Year 4 Fir Science at TCS

As part of science week, year 4 were invited to take part in a science lesson at TCS.

They were very impressed with the facilities and resources on offer in the science lab.

They carried out a variety of experiments and witnessed chemical reactions involving hydrochloric acid and magnesium. They also made a special goo using pva glue mixed with chemicals.

Can you remember why the magnesium caused the test tube to heat up?
