How the World Works: Does it Matter
Central Idea: People use their knowledge of properties of matter to suit specific needs.
Line of Inquiry: Conditions that cause reversible and irreversible changes in matter.
Learning Intention:
To describe the structure of particles in a solid, liquid and gas.
Students commenced by first formulating a testable question: does the temperature of water affect the food dye powder?
Groups then planned for an investigation, showing awareness of variables with guidance from the teacher. They determined that the temperature of the water (hot, room temperature, and cold) will be the variable that is changeable whereas the amount of food dye powder and the amount of water will be the controlled variables. Students were able to make a simple prediction about the outcome of the experiment.
After completing the planning process, students carefully measured the temperature of water in each beaker. One group measured the temperatures to be 15 degrees Celsius, 20 degrees Celsius, and 48 degrees Celsius. In excitement, they added the food dye powder to each water-filled beaker and observed the changes. One member of the group was responsible for measuring the time it takes the powder dissolves.
Groups essentially agreed to repeat the experiment as they reflected to use less amount of powder to allow faster dissolving time.
