Can You Hear It?

This week we are working on light and sound waves for science. The littles are interested in knowing how things work. Some might not be as interested in all the facts as others. We liven it up to make it go a lot smoother.

In this experiment we used three different mediums (air, water, and sugar) and a coin to see if we could here sound through each one. Each child had paper and a pencil for recording their findings on.  

The supplies for our experiment. Air, water, sugar, and a coin.

To start off the experiment they each took turns with the bag of air. I filled it myself and they are used to my hot air.  At least it keeps them warm in the winter. Measured half a bag of water an d sugar. The littles wanted to eat the sugar afterwards. Ummm... No thank you. I like my sanity to stay intact and their beautiful smiles. I tapped the table for each child with the coin as they listened through the bags. 

Bag #1 Air

Connor was showing me how to blow air.

Bag #1 was our first and held only air. The bag didn't want to stay inflated. It had to be filled a few times before we finished the experiment.  Chloe, James, Connor, Jazlyn, and Sophie had fun the air pillow. 

What ever Chloe is hearing makes her smile.

Jazlyn liked hearing the sound through water. It was cold.

Bag #2 started our second round to the experiment. This was the half bag of water. Of course it was cold water. A little soothing on the ears. This one I received a few thumbs up for. 

James is thinking that is a lot of sugar.

Nap time with sweet dreams... Sophie

Bag #3 is the bag of sugar. We used natural brown cane sugar. This was the bag they were the most excited about. Any child I think would be. Each one took their turn. I am sure there might have been some sweet day dreams going on while they were conducting the experiment. 

After we were all done the children talked about what they had heard. Air was the loudest. Water closely followed right after it. The sugar was muffled to them. Between the three mediums they got to see how sound transfers through different items. Except Sophie, she heard a fox in her bags.

Hands on experiments are the best way for our littles to learn. They do well with oral questions and going through the different parts of the lessons. Each one trying to out answer the other one. Can't wait till the next experiment.
