Mrs. Delaney's Science Site: 7th Grade Science: Unit 1- Cells

Welcome to 7th grade Science!

The 7th grade science curriculum covers Biology (Cells, Nutrition and Human Body Systems), Chemistry and Astronomy!

General Announcements:

The Cell Test will be given on Wednesday, October 15th. This test is worth 100 points.

Students should study all of the material in their binder; notes, do nows, homework assignments, labs, and quizzes.

Extra help is available at lunch.

Study guide:

Safety Rules

Wearing the proper protection, following instruction, notify the teacher of any safety concerns, no horseplay, etc.

Metric conversions

using a ruler, converting cm to mm and mm to cm
Remember: to convert cm to mm, multiply by 10 and to convert mm to cm divide by 10

Scientific Method

problem, Research, hypothesis, experiment, analyze results, conclusion
picking out the variables (Independent and Dependent)
Remember: ________________ depends on _______________________

Microscope

Identify the parts of the microscope and describe their function
field of view / # that fit across the diameter

Cell organelles

mitochondria(where cell respiration occurs, ATP made), cell membrane (allows things in and out of the cell) and nucleus (control center) only

Characterisitcs of Living Things

Know the list of 6 items that classify something as living: made of cells, metabolic activities, movement, reproduction, responds to stimuli and growth and development

Cell Processes (Respiration, Diffusion and Osmosis)

the equation: glucose + oxygen --> carbon dioxide + water + ATP
In the Cell Respiration lab we used yeast and the indicator BTB- what does BTB indicate?
Diffusion and Osmosis I Lab: baggy in the beaker. What diffused in? out? What were the color changes?
Diffusion and Osmosid II Lab: Eggs in colored solutions. Why did the egg get larger in the blue solution? Why did the egg get smaller in the red solution?

Levels of Organization

Cell--> tissue --> organ--> organ system --> organism

Additional Cell Unit Review Sheet:

Science Quiz: Friday 9/19

Topics include:

1. Measurement

- using a ruler, converting cm to mm and mm to cm

- Remember: to convert cm to mm, multiply by 10 and to convert mm to cm divide by 10

2. Scientific Method

- Steps of the scientific method, vocabulary terms associated with scientific method (independent variable, dependent variable, control group, experimental group
