Hi All Has anyone ever tried this physics experiment and had any success? I have been trialing the experiment with Kundt's apparatus purchased from a science supplier with no luck. Love to hear if and how people have got this experiment to work. See video link. Shell :cheesy: https://youtu.be/qUiB_z...

Once the agar has set I turn them upside down and place them back into the bag the original agar plates came in and seal the bag with some tape before putting into fridge. I only seem to get condensation within the bag and not the plates. Hope this helps

Hi bigmack, our TAS dept is taking on all the programming and running of the new course but of course I have been roped in to help out with the practical planning from a science perspective. Will be interesting to see how it goes seeing as both teachers that were meant to be running it are now leavi...

Try southern biological, never had an issue with their agar (plain agar powder). Recipe I use is 10g bonox (beef extract), 10g peptone, 5g NaCl, 15g agar powder, 1L distilled water. Never had any issues with the supplier or this recipe. Agar plates should always be stored and incubated upside down t...

Hi all,
We are introducing the iSTEM course for year 9 next year. Does any one on here run it at their school? If so what experiments do you usually run for core module 1 & 2?
Thanks

No we don't sorry.

We got rid of all our dichromates about 5 yrs ago due to their carcinogenic nature.

Our method is:
Dissolve 2g phenolphthalein in 600ml ethanol. Make up to 1L with distilled water. Filter

Thanks, Jaycar had all the parts required to fix my issue

Hi All
Hoping someone can tell me where I can purchase another oscilloscope microphone with a BNC plug other than Serrata who don't stock them anymore.
Thanks

We use a videoflex (document camera) as it has an eye piece that fits onto the ocular of the microscope and projects the image under the microscope onto the smartboard. Works quite well. Putting an ipad/iphone camera over the eyepiece also allows for the students to take good pictures of whats on th...

Hi
we do it 2 ways. One way using 6%H2O2 and yeast and the other way is using 35% H2O2 and saturated potassium iodide. Link attached for the method we use with the yeast(just make sure you add the yeast to the warm water and mix well before adding it.
