Life cycle of plants 🌱🪴🌷🌼

In the science area we have been learning all about the life cycle of plants.

We  have been noticing lots of dandelions growing in our gardens, so we decided to take a closer look at the dandelion and discover more about the plant.

First we observed the different stages of the plant in our glass box. Some of us  were keen to share what we already knew about dandelions.

“I’ve got dandelions in my garden”

“We can make a wish”

“They grow in the ground”

“They have yellow flowers”

After further discussion, some of us were able to name different parts of the plant.   To develop our knowledge further, we then looked at the petals and seeds up close under the microscope and through the magnifying glass.

“ They are hairy!”

As mini scientists, we have been busy carrying out some different experiments to discover more about the plant.

Experiment 1

We wanted to see if we could change the colour of the dandelions?

We place a few dandelions in different coloured water to see if they would change.
The dandelions remained bright yellow but maybe there are other flowers we could try?

Experiment 2

Are the fluffy dandelions seeds water resistant?

To investigate, we dipped the dandelions seed heads into the water and watched as the seeds repelled the water and puffed back into a ball when gently taken back out the water.
This must help to protect the seeds when it rains.

Experiment 3

Extracting the yellow colour from the petals to make yellow playdough.

We picked a big bunch of dandelion flowers from the garden then picked off the yellow petals and placed them into the pestle and mortar. We ground them a little before placing in a jar with nail varnish remover. After a few shakes of the jar the liquid became yellow. We later added this to our playdough.

“I’ve got tulips in my house”

Experiment 4

We wanted to see if we could change the colour of some white tulips.

We placed a few cut tulips in different coloured water to see if their petals would change. We watched in amazement as the petals in the blue water started to turn blue. As we observed the tulips more we discussed how the flower is having a big drink and absorbs the coloured water, the water travels up the stem and starts to change the colour of the petal.

“They drank the water.”

“Only mine has turned blue.”

Today we have been having a closer look at the tulips. We picked a petal off the flower and trapped it between a piece of plastic to make a slide for the microscope. The colour dye has shown up all the veins in the petals really well. Using the microscope we were able to see the finer details in the petals. 

“It’s got lots of lines”

“ I like the blue one it’s so blue”

We then dissected the flower to discover more. Inside the flower we found the stigma and anther with its pollen. These are all new words for the children.  We talked about how the bee collects the pollen to feed their young and help to pollinate the flowers. We cut up the stems of the flowers that were in coloured water and found that the red and blue colour was all the way up the stem.

”I’m cutting off the stem.”

“It’s sticky and gooey.”

“This looks like blood”

As we chatted away it got the children thinking and asking more questions.

The flowers in the green water did not change colour I wonder why? “Maybe it only drank a little water” or “ maybe because the stem is already green.”

Why did the one in the water not change? “Because it was just in white water”. 

“Where are the bee’s?”

The children have really enjoy taking part in the various experiences in our science area. I wonder were their new found knowledge and interests will lead us to next.

Introducing Cart Mill’s butterfly family 🐛🦋

On the 1st of June our caterpillars arrived at the centre and we have been doing a great job of helping to care for them each day since. We started by investigating the caterpillars 🐛 we watched how they wiggled when they walked and counted how many feet they have; can you believe they have fourteen?!
We watched as they ate their food and got bigger and bigger. They have to shed their exoskeleton in order to grow and we got to feel it, it was very fluffy! Then when we came back after the weekend they had formed their chrysalides! We learned that butterflies come from a chrysalis and it is moths that come from a cocoon.

“They’re so hairy.” “I have caterpillars in my garden.” “Argh, they’re wobbling!”

The chrysalides shook as we transferred them to the butterfly net and we found out that they do this to scare off predators. Next we had to prepare for the butterflies emerging.

“I think they like the nectar.”

When the first butterfly came out from his chrysalis we prepared sugar water for him to drink and put it on some flowers. We also cut juicy oranges and placed them in the net. We learned that butterflies use their feet to taste their food and their mouth is like a curly straw; they unfurl it to drink and then curl it back up again when finished. We now have five butterflies and we have named them Ozar, Mo, Flutter, Anna and Ruby.

“It goes round and round and round.” “I’m colouring my butterfly’s wings.”

After watching the process of the caterpillars changing to butterflies, we were inspired to create our own version of the lifecycle.

Then this morning it was time to let them go….

We started by putting sugar water and oranges on the butterfly table we had previously made with Lauren. Then we opened the butterfly net and waited. And waited 😆 The butterflies were a little hesitant to come out but when they made an appearance they wanted to get up close and personal. One of them landed on the jacket to get a quick cuddle before flying off and the other let us have a turn of holding him.
