During instruction, check understanding of key concepts like properties of solids, liquids, and gases, or whether a given change is physical or chemical. 

Immediate feedback from the polling tool and teacher observation of real-time data. Review and discuss the answers/annotations with the class.

Purpose: Assess students' ability to differentiate between physical and chemical changes after the lesson.

Format: A quiz in Google Forms/Formative, incorporating the provided questions:

Question 1: Identify three observable properties that can be used to classify a substance as a solid, liquid, or gas. (Short Answer)

Question 2: Describe three specific changes in properties (such as flammability, color, odor, or texture) that you would observe as wood burns. (Short Answer)

Question 3: Explain why the observation of a cloudy mixture when two clear liquids are combined is not sufficient evidence to conclude that a chemical reaction has definitely occurred. What further evidence would be needed to support the conclusion that a chemical reaction took place? (Short Answer)

Question 4: Analyze the following experimental data, and for each scenario, justify whether or not a chemical reaction occurred based on the properties observed. Then, identify one limitation in the data that could affect the certainty of your conclusion:

Scenario 1: Two clear liquids are mixed, and the resulting solution becomes bright orange and produces a gas.

Scenario 2: A white solid is added to a clear liquid and dissolves completely. There is no change in temperature or color observed.

Scenario 3: A shiny metal is heated, becomes dull and gray, and its mass increases. (Short Answer/Multiple Choice if needed)

Automated feedback: For multiple-choice components.

Teacher-provided feedback: On the short answer/open-ended questions, focusing on the accuracy of the students' justifications and explanations and giving suggestions for improvement.

Class discussion: Review the answers as a class, focusing on common misconceptions and providing additional explanation.

Flexible Response Formats: Offer a variety of response formats (typing, drawing, audio) in tools like Formative.

Text-to-Speech and Speech-to-Text: Ensure that students can use text-to-speech and speech-to-text tools to access assessment content and respond to questions.

Chunking and Scaffolding: Break down complex questions into smaller parts and provide scaffolds to help students understand the concepts and answer correctly. 

Automated Feedback: Utilize automated feedback on multiple-choice or self-checking activities.

Real-time Monitoring: Use a platform like Formative to monitor student progress in real-time and intervene if necessary.

Efficient Grading Tools: Utilize built-in grading features. 

Prioritize Key Concepts: Focus feedback on the most crucial concepts and skills to manage time effectively.
