Mini-Projects

This series of Mini-Projects, from the Association for Science Education (ASE) aim to breathe life back into investigative work, for students aged 14-16 and their teachers. This resource is part of the SYCD: Science Year Can We; Should we? collection.

The resources were produced by the University of York...

Bright Sparks: Practicals

Six groups of practical activities produced by the Institute of Physics (IOP), for students to explore key concepts of electricity and magnetism.

Accompanied by the Teachers' and technicians' guide for both the practicals and activity sheets. The subjects covered include:- Fuses fantastic, Electric shoes,...

Nappy Changing Challenge

The Nappy Changing Challenge from Cre8ate maths provides real data about students for analysis. They undertake a timed, practical, exercise of folding a towelling nappy and putting it onto a toy baby doll. Throughout the task students complete a form for the Nappy challenge and record their completed data in an...

Fruit Juice Production

Fruit juice companies use a variety of different treatments and enzymes to maximise their yield. In this experiment students will investigate the effectiveness of these different enzymes.

The enzymes used are designed to break down cells walls and release the liquids and sugars which make up the fruit....

Converting Milk Products Using Lactase

The enzyme lactase is widely used in the dairy industry to convert the naturally occurring disaccharide sugar lactose into glucose and galactose. In this practical students investigate the treatment of milk with lactase.

Following treatment they test the glucose content of the converted milk, and compare...

Upgrading Whey

Whey is a waste product from the cheese industry. In this experiment students upgrade whey, by converting the lactose into glucose and galactose, or by growing the microorganism K.lactis on agar containing whey.

Cheese companies are currently developing ways of upgrading the whey so that they can increase...

Fungal Inhibition

In this experiment students grow yeast on agar plates and look at the effect on growth of some common anti-fungal treatments, which are available to treat conditions such athlete's foot and thrush.

Antifungal products may be bought from a local pharmacist, for example, Canistan, Daktarin, Diflucan.

Determining Doubling Time

As the number of cells in a microbial culture increases, turbidity increases. In this experiment students calculate doubling time and growth rate constant using absorbance as the measure of growth.

Turbidity is caused by suspended cells in the growth medium scattering light, and may be measured using a...

Determining Dry Weight

This experiment is a continuation of Determining Doubling Time. Students create a standard curve of absorbance against yeast concentration, and use this to determine the concentration of yeast produced over time.

The standard curve (dry mass, grams per litre) is generated from known concentrations of dried...

Routeway: Solving Constructional Problems

Produced by the Earth Science Teachers' Association, these resources examine how the properties of rocks and local geological features need to be considered when constructing roads.

Students investigate the properties of different building materials before looking at the influence of geology on route...
