The summer term is the perfect time to empower students as they develop their investigative abilities in scientific endeavours. It can provide the opportunity to take learning outside into the warmer weather and the real world for a different style of knowledge and skill acquisition.

You may be looking to select a simple investigation for younger learners or a more complex research-based project for older pupils. This is where a challenging summer science project can come into its own, with countless ideas available to spark children’s scientific interest.

In this article, we share some great summer science project suggestions, alongside some practical tips around organisation, planning and set up. Let the summer science fun begin!

Why summer science projects can inspire

Hands-on STEM learning during the summer months can feel like such a relief after desk-based learning throughout the winter and spring. The practical nature of a science project means that students have to think on their feet, planning for reality rather than the theoretical. 

Additionally, the chance to take scientific enquiry outside the classroom, even if it is just in school grounds, is always guaranteed to lift moods while creating moments for team work and collaboration - all essential skills worth nurturing. 

Plus, science projects that build observational skills, problem solving and analytical opportunities into learning will enhance students’ ability to strengthen their lateral capabilities, enabling them to develop a more open mindset. 

You’ll find a great selection of summer science projects below to try with your classes, both for primary and secondary level. 

There’s even the chance for students to explore summer-related scientific processes happening in their natural environment - ideal for sparking scientific curiosity and creating the next generation of adventurous scientists!

Primary summer science project resources

Sunflower surprise - plant investigation: A great KS1 practical investigation to monitor and observe sunflowers as they grow. This project encourages children to make comparisons, use scientific language and ask questions about plants and seeds.

Light it up: A handy KS2 idea for evaluating, designing and making different torches according to their purpose. An ideal introduction to a new DT project and would make a lovely cross-curricular link with the science topic Electricity. 

Exploring contrasting habitats: Children are asked to consider key aspects of each of the environments and how the animals that live there survive in these habitats - part of an Explorers project.

Bird watching chart: A chart for children to record the birds they see during a bird watching week. Great to use as a homework project in KS1 and KS2. 

Rapid rockets - rocket fuel investigation: A great practical investigation into rockets and finding the best rocket fuel for a fizzy rocket for upper KS2. This project covers the formation of new materials and irreversible reactions. Includes detailed teaching notes for supporting activities. 

Summer solstice: A set of four activities based on the summer solstice in the northern hemisphere. Includes art and craft activities based on Tirol solstice fires, a Swedish flower crown, making a play dough Earth and exploring a text from Shakespeare for solstice references. This resource is suitable for KS2.  

Seasons activities: This set of activities is designed for KS2 learners to explore and understand the different seasons. With a focus on spring, summer, autumn, and winter, there are opportunities to learn about the causes of seasonal changes.

Secondary summer science project ideas

Design a cold pack: This KS3 investigation resource asks students to work in groups to design a cold pack. It would be ideal to use with the KS3 chemical energy topic. Student sheets, teaching notes and instructions are included.

KS3 science activity pack: This activity pack for KS3 science is full of fun science experiments for your lessons, school science club or STEM club. Activities provide insights into the principles behind cutting-edge technologies that can help us to combat climate change. 

How do different cola drinks compare: A practical investigation that is ideal for KS3 classes or would be perfect as a science club activity. There are five stations to set up - full instructions are given - to test fizziness, colour, acidity, sugariness and mass of different cola drinks. 

Crime scene investigation: This KS3 resource involves carrying out a series of practical activities to solve a crime. The mini investigations include testing soil pH, flame tests, chromatography and looking at fingerprints. Students can work in small groups to produce a report of their findings.

Hot rocks - How did cavemen heat water: This KS4 resource can be used as an introduction to specific heat capacity. Students are given different materials that have been heated in a water bath. They put these heated materials into beakers of water to see which raises the temperature the most.

Mystery spillage: Students are asked to suggest how to safely clear up a spillage of an unknown liquid that has appeared on the lab floor. The project presents students with a real-life problem for them to solve using their knowledge of acids, alkalis, neutralisation and lab safety. Teaching notes are included.

Tips for running successful summer science activities

Science projects in primary and secondary settings benefit from some organised planning before carrying them out in the classroom. 

Try these steps to help your summer science project run smoothly:

  • Choose age-appropriate projects.
  • Encourage pupil-led enquiry.
  • Incorporate scientific recording methods.
  • Prioritise safety during practical investigations.
  • Connect projects to the curriculum where appropriate. 

Why summer science projects are a hit with students

A summer science project enables you and your students to celebrate curiosity and discovery in a learning environment. 

It can also help students to maintain enthusiasm for STEM subjects over the summer break, even encouraging them to use everyday objects and environments as powerful learning tools and spaces.
