TODAY's VOCABULARY

Theory: an explanation of how things work, can be repeatedly tested within the Scientific method using observation, measurement, and evaluation of results.

Bean sprout: the sprouting seeds of certain beans, used in Asian cooking.

Hypothesis: An Educated guess ( a Cause-Effect statement, written in the format (If ..... then.....)

Drawing a conclusion: Stating the final results and solutions to the investigate problem or question
