Really awesome science demos/labs?
 
That can be done in 45 minutes or less?

I have a generous budget for my co-op class. I'm so used to being frugal but I'd like to do some really fun things that these kids might not get to do at home because of cost.

Or just any really fun science labs you've done, even if they weren't expensive.

It's 4th-8th grade. My class is an hour but I have to budget for set up and clean-up.

I have 24 students and we often do labs in groups of 4. I can't do anything that has to sit overnight. Other groups use the room during the week.

I do have access to a kitchen but I prefer not to bring the whole group in there. But I can heat things up, etc.

Not me, but a woman who taught at that same Co-op that I did last year did cool experiments with her middle school students.

They grew geodes in egg shells

Ice cream in a plastic bag is something my friend who is a chemistry teacher did at my old school.



I wish I could remember more.

Not 100% sure if these are short enough but our classes were only an hour long, so... :shrug I mean, take them
Or leave them ;)

Figured no one else responded yet and I’d try to throw some ideas out to be helpful or provide inspiration :)

Dissection! My kids homeschool program does dissection with 3rd-8th graders. They have a whole lab safety contract and work in groups on animals that are related to whatever they're studying that semester (ex. fish, owl pellets, squid, flowers etc...). You'd need the trays and safety goggles and dissection tools. It is really fun and memorable.

Owl pellets - my kids alone easily spent 45 minutes finding and identifying bones and trying to make a skeleton.

Polymers - slime, shrinking chip bags, etc. I'll ask my friend what resource she used.

I was thinking disection as well. When early bird did a frog earlyer she didn't spend more than 45 min on it.


What about engendering things. Like egg drop or bridge building or mousetrap cars. Some of thoes migh take longer than one class but it could all be taken home and brought back if that is pocible.

My friend used this book, The Elements for a jumping off point. Then looked on pinterest to find activities.

She also went to Home Science Tools to get supplies.

She did a really cool one where they burned different elements/chemicals and watched the flame color to determine what was being burned. :tu :tu

Thanks for all the ideas!
