Looking at variables

How many drops of water will a penny hold before they spill over?

That was our question today. Hopefully you had a chance to determine the answer. I also hope you had an opportunity to practice how to identify variables and controls during an investigation.

Tomorrow we will keep building on our skills by setting up a lab report.

No homework tonight. Please note that the quiz scheduled for tomorrow has been pushed back to next week.

Science skills

Oops! I forgot to post this before I left.

Observations and inferences are a huge part of a scientific investigation. We did some practice on differentiating between the two.

We also looked at how to write a good hypothesis. For homework countine working on the practice sheet that we started in class. Try your best to complete the problems. Remember that a good hypothesis should state the IV, the DV and a reason why you think the DV will respond.

The quiz scheduled for Friday has been moved. Pd1 Monday and Pds 2,4,5 Tuesday.

Fossil Hunt

Today we went on a fossil hunt. Students were asked to try and figure out what creature they "found" by working in groups and observing other groups ideas.

The goals of the activity were:

• to show the uncertainity of science
• how working together helps solve a problem
• to develop a hypothesis from an observation and test it

Homework: Complete questions for The Great Fossil Find.

Are you still stumped as to what the creature may be? Here's a hint: it liked to fly millions of years ago.

Draw a Scientist

That was our task in class today. The purpose was to look at stereotypes in science, where these ideas came from and debunk some of the ideas.
