Students will now address the investigation question, What happened to the water?, by making a special type of drawing called an annotated drawing. Scientists use annotated drawings to explain something they have not been able to directly observe. It allows them to share their best thinking and reasoning about how something happens.

Students have observed that mist sprayed on the side of the cup disappears. They have not observed exactly what happens to the water once it has disappeared, so their explanations will have to depend on their reasoning about what they think happened. They develop and share their explanation by making their own annotated drawing.

Refer students to the sheet labeled Annotated Drawings at the back of the Science Notebook. The sheet highlights the important elements of an annotated drawing.

Review the key points of an annotated drawing with them, and then put the Annotated Drawings poster in a place where all students can see it.

On the notebook page [What happens to drops of water?], students make an annotated drawing that explains what happened to the water that disappeared from the side of the plastic cup.

As students are working, circulate among them to get a sense of the range of ideas they are developing. This can help you to highlight some contrasting ideas during the discussion.
