The goal of science is to try to understand the world around us.
Scientists often work in groups so they can exchange data, which is extremely important in the study of science.
Understanding of science and the scientific approach is essential to intelligent decision making because it would make scientists make reasonable decisions and conclusions.
A control is the experiment set-up not containing any independent variable.
Analyzing data and drawing conclusions is to find out the result of the experiment.
It’s important to repeat investigations to identify errors and correct them. Scientific theories can always be proven wrong.
Seven shared characteristics of life are: cellular organization, homeostasis, metabolism, response to stimuli, reproduction, growth/development, and heredity.
The basic unit of life is a cell.
Homeostasis is the ability of a body to maintain stable internal conditions. Examples would include how we sweat and dogs pant.
Response to stimuli is the reacting to outside forces. An example would be how the Venus Flytrap would detect touch.
8 Levels of Organization: Molecules, Cells, Tissue, Organism, Population, Community, Ecosystem, and Biosphere
A light microscope would focus visible light waves. Light microscopes can magnify up to 1,000x and can see living things. Electron Microscopes would focus beams of electrons & can magnify up to 1,000,000x. Electron microscopes can only be used after water is taken out. Electron microscopes can see smaller than 0.2 micrometer.
A light microscope cannot magnify anything smaller than 0.2 micrometer.
Transmission Electron Microscopes can see thin objects and can reveal inner structures while Scanning Electron Microscopes can see 3D images.
