Budding scientists will love learning about the properties of forces and motion by planning and carrying out investigations that explore concepts including friction, speed, and gravity.

Forces make things move -- Slowing down -- Feel the force! -- Let's investigate: Science friction -- Speeding up -- Changing direction -- Let's investigate: Set sail! -- Balanced and unbalanced -- Going up and down -- Patterns of motion -- Let's investigate: in the swing -- Investigate more -- Science challenge tips.
