Learners observe different paper samples under ordinary room light and under a black light to learn some of the chemical differences between different types of paper.

In this four-part activity, learners will discover the exciting world of light--the most important form of energy in our world--and be able to identify and describe different types of light.

In this activity, learners use UV light to transfer a pattern onto a plastic board. The pattern is transferred by placing a mask (a transparency sheet with the pattern) on a plastic board.

In this activity, learners investigate the properties of graphene and graphite.

Learners measure a bottle full of air, and then use a vacuum pump to remove the air. When they re-weigh the bottle, learners find the mass is about 0.8g less.

In this activity, learners investigate the different salinity levels of oceans, rivers and estuaries.

Learners are challenged to create solutions that conduct electricity and make a buzzer buzz (or an LED light up).

In this astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).
