1. Planning and Carrying Out Investigations—The students will investigate the concepts of properties by experimenting with mentos and soda.

2. Analyzing and Interpreting Data- The students will compare and contrast the data they received when testing each soda, recording the reaction, and analyzing the data to see which soda has the highest reaction.

3. Asking Questions and Defining Problems- The students will hypothesize on which soda they believe will have the highest reaction and what will happen when the mentos are dropped inside each soda.

1. PS2.A: Forces and Motion:

- This DCI focuses on the effects of forces on the motion of objects. While not the main focus of the activity, students may observe the physical forces involved in the eruption of soda caused by the release of carbon dioxide gas.

2. PS1.A: Structure and Properties of Matter:

- This DCI deals with the composition and properties of matter. The activity involves testing different sodas to observe their reactions to Mentos candies, essentially exploring the properties of these materials and how they interact.

3. PS4.B: Electromagnetic Radiation:

- This DCI focuses on electromagnetic waves and their properties. While not directly related to the activity, it's a part of the broader physical science curriculum.

The safety concerns that I need to consider are:

Eating/ drinking the Mentos and soda

Forgetting to wear the safety goggles and or the poncho

Not clearing off their desk and their belongings getting ruined.

1. Solid:

- Definition: A state of matter characterized by particles that are closely packed together in a fixed arrangement. Solids have a definite shape and volume.

- Example: Ice is a solid form of water. It has a fixed shape and volume and maintains its structure until external forces act upon it.

2. Liquid:

- Definition: A state of matter characterized by particles that are close together but can move past one another. Liquids have a definite volume but take the shape of their container.

- Example: Water is a common example of a liquid. It flows and fills the shape of its container but maintains a constant volume.

3. Gas:

- Definition: A state of matter characterized by particles that are widely spaced and move freely. Gases have neither a definite shape nor a definite volume, as they expand to fill the space available to them.

- Example: Oxygen gas is a component of the air we breathe. It fills the space of its container and expands to fill any available volume.

For Special Needs Children:

Have the physical forms so they can touch and see them up close.

1. Reactant: This term refers to the substances that undergo a chemical change during a reaction. In this experiment, the reactants are the Mentos candies and the soda.

2. Product: The products of a chemical reaction are the substances that are formed as a result of the reaction. In this case, the products include carbon dioxide gas bubbles and possibly some dissolved materials from the candies.

3. Catalyst: A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process. While the Mentos candies act as a catalyst for the rapid release of carbon dioxide gas in the soda, they are not permanently altered by the reaction.

4. Exothermic reaction: This type of reaction releases heat energy to the surroundings. The reaction between the Mentos and soda is exothermic, as it produces a rapid burst of gas and may also generate some heat.

# data[].attributes.body
1. Observation: Students will observe the reaction that occurs when Mentos are dropped into different sodas.

2. Hypothesis: Before experimenting, students will develop hypotheses about which soda will have the largest reaction.

3. Experimentation: Students will engage in hands-on experimentation by dropping Mentos into different sodas and recording their observations.

4. Data analysis: After experimenting, students will analyze the data collected from their observations to draw conclusions about which soda had the highest reaction.

5. Conclusion: Based on their data analysis, students will conclude the reactions observed and the properties of the different sodas.

4. Texture:

- Definition: The feel or consistency of a surface or material, often described in terms of its roughness, smoothness, softness, hardness, etc.

- Example: Sandpaper has a rough texture due to the abrasive particles on its surface. In contrast, silk fabric has a smooth texture that feels soft to the touch.

5. Color:

- Definition: The visual perception of the reflection or absorption of light by an object, resulting in the sensation of different hues or shades.

- Example: The color of a ripe apple might be red or green, depending on the variety. This color is due to the wavelengths of light that are absorbed and reflected by the surface of the apple.
