Inquiry Framework

Question Framework

Driving Question

The overarching question that guides the entire project.How can we, as food scientists, explore the changing states of matter in the kitchen to transform ingredients and create delicious dishes?

Essential Questions

Supporting questions that break down major concepts.

How do the states of matter change during cooking?
What are the properties of solids, liquids, and gases in food?
How do temperature changes affect the states of matter in food?
How does the state of matter impact the texture and taste?
What are some examples of physical and chemical changes in cooking?

Standards & Learning Goals

Learning Goals

By the end of this project, students will be able to:

Students will be able to explain how energy transfer affects the states of matter of ingredients during cooking.
Students will be able to identify and describe the characteristics of solids, liquids, and gases in food.
Students will be able to differentiate between physical and chemical changes in food as it cooks.
Students will be able to design and conduct an experiment demonstrating state change in food.

Entry Events

Events that will be used to introduce the project to students

Edible Experiments

**Hook:** Imagine you're a food scientist tasked with creating a new dessert that changes states of matter as you eat it. Present students with a dish like Baked Alaska (hot and cold at once) or Dippin' Dots (liquid nitrogen ice cream). **Core Question:** How can we use culinary techniques to manipulate and explore the states of matter of food? **Connection to Standards:** Directly addresses states of matter through observation and experimentation with food. **Engagement:** Connects to food, a familiar and exciting topic, and introduces the concept of food science. **Investigation Pathways:** 1. Explore the science behind specific dishes and their state changes. 2. Design their own dish that features a unique transformation of matter.

Portfolio Activities

These activities progressively build towards your learning goals, with each submission contributing to the student's final portfolio.

Activity 1

Water Works Wonders: A States of Matter Lab

Students will explore the properties of solids, liquids, and gases using water as an example. They will observe and document its changing states through freezing, melting, and boiling.

Steps

Here is some basic scaffolding to help students complete the activity.

1. Observe and record the characteristics of ice (solid water).

2. Melt the ice and observe the transition to liquid water, documenting the changes.

3. Boil the water and observe the transformation into steam (gaseous water), noting the changes.

4. Draw diagrams representing the particle arrangement in each state of matter and explain how energy transfer causes the changes.

Final Product

What students will submit as the final product of the activityA comprehensive lab report detailing observations, explanations of state changes, and diagrams of particle arrangement in each state.

Activity 2

Recipe Remix: States of Matter in Action

Students will select a recipe and analyze the ingredients, classifying them based on their states of matter. They will then observe how the states of matter change during the cooking process.

Steps

Here is some basic scaffolding to help students complete the activity.

1. Choose a recipe involving various ingredients in different states of matter.

2. Create a chart listing each ingredient and its initial state (solid, liquid, or gas).

3. Prepare the recipe, carefully observing and documenting any state changes in the ingredients during the cooking process.

4. Complete the chart by noting the final state of each ingredient and explaining the observed changes.

Final Product

What students will submit as the final product of the activityA detailed chart listing each ingredient's initial state of matter, its state after cooking, and an explanation of the observed changes.

Alignment

How this activity aligns with the learning objectives & standardsFocuses on classifying ingredients by their state of matter and observing state changes during cooking.

Activity 3

Culinary Transformations: Physical vs. Chemical Changes

Students will further investigate the difference between physical and chemical changes using various cooking processes as examples.

Steps

Here is some basic scaffolding to help students complete the activity.

1. Research and define physical and chemical changes in the context of cooking.

2. Identify several cooking processes (e.g., boiling, baking, frying) and classify the changes occurring as either physical or chemical.

3. Explain how these changes affect the food's properties, such as texture, taste, and appearance.

4. Compile findings into a presentation, using visuals and real-world examples to illustrate the concepts.

Final Product

What students will submit as the final product of the activityA presentation comparing and contrasting physical and chemical changes in cooking, supported by specific examples and explanations of how they impact the food's properties.

Alignment

How this activity aligns with the learning objectives & standardsReinforces the understanding of physical and chemical changes through culinary examples.

Activity 4

Culinary Alchemy: Designing State Change Dishes

Students will apply their understanding of states of matter to design and create a dish demonstrating a specific state change.

Steps

Here is some basic scaffolding to help students complete the activity.

1. Brainstorm dish ideas that involve a clear state change (e.g., melting, freezing, evaporation).

2. Develop a detailed recipe, specifying ingredients, measurements, and cooking procedures.

3. Prepare the dish, carefully observing and documenting the state change process.

4. Create a presentation showcasing the final dish, including a written explanation of the science behind the state change and a sensory evaluation (taste, texture, appearance).

Final Product

What students will submit as the final product of the activityA final dish presentation, including a written explanation of the chosen state change, the recipe, the science behind the transformation, and a sensory evaluation.

Alignment

How this activity aligns with the learning objectives & standardsCulminates in applying knowledge of states of matter and their changes to design a unique culinary creation.
