In a science experiment, a student is asked to identify the freezing and melting points of water. Which piece of laboratory equipment should be used?

• Triple Beam Balance

• Thermometer

• Ruler

• Graduated Cylinder

Which of the following is the most likely food source for a carnivore?

• A plant

• The Sun

• An Animal

• A dead tree

Which statement describes how fossil fuels are made?

• Oil from Earth's core slowly rises to the Earth's surface and forms ponds

• Lava within some volcanoes becomes so hot that it transforms into fossil fuels

• Dead and decomposing organisms are exposed to extreme heat and pressure transforms them into fossil fuels

• When mountains form on top of coal, the pressure liquefies the coal creating fossil fuels

How are organisms, such as snakes, cacti and coyotes able to survive in harsh desert conditions?

• Over thousands of years these organisms have developed adaptations to survive in arid climates

• These organisms migrate out of the desert during the summer months

• These organisms work together to find sources of food and water

• Snakes, cacti and coyotes are all aquatic species that live in ponds and rivers during the hot day

Why is it important to form a hypothesis before performing an experiment?

• Developing a hypothesis ensures that the lab will be safe

• The experiment will take too much time to complete if there is no hypothesis

• The hypothesis tell what the experiment is go to be testing
