Mobiles for kids?
Type: Activity
Learning Strategy: Group discussion
Topic: Electromagnetic radiation
Should youngsters have their own mobiles? The government's adviser on radiation thinks not. Suppliers are listening. The first mobile targeted at 4-8 year olds has just been withdrawn. There were concerns about health risks. But what proof is there that the mobiles are harmful? Opinions are divided and the evidence is inconclusive. This is not an unusual situation. The first evidence for a link between smoking and lung cancer was also very uncertain. Policy makers usually follow the precautionary principle. They issue warnings at the first hint of danger. They would rather be safe than sorry. Should we take their advice? Are mobiles are harmful? In this discussion activity, students judge the strength of the evidence.

Learning objectives
Students will examine evidence about mobile phone health risks and decide whether they would allow a young child to have one.

Running the activity
Suggested time: 15 minutes
Suggested starter: Ask students how long they spend talking and texting on their mobiles in a typical week. Invite them to talk about health risks they have heard of that are associated mobile phones.
Main activity: Project page 1. This includes newspaper headlines to set the context and an outline of two ways mobiles could damage health. It also introduces a dilemma – should Jack (12) let his sister Emily (8) have a mobile for her birthday, or would he be putting her future health at risk?
The pupil task is described at the top of page 2. The rest of the page provides a set of Evidence Cards. Divide the students into small groups. Each group will need a set of cards. Ask them to discuss the evidence for and against mobiles being safe for youngsters. They should pick out the three most compelling scientific reasons for and against. Then decide whether Jack's sister should get her mobile.
Possible plenary: Ask students to vote yes or no to the question: If there was clear scientific evidence that using a mobile phone could double your chance of getting a tumour, would you [still] use it?
Background Notes: According to Sir William Stewart of the National Radiological Protection Board, author of the 2000 Stewart Report on mobile phone safety, parents should not give phones to children under 8 and should urge those between 8 and 14 to use mobiles only when absolutely essential. 25% of 7-10 year olds own mobiles. Scientists have yet to find proof that the electromagnetic radiation they transmit is dangerous, but Prof Stewart said that new evidence suggested there might be health implications. The radiation frequency is just at the border between radio waves and microwaves. Children are at greater risk than adults because their skulls are thinner and their nervous systems developing. They will also have longer lifetimes of exposure.
The cards reflect some of the arguments above, as well as including some non-scientific reasons. One argument appears as both a reason 'FOR' and 'AGAINST' – this is deliberate, and is designed to get students thinking!

News links
- BBC news
- This is an excellent and accessible summary of most of the key issues.
- Stewart Report
- This is part of the Stewart Report. It is interesting teacher background information, which is very clearly written (but extremely long and technical!)
- The Guardian
- This is an article in the Guardian summarizing the main issues. It has more manageable teacher background than the Stewart report and accessible to students with good reading skills

I couldn't download the activity sheets, so didn't use it in the end after spending hours trying.

I taught this to a group of y10 students in a special school. I used it as it stood and with TA support most of the children were able to sort most of the statements.
It served as a useful introduction to our work on the electromagnetic spectrum.

i used this activity as a revision exercise for AQA P1b with middle ability Year 10. They loved it. encouraged a lot of discussion and thinking!

Some struggled with having so much to read, but it generally was appealing to the students. Provoked some great discussions.

Science In The News Skills

I used this activity with a low ability year 10 GCSE group. The scenarios on the cards were very useful in getting students to think about not only whether the information was for or against mobile phone use, but also if the info was valid or reliable. This is something they often get wrong when they write up their Science In the News Tasks.

I found this an excellent activity for teaching AQA 'how Science works' and assessing value of scientific evidence. Kept entire class on task and talking about science

Good resource outlining the pro's and con's of mobile phones. Used with year 10, 21century science to form start of case study. pupils liked it and could utilise their findings.

Worked well as a short activity to introduce the issues for a single science Y10 set. They came up with some interesting ideas (as well as yes and no, some students felt she could wait until she was older to have the mobile), and it was a good way to review benefit and risk for 21st Century Core Science.

I used this with a weak group of single science pupils doing entry level for the digital age unit and it worked well.

Engaged year 9 students who are normally not interested in participating. Worked well also with motivated and able year 9s, and with middle-ability year 10s.

mobile Phones for childres

I tried this with my year 10's and the pupils found it engaging. As i walked around the room the different groups were discussing the different points as to whether or not the girl should have a phone. In the end everyone decided she wasnt going to get the phone for different reasons. Its a good discussion topic.

Have just used this with low scientific ability year 10 as part of the newAQA science course (Physics 1b). They were quite engaged in this task and I extended it to the production of an information leaflet for parents. Initially they found it quite hard to focus on scientific reasons, being more interested in the social and personal security aspects, but most moved on to showing some scientific awareness by the end of the lesson. I also provided them with the first 2 pages of the BBC site which gives some pros and cons.

Tried it with mixed ability year 7 group. Went very well, kids were able to understand the points well and sort them out into for/against pretty quickly. Didn't spend too long debating points, but did get them to do a "continuum" afterwards to review their position on wether phones are OK or not for young children.
Good activity.

We used this activity for year 10 students aged 14 to 15., many of whom have found science difficult and, in some cases, irrelevant. They found the activity interesting and engaged with the concepts. The instructions were clear and the teachers found it easy to use. We laminated the cards and used the activity as part of a unit on minerals and their uses in everyday life. The activity gave the students and opportunity to engage with wider scientific issues and their use in informed decision making

Emily's mobile phone
May 24th, 2005
My top set year nine class found this activity very engaging, and it encouraged them to talk to one another about the scientific uncertainties and to discuss the facts.
Most groups came to the view that Emily should not be given a mobile for her birthday. They recognised that some arguments on the evidence cards were more persuasive than others, which led to interesting group disucssions about the nature of scientific evidence and what constitutes 'proof'.
Following the activity we used the link to the bbc.co.uk website to get more information - I gave students a printout of the information (which could perhaps benefit from being edited for year nine as it is six pages long) and they had to find further evidence to back up their point of view. If they came across evidence that contradicted their point of view, I asked them to think of a counter argument that they could use in a debate which I have planned for a subsequent lesson.
