6th grade Common Assessment, Units1.1 and 1.2
- (6.1A) Students are doing an experiment in science class. Which piece of equipment will best protect the students’ eyes during the experiment?
- b. c. d.
- (6.1A) The reason for wafting or fanning a small amount of chemical vapors toward the nose as a means to detect odors in a test tube is to –
- Avoid experimental error from excessive loss of mass of reactant products
- Avoid splashing chemical into the face of any person
- Protect the nose and throat against potentially harmful vapors
- Determine the relative strength of the odor before smelling directly
- (6.1B) A glass beaker shatters on a table during a lab activity. What should the student do?
- Sweep the glass off the table onto the floor.
- Leave the glass alone until class ends.
- Brush the glass into the trash can.
- Ask the teacher for directions.
- (6.2B) After reading the passage above, determine which question the student is most likely trying to answer?
- Will seeds sprout faster in clear plastic cups or red plastic cups?
- How much water do seeds need in order to sprout?
- Do some kinds of seeds take longer to sprout than others?
- What is the I-Variable in this experiment? (what was different)
- The kind of cup
- The kind of seed
- How much water was used
- What were the constants that remained the same?
- The cups, the water, location and kind seeds
- The cups, the water and location of the cups in the sun
- The Scientific Method can be used ……
- At school in Science class
- At home to do a project like fix the lawnmower
- At work, when you begin working part-time, saving money
- All the above (a, b and c)
- (6.2E) For a science fair project, Jose did an investigation using bean seeds. He put 10 seeds with wet cotton in a jar (jar 1) and placed the jar in a closed cabinet in his room. He put 10 seeds with wet cotton in another jar (jar 2) and placed it in the dark, cold refrigerator. After a week, he checked the jars. Beans had sprouted in jar 1 from the cabinet. No beans had sprouted in jar 2 from the fridge.
Which conclusion can be drawn from the data in this investigation?
- Light affects the growth of bean seeds.
- Without soil, bean seeds will not sprout.
- Temperature affects the growth of bean seeds.
- Without moisture, bean seeds will not sprout.
- What was the I-Variable (independent variable)? (different)
- The seeds
- The location of the jars
- The time
- (6.4B) Which of the following activities would most likely require the equipment shown above?
- Catching fish in an aquarium
- Heating liquids
- Measuring outdoor temperatures
- Finding the mass of a rock sample
- It is ok to not wear your safety goggles or glasses if your eyes get itchy
- True
- False
- We always ‘reset’ the trays and materials exactly as we found them before we leave the room.
- True
- False
- Working ahead or touching lab materials is ok as long as you don’t break anything.
- True
- False
- If using hot plates, make sure the cords do not touch the hot surface.
- True
- False
- MSDS stands for Material Safety Data Sheet
- True
- False
