### sense in the lessons

In science, nuts are seeds of trees; squirrels collect and bury them, and some grow into new trees. In health and safety, some people have a nut allergy that can be very dangerous, so many schools are nut-free; never share food with someone who has an allergy. In design and technology, nuts and bolts hold things together. Phrases: «nut allergy», «nut-free», «nuts and bolts» (basic facts), «a hard nut to crack» (a hard problem), «go nuts» (go wild), «in a nutshell» (very briefly).
