Odd one out
Look at the images and come up with as many similarities and differences as you can. Think about -
Decide which one is the odd one out and why.
Animals need water to survive. Water is found on Earth’s surface in all three states: liquid, solid and gas. Ice and water vapour can both be changed into liquid water. Changes of state are reversible.
We are most familiar with animals that drink liquid water, including the ladybird. Some animals live in extreme environments where it is too hot or too cold to find liquid water on the surface. Some of these animals have adaptations (special features or behaviours) that help them change ice or water vapour into liquid water that they can drink.
Choose one of the animals to research and find out about how they have adapted to help them change ice or water vapour into liquid water that they can drink.
How does exercising at different intensities affect heart rate? Collect a stopwatch (you might have one on a phone), paper and pen and head outside into your garden.
First you need to find your resting heart rate. To do this, spend five minutes or so relaxing and being inactive. Use this time to practice finding your pulse.
Now, record your resting heart rate. To do this, record your pulse over 15 seconds. Multiplying this number by four will give your resting heart rate (beats per minute).
Now, spend 30 seconds exercising at a low intensity (e.g. walking). At the end of the 30 second period, immediately record your pulse rate over 15 seconds and calculate the heart rate (beats per minute). Repeat this process at two further intensity levels (e.g. jogging and sprinting). In between the bouts of exercise, ensure that you rest and your heart rate has time to return to its resting rate.
You should now have four sets of data: Resting heart rate and your heart rate after three different exercise intensity levels.
Is there a relationship between the intensity of exercise and heart rate? Have a discussion – can you explain your findings using what you know about how the human body works?
If you are able to, help your parents with the cooking or do some baking. Look at how the ingredients change when cooking. Changes to ingredients when baking cakes or cookies in the oven are permanent changes. What permanent changes can you spot? Are there any changes in the kitchen that are not permanent?
Earth and Space
What if there was no moon?
The Moon's size (compared to other moons in the solar system) means its presence has a steadying effect on Earth's rotational angle or tilt, keeping it inclined at around 22 degrees.
With no Moon, the Earth would 'wobble', resulting in more dramatic seasons and weather. The Moon is also responsible for the tides, as well as being used by many animals as a navigation aid.

Earth and space
Consider the perils of space while designing your own space suits!
As you follow the mission, think about these prompts...
Create a space suit design. Think about the things a space suit might have to go through or be used for and the materials that would be best to survive the conditions.
A spacesuit is more than just clothes that astronauts wear in space. Think of it like a really small spacecraft! It protects the astronaut from the dangers of being outside in space as it is very different from being on Earth. They need to stop the astronaut from getting too hot or cold. The suits also need to give them oxygen to breathe and water to drink. They need to protect them from space dust that can travel faster than a bullet! They have gold-lined visors to protect them from bright sunlight and play a critical role in any space mission.
