P10 - Newton’s third law

Newton's third law of motion states, "Each and every action has it's equal and opposite reaction."

This is very difficult to explain to young kids. 

Actually, Our discussion started with a different topic. She did not finish her food in school and I was little angry with that. She came to me and said, 'Mumma, if you are angry with me, I feel sad.'

I replied, 'Inu, if you become a bad girl, mumma becomes angry.'

This reminded me of Newton's third law. So, after finishing our lunch we started experimenting it.

Experiment 1: Ball Bouncing

What we need: 
        - Ball

I took a ball and asked her to just left it to the ground. She observed it going down and bounce back a little. 
Then, I asked her to push the ball to the ground with little force. This time ball bounced little more. 
We slowly increased the push force and the ball was bouncing accordingly.

It was really a fun, she tried pushing the ball with different force and observed the ball bouncing to different hights.

Experiment 2: Balloon Rocket

What we need: 
        - Paper

        - Colors

        - Double sided tape

        - Balloon

        - Disposable Straw

        - Thread or String

        - Scissors

First we made a paper rocket (drawing, colouring and cutting with Scissors). 

You can make a better rocket to repeat the experiment. This is my daughter's imagination of a rocket, and I liked it.

Next, we tied a thread with a straw threaded in it. And placed the rocket picture on one side of the straw with the help of double sided tape. 

After this, we blow up the balloon but not tied the end, then we sticked the ballon to the other side of straw with the help of double sided tape. If you repeat the experiment, be careful while doing this because the balloon air should not release while sticking it. 

Now, we released the balloon end slowly and observed the rocket going up.

We repeated this with blowing the balloon to different sizes and observed that the rocket also move according to the air in the ballon. 

It was again a fun learning activity, we both enjoyed this.

P9 - Homemade Fruit Kulfi

I know it's not the season for kulfi in Bengaluru but you can't resist one if your daughter have made it. This recipe is very simple and healthy.

Pick two or three fruits of your choice. Wash the fruits and cut them in small pieces. She selected pomegranate and papaya. Make fruit paste using a mixer. Add little salt to the pomegranate paste. Now, take a kulfi mould to set the kulfi. Fill the mould one by one with fruit pastes and place these moulds to freezer.

Once the kulfi is set, you can enjoy your testy and healthy kulfi.

P8 - Understanding Density Concept

It's been long time we have done any experiment mumma, can we do one today. This one sentence was enough to motivate me.

Today we discussed about density. Yes, it is a really tough concept to grasp. Density is how much mass in in a volume or space.

This line can't make any sense to my daughter, I need to put more efforts as she is still in Senior KG 😄.

To understand what is density, we gathered some grass and divided it in two equal parts as shown below.

Now, we took two different size bags and filled it with the grass. 

It is easy to understand that the left side bag has more grass in small area and hence more dense. This explained the density concept easily.

After this we did the experiment called: Water Oil Density. 

We pour some water in a glass and then pour some oil in the same glass.

We can observe that the oil is floating on top of the water. This is because oil has lower density than water. 

We did one more fun experiment to understand density. we took four glasses, water, sugar,  colors, straw and a spoon. We put 2 table spoon, 1 table spoon  and no sugar in glasses from left to right respectively. 

Next we added same amount of water in all three glasses and mixed the sugar.

After the sugar is dissolved completely, we added different colors in all three glasses.  

Now, we put different color solutions one by one in the last empty glass with the help of straw.

It can be seen that different color solutions are not mixed together and staking according to the density of the solution. Here, green color solution with maximum sugar has more density than other solutions and hence is in the bottom of the glass. Orange color solution with no sugar has lowest density and hence floating on the top.
