Please read the following before starting an exercise:
The topics of this exercise are "analyze and interpret evidence, understand food chain concepts, safe practices, forces and motion, use classification keys, analyze experiment variables, classify matter by properties".
If you need to study the topics, please do so before your exercise.
The exercise will take about 10 minutes. Our system starts to count time, when the exercise is loaded. Make sure you are not interrupted.
Select "Start Exercise" when you are ready. After you submit your answers, Beestar will grade your exercise.
analyze and interpret information to construct reasonable explanations from
direct and indirect evidence;

distinguish among producers, consumers, herbivores, omnivores, carnivores, and decomposers.

identify the forces that cause an object's motion.
describe the direction of an object's motion: up, down,
forward, backward. determine the effect of friction
on moving objects.

use classification keys to identify rocks, minerals, and organisms.
A classification key is an important tool used to help
identify objects and organisms. It consists of a branching set
of choices organized in levels, with most levels of the key
having two choices. Each level provides more specific
descriptors, eventually leading to identification.

analyze the variables in a simple experiment and identify
the manipulated (independent) and responding
(dependent) variables.

physical state, and the ability to conduct or insulate heat, electricity,
and sound;
