Science project Reusable materials around home- Balloon / Manual water dispenser

This is a science project recently done by my elder son by using Reusable materials around home.

We saw many videos online and tried to make out rubber band race car, water fountain, bottle racing car,but none was working as there is some key points not shared in the videos we saw. So am still working on it to get a correct working procedures once I get a clarity will share those on my blog.

For this experiment we used plastic
bottles,straws,rubber band, glue, scissors, small beads,old two way sketch pen caps, balloon, medicine bottle caps washer.           ( white colour circle foam type sheet on lids). Empty used tissue box to make outer cover for dispenser.

First take a bottle and make a hole on its side and insert the straw in white Cork and later put it inside the cut hole on its sides.
Now apply glue around the holes and let it dry.

Later make a hole on bottle lid and insert another straw with a white Cork. So that it looks neat. Now our model is ready.

We need to make a balloon blower. For that we need,
                                    Pic 1

Pic 2

                                     Pic 3

Take things as in pic 1,next attach balloon to one end of sketch cap rod using rubber band, now insert a straw inside a small bead and insert it through other end of sketch rod  glue around the bead part so no air leaves. Now we can blow balloon using straw. 

 We need to place our bottle model inside tissue box and our side straw part should come out if tissue box top which is now used as sides in our model as shown in picture.

Our model looks like above. 

Using a funnel fill Bott let below holes level, now blow balloon blower n join the blower straw by holding tight to the bottle straw when we take our finger air releases and pushes the water in the bottle through the hole, we need a resuable container to be placed near the water dispenser. 

This is how he completed his project with Reusable materials around home with a neat chart presentation of his model.

Maths model presentation - competition

This is our own idea for the competition.
My younger son received 3rd prize for his presentation. This competition was conducted for grade 3,4, and 5. My son did last year when he was in grade 3.

We thought of many ideas as it should be a working model. It was my DH who suggested to make models using sri chakra as it is related to maths more.

Now how to make the model as a working model. I got an idea of making sri chakra as a jigsaw puzzle pieces. As my younger one crazy about joining puzzle pieces. We can think and plan many but kids must be ready to do. Especially my younger one will not do things if he don't like.

I bought a foam sheet and took a printouts of sri chakra in a 10 rupees A4 print sheet which has laminated top part. Normal A4 paper print we can't cut exact as we need to cut sharp for puzzle pieces. As we must not spoil srichakra outlooks.

Below are some cut pieces of our model.

Now,model ready so  next is script to present this project. Instead of just saying full script nonstop to make it real explain- ing and interesting for listening we followed below things along with our script.


** We used ice cream sticks to make
      Triangles.
** Took printout of other two forms and
     Pasted on card board.
** Things need to be arranged neatly so
     It is easy to handle by kids while
     explaining.
** Empty card board for placing puzzle
     Pieces, two other forms below empty
     Cardboard,3 ice cream sticks,9 puzzle
     Pieces.
****************************************
Topic is Nine Triangles

Namasthey,i am mithran of grade3A, today I am going to talk about nine triangles.

What is a triangle?

(Now he must join 3 icecream sticks to make triangle and tell answer)

A triangle is a closed 2 dimensional shape formed by joining 3 line segments. It has 3 lines and 3 vertices.

Now let us join 9 puzzle pieces and see what we get.

(Now he must arrange all puzzle pieces,
to save time and confusion during presentation it is better to number it from 1 to 9 in pencil, during practice my son used to arrange pieces upside down from 1 to 9 so he can save time while arranging and focus on explaining part).

We get Sri chakra or Navayoni chakra which is used for worship and meditation as per Hindu shastra.

Nava means nine. You can see nine triangles in the middle.Five downward triangles representing female God Shakthi and four upward triangles representing male God Shiva.

5 interlocking triangles lead to creation of 43 small triangles with a center point Bindu.

You can see two circles with eight and 16 flower petals representing a lotus.It is framed by broken squares, representing a temple with four doors open.

Since Sri chakra is based on triangles it has three forms.

(Now he must put the top plane form other side and show below form, similarly next one)

First form is plane form
Second form is pyramid form called meru.
Third form is spherical form called as kurma.

You can see pyramid form in the kandasram temple located in camp road.

Thank you.

All script inside brackets ( ) are action parts along the oral script.

Hope this post will be helpful to all. Share your feedbacks about this.

Chart models by younger son

This a chart model for science,- my plate

This a model he did for his dream school

Tamil chart preparation by a story

This chart model done by my younger son mithran for outside school competition.

The entire picture illustrations drawn by him.

I really wondered for his great presentation.

This is a story about how srinivasa nayaka becomes great "Purandaradasa"

Show and tell for kids

This is a simple show and tell topic as Aladdin done by elder son.

Good Morning Friends,
My name is Sukarman I am from class 4b.

I am going to act like Aladdin.

Hi friends, I am Aladdin,this is my magic lamp....I love magic lamp because it grants all my wishes....

Hmmm....(thinking gesture), what can I wish for ......
1) A cool breeze to touch my cheeks... Noooo

2) A bag full of gold and diamonds nooooo...

3) yeah(idea got it gesture) A good health through the year and also to be strong and happy.

You get things, you wish for if you have lamp like this. Thank you.

The above is a simple show n tell we prepared in a day time this is non competitive one, for presenting in class. My son took a Aladdin lamp (we made  our own model of lamp) for showing.

This is the model we made, I have attached a metal bangle by bending it to make the above shape, and attached to the lamp using a metal string.

Voice modulation in above script plus some extra add on creative lines would be good. Just shared what we did.
