The science laboratory on my school is so cool . We have been making various experiments that made my experience about science complete . My most favorite part of the school is maybe the science lab for this is where i can test my knowledge about stuff . To satisfy my curiousness of my mind . I want to explore more and more but it is limited due to the lack of time during class times i can only use our lab once for only estimated time of once per 4 months like its soo urghh . I want to use the lab more , whats the use of it if we cannot use it . So many facilities in my school is rarely use . We paid rightly and honestly so there should be a equal right to all facilities!

EXPERIMENT #1 : THE BOUNCIN’ EGG 🍳🍳

THINGS YOU WILL NEED :

•EGGS •WATER •VINEGAR •FLASHLIGHT •BOWL

FOR THIS BIOLOGY EXPERIMENT ——

1.) Put 1 whole raw egg in a glass of water . 2.) Put another 1 whole raw egg in a glass of vinegar. 3.) The eggs are the same aren’t they ?? Now, leave them for a few hours (mainly 2-3 hours)

AFTER A FEW HOURS

4.) Look at both eggs. Do they still look the same ? The egg in the water is the same, but the egg in the vinegar has change. The shell has begun to FIZZ . The acid in the vinegar dissolves the calcium carbonate that’s in the shell . 5.) Look carefully. Does the egg in the vinegar still have its shell? Touch It !! It now feels and looks like a rubber ball doesn’t it ? 6.) Leave both eggs alone for 7 days. After that time take the egg in vinegar to a dark room and shine a flashlight at it . What do you see ? The light bounces off the egg doesn’t it ? 7.) Take the egg out of the glass of vinegar. Hold the egg a little bit over a bowl . 8.) Let the egg drop. Do you think it will splatter ? TRY IT !!!!

What Happens ???!?!! 😰😰

Your egg bounces ! Try it again getting a little higher each time . See how high you can make the egg bounce . 💪😂😁

Why does this happen?? 😳😳

- A chemical change takes place in the egg when left in the vinegar . - The vinegar ; which is an acid , reacts with the calcium carbonate of the eggshell. - The change makes the shell go soft then disappear. This is called “decalcification” .
