Happy Spring, everyone!  Let's welcome a fresh new leaf, the  glorious spring of 2018! 

Spring time is a good time to encourage families' involvement in their children's science learning in the classroom, at home and in the community.  Let us help our children recognize science everywhere and in doing so, we motivate them to explore, develop curiosity and ask questions.
It is fun to explore EGGS, the  symbol of birth, a new beginning!  A bird's egg is rather like a spaceship.  Inside is a living thing, a chick. which has to survive in the hostile environment outside its mother's body.  The shell of its space capsule provides protection, and inside is all the food and water that the living inhabitant requires.Observe the stages of development of a chick, from an egg until the right stage of development, when the chick breaks open the shell and struggles free into the outside world.

More fun science play for you and your child...


l.  Popcorn Dance!  It is a delightful way to observe chemical reactions between vinegar and baking soda. Observe how bubbles of carbon dioxide produced by this reaction caused the popcorn kernels to dance!

2.  Raisins can dance too!   After pouring in a clear carbonated pop drink into a big glass, let your child mix in about l0 pieces of raisins.  Over the next minutes, your child will observe the movements of the raisins in the glass.  They sank at first but after some few minutes, the raisins started rising and moving on to the carbonation.... and dance!

3.  "See inside a Shell" -  A seashell may look like a beautiful, hollow treasure, but to a certain sea creature, it was home. These sturdy shells are home to invertebrate animals with slimy, fragile bodies, such as cockles and snails. The shells protect their bodies from the elements and predators.  They have different shapes making it difficult to look inside.  With a sandpaper, you can scrape holes in shells and see how they are built.

4.  Why can you hear the ocean when holding a seashell to your ear?
Do you remember trying this as a kid... holding one of the seashells you grabbed as a souvenir up to your ear? It seems like no matter how far away from the ocean you are, you can still hold a seashell up to your ear and hear the roar of the waves rolling onto the shore.  The best shells for producing this sound are the large, spiral conch shells. The most likely explanation for the wave-like noise is ambient noise from around you.  The seashells that you are holding just slightly above your ear captures this noise, which resonates inside the shell. The size and shape of the shell has some effects on the sound you hear.  Different shells sound different because different shells accentuate different frequencies.

You don't even need the seashells to hear the noise.  You can produce the same "ocean" sound using an empty cup or by cupping your hand over your ear.  Go ahead and try it and vary the distance at which you place the cup near your ear. The level of the sound will vary depending on the angle and distance the cup is from your ear. Noise from outside the shell also can change the intensity of the sound you hear inside the shell.  You can look at the shell as a resonating chamber.  When sound from outside enters the shell, it bounces around, thus creating an audible noise. Hence, the louder the environment you are in, the louder the ocean like sound will be.
