Discuss ideas with your lab partner. Decide on one testable question. Answer the prompts (see below). Conduct your experiment during class. Write a lab report sharing your results. Hand in one lab report per group. 1. What question do you have? 2. What is your hypothesis? (If….then….) 3. How will you test your hypothesis? 4. What will your control be? 5. What is your independent variable? 6. What is your dependent variable? Biology / Mendenhall

DESIGN YOUR OWN EXPERIMENT Sample Lab Report Name: _______________________________ Block: _____ POPCORN LAB PURPOSE To follow the steps of the scientific method and create a controlled experiment to observe what happens when alka seltzer is put into water. HYPOTHESIS If alka seltzer is placed into a 250ml beaker with 170 ml of water and 4 popcorn kernels then it will cause a reaction to occur and the popcorn kernels will float. MATERIALS ● 2 250 ml beakers ● 8 popcorn kernels ● 340 ml water ● 1 alka seltzer tablet PROCEDURE Two 250 ml beakers were filled with 170 ml of water and 4 popcorn kernels were placed into each. One beaker was labeled “control” and the other was labeled “experiment”. One alka seltzer tablet was placed in the experimental beaker. Nothing additional was placed in the control beaker. Observations were then made for three minutes. ● Dependent variable: activity of the kernels ● Independent variable: alka seltzer ● Control: beaker containing only 170 ml of water and 4 popcorn kernels ANALYSIS No activity happened in the control beaker. The experimental beaker had a reaction. The tablet began to dissolve instantaneously and bubbles began to form. After a few seconds the bubbles attached to the kernels and a few seconds later the kernels rose to the top of the water. After staying afloat for a few seconds they fell down. This cycle of up and down continued until the experiment was stopped after three minutes. CONCLUSION The hypothesis was supported by the data. The alka seltzer that was placed into 170 ml of water in a 250 ml beaker dissolved and caused the kernels to react. An alka seltzer tablet is comprised of aspirin, citric acid, and sodium bicarbonate. These tablets are stable when in solid form in the package. One possible reason for the observed reaction is that adding the tablet to liquid water causes the sodium bicarbonate and the citric acid to react giving off CO2, which then caused the kernels to float.

1. Prepare for class: Complete all homework on time. As soon as possible after class, add your own summarizing notes to your class notes. 2. Summarize what you have learned: Study the vocabulary list and important questions. Use the “study” methods that work best for you ­ these may include flashcards, writing summary note “cheat sheets”, graphic organizers, answering the textbook review questions, etc. 3. Study frequently and in small doses: Cramming does not foster long term understanding that will stick with you. 4. Set up a study group and study with friends: We learn 10% of what we read, 20% of what we hear, 70% of what we discuss, and 95% of what we teach others. 5. Ask for help: If you are having trouble with the material, get help early. Biology / Mendenhall
