Remove all the beetles and replace them again in the middle of the two containers and wait five minutes and record data. Students know different plants and animals inhabit different kinds of environments and have external features that help them thrive in different kinds of places. Record observations and data with pictures, numbers, or written statements. Make new observations when discrepancies exist between two descriptions of the same object or phenomenon. Students know the position of an object can be described by locating it in relation to another object or to the background.
Students know there is variation among individuals of one kind within a population.
Make predictions based on observed patterns and not random guessing. Write or draw descriptions of a sequence of steps, events, and observations. Follow oral instructions for a scientific investigation. Students know sunlight can be blocked to create shadows. Repeat observations to improve accuracy and know that the results of similar scientific investigations seldom turn out exactly the same because of differences in the things being investigated, methods being used, or uncertainty in the observation.
