Product Description

Interested in review osmosis with your students in a fun an interactive setting and reviewing the concept in mathematical detail? Look no further! This lab has students first predict, then observe and calculate and make conclusions.

Materials:

Gummy Bears (non-organic)

Heavily salted water

Scale

Rulers

Place the gummy bears overnight or longer for better results in 1 solution of salt water and 1 solution of regular water.

Students will initially make hypotheses about what they think will happen when the gummy bears are placed in regular water or salted water. They will also explain how they will know if their hypotheses are right based on what they will experiment with either the next day or in the same day.

Next or on day 2 (your choice) students will calculate the length, height and width of the 3 gummy bears with a ruler and then calculate the volume. Students will then get the mass by using a scale and weigh boat. Then they will calculate the comparison of volume and mass to explain their thought process in their conclusions.

Lastly students will make conclusions about their comparison of their calculated percent change in mass and volume, determine which had a greater percent difference and explain how osmosis explains that result. Students will apply their vocabulary and knowledge of hypotonic, isotonic and hypertonic to these gummy bears and predict what would happen if they changed the solution and what would happen!
