A great simulation to find thinking distance, breaking distance and stopping distance when you change the road conditions or the state of the driver. Use the sliders on the spreadsheet to change , for example the amount of alcohol that has been drunk or the degree of wear on the tyres. The activity can be run by students working individually or led by the teacher with the whole class. There is a worksheet for students to complete to help them develop their thinking. The simulation is also provided on an older version of excel (19917)

UV reactive beads change from white to coloured when exposed to ultra violet light and are wonderful for teaching reaction rates (so much easier than trying to work out when the cross has disappeared!) They are genuinely suitable for use with any age group and the notes here give ideas about how to carry out investigations at different levels. Post 16 students can use these beads to find activation enthalpy with a convincing degree of accuracy.

These resources are all based around BMI with an emphasis on data and handling. This is a sensitive subject and there are some teacher note to suggest how best to manage students as they measure their own BMI . There is a worksheet for students to record their findings along with some follow up work where they measure the BMI of some famous people - all fictitious data!

A teacher demo is used to introduce some student practical work comparing, by measuring mass, the amount of sugar in different soft drinks. Students will need to draw up a calibration curve and the practical work will help to develop their ability to use a burette accurately.

A simple worksheet designed for foundation students to help them distinguish between genotype and phenotype. No writing required!

This model was developed to teach the AQA astrophyics option at A level. The teacher sheet gives instructions for how to build a "working" model of a CCD in a couple of minutes from simple equipment you will already have. There is a follow up cut and stick worksheet for students to complete which consolidates the key ideas

There are two activities here. The first introduces the idea of temperature by encouraging students to compare the temperatures of different objects in the universe. The follow up experiment investigates where the energy from a hot object goes and helps students to think through ideas about energy transfer.

Combining ideas about scale and ratio with earth science, this pair of activities gives instructions for how to make a 3D model of Earth that can be sliced open to see its inner structure. It is followed up with a paper exercise where students make a scale drawing of our planet. The worksheet includes some extension questions for more able students.

Two activities here; an introduction that models how the pressure in gases is generated followed by instructions for students to carry out the collapsing can experiment - one of the most memorable pieces of practical work if a little wet! A follow up worksheet helps students think through the science behind the practical work

A fun practical activity that introduces the idea about accuracy of measurement and using the appropriate piece of equipment. The teacher sheet is backed up by a worksheet for students. It is aimed at keystage 3 students but is likely to be useful for less able keystage 4 students.

This set of resources leads students through an entire investigation into magnetism. WIth the help of the presentation they choose their own question to investigate. The teacher presentation provides suggestions, notes and an equipment list.

Here are some notes and ideas for teaching forces to help students think through these important concepts. The teacher demonstrations are followed up by a student worksheet to consolidate what they have learnt.

A great context for some investigative work and a fun experiment to carry out. There are background notes for teachers along with a link to a great website. For students there is a worksheet to help them think through all aspects of the investigation. Ideal for keystage 3 students to develop their skills.

A lesson on the important difference between cause and correlation. The teacher notes give details of examples where there is a strong correlation but no causal link, examples which can be hard to think of on the spot! The presentation is based around air pollution and helps students to understand the key ideas. It can be followed up with the worksheet which includes many examples. For each example students sort the three options given into correlation, cause or no link

Here are details of a practical investigation into the role of salt in preserving food that is simple to carry out and doesn't require much equipment. The results are quick and easy to analyse. To follow up there is a worksheet probing further into salt and human health where students calculate how much of the recommended daily intake is contained in various foods.

This is a hands on activity to help students consolidate and fully understand these important ideas. Students pass around pictures of 9 different types of cell and then complete the grid on the student sheet to show which of the genes listed will be switched on in that cell type. There is also a plenary activity designed to reveal any student misconceptions along with some teacher notes, with a link to a great animation which will explain the concept clearly to non-specialists

This introduction to the senses is a good introduction to the topic for keystage 3 students and also suitable for foundation students at keystage 4. There are instructions for a series of demonstrations and mini-practicals to investigate the human senses that are not easy to carry out but they are fun and thought provoking. Also in this package are student instructions for practical work to test the sensitivity of the skin along with a results table for them to record their findings.

This resource gives full details for teachers on how to carry out three demonstrations with alkali metals. It should be helpful for new teachers or those teaching out of their specialism 1. observing and comparing with other metals 2 reaction with water- the straightforward demo plus two further enhancements readily carried out in the lab 3 reacting sodium with chlorine There is also a table for students to record their observations.

After a discussion about what constitutes a species, students study pictures of ladybirds and record their observations. They decide how many different species of ladybirds they think there are. They then classify each of the pictures again using an ID chart and compare their findings.

It's hard to find much practical work to do around food chains. Here's a very active demonstration that turns into a student race and brings home all the key ideas that students need to understand. It's accompanied by a crossword puzzle.
