Week 2, Day 2

Read and follow the steps below.  Record in your science binder as directed.

Engaging Scenario:

Jessie is excited when she hears the phone ring. She answers and hears her aunt’s voice calling from California. “I want you to come visit,” she tells Jessie. “I’ve already made flight reservations for you for this weekend. I can’t talk long. Quick, write down this flight information.” Jessie fumbles around for a pen and paper. She cannot find any so grabs a black marker and finds only a paper towel to write the information down. She hangs up the phone and runs to tell her mother, leaving the paper towel on the kitchen counter next to the sink. When she returns her heart sinks. The black writing with flight times has disappeared and in its place are many smudgy colors on a very wet napkin. What happened? She emails her aunt to get the information again, but still wonders, “what happened?”

Jessie decides to experiment in the kitchen a bit. She wants to replicate what happened.  She searches for the black marker and a paper towel.

What is the question that Jessie is trying to answer?  Write down the question in your science binder

What do you think the answer is to the question Jessie is trying to answer?  Write down your hypothesis in your science notebook

How might she design her experiment using the following materials?  Write down the materials and a step by step plan to solve the question in your notebook 

1 strip of paper towel

1 black marker (water color, not permanent)

1 paper cup

1 pencil

What happens to a black marker line when it gets wet?  Come up with a plan to answer the question.  Write it down in your notebook. Set up a table to collect results, and write down your results in your science binder.  Collect data over a ten minute period.
