Plants come in all shapes, sizes, and colors and are essential for life on Earth. Learn more about how incredible plants are with these hands-on plant experiments and printable plant worksheets. You will find easy plant activities and ideas for elementary to middle school. We love do-able science experiments for kids!


Plant Science

Plant science or botany is a fun topic to teach to kids of all ages. We have a range of plant experiments and projects that would work well in a wide range of settings, from home to the classroom.

Our science activities are designed with you, the parent or teacher, in mind. Easy to set up and quick to do, most activities take only 15 to 30 minutes and are fun. Plus, you don’t need a ton of expensive materials!

Learn about…

  • How living things form part of systems.
  • How energy flows through simple systems.
  • Develop observational skills and practice making predictions.
  • Understand the role of variables in measuring changes.

These plant experiments below are great for elementary to middle school students. For our younger kiddos, check out our list of plant activities for preschoolers.

Plant Facts For Kids

  • Most plants need water, soil, and sunlight to grow.
  • We need plants because they produce oxygen, clean the air we breathe, provide food, they are homes and food for many other living things, and more.
  • Some plants are carnivorous. That means they eat animals (like spiders and insects)!
  • 80% of flowering plants have adaptions so that they can be pollinated by bees and other insects or birds.
  • Some plants do not have flowers or seeds, moss, and ferns. They reproduce by making spores.
  • There are over 390,000 different types of plants in the world. Over 90% of which are flowering plants.
  • Some plants live underwater and are called aquatic plants.
  • About half of all plants are edible. Yet we only eat about 200 plants, and three plants, rice, wheat, and corn, make up over 50% of the plants we eat.

Tips For A Plant Science Project

Science projects are an excellent tool for kids to show what they know about science! Plus, they can be used in various environments, including classrooms, homeschool, and groups.

Kids can take what they have learned about using the scientific method, stating a hypothesis, choosing variables, and analyzing and presenting data.

Our seed germination experiment and plastic bottle greenhouse are both great plant growth experiments to consider for a science project.
