🌏EVERYDAY MYSTERIES-TAKE LEARNING BEYOND THE CLASSROOM AND INTO THE REAL WORLD.
Density is an important property in many materials engineering designs and applications. Why is the density of water maximum at 4 °C? How density changed by changing the temperature?
myViewBoard Originals - Density activities design based on the following learning objectives for teachers to let students practice and participate in the class after they learned:
- Students will understand why the density of water is maximum at 4°C.
- Students will understand the changes in water density and volume by changing the temperature.
- Students will practice calculating the densities of objects when given their masses and volumes.
- Students will conclude and explain that materials with densities greater than water will sink, while those with densities less than water will float.
- Begin with Video-assisted Learning to help build background and knowledge about anomalous behavior of water.
- Use animation-assisted to illustrate that decreasing the temperature between at 0 °C and 4 °C generally increases the volume, but there is notable reverse relationship to over 4 °C.
- Understand why density of water maximum at 4 °C.
- Practice the density formula. This science graphic organizer will aid students in identifying and defining mass, volume, and density and how they are mathematically related.
- Practice to calculate the densities of objects when given their masses and volumes. Arrange the objects in order by comparing densities.
- Practice to conclude that materials with densities greater than water will sink, while those with densities less than water will float.
- Hot and Cold Water Density Experiment to teach students How Temperature Effects Water Density. A collection of myViewboard Originals Backgrounds- Experiment Worksheet that you can download and edit for use in your science classes.
