Fantastic Fact! and just look at how they have to wash their hair!
Hey Aoife this sounds fantastic! Some resources for exploring the night sky
Hi Anna-Rose
This sounds fab! In my experience getting children to create parachutes to protect eggs is a great one (albeit a bit messy). Be careful to express the difference between air resistance and the fact that all objects fall at the same rate. The rate of gravity 9.8 m/s²!
It might be cool to tie this into a history lesson.
This experiment was also demonstrated on the moon during apollo 15 in 1971 where a feather and a hammer fell at the same rate.
Hi Amanda, fab mind map!
Pluto getting reclassified as a dwarf planet is a really interesting one! People often cite it being too small which is only part of the reason! In 2006 the international astronomical union IAU decided to create criteria for planetary status
The body must;
- orbit the sun
- reach hydrostatic equilibrium – basically have enough mass for gravity to cause it to be shaped spherical
- Have cleared the neighborhood around its orbit – this means be able to move other bodies out of its own orbit
Pluto doesn’t meet number three.
Did you know that Pluto has its own moons?

Hi Anna-Rose,
The way in which you have uploaded this is fine! For future reference you can provide an image or a link depending on if you use paper or software. Both icons are on the top right as you write your note or response ! Hope this helps.

Hi Lucy! The age of the GRS is actually contested. Up until 2024 we were certain it was just under 400 years old however a new study might suggest the age of around 190 years old. Here’s a cool article discussing this.
Hi Emma fantastic fact!
We know the main factor determining the shape of celestial bodies is how they spin on their own axis – this explains how the earth slightly bulges at the equator.
Early in the moons life it was closer to the earth and mostly hot liquid surrounded by a thin crust; it was also spinning much faster than it is today. We understand that this is an important chapter in the history of its shape!
Hey Sharon, This is fantastic! some of my favourite space videos involve how water moves on the ISS
Water on the ISS – for Science!
Karen Nyberg Shows How You Wash Hair in SpaceIf you do use the international space station as an example it might be interesting to know that they plan to decommission the space station and deorbit it by 2030!
Hi Doireann, Thank you for your fact. It is quite normal for moons to move around like this in the solar system and beyond. Quite the opposite is happening to one of the moons around Mars – Phobos. This moon will fall closer to the planet and maybe even get ripped apart! https://www.skyatnightmagazine.com/news/mars-tear-phobos-apart-could-happen-sooner

Hi Sharon, That sounds wonderful! What’s cool about choosing a rocket launch site is that we tend to favour sites on the equator, by the ocean and where we can launch rockets eastward!
As we know the earth rotates on its axis (one rotation being a day) but this speed is not the same everywhere – the highest speeds being at the equator this gives rockets an extra ‘push’ when launching.
