How to Build a Simple STEM Ramp for Preschoolers

Preschoolers are natural scientists—they love to test, observe, and ask 'what if?' A simple ramp is one of the best ways to channel that curiosity into early STEM learning. With just a few materials, you can create a hands-on activity that teaches cause and effect, motion, and even basic physics concepts like speed and incline.

In this guide, we’ll show you how to build a simple STEM ramp using the Ramptastic ramp system, a versatile tool designed for early childhood classrooms. You’ll learn how to set it up, run engaging experiments, and extend the activity to keep young learners excited about science.

What You Need to Build Your Ramptastic STEM Ramp

Before you start, gather your materials. The Ramptastic ramp system typically includes track pieces, supports, and connectors, but you can also use cardboard tubes, blocks, or even books to create a ramp. For this activity, you’ll need a few additional items: small toy cars, balls of different sizes, a stopwatch (or a simple timer on a tablet), and masking tape to mark starting points.

If you don’t have Ramptastic, you can improvise with a long piece of cardboard or a wooden plank. The key is to have a smooth, adjustable surface so you can change the incline easily. Having a variety of objects to roll—like a marble, a small ball, and a toy car—will help children compare how different weights and shapes move down the ramp.

• Use a smooth, sturdy surface for your ramp base.
• Choose objects with different weights and sizes for comparison.
• Have a clear, safe area at the bottom of the ramp for objects to roll.

Step-by-Step: Setting Up Your Ramptastic Ramp

Start by setting up the Ramptastic ramp on a flat surface, such as a classroom table or the floor. Connect the track pieces to create a single, straight ramp. If your set includes supports, adjust them to raise one end of the ramp to create an incline. For the first experiment, start with a low incline—about 15 degrees—so children can easily observe the motion.

Once the ramp is set, place a piece of masking tape at the top of the ramp to mark the starting point. Ask children to predict what will happen when they release a car or ball from the top. Then, let them take turns releasing the object and watching it roll down. Encourage them to describe what they see: 'It goes fast!' or 'It rolled straight.'

• Start with a low incline to keep the activity simple and safe.
• Mark the starting point with tape for consistency.
• Let each child have a turn to release the object.

Preschool Velocity Activity: Testing Speed and Incline

Now it’s time to introduce the concept of velocity. Explain to children that velocity is how fast something moves in a certain direction. You can make this tangible by asking, 'Which object will reach the bottom first?' Have children take turns rolling different objects down the ramp and use a stopwatch to time how long each takes to reach the bottom. Record the times on a simple chart.

Next, change the incline by raising the ramp higher. Ask children to predict what will happen: 'Will the car go faster or slower?' Let them test it and compare the times. This simple experiment helps preschoolers understand that steeper ramps make objects go faster—a foundational physics concept. You can also try changing the surface by adding a piece of fabric or sandpaper to the ramp to see how friction affects speed.

• Use a stopwatch or timer to measure how long objects take to reach the bottom.
• Record times on a chart to visualize results.
• Change the incline and compare times to see the effect of slope.

Extending the Activity: More Ramp Experiments for Preschoolers

Once children are comfortable with the basic ramp, you can extend the activity in several ways. Try using different objects like the Kaplan Animal Lacing Boards (though they’re not for rolling, they can be used as obstacles or to create a themed ramp) or the Kaplan Farm Animals Bingo Game pieces as small items to roll? Actually, for rolling, stick to balls and cars, but you can use the lacing boards as side rails or to create a tunnel for the ramp.

Another idea is to create a 'ramp race' where two ramps are set up side by side with different inclines or surfaces. Children can race two cars down each ramp and guess which will win. You can also incorporate art by having children decorate the ramp with tape or markers, or use the Sense of Place Nature's Stripes Carpet to define the landing zone, making the activity more visually engaging.

• Set up two ramps side by side for a race.
• Use different surfaces to explore friction.
• Incorporate classroom items like carpets or posters to create a themed play area.

Building a simple STEM ramp for preschoolers is a rewarding activity that combines play with learning. With Ramptastic and a few everyday items, you can create endless opportunities for children to explore velocity, incline, and cause and effect. Try these simple ramp experiments in your classroom and watch your little scientists thrive.
