Have you ever mixed things together just to see what happens? It’s like making magic potions, but it’s actually science! Let’s explore some fun mixtures and learn about them.
For our first experiment, you’ll need a clear container, a spoon, some water, and play sand. Fill the container with water and add a spoonful of sand. Stir it around and watch what happens. At first, the sand floats around, but when you stop stirring, it settles at the bottom. This is called a suspension. In a suspension, the ingredients can be separated after mixing. You can even use a filter to separate the sand from the water!
Next, let’s make a different kind of potion. Use water again, but this time add sugar instead of sand. Stir it well. The sugar seems to disappear, but if you taste the water, it’s sweet! This is a solution. In a solution, the ingredients mix evenly and can’t be separated, even if you let it sit for a long time.
Let’s try another experiment. Pour water into a jar and add a few drops of food coloring. Shake it up. The coloring mixes evenly and doesn’t settle, making it a solution. Now, add some oil to the jar and shake it again. The oil forms globs and separates from the water, creating a suspension.
Now you know about two types of mixtures: suspensions, where ingredients can separate, and solutions, where they mix evenly and can’t be separated. Keep experimenting and see what cool potions you can create!
Have you ever wondered why Swiss cheese has holes? It’s not because of mice! The holes, called “eyes,” are made by bacteria. When bacteria eat the milk, they create bubbles that form holes when they pop. Modern cheese-making methods have fewer holes because there’s less hay in the milk, which used to help form the bubbles.
Flowers are not just pretty; they have an important job. They attract animals like bees and butterflies, which help spread pollen. This process, called pollination, helps flowers make seeds for new plants. Each part of the flower, from the stem to the petals, plays a role in attracting pollinators.
Did you know that Saturn is not a star but a planet with beautiful rings? Saturn is much bigger than Earth and has 62 moons. Its rings are made of rock and ice, moving in orbit around the planet. Scientists think the rings might have formed from moons that broke apart long ago.
Dinosaurs may seem like creatures from the past, but some of them survived and evolved into birds! Birds are descendants of theropod dinosaurs, which had bird-like traits like feathers. So, when you see a bird, you’re actually looking at a living dinosaur!

Suspension and Solution Hunt: Go on a hunt around your home to find examples of suspensions and solutions. Look in the kitchen, bathroom, or even outside. Can you find a suspension like muddy water or a solution like saltwater? Try to describe what you see and explain why it is a suspension or a solution.
Create Your Own Potion: With the help of an adult, gather some safe ingredients like water, oil, sugar, and food coloring. Try mixing them in different ways to create your own potions. Can you make a suspension or a solution? Write down what you used and what happened. Share your potion with a friend or family member and explain what type of mixture it is.
Question Time: Think about these questions and discuss them with a friend or family member:
