Lab Activity 1.1a: Observation Sheet for GrapeX

1. 
   Describe what the GrapeX mix looked like before you poured it into the water.
   

2. 
   Describe what happened as you mixed the GrapeX with the water.
   

3. 
   Describe what your completed product looks like.
   

4. 
   Identify problems with the procedures that you followed today. What were those problems and what could be done to fix those problems?
   

5. 
   Suppose the GrapeX was a liquid, life-saving drug. Would you trust it to save your life?
   

Lab Activity 1.2

How Much Food?

You work at Biogen, Idec with a group of scientists and engineers. Your team is making a new medicine that will help people fight diseases. Right now the scientists are debating how much food they need to feed the cells so that they continue to grow and create the proteins needed for the medicine. The scientists have decided to break into groups of 4 to conduct experiments to determine the right dosage for the cells. Each group will have a PFD that will list all the materials and equipment needed as well as procedures to follow. However, one procedure is missing. It does not list how much food to add to the cells. Each group’s job, is to determine the right dosage for the cells.

• 
  Use only the equipment that is listed on the PFD.
  
• 
  Use the observation recording sheet to keep track of how much food you have given the cells.
  
• 
  Describe the changes you see occurring in the container on the observation recording sheet.
  
• 
  When you have reached the right amount of food, write the dosage on the PFD.
  

How do you know if you give it too much food?

• 
  If you stir the broth and there is still food (baking soda) left on the bottom of the container.
  
• 
  In other words, there should not be any food on the bottom of the container.
  

Remember, if the cells get too little food or too much food then they will die. If the cells die, then the company loses money and they have to start all over again. This food is expensive so it is very important that your team uses only as much as needed to keep the cells alive and growing.

After each group has finished their experiment, all the scientists and engineers will form a whole group to discuss what they proper amount of food should be for the cells. The lab supervisor will then conduct the experiment using the proposed dosage to determine if the teams have discovered the right dosage.
