Outdoors have always fascinated children and indeed its great to be in open air in many ways too. Coupled with exciting STEM activities for kids, you can easily transform a boring, mundane day into a fun learning experience.

Recent studies indicate how outdoor activities benefit kids, both physically and mentally. These activities provide a great way to practise what kids have learned and to work with their hands – a skill facing constant decline! With the current decline of motor skills, children need outdoors activities more than ever. And what’s more, children always look for an excuse to be outdoors.

So take learning outdoors with this jumbo list of outdoor STEM activities for kids.

Science Outdoor Activities 

1. Sun Prints

This is a wonderful activity to do with little kids. All you need is a sheet of dark coloured paper and a few loose parts like blocks, clay, pebbles etc. These sun prints can later be used for beautiful wrapping sheets and cards.

2. Cola & Mentos Geyser

This is an exhilarating must-do outdoor science activity for kids. Be ready for the boom and the bang!

3. Bursting Bags

This is a quintessential outdoor science activity that every kid must try. It is easy, quick and loads of fun for kids. All you need is a zip bag, baking soda, tissue and vinegar.

Step 1: Take a tissue and put baking soda on it. Fold the tissue neatly to make a baking soda pouch.

Step 2: Pour vinegar in the zip bag and seal the bag just leaving a small pocket big enough to drop in the baking soda pouch.

Step 3: Put the baking soda pouch in the zip bag, seal it quickly and run away.

As the tissue soaks in vinegar, baking soda comes in contact with vinegar resulting in chemical reaction. This reaction produces carbon dioxide -a gas that inflates the zip pouch and forces it to burst.

Sodium bicarbonate + Acetic acid -> Sodium acetate + Carbon dioxide + Water

C2H4O2 + NaHCO3 -> NaC2H3O2 + CO2 +  H2O

4. Evaporation Activity

This is a wonderful activity to delve further into the science of matter. Through this simple activity, your children will learn hands-on how matter changes states and how other factors influence the change in state.

What you will need:

  • 3 containers with varying surface area
  • Water
  • Measuring Cup

Evaporation STEM Activity

Using a measuring cup, pour equal quantity of water in all three dishes and keep them in a sunny spot. Observe the water in the dishes after 3-4 hours. From which vessel did water evaporate the most? Use the measuring cup and measure the water in each dish. Is your hypothesis correct?

5. Soil Science

Children love getting dirty and this is one activity where you will not complain of mud stains! This outdoor science project compares different soils and how the structure of soil in turn affects its flora and fauna.

You will need:

  • Two glass beakers
  • Sand
  • Garden Soil
  • Water
  • Cup

Step 1: Pour sand in one beaker and garden soil in another.

Step 2: Take half a cup of water and pour it in both the sample soils.

Soil science STEM activity

Observe how water penetrates through the different soils. Sand allows faster penetration while garden soil is able to hold on to water. This significantly affects the flora and the resulting fauna in a habitat.

Many such factors contribute to the animal and plant life prevalent in a region. Looking deeper into these factors can help combat the damage caused by human activity and conserve our environment.

6. Bug Viewer

This is one of our all time favourite activities. All you need is a bug viewer and a garden patch. Help your child catch a bug and observe it for a few minutes in the bug viewer. Let them count its legs, spot its eyes and observe its behaviour.

10. Phases of Moon Flip Book

This is one project we seriously adore. All you need to do is click pictures of the moon at the same time, from the same spot for straight 30 days.

Once all your pictures are ready, arrange them in a chronological order. Staple one side and your flip-book is ready!

11. Elephant Toothpaste

This is a classical outdoor science experiment that we strongly recommend be done outdoors. It is messy, foamy and fun!

12. Plant Transpiration

Teach children all about transpiration with this super easy biology experiment. Plants don’t pee like us but then how do they get rid of all that excess water they absorb from the soil? The answer is transpiration.

Plant Transpiration STEM activity

Transpiration is a process through which plants get rid of excess water. But this water loss takes place invisibly! The tiny holes present in plant leaves release this excess water in the form of water vapour, thus making the process imperceptible. But with this clever experiment, you can actually see all the water that plants release back into the atmosphere.

All you need is a zip lock bag and a plant! Simply cover a branch of the chosen plant with the zip pouch and seal it. Observe after few hours. Your kids will be amazed to see water droplets condensing along the sides of the zip pouch, fogging it completely!
