Primary science investigations with plants

A collection of investigations around the topic of plants, looking at life cycles, factors affecting growth, parts of a plant, composting and plants that we eat. Investigations provided by Science & Plants for Schools (SAPS) are:  

Holly leaves: investigate questions about holly leaves.

Tree rings: investigate cut tree trunks to determine the age of the tree, how fast it grew and climatic conditions during its growth.

Investigating if plants grow better with fertiliser: plan and carry out a fair test looking at the effect of fertiliser on growing radishes

The life cycle of a flowering plant: a sequencing activity looking at the lifecycle of Brassica, a fast cycling flowering plant.

How does light affect growing plants?: Plan and carry out a fair test looking at the effect of light on plant growth.

Having fun growing plants: provide the conditions for germination and observe a variety of seeds over time.

Finding out about the number of flower parts: three ways to dissect a flower in order to identify and name the different parts.

Designing a seed: design and make a seed from a newly discovered plant using junk materials.

Are you a plant eater?: Develop an awareness of the parts of a plant that are eaten.

Composting, recycling and the curriculum: investigate what happens during the composting process.
