1 – 6 of 6 Classroom Resources

• Phase Changes, Reaction Rate, Reaction Rate, Chemical Change | Elementary School

### Demonstration: Plop & Fizz Investigation

In the demonstration the teacher will perform a reaction between water and Alka-Seltzer in order to generate the release of carbon dioxide. Students will observe the chemical reaction, while timing the release of carbon dioxide and observe 3 states of matter. This will be repeated 3 times, each time increasing the number of tablets used.

• Observations, Reaction Rate, Reaction Rate, Chemical Change | Middle School, Elementary School, High School

### Demonstration: Simple Kinetics

In this demonstration, students will see that different food dyes react with bleach at different rates.

• Chemical Change, Pressure, Conservation of Matter, Reaction Rate, Acid Base Reactions, Chemical Change | Elementary School, Middle School

### Lab: Rocket Challenge

In this lab, students will have the opportunity to construct a rocket, with the challenges of both designing it and preparing a chemical reaction for its “fuel” in order to propel the rocket over the furthest distance. Students will investigate available materials, quantities and ratios during allotted planning and testing phases. Student will record their plans, modifications and designs during the process. The lab will culminate with a competition amongst students to see whose rocket will travel the longest distance.

• Observations, Chemical Change, Reaction Rate, Reaction Rate, Catalysts, Chemical Change | Elementary School

### Lab: To What DEGREE Does it Matter

In this lab the students will explore how factors such as temperature may influence chemical reactions. Students will use citric acid and sodium bicarbonate (Alka-Seltzer) and a catalyst (water) to induce a reaction at varying degrees. Observations will be made of the rate at which the reactions take place under these varying conditions. The students will make predictions of how the temperature of the water will affect the chemical reaction. They will use a stop watch to time the reaction between the Alka-Seltzer and the varying temperatures of water and graph their observations for analysis, they will compare data to deduce whether temperature has any influence during a chemical reaction.

• Solubility, Physical Change, Phase Changes, Reaction Rate, Solute & Solvent, Molecular Motion | Elementary School

### Lesson Plan: Particles in Motion

In this lesson, students learn that particles that make up matter are in constant motion.

• Solubility, Reaction Rate, Solute & Solvent, Physical Change | Elementary School

### Lab: M&M's Solution

In this lab, students will investigate dissolving using M&M’s and will determine whether dissolving happens faster without assistance, or with the assistance of the tongue and teeth.
