Sugar Concentration and Density of Drinks
Written by Adi Ackerman, Head Teacher
"Sugar Concentration and Density of Drinks" is written for 7th Grade (Ages 12-13). A 6th grader who is already steady on matter can use it too, and an older student can use it as a short review.

7th grade science worksheet: graph density against sugar percent, then compare a sugar can and a zero-sugar can to explain sinking. Answer key included. Part of our density matter collection.
How do I use this worksheet?
Use the metals sheet to teach displacement, then the sugar sheet to graph and interpret. Students need a calculator for rounding to two decimal places.
What students will practice
- Students will plot density against sugar percent and connect the points.
- Students will read sugar percent for drinks from their graph.
- Students will calculate the density of two cans and explain which sinks.

FAQ
How do I use this density worksheet?

Use the metals sheet to teach displacement, then the sugar sheet to graph and interpret. Students need a calculator for rounding to two decimal places.
What does this worksheet teach?
⌄
Graph density against sugar percent, then compare a sugar can and a zero-sugar can to explain sinking. The directions on the page read: Read the text and the table. Plot the five points on the grid and connect them with straight lines. An answer key is included.
Can I use this density worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 7th grade matter, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.
How do you find the density of an object?
⌄
Density is mass divided by volume. Students find volume from the rise in water level, then divide mass by that volume.
What is water displacement?
⌄
Water displacement is a way to measure the volume of an object with no straight sides. Students read the water level, lower the sample in, read it again and subtract.
Why does one drink can sink while another floats?
⌄
An object sinks if its overall density is greater than the water around it. The sheet has students calculate the density of a sugar can and a zero-sugar can to see why.
