3. scientific journals, online chat
4. The bacteria had to enter the flask through a long tube or a trap
5. The effect of Pasteur's investigations are that people now eating healthier and scientists are keeping their work areas more clean.

Laboratory Skills 1

PRE-LAB DISCUSSION
1. Bacteria or chemicals could get on them and make or sick, or worse.
2.So you know what you're doing, what supplies to use, and where the supplies go.
3.gloves,aprons, goggles.
4.wash your hands, put the supplies back where they were after cleaning them, turn off burners.
5.no
PROCEDURE
1.Handle breakable supplies carefully, don't touch broken glass
2.Working with fire
3.Use the heat-resistance gloves
4.Poisonous materials
5.Safety goggles
6.Sharp objects, able to cut or puncture you
7.The material could shock you
8.Use caution while working with animals
ANALYSIS AND CONCLUSIONS
1.The person in the drawing is working with heated liquids and is not wearing goggles.
2.She has the tube pointed at her, and the liquids in the tube could spray out at her.
3.He has a lid on a heated tube, which could cause the gases to blow the container apart, injuring him or anyone around him
4.She is eating near the experiment, and this could contaimenate her food or drink and make her sick, or worse.
