Can You Make it Move?

Today the Pine kids were asked the question "can you make it move?"

They tried a little experiment. What could they make move just using their breath?

B picked up a straw and started blowing through the narrow hole. 

"It's not moving! It's too hard to move."

B tried blowing harder. No luck. 

B picked up a cork instead. He first set it up so that when he blew through the straw the cork rolled across the table. His face lit up. He placed the cork back down on the table, but this time the flat end was towards the straw opening. He blew hard. 

"It's not moving anymore!"

He looked at the cork and then looked into the container full of other materials. He quickly wrapped the cork up in some paper and tried blowing it again. It worked! B then got another cork to try again. 

L wanted to give it a try. She picked up the pinwheel and started spinning it with her finger. She looked around and saw the others were trying to blow paper and feathers across the table. L then pursed her lips and started blowing. 

The pinwheel started spinning slowly. She giggled and blew harder. The pinwheel started spinning faster and faster. E asked to have a turn. 

He watched L blow on the pinwheel and imitated her same play. He,too, started to blow harder as the wheel spun faster and faster. 

"It's going fast! It's moving!"

E put the pinwheel on the table and started to blow, but nothing happened. E tried again and blew a little harder. The pedals of the pinwheel started shaking along the table. 

"Why it not working?"

E was confused. Why was the wheel working when he was holding it, but not when he put it on the table?

E gave up on the pinwheel and grabbed his straw and a cork. He started experimenting with making the cork roll using his breath. In the video below you can see how E figures out that the cork rolls when he blows through the straw. Towards the end of the video E starts clearing the table to make more room for him to try other materials  

At the end of the day we talked about the different materials that were easier to blow across the table. 

"The paper was the easiest!"

"The feathers were easy too."
"The blocks were hard because they are too strong."

"Yeah the blocks are too heavy. We can't blow through a straw to make it move."

"I could blow the pinwheel too!"

Our conversation ended with deciding what was easier to make move on the table using our breath. We had a lot of questions at the end of the day that we are hoping to explore over the next few days. 

What is easier to move?

What's harder to move?

Can the wind move heavy things?
