Science Investigation

We are learning what plants need to survive

We are learning how plants respond to environmental changes.

What do plants need to survive?

Water

Sun

Soil/ fertilizer/ dirt

Oxygen

Carbon dioxide

We are going to conduct a science investigation to determine what will happen to plants when their environment changes. In this assignment we will be changing the environment of each of the mint plants and the potatoes.

What will we need to make this a fair investigation?

• Lots of plants in case one fails
• Make sure they all get the same amount of sun
• Make sure they still have the other things they need to survive
• Monitor progress every few days - with pictures
• Have a “control” plant, that we do all the right things to.

Method:

• Suffocate a plant - by putting it in a container
• Stop watering a plant
• Take out the soil
• Put in the dark
• Normal plant - the control

Hypothesis: I think it will die because it has no soil.

The plant I will be observing is: Taking out the soil.

Observation day 1: It was all healthy on the first day.

Observation day 2: It was droopy and it was getting pale.

Observation day 3: The plant was still droopy and it got more pale.

Observation day 4: The mint plant is turning dead and getting darker.

Observation day 7: Now the mint plant is flat and its dead.

Explanation: Why did this happen to my plant?

The mint plant died because the plant didn’t have any soil and because it needs dirt to help it stay strong.

Maths / 16 - 05 - 16

Sharing Lollies

           We are learning to identify equivalent fractions

Maara and her three friends are going to share a licorice lace. If the lace is 12cm long, what length of the lace will each friend get? What fraction will they get? 1/4

2 other friends approach Maara and would like some of the lace too. How can they split the lace (which has already been cut into quarters) between 6 people equally.

2/12

What would happen if yet another two friends wanted a share?3/24

How many cm of the lace would they recieve?

3/12

Maths Work

We have been learning about fractions and decimals in this term.

Equivalent Fractions!

We are learning to add and subtract fractions with like and unlike denominators.

Levi has ¾ of a bag of lollies. If he is given another 3/12 of a bag, what fraction of a bag will he have? 1 Whole

If there were 32 lollies in the whole bag, how many lollies does Levi have? 32 Lollies

Bob has a 3 3/4 metre of length of wood. He cuts off 2 1/3 metres.

What length of wood is left?

3,9/12 - 2,4/12 = 1,5/12

Nz Zealand Native Tree - Black Fern

Term 1 and Term 2, we have been learning about the Black Fern Tree

Native Bush Trip

On Wednesday 11th of May 2016, The Glenbrae seniors went to

Waitakere Ranges Forest. Here’s what they learnt

•  What we learnt, we learnt that red berries are a sign for birds to come and eat the berries, when they eat the berries, the birds eat the fleshy part and in the middle of it, it will release a hard seed - which comes out after excreting and where it drops new berries will grow.

• We also learnt that a kauri tree can live up to 20 centuries old and it can grow up to 400 metres tall.

• The kauri tree is one of biggest trees in the world. The famous kauri tree is located in the far north of New Zealand. The name of the biggest tree in New Zealand is Tane Mahuta, Tane Mahuta is the god of the forest.

• We learnt that the forest people will take leaves from the tea tree and make tea out of it, most adult men would call their kids to come and climb up and grab the tea leaves .

• We also had the chance to learn about the bird rates. Waitakere birds have gone down because of the pests mostly the possum have eaten the birds and the other things in the forest but now we put traps in the forest and now the possums have died and the bird rates have gone up.

• I learnt that an adult kauri tree can grow up to 400 metre tall. A kauri tree can live for 2000 years. The oldest tree in New Zealand is Tane Mahuta lives up to 1,250 years and it is still standing there until today.

In the end, we all had a good time. Thx for watching

Maths

WE ARE LEARNING TO find fractions of whole and fixed numbers

Today we are participating in a real life problem. Our group will need to work out how to find the fraction of whole and mixed numbers in order to keep everyone happy...

Yesterday we were left with 6 chocolate bars split between 13 children. How much chocolate would each child now receive?

Each person will get 6 / 13chocolate each.

Miss stone doesn’t feel like chocolate today. How much chocolate would each child receive if their are seven chocolate bars.7/13

There were supposed to be 14 children in our group, how much chocolate would each child receive if there were 7 chocolate bars. They will get 7/14

Potato Experiment

Today my class and I are doing experiments on two potatoes. 1 of the potatoes will be put somewhere it has sunlight. The 2 potato is going to be in a dark box and we are going to put a hole in the side of the box. Our experiment is if the potato will grow to the light where the hole is. Below is an example of the experiment we are going to do.


Hypothesis : I think the potato will grow to the light.
