We’re preparing for the 2024 Olympics with a enjoyable javelin STEM problem. A javelin is a lightweight spear thrown by hand. In athletics, it’s a discipline occasion the place rivals attempt to throw it so far as attainable.
An amazing javelin throw is a mixture of the thrower’s power and talent and physics! Rivals want to think about a number of elements.
Launch angle – an angle of round 40 levels is regarded as optimum for a javelin throw.
Launch peak – typically, the upper the discharge, the higher.
Javelin pace – the quicker the javelin is shifting when it is launched the additional it is going to journey.
This straightforward STEM problem is a superb introduction to establishing an investigation to be a good check. Kids can select an element to check after which preserve all different variables the identical. We investigated whether or not the size of a javelin affected how far it flew, which meant we needed to attempt to preserve the discharge angle, launch peak and pace of the javelin the identical.
Paper Javelin STEM Problem
We made three completely different sized paper javelins by rolling paper into skinny tubes after which experimented by throwing the ‘javelins’ at completely different angles.
You will want
A4 paper
Scissors
House to throw
Chalk
Tape measure
Tape
Directions
Roll one piece of A4 paper as tightly as attainable and safe with tape.
Use tape to hitch two sheets of A4 paper finish to finish and roll them up.
Use tape to hitch three sheets of A4 paper finish to finish and roll them up.
Throw every javelin 3 times from the identical spot and measure how far every javelin travels. Attempt to preserve the discharge angle and pressure used within the throw the identical.
Document how far every javelin travels to find out which measurement javelin travels the furthest.
Javelin STEM Problem Extension Duties
Experiment by throwing the javelins from completely different launch angles.
