A Soil Test Experiment

 

Hello Everyone

 

image001

 

As you already know, my two nephews love to do scientific experiments, and this week Miss Pringle their class teacher at the Rocky Bay Primary School set them some homework to do at the weekend again.

 

What they had to do was this:

 

They had to firstly get two jam jars. They put a spoonful of garden soil in one of them and a spoonful of beach sand in the other.

 

They filled both jars three quarters full with water, screwed on the lids tightly, and gave both jars a good shake. Then they left the jars alone over night.

 

ln the morning they rushed downstairs to see what they would find.

 

Do you know what had happened?

 

Well, if you can’t guess l will tell you.

 

The soil had settled into layers with the biggest particles in the bottom layer. The water was a bit of a muddy colour and there were lighter bits floating on the top. These bits are called humus.

 

The sand on the other hand had just sunk to the bottom of the water and was just grains of sand that all looked just the same.

 

Garden soil is much better for growing plants in than beach sand.

 

Only some kinds of plants can grow on a beach.

 

Sometimes gardeners do a similar experiment with the soil in their gardens to see if it is more acid or alkaline. (To give you more of an idea what that means; lemons are acid and bananas are alkaline.)

 

When gardeners do this kind of experiment they have to use a special kind of water called distilled water though; not tap water.

 

Once they know what type of soil they have, they know which type of plants will be happiest growing in their gardens and so then they know which kinds of seeds to plant.

 

lf they have acid soil, they can grow rhododendrons and azaleas and if they have alkaline soil, they can grow lilacs and forsythias.

 

lf they have neutral soil, most things will grow well.

 

This test is called a litmus test.

 

lf gardeners have alkaline soil, this is usually chalky soil, they cannot grow plants like azaleas in their flower beds, but they can plant them in pots using something called ericaceous compost. This compost can be bought in bags. The plants need to be watered with rainwater because the tap water in these areas will have too much chalk in it.

 

After they had written their reports Bill and Bob threw the contents of the jars on the compost heap, washed out the jars and put them in the recycling bin.

 

They really are very good children.

Auntie Alice was working in her large garden this week sweeping up the last of the fallen leaves.  She put them in the leaf store, which is an enormous compound with walls made out of chicken wire, at the bottom of her garden. There they will rot down and become a good soil conditioner to dig into her flower beds next year.

She mows the leaves up off the lawn and when they are cut onto little pieces they will rot down more quickly.

Bill and Bob went to help her and Henry came with them, but it wasn’t long before they had had enough of leaf collecting and their thoughts turned to something else.

As you already know Bill and Bob love climbing trees, and in Auntie Alice’s garden they have plenty to choose from.

Now they’ve got Henry at it!

Be careful Bob, don’t fall again!

HOW TO MAKE POT PLANT HOLDERS

 
If you grow pot plants, they need to be watered regularly and as the water drains out of the holes in the bottom of the flower pot, it needs to be caught in a plant pot holder.

The project this week is a nice idea for recycling.

You can use used supermarket coleslaw and salad pots for smaller plants, but it is a nice idea to decorate them first.

 

image065

 

Put down lots of newspaper first to work on and work in a well-ventilated room.

Use acrylic paint or enamel paint or some sort of paint for plastic or thick water-colour paint mixed with PVA glue.

When the base colour is dry decorate with stickers or cut-out-paper or felt shapes or even your own pictures.

If you get really adventurous, then you could mix up some sand, paint and PVA glue and paint a cheap plastic or clay pot to make it look really expensive. This will create a textured effect on the surface of your pot.

They will look lovely on your window sill.

 

 image066

 

The pot holder in the photograph below was made by painting the pot silver and sticking on a face using wobble eyes and bottle tops.

The ears are washing up bottle tops and the ridged edge of the bottle top used for the nose helps make it look like a part of a machine.

To help the tops to stick to the pot, scrunch some tissue paper up inside the tops first to increase the surface area at the bottom of the bottle top.

If you grow herbs in pot holders with faces on, they will look as though they are growing green hair!

This pot holder is called Rosemary Robot.

You could make her some friends called something like: Percy Parsleyhair, Clive Chivehair and Basil Buckethead. smile1 (2)

Lichens grow close to rocks and other surfaces

Bamboo makes a lovely sound in the wind but can take over a garden if you are not careful

You need to choose the type you buy carefully

and maybe even contain its roots in a large pot sunk into the soil
