Agenda: Warm – Up Bubble Lab Exit Ticket

Scientific Method Exploration Bubble Lab Scientific Method Exploration

Brainstorm What are the steps to the scientific method?

You will design an experiment to determine how to make the largest bubble What are some important things to think about when designing an experiment?

Bubble Lab Lab safety- be responsible in the lab No aprons, goggles or closed toe shoes are necessary Share the different wands Get into lab groups based on your row Discuss experimental design Make sure you have a control group Complete the lab and questions

Bubble Lab Discussion What problem is this experiment investigating? What was tested? What was your control? What did your data show? What are some sources of error in this lab? How could you minimize the error? What could have caused the inconsistent results? Was your hypothesis correct or incorrect? Why?

Exit Ticket: Explain how the bubble lab uses all the steps of the scientific method.
