Can we “play” with electricity?

Human Ingenuity, Health and Social Education






LENGTH



2 months

CONTENT

Atom, ion, electric charge, everything is made of atoms

Atoms of different elements and their properties

Attractive and repulsive electric force

Electric field lines – analogy with magnetic field

Electrometer

To charge, to ground, to carry el. charge

Electric conductors and insulators

Production of electric charge – friction, heat

Electrostatic induction

Polarization

Lightning, protection against lightning

Electrostatic “toys”

Protection against electricity




OBJECTIVES/OUTCOMES



- safe work with static electricity

- discuss and understand that not all materials and object are able to live in different temperatures

- discuss the difference in thermoregulation between warm – blooded and cold – blooded animals

- describe and explain how we use different types of atoms in our daily life

- appreciate the need of different elements in our body

- present scientific information in format of leaflet and poster

- present scientific information on public – oral presentation

- formulate simple hypothesis, make simple experiments, describe it and state short result

- identify the possible danger of static electricity and protect against it

- work with different sources in appropriate way

- identify basic scientific components found in information from different sources

- explain and apply the information from static electricity to solve problems in familiar and unfamiliar way




ACTIVITIES

- reading from The Short History of Nearly Everything

- creating own electrometer

- playing with electricity (hedgehog from hair, the horses’ competition, electric circus, “jumping paper creatures”, “spell for snakes”, electric “toys”, balloon stuck on the wall)

- experiments with a can and aluminium strips

- worksheet – Static electricity – find and reject information from text – note taking

- making and observing experiments + giving predictions – experiments with electrometer – charging the electrometer, carrying the charge (through aluminium foil, plastic), grounding the electrometer, experiments with “magic bar” – ebonite bar

- research – what kind of materials like electrons and what material loose them easily?

- discussion about different elements and their usage in everyday life

- discussion - How different elements affect our body?

- work with sources – finding information and evaluation of them

- oral presentation of students’ work

- self evaluation and peer evaluation

-short writing – use of insulators and conductors in household

-essay writing – Static electricity around us
