Hello there research agents! The agency needs your help!

Today, you must explore the effects of heating and cooling on different materials. You will be gathering evidence to determine whether or not these effects can be reversed.

When heat is applied to something, it often changes the material in one or more observable ways. The same thing is true when a substance is cooled. Some of our enemies altered some very important evidence by heating and cooling it, and you must figure out if these changes can be reversed. Are you up for the challenge?

Once you discover the solution, you will write a letter with evidence to support your claim, so we know if we can save our evidence.

Let's not delay any further! It's time to dive in and find out if the evidence can be saved!! I have linked several resources that will help you discover the answer.

Task

Our mission is to construct an argument with evidence to support whether changes caused by heating or cooling can be reversed.

Throughout this WebQuest, students will:

Explore the chemical reactions of heating and cooling and their effects on various materials.
Analyze real-life demonstrations of heating and cooling, such as cooking an egg, freezing a plant leaf, or heating paper.
Identify which changes are reversible and which changes are irreversible.
Construct an argument with evidence to support their claim. This argument should demonstrate an understanding that some changes caused by heating or cooling can be reversed and some cannot.

Process

Understanding Heating and Cooling:

You will be researching the definitions and effects of heating and cooling various materials by utilizing reliable online resources and videos to grasp the concepts and complete the mission. As you watch these videos, take notes on your graphic organizer!

Cause-and-Effect

What does it mean to heat something? What happens to an object when it is heated? What does it mean to cool something? What happens when an object is cooled? Investigate the answers to these questions and more by watching this video: https://www.kidsacademy.mobi/lesson/heating-and-cooling-21923070/ Take notes on these reactions on the back of your graphic organizer.

Diving Deeper and Exploring Real-Life Examples:

"Three, Two, Wonder" with Generation Genius to learn more about reversible and irreversible changes that occur when items are heated and cooled. Use the graphic organizer to take notes on the cause and effect of applying heat and cold as you watch the video linked below.

Evaluation

Your understanding of the changes caused by heating and cooling will be assessed based on the following criteria:

	5	3	1
Claim and Evidence	Claim stated and backed up with appropriate evidence.	Claim stated but no evidence given, or evidence is given, but there is no clear claim.	No claim or evidence is stated.
Completion and Accuracy	Letter is complete and wholly accurate.	Letter is either not complete or it is complete, but the information included is not accurate.	Letter is neither complete nor accurate.
Neatness and Clarity	Work is neat, clear, and concise with little grammatical errors.	Work is mostly neat, clear, and concise, with few grammatical errors.	Work is neither neat, clear, or concise.

The goal is to score all 5s, for a total of 15 points.

Conclusion

Congratulations, researchers! Your letter has been sent to the agency, and now they have access to the information they need to save their evidence! Plus, now you have learned all about the effects of heating and cooling. I am so proud of all of you! Continue helping others and exploring the world around you. There is so much you have yet to learn!

Standard: 2-PS1-4 Construct an argument with evidence that some changes caused by heating or cooling can be reversed and some cannot.

DCI: Chemical Reactions: Heating or cooling a substance may cause changes that can be observed. Sometimes these changes are reversible, and sometimes they are not. (LE.PS1B.a)

Examples of reversible changes could include materials such as water, butter or crayons at different temperatures.
Examples of irreversible changes could include cooking an egg, freezing a plant leaf, or heating paper.

Science & Engineering Practice: Engaging in argument from evidence: Engaging in argument from evidence in K-2 builds on prior experiences and progresses to comparing ideas and representations about the natural and designed world(s).

Construct an argument with evidence to support a claim.
