1. Put some damp cotton wool in plastic bags (4 of them) and pour some Crassus seeds on top.
2. Place on the window. When the plants have grown a little, start the experiment.
3. Water the plastic bags with different types of water: one with salt water, one with sugar water, one with vinegar or lemon water and one with plain water. The one dipped in plain water is the control. You can put a frame around the plastic pocket.
4. You can also compare how the cress reacts to boiled water, for example, or water with dishwashing liquid mixed in.
5. Document, compare and discuss.

Idea from Hands-On Science

This is what you need:

• Plastic bags
• Household paper
• Jars
• Flower sprayer
• Potting soil
• Documentation
• Pot
• Drawing material
• iPad
• Stop-motion (app)

Time to collect leftovers from summer flowers. These are called winter standers and are old inflorescences that have dried and are still standing filled with flower seeds. Put the winter stands in bags.

When you get to school/preschool, put the seeds on damp paper towels in different jars and keep the jars warm. For example, in a window with lots of sunlight. After a few days, some seeds will germinate. Then you will see the very first green leaves called heart leaves. Water with a flower sprayer. See how they grow day by day. After a few more days, carefully sprinkle some soil on the seedlings and plant them in a pot.

Option 1:

Rig a recording with an iPad and a stop-motion app that takes a picture of the plant once an hour for a couple of days, and you’ll get an absolutely stunning movie as a result!

Option 2:

What kind of flower will it be? Let the children imagine and draw the flower they think will grow from the seed. These can be beautiful, crazy and imaginative paintings that are perfect for an opening or theme party.

Option 3:

When the spring sun has warmed the ground and it is possible to dig in it. Plant your plants out in the wild again and mark the spot and follow the plant for a year. Document with analogue and digital tools.

How to play?

The worm in the box exercises the ability to divide numbers. The game starts with the teacher and the children investigating how many beads make up the worm’s body. Count the beads in different ways, both backwards and forwards. The teacher takes out the matchbox and tells them that this is the worm’s house. It is important to draw the children’s attention to the number on the house and link it to the number of beads on the worm.  The teacher explains and demonstrates that the worm crawls into the house and hides and then the house closes. Ask the children: how many beads of the worm’s body are inside the house? How do you know? How many are outside the house? Open the house and see how many there are.

What is the purpose of the game?

The purpose of the worm in the box is to practice the ability to divide numbers. It is a concrete and clear way to make addition and subtraction visible to the children. In order to understand the relationship between parts and whole, it is important that the whole is discernible. The worm in the box helps children to practise the ability to automate the division of numbers.

How to make the game?

I have used small matchboxes which I have lined with coloured paper with a number on it. This becomes the worm’s house. I made the worm itself by stringing beads on a thread and tying the ends of the thread. How many beads you need depends on the number you want to practice with the children. My suggestion is to make nine worms with corresponding houses, with numbers two to ten to practice different numbers.

The idea is taken from Mattelekar i förskolan

Take two sheets of newspaper, lay them out flat and start rolling it from one corner. The tighter the roll the more support you’ll have. My boys aren’t tight rolling masters yet but they did pretty well for their first time!

Secure the end with a small piece of tape. An ideal amount would be around 48 but it can be enough with less. Next, you’ll be making triangles with your newspaper rolls. Tape or staple the ends together to form a triangle.

Create as many triangles as you can with your newspaper rolls. Finally, you’ll secure each triangle to each other creating whatever size structure you want!

Your structure size will depend on how many triangles you made. Just make sure you have enough for the roof which will provide the final stability for your fort.  You can secure the “joints” with some extra staples or tape to be sure it doesn’t move around too much.

The rest is up to your imagination! The structure should even be sturdy enough for a blanket on top!
