Exploring Mass and Density Through Hands-On Experiments and Demonstrations

In this engaging lesson on mass and density, students will compare and contrast two images, leading to a deeper understanding of these concepts. They'll learn how to measure objects using a triple-beam balance, distinguishing between mass and weight. Demonstrations will illustrate density through various substances to show which float or sink in different liquids. The lesson culminates with students reflecting on the application of mass and density in their everyday lives, fostering a practical understanding of these essential scientific principles.

  1. Measurement: Mass and Density Day 5

  2. Analyze this Picture Directions: Write the following questions on the left-side of your notebook. Questions: Compare and Contrast the two pictures below. Give at least two reasons.

  3. Learning Targets • I can explain mass. • I can explain density. • I can explain density by examining objects floating and sinking.

  4. Mini-Lab: Mass Directions: On the left-sided, Answer the following question using the balance. Question: Using the triple-beam balance, measure the different objects your teacher has provided in grams (g). a). 1 Paper clip b). 5 paper clips c). Pencil d). Penny e.) metal mass f.) other objects

  5. Teacher and Student Demonstration Teacher will demonstrate how to use a triple beam balance and a digital balance. 2 objects 3 objects

  6. Different Balances

  7. What is Mass? Directions: On the right-side of your paper, write the question above. Under the question draw the illustration you see and the answer. Mass is how much you have of an object. It is not weight.

  8. Does the following substances have the same mass or different mass? Explain.. Water in a cup or Water Vapor

  9. Does the following substances have the same mass or different mass? Explain.. • 10 grams of iron or 10 grams of gold

  10. Teacher Demonstration: Density Which one Floats and Sinks? Coke Pepsi Diet Coke Diet Pepsi

  11. Teacher Demonstration: Density • Which one floats or sinks? Wood Tennis Ball Paper Flat Paper Balled-Up Metal Cubes Etc..

  12. Teacher Demonstration: Density • Which one floats and sinks? Cooking Oil Corn Syrup Water Liquid Detergent Alcohol

  13. Exit Slip • Name two ways you use mass and density in your everyday life..
