My freshman college students have restricted lab experiences from earlier grades. I keep in mind asking college students to measure water temperature they usually didn’t know which finish to place the thermometer in! Now, I’m not blaming earlier academics, their plate is full they usually have restricted entry to gear.
For this exercise, I arrange 6 stations within the lab for college students to carry out duties. For larger lessons, you’ll be able to double this quantity by repeating stations. College students can do the stations in any order as the entire a handout.
- Measuring quantity with a graduated cylinder
- Measuring size and quantity with a ruler
- Figuring out mass with a digital scale
- Measuring temperature with a digital and alcohol thermometer
- Transferring liquids with a pipet
- Studying security labels on chemical substances
College students take a few minutes at every station to carry out the duty and reply the questions. Supplies are straightforward to acquire in most labs (beakers, pipets, thermometers.)
In an earlier exercise that I take advantage of as an icebreaker, I’ve college students do a station exercise the place they guess the names and features of science instruments. They take a look at gadgets like Bunsen burners and take a look at tube clamps. It is a enjoyable approach to introduce them to science and meet one another as they focus on what every instrument is used for.
Later, college students will study fundamental laboratory expertise and figuring out controls and variables. These later experiments will use a few of the instruments they realized on this one. Additional actions coping with variables:
