Seed Germination Experiment
Unidad 1: Los seres vivos y el suelo en que habitan
Tema: Requerimientos y productos de la Fotosíntesis
Objetivo de aprendizaje: (OA1) Explicar, a partir de una investigación experimental, los requerimientos de
agua, dióxido de carbono y energía lumínica para la producción de azúcar y liberación de oxígeno en la
fotosíntesis
Planificar y llevar a cabo investigaciones experimentales y no experimentales de manera independiente
Aim: To investigate the following factors affecting seed germination (water, light and air). Choose one
of the factors affecting seed germination and carry out your experiment.
Materials:
soil
2 transparent plastic containers
6 legume seeds ( beans or lentils)
Stage 1:
* Prepare 2 plastic containers with soil (5 cm) and plant 3 bean seeds in each of them (3cm above the bottom).
* Water them when the soil is dry.
*Check daily until the first sprouts germinate. (The first sign a seed is sprouting is when the seed coat breaks open
and the root pushes out)
Stage 2: IMPORTANT. You can start stage 2 ONLY if your seeds have germinated.
*Measure each sprout and write the info in Day 1 in a chart.
*Label the containers:
*Container 1: control plant (it will get sunlight, water and air)
*Container 2: Choose one of these factors
 (1) no water
 (2) no light. You need a shoe box.
 (3) no air. You need a Ziplock bag.
Instructions:
*Water the “control” container.
*Water the “no air” container. Place it in Ziplock bag and seal it.
*Water the “no light” container. Place it inside the shoe box. No light should be allowed.
*Place the “control”, “no air” and “no water” containers near a window.
Stage 3:
*Check each sprouts every two days, water them when the soil is dry, except the “no water” container.
*Measure the height of the sprouts and record it in a chart. (You can take pictures to see how they are growing)
*Write conclusions about the experiment.
