A time-lapse plant growth video lets you see slow changes happen quickly. Plants grow a little each day, but the change can be hard to notice in real time. By taking one photo each day for 14 days, you can turn tiny daily changes into a short movie.
This project helps students practice careful observation, measurement, and storytelling with science.
Key Facts
- Take 1 photo per day for 14 days: total photos = 14.
- Keep the camera in the same spot so changes in the plant are easier to compare.
- Measure plant height each day with the same ruler and the same units.
- Plant growth = final height - starting height.
- Average daily growth = total growth ÷ number of days.
- A time-lapse video plays photos quickly so slow changes look fast.
Vocabulary
- Time-lapse
- A video made from photos taken over time and played quickly to show slow changes.
- Observation
- A careful look at something using your senses or tools to collect information.
- Variable
- A condition in an experiment that can change, such as light, water, or temperature.
- Tripod
- A three-legged stand that holds a camera, phone, or tablet steady.
- Growth
- An increase in size, height, mass, or number of parts in a living thing.
Common Mistakes to Avoid
- Moving the camera each day makes the plant look like it jumps around, which makes real growth harder to see.
- Changing the plant location changes the light and background, so the photos may show a different setup instead of just plant growth.
- Forgetting to label the date can make the photo sequence confusing, because you may not know which image came first.
- Watering randomly can affect the experiment, because plant growth depends on regular care and consistent conditions.
Practice Questions
- 1 A student takes 1 photo each day for 14 days. How many photos will be used in the time-lapse video?
- 2 A plant is 6 cm tall on day 1 and 13 cm tall on day 14. What is the total growth, and what is the average growth per day over 14 days?
- 3 Why is it important to keep the phone or tablet on a tripod in the same position for the whole project?
