Happy World Earth Day

Today is the ideal day to be thinking of ways that they could care for the planet.  Children at Titchmarsh Church Of England Primary School have been thinking of ways to care and protect our environment and all living things.

Little Larvae

Meet Primrose, Snowdrop, Tulip, Daffodil and Emily!  5 healthy larvae recently hatched from their tiny eggs for the first stage of their very interesting life cycle.  Imagine being able to crawl on land then fly away.  The eco team and year 2 are very excited to study the different phases carefully.

Family Fun in the Garden!

A massive thanks to all who gave their all to help clear and spruce up the school gardens today.  The work achieved was beyond our wildest dreams.  Trees were pruned, the shed emptied out and spring cleaned, the large propagator is rejuvenated with trays of sown seeds, the old pergola was removed, pots were replanted, hanging baskets restored, carrots sown for pet rabbits, the African keyhole garden space created, 2 tonnes of soil was removed and bagged up for Year 5’s garden (African Garden) event next term, bricks relocated, the list goes on… whew!

We look forward to welcoming the summer gardening team to our new look space!

What Do Plants Need To Be Healthy? Year 2 Investigate…

Year 2 have enjoyed investigating the conditions required for seed germination and healthy growth.  The results are shown above and below and really surprised us all.  We discovered that the mustard seeds grown without cotton wool under 24 hours light in the light bank did not germinate but the cress seeds under the same conditions on the window sill did germinate and grow quite well despite no growing medium!

Does this mean too much light prevents germination or was it due to the type of seed making a difference?  How long can the plants grow without any growing medium?  We will repeat this again using the same type of seed to find out more!

Magnified seeds that germinated in a petri dish without any cotton wool.  They had very stunted stems and very long roots!  Were they searching for something to hold onto?

We also discovered that the seedlings grown in the dark grew twice the height of those in daylight and were yellow.  We think this teaches us that there is a lot of energy stored in the seed to get plants off to a good start and they are willing to invest it all in growth in their search for light.  We are wondering how long they can grow without light and what will happen if they don’t get any.

The leaves were yellow and stems 5 times taller than those in the light!

 

The magnified seeds that were grown in the dark.  Tall thin stems searching for the light.  Scientists call this etiolation, a process in flowering plants grown in partial or complete absence of light.

 

The plants grown under our light bank were far more advanced than those grown on the window sill.  We couldn’t believe the difference in the height of the beans, some were 10 times taller.. This does prove to us that the amount of light really does matter and that growth and plant development can be accelerated by it.  Following on from our experiments we have been learning more in books and have been finding out that plants use Photosynthesis which is the process where plants use the energy from the sunlight (or light bank) to produce glucose which they will use as their source of energy to grow.  For this they need carbon dioxide which they take in through their leaves and water which they absorb through their roots.  Some bacteria can also use this amazing process of photosynthesis too.

Willow Class Seed Investigation – What do seeds need to germinate and grow into healthy plants?  They researched the effect of light, heat and growing medium (cotton wool).
