Pre-Activity 0.2PT: Plants Growth Investigation Setup (45-60 min)
Target Student Performance
Students will make initial measurements of the dry mass of radish seeds and growth media and start plants growing.
Resources You Provide
- Small (e.g. 7X10 cm or ramekin) aluminum container (1 per student group)
- 20 radish seeds (1 per student group)
- 15 cm of cotton yarn (1 per student group)
- Brown paper towel (1 roll or 2-3 sheets each student group) Note: brown, unbleached paper towel is required
- Markers/masking tape to label containers (1 per student group)
- A balance to measure masses (1 per student group)
- Large trays with at least 5 cm sides to put the containers in and hold water.(enough for all containers per class)
- Grow lights (highly recommended)
- 1 L of water (for starting seeds)
- 4 L of water with dilute nutrients. (E.g. Ionic Grow, Miracle Grow, etc.) for use once seeds have sprouted.
- Pre-Lesson 0.2PT Plant Growth Investigation Setup Worksheet (1 per student)
- Pre-Lesson 0.2PT Grading the Plant Growth Investigation Setup Worksheet
- Pre-Lesson 0.2PT Plant Growth Investigation Setup PPT
- (Optional) Measuring Plant Growth Video (https://www.youtube.com/watch?v=hVTZMLnhrJQ)
- Things inevitably go wrong when growing plants. Be sure to plant some extras. At least one extra radish plant per group of students is recommended (note that this would double the number of radish seeds you'll want to have available to students).
- Print one copy of the Pre-Lesson 0.2PT Plant Growth Investigation Setup Worksheet for each student.
- Prepare your computer and projector for the Pre-Lesson 0.2PT Plant Growth Investigation Setup PPT.
- Optional: Be ready to view the Measuring Plant Growth Video
There is no assessment for this activity since students are simply setting up an experiment to learn from later on.
- If many of your students seem convinced that plants will not grow without soil nutrients, you may want to grow some radishes in other environments (like clear gel, or a petri dish) to demonstrate otherwise.
- Allow students to take pictures of what they are putting into their containers and as their plants grow as a reference for later on after plant growth.
