Lab Safety
These are worn to protect our eyes when we are in the lab.
What are safety goggles/ glasses?
A process used to answer a question or solve a problem.
What is the scientific method?
Total distance traveled divided by the total time.
What is speed?
The force that pulls objects towards each other. The force that keeps us stuck to the ground. The thing that makes planets orbit around the sun.
What is gravity?
Energy of motion.
What is kinetic energy?
Loose clothing, dangling jewelry, and open-toed shoes.
What is the clothing we can't wear in the lab?
If we grow pea plants in sunlight and darkness, then the ones in sunlight will grow taller.
What is a hypothesis?
The quality that makes speed different then velocity.
What is direction?
Two factors that affect an object’s gravitational pull.
What are mass and distance?
This form of energy is stored and has three common types. One is based on the energy an object has stored due to its height. One is based on the energy stored in a compressed spring or a stretched rubber band. One is based on the energy stored in molecules.
What is gravitational, elastic, and chemical potential energy?
Sharing a candy bar during a science lab without permission.
What is no eating in science labs?
Has just one thing that changes. Has 2 main variables. Yields something we collect.
What is a controlled experiment?
Change in velocity. Change in speed, direction, or both.
What is acceleration?
One Newton (N)
What is the force needed to move one kilogram of mass at one meter per second squared?
Energy cannot be created or destroyed. It can be stored or transformed into other forms.
What is the Law of the Conservation of Energy?
Places we should keep our hands away from when working with chemicals.
What is our face and mouth?
The results show the car with the highest mass rolled farther than the cars with lower mass.
What is the analysis?
__________ is the speed of a car when it has traveled 84.62 km in 2 hrs.
What is 42.31 km/h?
If an astronaut has a mass of 110 kg on Earth, then their mass while floating through space, with no gravity is ___________.
What is 110kg?
Kinetic Energy = 0.5 x mass x velocity ^2
The kinetic energy of a 2kg bird flying North at a velocity of 12 m/s.
What is 144 J?
Using two hands, one on the arm and one on the base.
How do we carry a microscope?
Find a book on the subject. Talk to a scientist who studies the subject. Talk to engineers. Credible Online Sources.
What are resources for gathering background information?
A car accelerates at ______________ when it accelerates from rest (0 m/s) to a speed of 155 m/s, within 5 s.
What is 31 m/s2?
Steve lives at the top of a 4,000 m mountain, and his bulldog Doug weighs 35 lbs. When he took him to the vet, they said Doug weighed 37 pounds. He weighed Doug and took him to the vet on the same day. There is a factor related to gravity that affected Doug’s weight.
What is Doug's distance from the center of the Earth?
Gravitational Potential Energy = Mass x 10m/s x height
The potential energy of a 0.2kg bat hanging 15.3 m above the cave floor.
What is 30.6 J?
