Science for Kids | Investigating Contact and Non-contact Forces


Written by Alison Smith

Let’s face it, science for kids is all about hands-on science experiments, investigations, and fun. Science for teachers is quite another story.

Is the thought of planning your next science unit dragging you down like the forces acting on absolutely everything else in the universe?

Hold on to your bunsen burners, our new Push and Pull Science Unit Plan is here!

Science for Kids – Krazy Kristian’s Science Show

Before we take a look at the unit plan, have you been introduced to Krazy Kristian? He certainly knows how to make science for kids fun! Share Krazy Kristian’s Science Show with your class and bring the scientific phenomenon of electrostatic force into your classroom.

This demonstration video has been designed to use in conjunction with our new Push and Pull Unit PlanSo, if you’d like to share this demonstration video, you can find Krazy Kristian’s Science Show on Youtube.

This is the second in our series of science shows from Teach Starter. The first video, called Solid Wood vs Laminate, takes a closer look at the scientific method.

The Ultimate Forces Unit Plan

Because we know how hard it is to plan a comprehensive science unit, we have created the ultimate Push and Pull Unit Plan.  

This Force, Motion, and Energy science unit investigates contact and non-contact forces and what’s more, it is curriculum-aligned. Most importantly, it includes seven fun and engaging lessons plans, science experiments, teaching presentations, and assessment task and all the teaching resources that you need.

Science for kids- Year 4 science unit plan

This science unit is packed to the rafters with time-saving, engaging lesson plans and high-quality teaching resources. The learning objectives of this science unit are to investigate:

  • different types of force
  • the relationship between force and the resulting speed of an object
  • electrostatics and the properties of its associated force
  • magnetism and the properties of its associated force
  • how moving objects in different ways affect the strength of friction force
  • the forces involved in throwing, dropping, bouncing, and rolling, and how they affect an object.

Science for Kids – Teaching Presentations

What makes this unit plan such a brilliant teaching and learning tool? Could it be that the  Push and Pull Unit Plan science unit includes a whopping four teaching presentations!

Kick things off with the Push It – Introducing the Different Types of Force PowerPoint:


During this interactive learning experience, your students will be introduced to the basic concept that a force is a push or pull acting on an object. Then, as a class you will go on to explore:

  • what is a force
  • the laws of motion
  • contact and non-contact forces
  • the force and speed relationship.

Science Experiments Galore!

Science for kids and science experiments go hand in hand. So, the Push and Pull Unit Plan includes three exciting science experiments that your students will love.
Science for kids - science experiment

Students follow the scientific method to conduct these classroom experiments, then complete the science investigation worksheets provided. These science experiments are easy to set up and are sure to be a hit with your budding class of scientists:

  1. Science Experiment – Speed Racer– A science investigation in which the students investigate how to use thrust force to increase the speed of a model car.
  2. There’s a Fraction Too Much Friction – Science Experiment – A science experiment which investigates rolling friction and the properties of various materials and shapes.
  3. Throwing, Dropping, Bouncing, Rolling – Science Experiment – A science experiment which investigates the relationship between multiple forces acting on a single object in various ways.

For more science experiments that your students will love, check out our Science Investigations and Reasoning learning area.

Scientific Method

Don’t forget that a huge part of science for kids is about learning the scientific method. Display and discuss our The Scientific Method Poster – Upper Grades to remind students of the seven essential steps.

Science for kids - teaching Scientific Method

Don’t miss our Scientific Method Word Wall VocabularyDisplay these scientific method word cards around your classroom to immerse your students in this important vocabulary.

Forces Knowledge Check

How do you assess your students’ knowledge and understanding of science concepts? The Push and Pull Unit Plan includes a Forces Knowledge Check that is ideal to use at the end of the science unit or after a science experiment.

Science for kids - assess knowledge and understanding

The worksheets can be used to assess your students’ knowledge and understanding of:

  • contact forces
  • non-contact forces
  • forces in sports and games
  • vocabulary and definitions
  • identification of types of forces.

Just when you thought it couldn’t get any better…an answer sheet has been included with a guide for student answers.
