2. Lab Report Objective Materials List –All materials used in the experiment (even if used only once) Procedures Results –Data table and observations Discussion –Explain the results – What happened for you to get these results? How? Why?

3. Lab Report

4. Objective During this lab you will investigate the concepts of osmosis and diffusion using eggs

5. Procedures – Day 1 Obtain one egg per group Measure and record the circumference of the egg as well as its mass

6. Procedures – Day 1 Place the egg in a beaker. Pour in enough white vinegar to completely cover the egg. Record your observations

7. Procedures – Day 1 Store the eggs in the refrigerator for 24 hours

8. Procedures – Day 2 Obtain egg in beaker from refrigerator Record observations Return the egg in beaker to refrigerator for another 24 hours.

9. Procedures – Day 3 Carefully remove the egg from the beaker and record it measurements (circumference and mass). Write an explanation for your observations using the correct vocabulary

10. Procedures – Day 3 Determine the mass and circumference of the egg and record it in the data table. Pour 150 ml of corn syrup into its own beaker. Add the egg and store in refrigerator for 24 hours.

11. Procedures – Day 4 Remove the egg from the beaker and record your observations. Record the mass of the egg. Use a toothpick to pop the egg membrane and record your observations. Write an explanation of your observations using the correct vocabulary.

12. Review of Osmosis
