Really useful these boxes for storing all the experiments. They stack well and the different sizes mean that they are more efficient in the storage/space ratio. Makes easy to find as we work on an experiment on demand system. As the students arrive they say I learnt about this today but I didn't understand it, we didn't do an experiment, so we can rapidly get out the experiment and let the student carry out the experiment and lean by doing and by discovery.

Mobile phones in lessons
Many teachers don't like phones in their classrooms. Some are afraid their lesson could be recorded. I like my students to use their mobile phones in the lab. They record all my experiments. The good and the bad. My students Record the experiments, they take photos of the set ups. They enjoy taking Slo-mo of fast and not so fast events and using the phone as a microscope. Amazingly they usually organise themselves that one student does the recording and passes the files around. They act very responsibly and I have never had any problems. On the contrary the opposite is true. #STEM #Science #iteachphysics

Water Clock
I need a much better water clock to do this experiment Rule of odds - Todays job. A cart is rolled down the track. As it passes a bell it rings the bell. We try and make the time between each bell ring the same. As the cart is accelerating, the gap between each bell gets larger. in the ratio 1:3:5:7 etc Once this is set up then I use water coming out from a tap to fill up different measuring cylinders. The amount of water is in the ratio 1:4:9:16:25

DNA replication and Protein Synthesis
Its been a busy week of covering DNA replication and Protein synthesis, my models have been duplicated, copied and translated almost as many times as a real cell this week. @chatbiology #Science #STEM

Electrostatics
#Physics is all about learning about electrostatics. Learning about like charges repel and unlike charges attract is such a keystone fundamental idea. #iteachphysics #Science #STEM

Evolution Day
Its #EvolutionDay 162 years after the publication of The Origin of Species - A hard book to read. I like to show my students the fossils still in the rocks. #Science #STEM
