Today's science lesson is split into two 'experiments' so that you will hopefully be able to do at least one depending on whether you have the right equipment.

Experiment One: What Would Your Age Be On Different Planets?

You will need - some paper, a pen or pencil and a calculator (there's probably one on one of your grown up's mobile phones).

This one works a bit better people older than you so maybe you could use this as an opportunity to phone some people in your family that you're missing - maybe grandma / nanny and grandad? And find out how old they would be if they lived on a different planet.

1. Put your (or someone else's) age into the calculator.

2. Press divide (ask a grown up to show you which button this is).

3. Put in the planet's (you would like to live on) 'period of revolution' (how long it takes to go around the sun) compared to Earth and then press equals (=).

Experiment Two: What Is Your Weight On The Moon?

You will need - bathroom scales and a calculator.

1. Weigh yourself on the scales (try and do it in kilograms - a grown up might have to tell you what you are).

2. Put your weight into the calculator and divide it by six. Then press equals (=). We are dividing by six because the strength of gravity on the Moon is about one sixth of that on Earth.
