Hemel Private Tuition

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

#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

Its that time of year to cut up the red cabbage and make red cabbage indicator. Fun but smelly.

Blend a leaf of red cabbage with 100 ml distilled water. Filter (cheese cloth recommended). The resulting solution displays pretty much a full range of colours from pH 1 to14. Some people recommend b...

Mixing the same solution using different methods, by hand, using a magnetic stirrer and a vortex mixer. Which is best ? I find out #iteachphysics #iteachchemistry #Science #STEM

Learning how to use a pipette and get the meniscus at the correct level. This certainly takes some practice. #iteachchemistry #Science #STEM

Determining the Molecular weight of a volatile substance using the steam generator. Problem here is making the students wait until it is hot enough. A known amount of a volatile liquid is injected into the gas syringe at 100C. The volatile liquid evaporates and turns to gas and the volume is meas...

#Physics Much of the usual fun with conductors and insulators. Both are at the same temp but the metal feels colder. Interesting answers of why. #iteachphysics #Science #STEM

Investigating catalysts. Letting students do some experiments that they have not seen or done in school. Doing is so much better than watching or worse reading from a book. Decomposition of Hydrogen Peroxide using a Manganese dioxide catalyst. After the reaction filtering washing and drying the c...

Looking at Force x Distance Problems with Year 12 #Physics. The @pascoscientific Meter Stick Torque Set is extreme sensitive. We were using 1g masses to balance 100g but I may need some .5 or .25g masses #iteachphysics #science @chatphysics
