Here's another example of a built-in foldable. 

Under each flap, you can have students write the definition, or draw the phase change representations. Then, next to the word, on the next page, you can have them do something else. Below is an example of how students can then make more meaning by drawing or writing to describe an everyday example.

This is a great foldable to help organize thoughts on structure and function.
First you fold the top and bottom corners in to make a sideways house. Then, label the side of the page with the adaptation (leaves). You may want to flip the structure and function locations. 

Then, underneath you can either provide the structure, and the students have to come up with the function, or vice-a-verse. 

The above picture is obviously a spanish example, but think of the worksheet below as a grid filled with pictures of plant and animal structures. Students have to write the function of the structures in sticky notes and place them on top of the picture. 

This is similar to a 4 tab flip book, it may be more difficult to show a sequence of events, but it fits into a science journal nicer. If you are super creative, you can even make the front 4 panels one huge picture with each quadrant of the picture represent a vocab word. 

This book is good for organizing information occurring in 4. You can make the tabs all the same size, or you can customize the flaps to fit the information. Just simply fold the paper hot dog style and cut the top flap into as many tabs as you need. 

This book is also good for showing a short sequence. Ex: Life cycles. 

Students can also use this to collect data for an experiment that may last several days. One one flap they draw what they see, on the flap underneath, write their observations. 

This can easily be made into a 4 tab foldable. This is great for vocabulary. Students are able to represent the information in different ways. 

In one box, have the students write the vocab word.
The one box, have the students draw a representation of the word.
In one box, have the students write the "official definition"
In one box, have the students write the definition in their own words.

If you want, you can even have students write the definition in another language, or draw non-examples. 

You can teach the students to create this foldable, or just print out templates for them to cut out. You can download a template that I created below.
