Monday/Tuesday, 22/23 October, 2012

This is HL 18. Answers only on your own paper. Follow the directions printed on the page.


Students will be able to:
-distinguish between protons, neutrons, and electrons.
-explain that atoms are the smallest unit of an element and are composed of subatomic particles.
-describe how the atomic theory was developed.

Students used the collaborative structure Showdown to answer the following bell ringer questions:

Scientific knowledge may change as new evidence or information is discovered. Which of the following would NOT be a result of new scientific research and information?
A. Binomial nomenclature is assigned to a recently identified plant species.
B. An endangered monkey species is put in a reserve for protection from extinction.

C. A newly discovered chemical element will be added to the periodic table of the elements.
D. A nonnative plant species will begin to reproduce rapidly after being introduced into a swamp ecosystem.
Keesha did an experiment to study the rate of photosynthesis in the water plant Elodea.
She placed a piece of Elodea in a beaker of water and set the beaker 10 centimeters (cm)
from a light source. Keesha counted the bubbles released from the plant every minute for
five minutes (min). She repeated the process two more times. First, she moved the light to
20 cm from the beaker, and then she moved the light to 30 cm from the beaker. Keesha’s setup and data are shown below.

                

What is the outcome variable (dependent variable) in this experiment?
A. the number of bubbles produced

B. the type of plant placed in the beaker
C. the distance of the light source from the plant
D. the amount of time the bubbles were counted

Students submitted HL 17 and their reading assignment. They also received HL 18, which can be found at the top of this blog.
Students submitted their atomic model projects.
Students completed the Have A Ball lab and submitted it.
Students watched a BrainPop movie on atoms. 
Students then worked in their interactive notebooks, pasting in past work such as the mini-assessment 2, the GIZMOs on Phases of Water and Element Builder, and today's notes on Atoms. Students should also include all home learnings in their notebook. 
Students should complete the notes at home by drawing something to represent the atomic model, writing the 3 Costa leveled questions, and finding the corresponding answers with their highlighters (3 questions, 3 colors). Students should write their summary at the bottom of the page.
