WALKINGRAINBOW
This is a fun experiment to try at home. It demonstrates capillary action, which is how the roots of plants soak up water to drink.
Before you start, you will need 7 glasses, red, blue and yellow food colouring, kitchen roll and water.
Have a look at the video to see the instructions.

Muscles
A couple of weeks ago, you learned about the bones in your body - your skeleton! This week, we're going to explore how our bodies move. To move, we certainly need our bones but we also need muscles. Humans have over 600 muscles! They are attached to our bones and pull on them when we want to move. Here's a quick video to help you visualize.
Now time for a muscular experiment that you can do at home. We learned in school that blood travels all around our body. It brings oxygen and energy to every part of us - from our head, to our fingertips, to our toes. In this experiment, we are going to compare a muscle that is full of blood and energy, to one that isn't getting as much...

I tried this experiment too. My arm that was stretched up got tired so much more quickly. Why is that? Our muscles need good blood supply to give them oxygen and energy.
Finally, here is an activity to use your muscles and to help them relax. Read through the instructions and find a quiet place.

The Skeleton
Here's a song to get you warmed up: The Skeleton Dance!
Our skeleton's are amazing. Adult skeleton are made of 206 bones but children have many more! As children grow, some of their smaller bones join together to make bigger bones. Our skeleton helps to keep us upright and allow us to move. Yes muscles are really important too but when they work, they actually pull our bones around! Our skeleton is also important for protection. Our bones are hard and protect the soft organs inside, like our brain, lungs and heart.
Here's a short video about the human skeleton
Experiment
Calcium is really important for helping our bones grow and stay strong. We get it from things like milk, cheese and other dairy products and also green leafy vegetables such as broccoli and cabbage.
I wonder what would happen if our bones lost their calcium?
