Happy St Patrick's Day... #jcscience #density #PW2 #edchatie

The last week of physics revision for 3rd years. Building battety powered cars to bring together circuits #PW5, energy transformation devices #PW7 and distance time graphing #NOS4, #PW2 And more importantly a bit of fun! .🚙💨 #jcscience #iteachscience

Looks great. We're all looking forward to seeing this. Scheme of work is a great addition.

Revisiting electricity and simple electronics this week. Comparing current and voltage in series and parallel circuits #PW2 #PW5 #JcScience

Force meter attached to mousetrap arm.

Graph showing that spring force decreases with arm length.

3rd year students are investigating the forces generated by mousetrap catapults. Good practice on data collection and graphing skills. #JCScience #iteachscience

Anyone doing the immune system at the moment? Here's a simple printable card game to help reinforce key ideas. Clear your hand of pathogens but don't get stuck with an overactive immune response. #LcBiology #immune #iteachbio docs.google.com/presentation...

5th year biology students practicing aseptic techniques using yoghurt #bacteria. We'll see how well they've done in a few days! #lcbiology

Characteristic features of each kingdom.

Photos of example members of each kingdom, cow, fern, yeast, bacteria, amoeba

Starting bacteria and fungi soon. Here's a printable card sort activity to introduce the 5 kingdom and 3 domain classification systems. Have a go with your students and let me know how it goes. #LcBiology #Classification #iTeachBio #scienceteaching.

Hi Ciara, I certainly wouldn't be happy signing off that it's the students own work. As far as I know the ASTI have some motions around that for the annual conference. It's a bit unfair to put all of this monitoring on our shoulders. It's a huge shift from being"on the students side" so to speak.

Thanks Yvonne. Interesting times ahead. Doing sense organs with 5th years at the moment. Drew my last ever eye diagram on the board today. Out with the old...

The ISTA WhatsApp groups are a great innovation Humphrey, well done. Shout out also to Noel Cunningham for his science sharing group on Google. #edchatie

Good evening all. Science and Biology teacher in Dungarvan, Waterford. Past JCTscience associate and current associate with the Oide biology team. #edchatie

Students using the 'Moon Hat' today to model the different phases of the lunar cycle. #jcscience #ES4

EdchatIE A survey on the revived #edchatie discussions on Bluesky.

#edchatie folk - following last night's first discussion, a quick survey this week on topics, time and hosting.

pls repost rather than 'Like'.

Volunteers to host much appreciated...

Used Google lens today to identify plants and insects for ecology field studies and it's very accurate. No need for a specialist app. #lcbiology

Digital alcohol breath tester showing 1.5 g/l

Digital alcohol breath tester sitting in a flask of sugar yeast and water.

2 flasks in a water bath at almost 30 degrees Celsius. One flask has sugar, yeast and water.

Testing the vapour from a fermentation flask with a cheap alcohol breath tester. Gave a result of 1.5 g/l and a satisfying danger beeping sound.
It's difficult to get a positive result in the iodoform test for small quantities of alcohol. Each group got a beep so everyone is happy.

Garden flowers such as hydrangea or pelargonium work well. Boiled in water this time but you could also crush in ethanol giving a faster more concentrated extract.

Week 5: preparing oxygen using catalysts found in yeast.

Week 4: Preparing oxygen by using hydrogen peroxide and manganese dioxide.

Week 3: Preparing carbon dioxide by reacting HCl with calcium carbonate and measuring the rate of gas production with a gas syringe.

Week 2: Reacting magnesium and hydrochloric acid and testing the hydrogen produced with a lighting splint.

Week 1 early September: Extracting and testing acid base indicators from flower petals.

I'm going to do a series of posts here on activities I'm doing with 2nd year science students. (Year 9s in UK I believe)
