Aspects of Secondary Students’ Understanding of Chemistry

The report from the Children’s Learning in Science Project (CLIS) gives an account of a number of aspects of students’ understanding of chemistry including:
*What meanings do students attribute to the terms ‘element’, ‘mixture’ and ‘compound’?
*What meanings do students attribute to commonly used...

Electromagnetic Math

This series of activities from NASA take a mathematical approach to looking at electromagnetic radiation. They are intended as supplementary problems for students looking for additional challenges in mathematics and physical science from age 11 to 19 years. The problems were created to be authentic glimpses of...

Earth Sun Moon Distances

Basketball Earth
This resource uses a basketball as the Earth to set up a scale model to the distance to the Moon, satellites and distances such as the thickness of the atmosphere and the height of transatlantic jets. Students must do a card matching exercise to match objects to...

Earth Math

This series of activities from NASA take a mathematical approach to looking at the Earth and its atmosphere. They are intended as supplementary problems for students looking for additional challenges in mathematics and physical science from age 11 to 19 years.

The problems were created to be authentic...

This collection of three resources asks students to:

*design and model the physical elements of a robot arm and demonstrate how this could be achieved using a smart material. Students can then subsequently use this information to support the design of a robot arm.

*design and model a robot arm in 2D,...

Chromatography of Leaves

In this classic experiment, from the Royal Society of chemistry, students use propanone to separate the pigments in a leaf. Chopping up the leaves, and grinding them up with propanone releases the pigments. Propanone is also the solvent used to separate the pigments. The resource is set out as teachers' notes...

Chlorophyll fluorescence

From Solar Spark, this activity allows students to see how chlorophyll can be energised and how this causes it to fluoresce. Chlorophyll in plant leaves absorb red light and pass the energy on to other parts of the plant, hence leaves look green. But if there is nowhere for the energy to go, it gets released as...

Building a telescope

A classroom activity where students make a simple telescope (using lenses and cardboard tubes)  that uses two different types of lens to magnify distant objects, and then find out how it works.

Bronze Award: Squeaky Clean

These materials look at three possible projects that relate to household cleaning products:

* Communications project - students gather information about cleaning products, compare them and explain how they are suitable for different cleaning problems.

* Practical project - students investigate how...

Bronze Award: Future Travel

 These materials look at three possible projects that relate to sustainable travel.

* Communications project - students gather information and explain about ‘green’ transport policies, reducing and offsetting carbon footprints.

* Practical project - students investigate how to compare carbon dioxide...
