The Franklin Institute’s Traveling Scien

Slide 1: 

The Franklin Institute’s Traveling Science Show By- 16 Star

Introduction : 

Introduction We got to see a wonderful show yet again. This person John did the show. It was a show about matter. He brought in liquid nitrogen. He did experiments and told us what the differences are between the types of matter. Also, he told us what would happen if would we touched liquid nitrogen without the special gloves.

Forms Of Matter : 

Forms Of Matter One form of matter is liquid. A second form of matter is gas. The third form of matter is a solid.

How can somebody change a liquid into a solid another? : 

How can somebody change a liquid into a solid another? The way somebody can change liquid into a solid is by freezing the liquid. By doing that the molecules in the liquid freeze so that it turns into a solid.

How can somebody change a solid into a liquid? : 

How can somebody change a solid into a liquid? The way someone can change a solid into a liquid is by melting the solid. Doing that the frozen molecules will melt so when a solid melts it turns into a liquid.

How can someone turn a liquid into a gas? : 

How can someone turn a liquid into a gas? The way somebody can turn a liquid to a gas is by boiling the water. When you are doing this you are evaporating the molecules in the liquid.

The Biometalic Strip : 

The Biometalic Strip The meaning on bio is 2 and metalic means metal and when you combine the words to gather it makes biometalic. Then John put it into the liquid nitrogen. When he took it out the strip was curved. It was curved because the two different types of metal were smaller than each other. So that is why is was curved. The way John got it to get straight is by rubbing his hands on the curved strip.

Ball through the Circle : 

Ball through the Circle The ball was metal and the hole had metal around it. First the ball did not fit in the hole. So then John put the ball in the liquid nitrogen. After he took the ball out, and the ball fit into the hole. The ball fit the hole the second time because the liquid nitrogen shrunk the ball.

Conclusion : 

Conclusion I hope you enjoyed the presentation. And I hope you learned about matter in the presentation.

Slide 10: 

Instructions Ball through the Circle - How did John get the ball to fit into the circle? Why did this work? 3. Balloon in Liquid Nitrogen - What happened to the balloon in the liquid nitrogen? Why? What happened when John breathed on the balloon? Why? 4. Pringles Container/Cork Bottle - Why wouldn't the lid stay on the bottles once liquid nitrogen was poured in? 5. Sponge ball against the Wall - What happened to the ball after it was put into liquid nitrogen? Why? Be sure to explain the science behind the experiments. Vocabulary: solid, liquid, gas, matter, molecules, expanding and shrinking, scientific observation, hypothesis
