Investigating the Relationship Between Water Volume and Height in Different Vessels
This lab experiment explores how the height of water in a beaker, Erlenmeyer flask, and test tube correlates with the volume of water added. Students will learn about the meniscus and utilize graduated cylinders to accurately measure water. The procedure involves adding increments of water (up to 50 mL) to each vessel and measuring the corresponding height to gather data. After plotting the height and volume relationship on a graph, students will analyze results and conclude with a Claim, Evidence, and Reasoning (CER) paragraph that highlights key findings.

Presentation Transcript
Problem: What is the relationship between volume of water and height in a beaker, erlenmeyer flask, and test tube. • Background –Explain or draw the following items and terms • Meniscus • beaker • erlenmeyer flask • test tube • Graduated cylinder • Independent variable • Dependant variable • Control variables
Procedure • Place the beaker on a flat surface. • Measure 10 mL of water in a graduated cylinder and pour into the beaker. • Measure the height of the water from the table to the meniscus. Record. • Measure 10 mL of water in graduated cylinder again and add to the already existing water in the beaker. • Measure the height of the water from the table to the meniscus. Record. • Repeat steps 4 and 5 until a total of 50 mL is in the beaker. • Follow the same procedure with the erlenmeyer flask and the test tube. • Graph the data for all vessels on one graph.
Data: (make a table for data collection) Data analysis: (make a three-line graph for each vessel). Conclusion: Write a CER paragraph to show the relationship between volume, and the height in each vessel. Claim-answers the problem/question Evidence-uses data from experiment to support Reasoning-provides why this happened… This shows that …. This is because…. This means that ….
