Below we have created a suggested order for completing these activities. This is the order we use when presenting material. We based our ordering on knowledge buildup and lab difficulty. Suggested grades are also beside each activity. Feel free to use the activities however they fit best for your class. You can use one lab or several. Let us know how you used it in your class by choosing "Share With Us". We are always looking for new ideas.

• Carbon Dioxide Introduction - All grades - Students should know what carbon dioxide is before completing the labs. Some of this information can be found on our web site. We do NOT have a full introduction available here. This is teacher created.
  
  
• Bottle Blowup - All grades - Now that students "know" what carbon dioxide is we want them to "show it to us". This is activity is great to introduce students to carbon dioxide and how to study something we can not see.
  
  
• Dancing Spaghetti - All grades - Now that students can study something they can not see, we want them to learn some of the properties of carbon dioxide. This activity deals with density.
  
  
• Speaking of Carbon Dioxide - 2nd and up - This activity demonstrates that our breath contains carbon dioxide. It also introduces the idea that carbon dioxide and water makes carbonic acid.
  
  
• Acid/Base Column - 2nd and up - This activity shows students what dry ice is, discusses the density of carbon dioxide and introduces a bit about acids and bases. The acid and base information can be omitted for younger grades. This is a cool way for students to see another state of carbon dioxide.
  
  
• Stair Steps - 2nd and up - Stair steps builds on information learned in the Acid/Base column activity. It helps us to confirm that baking soda and vinegar really make carbon dioxide. Also, it is another opportunity to see the effect of something that we can not see. It shows how the properties of carbon dioxide make it good for specific applications.
  
  
• Liquid Carbon Dioxide - 6th and up - The safety issues are greater in this activity than others. Therefore, we recommend its use with older groups. Please make sure that your students are mature enough for this activity before completing it in the classroom. This activity deals with pressure and all three states of carbon dioxide.
