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.

These three resources are intended to help students be clear about the differences between the two types of cell division. The Venn diagram activity should promote thinking and discussion and will allow teachers to spot misconceptions. There is also a colouring in worksheet where students identify the types of cells in each division and a simple fill in the gaps sheet. These would also be good revision tools

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.

Here are instructions and resources for four different hands-on activities that model how a synapse works. All are designed to help students think through the process and develop their understanding of how a synapse works. Choose the activity most appropriate for your students or give them a free choice. Also included in this package is a cut and stick worksheet to reinforce the effects of drugs on synapses.

"......I do and I understand". This role play is designed to help students really understand the circulatory system and how it works. As they move the oxygen and carbon dioxide around the different parts of the heart and body, students take the route taken by blood cells and learn by doing. To accompany the activity there is a suite of worksheets: - cut and stick boxes to put in the correct order - a simple worksheet to colour - a worksheet to label and add arrows to - a more difficult sheet where information about artificial valves is sorted and matched

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.

A teacher led demonstration activity to help students understand how errors in measurement are inevitable. The accompanying worksheet allows students to record the errors as they occur in the demonstration and then provides an opportunity to think through what they learnt.

Here students consider the genetic and environmental causes of variation by building a model human. Students enjoy making the models which make clear the different types of variation. There is a worksheet to use as a follow up to the activity which extends the key ideas and promotes thinking.

A very visual way of appreciating the carbon cycle and a great introduction to climate change. This board game shows carbon atoms cycling around the natural environment. It moves around the 3 main stores (plants, animals and the atmosphere) according the the roll of a dice, but overall stays in balance. However, when the game is repeated (by skewing the number of atoms that move for one number on the dice) the cycle goes out of balance. There is a sheet for students to record the movement of the atoms and notes for the teacher as well as Word and pdf versions of the board which can be printed onto A4 card of laminated.

This group of activities provides a fun and active way to introduce cells including building squidgy model cells. It includes investigative work to find out the conditions that cells need to grow best. All the activities are backed up by student worksheets.

Your students can use this simulation, written in excel, to investigate the factors that can limit the rate of photosynthesis. Move the sliders to adjust light levels, temperature or carbon dioxide levels before recording the length of the oxygen bubble produced. It's great for collecting data and then drawing graphs. There is also an accompanying planning sheet to help students think through the entire investigation. Remember to click on "enable content" when you open the spreadsheet.
