Technology Resources Needed: |
Internet/Computer/Projector Student technology device Teacher email address (optional) 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:
|
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.
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.
Elaborate/Extend: Students will answer questions either on paper or via computer email or app. Conclusion:

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:

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