Effervescent canister rockets
Effervescent canister rockets - In this activity, students make a film canister rocket using baking soda and vinegar. They develop their understanding of rocket propulsion and investigate the amount of vinegar that will make the rocket go the highest.
the balloon is attached to an object with plastic parts around it, and then placed on top of each other
Balloon car challenge
In this activity, students design and build a balloon-powered car to better understand the science ideas related to rocket propulsion. They use ideas of mass and force to work out ways to improve the distance travelled by their car.
three different types of pollution are shown in the diagram below, each with an individual's name
Investigating air pollution
Investigating air pollution - In this activity, students investigate exhaust emissions, class car use and air quality.

Investigating UV intensity
Investigating UV intensity - In this activity, students use UV beads to investigate the intensity of UV rays in a range of different situations.
the sun screen application on plastic is shown in four different colors, including orange and yellow
Investigating sunscreens
Investigating sunscreens - In this activity, students use UV beads to investigate the effectiveness of different sunscreen lotions.

Biodegradability experiment
Biodegradability experiment - In this activity, students set up an experiment to determine the biodegradability of different substances. This experiment can be done in groups, with each group given the same or different items from the list below, or each group could be assigned two materials to compare, for example, plastic versus cardboard.
