List 5 safety violations in this picture1. Goggles not worn on
eyes2. Girl is wearing open-
toed shoes3. Backpack and books
not put away4. Girl did not pull hair
back thus caught on fire
5. Boy drinking toxic substance
6. Boy did not clean up chemical spill
7. Chemical not to be disposed of in waste basket
List 5 safe practices shown in this picture
Intro to Physics: Day 3
1. Goggles are on and over eyes
2. Wearing closed toed shoes
3. Handling hot glassware with oven mitts
4. Safety apron is on and tied in back
5. There are no spills on the lab table
6. Lab area is clear of backpacks
What is the scientific method?
What are the parts of the scientific method?
Organized set of investigation procedures used universally to solve problems.
The difference between solving problems in science and real life situations is that we write the steps down.
