PRODUCT DESCRIPTION

★ ★ Can Eggs Float? ★ ★

Students will follow the scientific method to investigate the effect of salt on the buoyancy of an egg.

About This Activity:
I adapted this lab for my grade 6 students. The lab can be used in any science unit with the topic of buoyancy or can be used with the general scientific method/ measurement topic. The students will investigate the question: "How much salt does it take to get an egg to float in room temperature water?" They will make an "if...then...because..." hypothesis, follow procedures, and record their data in a chart.

Included In This Product:
♦ 2 page guided lab report- version A (with data chart for 2 trials)
♦ 2 page guided lab report- version B (with data chart for 1 trial)

Differentiating / Adapting for Your Classroom:
I have included two versions of this lab - the only difference between the two is that the first version contains two trials and the second version contains one trial. You can decide which version to use based on the measurement tools and time you have available. Note that using a Triple Beam Balance takes longer than a Digital Scale for this activity. I have done the lab with both and prefer digital scale.


Additional Materials Needed:
♦ salt
♦ water
♦ fresh egg (1 per group)
♦ something to stir with (spoon, popsicle stick, etc)
