<span style="background-color: #000000; color: #ff00ff; font-family: Impact,Charcoal,sans-serif;">Our group has decided to make a petition on nuclear power plants. We are going to try to get 400 people to sign it.

<span style="background-color: #000000; color: #ff00ff; font-family: Impact,Charcoal,sans-serif;">Every member of our group will research facts about nuclear power plants to find out what negative effects that they bring to the enrvironment. We will also figure out ways to help make a difference in our society by helping to decrease the horrific amount of chemicals and toxic by- products that these plants produce.

February 22, 2012 Curiousity Lab- Indirect Observations

DEFINETION: __manipulation__- how you roll the marble __observation-__ what happens to the marble __inference__- what you think happened

WHAT WE THINK: __manipulation:__- we rolled the marble multiple times at different angles __observation:__- in some spots, it merely bounced off, other times it changed direction __inference:__- Susan and Taylor think the object will be a circle; Christy thinks that is a octagon; Aubri thinks it is a star or decagon

FINAL RESULT: The hidden object was an octagon.
