This resource for Key Stage Three students provides detailed information about each food type and gives examples and daily portion allowances. The resource would link to studies about food, diet and health, and the life processes and nutritional needs of humans. 

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Identify pairs of forces that are balanced or unbalanced.

• Calculate the size and direction of the resultant force of two forces acting along the same straight line....

This resource asks pupils to apply their knowledge of forces, resultant forces and the affect of forces on the motion of an object. The first task checks pupils' ability to be able to interpret force arrows to describe qualitatively the motion of a lorry and calculate the resultant force.  Pupils are then asked to...

With this simulation students can move objects on a seesaw to learn about balance and test what they have learned by trying the Balance Challenge game.

Sample learning objectives include:

*Predict how objects of various masses can be used to make a plank balance.

*Predict how changing the...

A Year Ten module from the Salters’ double award GCSE science course. This module deals with interactions between species in ecosystems. Students are shown how stable conditions lead to a natural balance in populations and how human activities can disturb this balance....

With this simulation students can explore the conservation of mass and balance chemical equations. Sample learning objectives include: *Balance a chemical equation. *Recognize that the number of atoms of each element is conserved in a chemical reaction. Describe the difference between coefficients and subscripts in...

From the Centre for Science Education, and with support from Shell Education services, these materials help children to investigate forces and balance.

The materials contain a clown shape to colour in and cut out. The shape is then weighted with steel washers and balanced on a taut piece of string. Once...

This activity can be used to explore the relationship between shape and hydrodynamics (resistance).

Curriculum links include aerodynamics, resistance, forces, buoyancy and thrust. There are a number of useful links to...

From the Centre for Science Education, and with support from Shell Education services, these materials help children to investigate forces and motion.

A wide variety of buggies can be constructed and powered by a jet of air escaping from a balloon. Such a vehicle may run for a distance of 20 to 30 metres...

This resource from Wellcome Trust Sanger Institute is a practical, classroom activity that allows the students to make a balloon model of a disease-causing bacterium. This illustrates its basic shape and structure. Students can choose from three bacteria species...

This resource focusses on making a balloon powered car to learn about forces. Presenting pupils with the question, 'How do things move?' pupils explore aeroplanes and cars, learning about ‘thrust’. Through designing their own balloon-powered car, children will explore how they can increase and decrease thrust,...

A balloon provides a simple example of how a rocket engine works. The air trapped inside the balloon pushes out the open end, causing the balloon to move forward. The force of the air escaping is the “action”; the movement of the balloon forward is the “reaction” predicted by Newton’s Third Law of Motion.

This STEM activity works to develop pupils understanding of how vibrations from sounds travel through a medium to the ear. In this purposeful challenge, pupils will investigate how a balloon can be used as a simple speaker to amplify sound, by blowing up the balloon and listening to how a range of sounds travel...

The Big Picture on pages 10-11 of this issue of Catalyst shows scientists in Antarctica launching a balloon which will travel up through the atmosphere to a height of 34 km above the Earth’s surface. This balloon is part of NASA’s BARREL mission, probing the radiation belts which surround the Earth.

In this activity, students consider the evidence for causal links between sugar consumption, obesity and disease. They then weigh up arguments for and against banning sugary drink sales to children.

Curriculum links include:

Key Stage Three:

*Working Scientifically: Analysis and evaluation –...
