    It's a waiting game now - hatching

    Please do a bit of research beforehand in case one of your chicks has a disability. We hatched some guinea fowl at home and one had a deformed leg. We had to make a splint for it. It took us too long to sort it out and it died because it could not stand and feed itself. It was heartbreaking but...

    Hi all, has anyone made the micro rates of reaction equipment (Cleapss). I was wondering what you used to make the holes in the plastic. Do you have any tips for making them? Thank you

    Making states of matter syringes

    Thank you all for replies. I have now tried glue, which seems to work so far and also heating and sealing the nozzle, which also works. I might try the idea with the wire inserted next time, that sounds like a good way to release trapped air in the syringe. The real test is when these syringes...

    Making states of matter syringes

    Has anyone made filled syringes to show compression with solid, liquid and gas? I am not sure what glue to use to seal the end of the syringe. Is superglue any good? or maybe a sealant of some sort? thanks.

    Issue with HoD?

    Why not send all your department an email. Keep it light and short. Just say that you would like staff to call you by your first name rather than be called the technician (when there are no pupils around) as it makes you feel more part of the team. It is disrespectful of you HOY not to use your...

    My job was advertised yesterday

    It sounds like they have no idea of what you actually did as a science technician. We had a similar problem here, where they put out the wrong job description.

    Fermentation jar

    Just brainstorming here - how about a shallow, wide, see through plastic box with a lid? Holes drilled in for probes. It does not need to be glass or have an airlock. If it's quite wide, you will not risk the froth overflowing. You can find such boxes on the internet (we have some at home)

    Transition day

    How about chromatography using felt tip pens. It's easy, fun and they could take them home?

    Old Ammonia solution

    Ammonia rarely goes out in our school and we have old stock as well. Thinking of keeping just a small amount.

    I hate chasing orders that go 'missing' (My turn for a rant)

    Yes, same here, things go missing and deliveries get sent to wrong department.

    Telephone in Prep Room

    We wish we didn't have a telephone in the prep room. Ringing constantly with requests for us to drop everything and go and take messages to kids in classrooms, (11 classrooms, up and downstairs) It is expected of us. Been a bit easier in covid because we have a good reason not to cross bubbles...

    Schroedingers CLEAPSS

    Lucky your teachers are familiar with Cleapss, ours have hardly any idea or interest on what it is, despite us pointing them in the direction of the Cleapss risk assessment folder and suggesting they look at it.

    food burning practical

    We use old gauzes without the ceramic centres. We don't make any shape out of them, just use them flat on a tripod, boiling tube with water and thermometer clamped above. When the food is alight, just turn off the bunsen.

    Try the soaked wooden splints (Cleapss), they work and are very cheap.
