Science Activities for Reception: EYFS Ideas and Guides
13 March 2026
Science in the Early Years is all about nurturing children's natural curiosity and encouraging them to ask 'what happens if...?'. From exploring materials in our Three Little Pigs Wind Test to investigating habitats with a Mud Kitchen Bug Hotel, these hands-on activities are designed to make science irresistible for 4–5 year olds. Whether they are melting frozen blocks in an Ice Rescue Mission or observing Play-Dough Life Cycles, you will find plenty of practical ideas to bring the EYFS curriculum to life.
Provides a clear, tangible way to observe germination and the lifecycle of a plant.
Explores changing states of matter (solid to liquid) and temperature.
Introduces invisible forces, magnetism, and material classification.
Hands-on ecology teaching about habitats, minibeasts, and interdependence.
Explores early biology, observing how animals grow and change over time.
Investigating the physical properties of materials and basic structural engineering.
Introduces basic physics, buoyancy, and the scientific method of prediction and testing.
Children explore natural materials, observe mixing, and describe physical properties.
Why Science Matters in Reception
In the EYFS framework, science sits firmly within the Understanding the World area of learning. It is crucial for helping young children make sense of their physical world and their community. By providing rich, play-based scientific experiences, we help children develop key critical thinking skills such as observing, predicting, and problem-solving.
These activities support several key areas and Early Learning Goals (ELGs), particularly within The Natural World:
- Exploring the natural world around them — making observations and drawing pictures of animals and plants.
- Knowing some similarities and differences — comparing the natural world around them with contrasting environments.
- Understanding important processes and changes — exploring states of matter, materials, and the seasons.
Science at this age isn't about memorising facts or getting the 'right' answer; it is about providing a language-rich environment where children can freely explore how and why things work.
How to Use These Activities
The beauty of Early Years science is how easily it weaves into your daily routine. These activities have been carefully chosen to cover a broad spectrum of scientific concepts, ensuring breadth of coverage across your weekly planning:
- Continuous Provision: Set up the Magnetic Loose Parts Sort or the Will It Sink or Swim? tray in your investigation area for independent, child-led exploration.
- Adult-Led Sessions: Use the Play-Dough Life Cycles or the Three Little Pigs Wind Test as focus group activities to guide deeper questioning and introduce new scientific vocabulary.
- Outdoor Learning: Take your class outside to build a Mud Kitchen Bug Hotel or tackle an Ice Rescue Mission on a crisp morning.
Each activity can easily be adapted to suit your current topic, whether you are looking at minibeasts, traditional tales, or seasonal changes. Encourage the children to make predictions, test their ideas, and most importantly, get hands-on!
