About this worksheet

What students practice

Students compare habitat conditions with plant needs to predict survival.
Students use evidence to argue why plants would survive well, less well, or not at all in a design.
Students judge plant-display designs using moisture records and plant needs.

How to use

Read the plant needs and design records together. Have students connect each recommendation to evidence before writing their survival argument.

Curriculum

NGSS standard covered

Choose a Living Display for the Kitchen Chalkboard

Compare designs and use evidence to argue which plants could survive.

1. Compare the Display Designs

Read the planning notes and graph. Use the plants' needs to judge the designs.

A Shelf with Room to Grow

A community kitchen has an unused shelf beside its chalkboard. Volunteers want a living plant display there. A plant lamp provides enough light for the three plants they are considering. The shelf stays warm enough for each plant. The volunteers compare three designs before adding plants.

A jade plant grows in soil that drains well. It stores water in thick leaves and does best when its soil dries for several days between waterings. Soil that stays damp for long periods can damage its roots. A Boston fern also grows in soil that drains well, but it needs damp soil most of the time. It can survive brief dry periods, though repeated drying can damage its leaves. Hornwort is a freshwater plant that grows underwater. It takes in what it needs from the surrounding water. It cannot stay alive in a dry pot.

Designs A and B use matching pots with drainage holes and the same soil mix. The volunteers change the watering schedule: they water A twice during ten days and give B small amounts of water more often. At the same time each day, they check whether the soil feels damp or dry. The graph shows their records. Neither pot holds standing water.

Design C is a clear bowl filled with freshwater. Its water level is checked daily so a plant placed inside would stay fully underwater. The volunteers have not tested plants in these designs.
