I love my new science lab toys. There are so many science activities to do. I started off with the color lab where I make my own colors. I played over and over again. My neighbor Chloe played with me too. I spent more than 2 hours playing this and wanted to play more. I used color tablets, test tubes, pipette and measuring cup. What I learnt:
1. Primary colors are blue, yellow and red
2. Pipette is used by chemist to suction liquids
3. I can mix 2 or more colors to make a new on
4. I also learnt what a color wheel is
Today mommy and I made a cool lava lamp. Mommy wanted to make a blue lamp but I wanted a green one so we ended up making a green one!!
Me with my lava lamp!
We took an empty bottle. You can take any empty bottle. Fill it 1/4 with water and the remaining with vegetable oil. Then you can add you favorite food color. I used 10 drops of green food color. Once the food color reached the water, the water turned green. Then I put broken pieces of Alka Seltzer in and whoa there were so many green color bubbles floating up, moving around. When I put more Alka Seltzer, we got a tornado inside a bottle!
What I learnt:I learnt that oil and water dont mix because oil is thicker than water. I also learnt the color mixes only with water and not oil. I also learnt that when I add water, water goes to the bottom and oil stays on top because water is heavier than oil.
What you need:
Here is my video:
Mommy's notes: How does it work?
How do the bubbles form? The Alka-Seltzer tablet reacts with the water to make tiny bubbles of carbon dioxide gas. These bubbles attach themselves to the blobs of colored water and cause them to float to the surface. When the bubbles pop, the color blobs sink back to the bottom of the bottle.

This is very cool chemistry project I did with my mommy today and I learnt that if you mix an acid and a base you get a reaction!
We used a baking powder as base and vinegar as acid and poured into our plastic volcano! When the vinegar touches the baking soda we got a chemical reaction which was our fake lava!!
To make it fun we added some color drops to our vinegar!
You can buy the pocket volcano at www.kids4science.com and you can reuse it over and over again!
What I learnt from this project:
If you mix an acid and a base you get a chemical reaction.
What you need for this project:
Below are the ingredients we used. You can buy them from any grocery store.
Method:
Here is a video of how we did it!
Mommy Notes:What actually happens is this: the acetic acid (that's what makes vinegar sour) reacts with sodium bicarbonate (a compound that's in baking soda) to form carbonic acid. It's really a double replacement reaction. Carbonic acid is unstable, and it immediately falls apart into carbon dioxide and water (it's a decomposition reaction). The bubbles you see from the reaction come from the carbon dioxide escaping the solution that is left. Carbon dioxide is heavier than air, so, it flows almost like water when it overflows the container. It is a gas that you exhale (though in small amounts), because it is a product of the reactions that keep your body going. What's left is a dilute solution of sodium acetate in water.

Since Rehaan is too young to understand this, for now he is just learning that when you mix acid and base, you get a reaction. He made an analogy that when food enters stomach, the stomach acid works on the food and you get a reaction called burp!
Mommy came up with a very cool and fun project for me to do to see how I can make water rise up!!! I call it Plump Up the Water!!!
Such a simple project but so much fun and so much to learn! Here is the video ....
What I learnt : If I put a bigger marble, I could make the water rise up faster!!!
What you need for this project:
A cup or beaker with measurements, water and some stones or marbles. You could also try with other objects.
Earlier during the day I read a story about how a thirsty crow wanted to drink water. The thirsty crow found a little water in a vase that it could not reach, so the crow put pebbles into the vase and water slowly rised up to the top and the crow could drink it. I loved this story and it was fun to do what the crow did. I will post a separate post on this storybook and others that my grandparents sent from India.
Mommy's Notes: Law of buoyancy, discovered by Archimedes, which states that any object that is completely or partially submerged in a fluid at rest is acted on by an upward, or buoyant, force. The magnitude of this force is equal to the weight of the fluid displaced by the object. The volume of fluid displaced is equal to the volume of the portion of the object submerged.
