Students observe a closed system using a bowl containing some water that is sealed with plastic wrap. They explain their observations and relate their explanations of the water cycle.

In this lesson, students investigate the way different appliances are turned on and off and explore how they can use these functions to save energy.

In this lesson students will explore the way soil and plants contribute to the purification of contaminated water in nature. Students conduct experiments to compare how successful soil and plants are in removing particulates from water by watering plants with contaminated water and assessing the filtered water for turbidity. This activity requires considerable preparation and resources but is simple and effective to run.

Through the use of a flashcard game, students explore some of the reasons why saving energy is important for our environment. They begin to think about what actions they can take to save energy.

Students investigate ecosystem diversity by comparing a variety of ecosystems. They identify the key features and suggest the main factors that influence them. They ask questions about the conservation and threats to ecosystems of interest.

Students compare the structure of a bee and an ant. They discover how these anatomical structures relate to function and help the animal to survive.

In this activity students will explore the processes through which water is made safe for drinking. Students will observe teacher demonstrations around the various processes involved in treating water and will also work in groups to conduct an experiment around one of the stages of water treatment. This activity requires considerable preparation and resources but is simple and effective to run.

In this activity students participate in a test comparing the taste of tap water and bottled water. They then collate and graph data collected and consider the implications of their findings.

In this lesson students are asked to start expressing their views about nature and place. Students will head outside to an area of their school yard. Working in groups, students respond to questions about nature, recording their ideas on separate pieces of paper that the class will then compile to make a flip chart. They then express their personal views through a drawing or a story.

In this lesson students investigate what happens when people’s activities result in water pollution. Pollution on land is simulated with the addition of easily obtained materials in a clear bowl of water. Students make links with retaining healthy waterways with preventing polluting substances from reaching them.

Students make a mini worm farm in a bottle and see exactly how worms move when underground. Through this activity students will understand how worms help to improve soil quality.

Students experiment with creating coolers out of a range of materials, testing to see which materials best keep an ice cube from melting. Through this activity students will understand how insulators can reduce the speed at which items heat up or cool down.

In this activity students will experiment with the surface tension of water using pepper and dish washing liquid. Through this activity students will understand that surface tension can support light materials under specific conditions.

In this activity students create their own ‘lightning’ by watching a spark that travels between a charged surface and a fork. Through this activity students will understand that a variety of sources can be used to generate electricity.

This activity is designed to encourage children to investigate whether objects sink or float in fresh water and salt water. Children will discover that salt water is more dense than fresh water so objects float more easily in it, and they will observe that salt water sinks when added to fresh water. This activity is designed to help connect children to the wonders of the natural world through sensory and play-based learning.

This activity is designed to encourage children to explore how shadows are created. Children will discover that different light sources and different materials can create different kinds of shadows. Older children will also discover that the sun can create shadows of different width and length at different times of the day. This activity is designed to help connect children to the wonders of the natural world through sensory and play-based learning.

In this experiment, students make a rocket using a film canister, an antacid tablet and water. They then explore the variables of the experiment, changing the quantity of each material and observing the impact on the results. Finally, they explore the scientific occurrence and consider whether the reaction is reversible.

This activity is designed to encourage children to observe clouds – their shapes, colours and textures. Children will conduct experiments to create their own clouds on the back of a spoon and will be encouraged to think about how this has occurred. This activity is designed to help connect children to the wonders of the natural world through sensory and play-based learning.

In this experiment, students make a rocket using a film canister, an antacid tablet and water. Through this experiment, students will understand that mixing materials can result in a variety of consequences.

In this activity students get out into an ecosystem and record the sounds that they hear. The sounds can be recorded (e.g. on a tablet), or through drawings or brief explanatory notes.
