Students will be able to:

-justify why it is important to be organized and observe rules in a science class.

-identify how science is useful in solving everyday problems.

-critique laboratory activities for safety.

Students completed the following bell ringer:

Gregor Mendel was able to figure out a great deal about how traits are passed from one generation to the next by studying garden peas. He grew thousands of pea plants and counted and recorded the traits of all the peas they produced in order to do this. Why did Mendel grow and use so many peas to conduct his experiment?

A. Having many replicates in an experiment decreases the possibility that chance will affect the outcome. B. Many pea plants are identical, so in order for Mendel to ensure variety in his findings, he had to use thousands of pea plants. C. Other scientists do not need to repeat the experiment if there is sufficient data gathered during the initial experiment. D. Mendel was overly cautious and grew far more peas than he really needed in order to prove his hypothesis

Students' notebook covers were checked. 

Textbooks were distributed. Students were instructed to read pages 290-295 and answer ALL questions/complete ALL information in the text. They are also to write the following on loose leaf paper, correctly headed:

Home learning 2: page 294 do the math (1-3) and page 295 (Virtual lab-Using Density)

HL 2 is due in class on Monday/Tuesday.

Students worked in their interactive notebooks and are responsible for pasting all pages in the front. The notebook should be completed by Monday/Tuesday of next week.

Students began a discussion in the differences between mass and weight.
