Title:

My Gummy Bear is Bigger than Your Gummy Bear!

Overview/Annotation:

Students will develop an understanding of volume and density by analyzing, calculating, and measuring a gummy bear. The students will determine the cause and effect of a water-soaked gummy bear. Students will measure water and gummy bear with accuracy, record data, and communicate their results.

This lesson results from collaboration between the Alabama State Department of Education and ASTA.

Grade: 5
20 ) Recognize volume as an attribute of solid figures, and understand concepts of volume measurement. [5-MD3]

a. A cube with side length 1 unit, called a "unit cube," is said to have "one cubic unit" of volume, and can be used to measure volume. [5-MD3a]

b. A solid figure which can be packed without gaps or overlaps using n unit cubes is said to have a volume of n cubic units. [5-MD3b]


NAEP Framework
NAEP Statement::
8M1h: Solve problems involving volume or surface area of rectangular solids, cylinders, prisms, or composite shapes.


Science
SC2015 (2015)
Grade: 5
5 ) Construct explanations from observations to determine how the density of an object affects whether the object sinks or floats when placed in a liquid.


NAEP Framework
NAEP Statement::
P4.3: Matter exists in several different states; the most common states are solid, liquid, and gas. Each state of matter has unique properties. For instance, gases are easily compressed while solids and liquids are not. The shape of a solid is independent of its container; liquids and gases take the shape of their containers.

Scientific And Engineering Practices:
Constructing Explanations and Designing Solutions
Crosscutting Concepts: Cause and Effect
Disciplinary Core Idea: Matter and Its Interactions
Evidence Of Student Attainment:
Students:
  • Use data from observations to explain how the density of an object affects whether an object sinks or floats when placed in a liquid, like water.
Teacher Vocabulary:

  • observe
  • explain
  • sink
  • float
  • mass
Knowledge:
Students know:
  • Objects are made of many tiny particles to small to be seen.
  • Some objects have many tiny particles compacted close together that causes the object to sink while other objects the same size may float because their tiny particles are less compact.

Skills:
Students are able to:
  • Predict the results of different types of objects being placed in water. Test the objects and communicate the results.
  • Use appropriate tools (Scale, balance, ruler, or graduated cylinder) to measure the weight, mass, and/volume of an object.
  • Construct an explanation to describe the observed relationship between density and the ability of an object to sink or float.

19. Relate volume to the operations of multiplication and addition, and solve real-world and mathematical problems involving volume.

a. Use the associative property of multiplication to find the volume of a right rectangular prism and relate it to packing the prism with unit cubes. Show that the volume can be determined by multiplying the three edge lengths or by multiplying the height by the area of the base.

b. Apply the formulas V = l x w x h and V = B x h for rectangular prisms to find volumes of right rectangular prisms with whole-number edge lengths in the context of solving real-world and mathematical problems.

c. Find volumes of solid figures composed of two non-overlapping right rectangular prisms by adding the volumes of the two parts, applying this technique to solve real-world problems.

Students may use his or her technology device to record data results, take picture, and/or email conclusion questions to teacher. Teacher will need to provide an email address for students to send answer via email. If teachers use Google Classroom, the question can be uploaded, and students can respond.

Background/Preparation:

For Teacher:  The teacher must be knowledgeable about the following:

  1. Density of a material is defined as its mass per unit volume. 
  2. Volume of water is different and has specific and unique mass.
  3. The mass of water is expressed in grams (g) or kilograms (kg), and volume is measured in liters (L), cubic centimeters (cm 3), or milliliters (mL).

 
  Procedures/Activities: 
Engage: 
Students will measure the length, width, and height of a textbook to review how to measure correctly.  Students will calculate the volume of the book. Volume = length x width x height.     
 
Video, “Our Density Song.”  Students will sing and review the definition of density by singing along with the video of middle school students. Students will find the density of the book.

Students will begin “Gummy Bear Lab” by following directions on the form.  Depending on class experience, the teacher may want to have students conduct each step together as guided inquiry or may choose to let this be an inquiry lesson.

Question:  What do you think will happen to a gummy bear when you put it in water over night?

Hypothesis: ___________________________________________

Plan:   Choose one gummy bear.  Take a pencil and draw around gummy bear on paper before continuing on. Put the bear in a cup labeled with your name and class period.  Use the equipment available to measure your gummy bear and record the data in the chart for Day 1.

Measurements:  Measure to the nearest tenth of a centimeter.

  1. Measure the length from the top of its head to the bottom of its feet.

  2. Measure the width of the widest point across the back of the bear.

  3. Measure the height from the front to the back at the thickest point.

  4. Calculate the volume by multiplying the length, width, and height.

  5. Measure the mass using a triple-beam balance or other scale to the nearest tenth of a gram.

  6. Calculate the density by dividing the mass by the volume. D = M/V

  7. Add 50 ml of water to the cup and allow it to sit overnight. Place cup in designated area.

Make sure students record data on a chart. 

 

Explain:

On Day 2, carefully remove the gummy bear from the cup of water and use a towel to dry it off to prevent it from dripping.

  1. Repeat the measurements, and record your data in the correct portion of the chart.
  2. Subtract the amount of change for each measurement and record in the chart.
  3. Students will explain the difference in the size of the gummy bear.

 

Elaborate/Extend: Students will answer questions either on paper or via computer email or app.  

Conclusion:
  1. Was your hypothesis correct? Why or why not?
  2. Which change is greater, volume or mass? Explain.
  3. Was there a change in density? Why?
  4. How do your results compare to those of your classmates?

  Assessment  

Assessment Strategies

This lesson will be assessed based on correctly answering questions with reasonable answers. 

Assessment: The teacher will observe students as they measure, calculate and conduct the experiment to see if the evidence supports the explanation that density affects the ability of an object to sink or float.

Assessment: Students will answer questions on the form to check for understanding.  The teacher may choose to let students answer the question by emailing it or uploading to app or Google to the teacher. The teacher will need to provide an email address for students to send answer via email. If teachers use Google Classroom, the questions may be uploaded so students can respond.

Acceleration:

Students can begin to test other objects, for example, a golf ball.

Question:  How many spoonfuls of salt will we have to add to make our golf ball float?  Why will salt water make

Prediction:

  1. Add your golf ball and record what you see.
  2. Using your spoon, remove the golf ball and place it on the napkin.
  3. Add one spoonful of salt to your water and stir until the salt is dissolved.
  4. Test the golf ball to see if it floats. If it floats stop and record the amount of salt next.
  5. If it sinks, remove the golf ball and another spoonful and repeat the process.

What I Learned: 

  1. What did we change the density of? 
  2. What happens to objects with a higher density? 
  3. What happens to objects with a lower density? 

Intervention:

Students who need extra support may be assigned to a partner who is sensitive to the needs of that student.
