive again to attach the inner surfaces of the pipe. The size
should be same.
- The
larger pipe should slide over the smaller one.
- Use
patterns and colours to decorate the pipes.
- Use
the mirrors for gazing outside. The length of the periscope can be
extended easily by doing this. The larger part of the pipe is used for
sliding up and down for extending the length of the periscope. Explore
the surroundings in a never-seen-before science project model.
The periscope is made and functions accordingly.
- Newton’s colour wheel
This science project model is
used for showcasing how all the colours combine together to form white. It also
shows how all the seven colours of a rainbow emerge from one single colour-
white. This science project model works on the Newton’s theory
of colour wheel.
Isaac Newton had demonstrated how
white light is the combination of all the seven different colours that can be
seen in a rainbow. With this model, a Newton’s disk is made which consists of
all the seven colours. On rotating, the seven colours blend together and fade
into white light. Apart from colours, the same can be demonstrated by using
coloured lights.
All you need are-
- Crayons
or paint colours
- Cardboard
piece
- Wire
- Battery
- Motor
- Scissors
To make this science project
model work, you can begin by-
- Start
by cutting the cardboard in a circle, forming a disk.
- Now
take a ruler and divide the circle in seven equal parts.
- Take
your own choice crayon or paint colours, to paint the seven areas into
seven colours of the rainbow: VIBGYOR (i.e. violet, indigo, blue, green,
yellow, orange, red)
- Start
by connecting battery and wires to the motor. Take help or guidance of
some elder person and make a setup in such a way that the disk rotates
like a fan on switching on the motor.
- When
the disk starts rotating, you will notice how the seven colours merge
together and only white colour is seen.
- A Breathing machine
This science project model is
easy to make and is a great way of explaining how the lungs work. This model is
easy to make as long as everything is done perfectly and there is no exchange
of air.
All you need are-
- Plastic
airtight bottle
- Two
red balloons and one blue balloon (colours can be chosen accordingly)
- Masking
tapes
- Three
straws
- Adhesive
(For making things easier, make sure to use a strong adhesive. Avoid
using cheap quality.)
To make this science project
model work, you can begin by-
- Cut
down the base of the plastic bottle in a nice straight cut. Make sure
that it is evenly cut or else the bottom of the bottle won’t be able be
sealed airtight later on. Keep the bottle cap properly since we would
need it later on.
- Cut
down the three straws in equal length of 10 cm. One of the straws
represents the breathing tube or trachea that helps in connecting throat
to the lungs.
- Now
cut down the red balloons by their end. The red balloons are
representative of the lungs in human body. This model uses the two red
balloons like lungs from which air is inhaled and exhaled.
- Take
one straw and push it 2 cm inside the red balloon. Wrap it around and
deal it with a masking tape in order to make it an airtight joint. Use
second straw and repeat the procedure. These would represent the bronchi.
- Take
the third straw and cut it in the middle up to 2 cm. The cuts should be
equally made. Flip it another side and cut it like before. Then, cut it
again so that the straw is divided into four equal parts. Basically, the
third straw has two equal cuts on one end while four equal on another.
- Now
use the two partition side of the third straw and push into the two
balloon straws with it. This would ensure that the balloon straws would
be attached to ends of the two way split straw. Again, secure them with a
masking tape in order to avoid any air exchange.
- Now
take the bottle cap and cut a hole in the middle. It should be big enough
for the four equal halves of the straw to get through it. Cap the bottle
again while stretching the straw ends. Tightly seal the bottle cap with
tape in order to avoid any air leak. The model needs to be completely air
tight for working. Any air leak can cause the project to fail.
- Cut
the blue balloon right below the neck. This part would represent the
diaphragm. Now tie the end of the balloon like we do it usually. Stretch
it and cover the exposed part of the bottle with it. The end of the
bottle will be secured safely with this outstretched balloon. Like usual,
secure it with a masking tape to ensure that the bottle is air tight.
- The
working breathing model is now complete! For showcasing breathing in, you
can pull down the ‘diaphragm’ or blue balloon and for breathing out or
exhaling, you can release the blue balloon back to its initial position.
- Now
take a chart paper and cut a human like figure to mask the model.
Covering up the bottle is completely option. We are only doing this to
make the model look more authentic. You simply have to place the bottle
in such a way that the red balloons look like lung only. Inflating and
deflating the balloon is indicative of respiratory system in the body.
These extremely
simple science project models are sure to grab eyeballs and make
your project shine amongst the peers. These don’t cost much and explain a lot.
They represent the phenomena happening within the world practically. The science
project models work for the best and can be easily made at home. So,
the next time you have to submit a working science project model,
go ahead and make one out of these.
