Science and simulations
Simulations work best when pupils have a question to answer. Before opening a PhET model, give a prediction to test, then ask pupils to change one setting at a time and record what happens.
Free activities to download
Ready-to-run EduTrend Contents free STEM teaching resources workshops for primary, middle and high school. Each free download includes a step-by-step session plan, facilitator notes, three student worksheets and an assessment checklist. Full 20-week programmes are available in EduStore.
Unplugged, Then Scratch
Primary · Ages 7–10
Foundation · 2 × 40 min
Pupils design and perform a dance algorithm unplugged, then recreate it in Scratch, seeing how the idea behind the code comes before the screen.
Consecutive Sums
Primary · Ages 9–11
Developing · 50 min
Pupils investigate which numbers can be made by adding consecutive whole numbers, look for patterns and try to explain the numbers that cannot be made.
Predict, Simulate, Explain
Middle School · Ages 11–14
Intermediate · 60 min
Students use a free science simulation, such as a PhET density model, to test predictions by changing one setting at a time and explaining the results.
Slider Detectives
Middle School · Ages 12–14
Intermediate · 60 min
Students use sliders in a free graphing tool such as Desmos or GeoGebra to discover how m and c change the graph of y = mx + c, then match graphs to equations.
Micro:bit Environment Logger
High School · Ages 15–18
Advanced · 90 min
Students program a BBC micro:bit to record temperature or light levels, collect data around the school, analyse it and evaluate the reliability of the sensor.
