CAST Science Writer


Welcome to CAST Science Writer, the tool that supports students in writing lab and class reports. This tool is geared toward middle school and high school students.


A Report Structure

All parts of a science or lab report are broken into small steps so the author can concentrate on one part of the report at a time.

A Process for Writing

Science Writer helps you through the process of draft, revise, and edit when writing a science report.

Sentence Starters

The “Help Me Get Started” button has two functions (1) it divides the writing into smaller sections and (2) provides sentence starters when on the draft screens in the writing process. Think of it as a way to help get the writing started.


Checklists are available when you revise and edit your science report. These checklists will help you check for content and grammar errors.


This is a place in Science Writer where you may write notes, reflect, make comments or questions, or keep track of data. Click on the “Journal” button at the top of the screen to access your journal.

Text to Speech

A SpeechStream toolbar by Texthelp™ is at the top of every page. This tool has text-to-speech so you may hear any text read out loud. SpeechStream can be used to check your writing by hearing it read back to you. SpeechStream also has a dictionary and translator you may use at any time in Science Writer.

Animated Helpers

Examples and help are provided by Eko, Max, and Sam.
