How to make a model of the Earth

Materials required:

– Blue and green playdough
– Toothpicks and straws
– A balloon or Styrofoam ball
– Paints
– Glue
– Scissors and a cutter

Step 1: Inflate your balloon or Styrofoam ball. Ideally, a Styrofoam ball would be better as it is firmer and won’t deflate. However, if you can’t find one you can use a balloon instead.

Step 2: Cut out a strip from green and blue playdough and stick it around the balloon as shown in the image below. This will represent the Earth’s landmass and oceans. Smooth the edges with your fingers and if you have excess dough, trim it off with a cutter.

Step 3: Get some paints and a brush and paint the Earth’s landmasses green and the oceans blue. You could use acrylic paints or poster colors. Let it dry for about an hour or as per the paint manufacturer’s instructions.

Step 4: Get some toothpicks and straws and cut them to the desired length. These will represent the Earth’s mountains and volcanoes, respectively. Stick the toothpicks randomly around your green dough and the straws in areas you’d like to show off as active or dormant volcanoes.

Step 5: Now get some blue playdough and mold it into a concave shape. This sphere should be slightly smaller than your initial dough. Fit this playdough dome over the landmass you made earlier, this will represent the Earth’s atmosphere.

Step 6: Use a toothpick to add some more details to the Earth’s landmass such as rivers and valleys.

Step 7: Add a thin ring of glue around the circumference where the green dough meets the blue playdough dome. This will make sure your atmosphere stays attached.

And there you have it, your own DIY model of the Earth. It is crucial to note that this model is not to scale and is simply a quick and easy way to make one. However, it still depicts the Earth’s landmasses, oceans, mountains, and volcanoes.

There are other ways to make a model of the Earth too. For instance, one could use papier-mache to create a 3D effect and shape. If you have a printer handy, you could also print out a 3D design that represents the Earth and assemble it using some glue.

Making a model of the Earth doesn’t just have to be a solo project, it can be an excellent bonding activity for families to undertake. Parents could help their kid do this project by guiding them through the steps and letting them have fun with the playdough.

In conclusion, making a model of the Earth is a fun and easy project that can be attempted by anyone with very few materials. It is an excellent way to learn about our planet’s features and could be an excellent educational tool for kids. Get creative and see how you can personalize your Earth model to suit your preferences.
