10 Plant Science Experiments for Kids

10 Plant Science Experiments for Kids post image

We shared ideas of seed science experiments for kids a while ago. Today we will share easy plant science experiments you can do in your backyard or in your kitchen with kids. Kids will love to learn plant biology concepts, such as photosynthesis, transpiration, capillary action, with easy and fun activities.

Easy Hands on Plant Science Experiments for Kids

Plant science experiments for kids learn parts of a plant, function of plant, plant life cycle. Great for outdoor gardening or kitchen science activities projects, school science fair projects, preschool to grade 5. life cycle. nature STEM activity

What do plants need to grow? Why not set up a science experiment to answer the question.

Can a plant survive on orange juice rather than water? Choose two plants of the same kind; two containers, one filled with water, the other with orange juice. Put one plant in each container, observe and record the difference of growth.

Here is another plant growth experiment, but this post explained more in details on how to write hypothesis and how they recorded plant growth data.

To go little deeper in the subject, you can ask how long can different plants survive without sunlight and water? Design an experiment putting plants of different sizes in a black room and don’t water them. But do go check their status daily and record the data. Do you see a difference between the plants of different sizes?

How will plants grow under artificial light compared to nature light? Will you be able to design the experiment yourself?

This is a simple experiment comparing the growth of different plants. You can easily do it in your kitchen.

How plants absorb water? This is an easy but fun experiment young children love.

While the last experiment shows how water travels through the leaves, this one shows how water travels through flowers.

After the last two experiments, you will need this one to explain why plants need water.

How fast does a plant grow? You will find a free printable recording sheet on that post too.

After learning what plants need for growth, try growing sweet potato in your science desk or kitchen science lab. Kids will to see the changes over time and watch the sprouts and roots.

Plant science activities for curious kids, low prep for busy families to learn at home plant life cycle, parts of the plants. STEM activities in the kitchen, backyard.

For older kids, you can create a 3D plant cell, and discuss the difference between plant cells and animal cells.

I hope you like these science experiments. Doing science at home is not just for fun, it is also to cultivate child’s interest in science and help them grow scientific thinking skills. I encourage you follow the scientific steps while working with kids on these fun activities. I outlined the steps and developed this Science Experiment Recording Sheet. I highly recommend using it, even with young children. They can draw pictures if they can’t write. It is the process that is important, starting with questions and hypothesis.

    Thank you so much. I have a 7 year old daughter who was struggling to get inspired for her school science project. I knew she loved nature and searched for nature science experiments, and voila: here you are! There are so many fun and engaging ideas on this page, now the difficulty and choosing one! Thanks.
