Water Rockets

A whole school activity to finish Science Week off - making water rockets. What a blast!!

LIGHT CHALLENGE

 Knowledge attack - Did you know that a ball bouncing off the ground is similar to the way light reflects off objects?

Materials:

• Ball
• Mirrors
• Torch

Procedure:

Part 1 - Outside on a flat surface

With a partner, grab a ball and bounce it between you and your partner. What do you notice about how the ball bounces? Do you notice that the ball is bouncing off the ground in the same angle that it hits the ground at?

Part 2 - Inside

Each student has a mirror

Arrange your students at desks in 2 rows

Give a torch to the students sitting in the first desk

Turn off the lights.

Challenge the teams to adjust their mirrors so that the light from the flashlight reflects off everyone’s mirror on the team and reaches the last person in the row, as shown.

Bubbles!

We looked at how light splits on the surface of a bubble - you can get a rainbow of colours. We also tried to catch bubbles, mould bubbles, mount bubbles, and measure the diameter of a popped bubble. What fun!

MMs and Chromatography

We put 6 different mms on a plate – not touching. Then we added a drop of water on each one – to get colour off each mm. (A tricky process)

While that was happening we prepared our filter paper by sticking it to a stick and putting a starting line on it 2cm up.

Next we used a toothpick to put an extract of colour from mms onto starting line and used the Air to dry colours on paper

We put a bit of water in the bottom of a glass and then place our paper into water

We watched the paper absorb the water and take the colour up the paper

Slime!

Slime

We made green slime. We had a cup each and put water and guar gum in. Then we stirred like crazy. We put a watery borax mixture in and then we stirred like crazy again! Then we put in green dye.

It feels like jelly. It started as a liquid and came out as a solid. I think it is going to melt back into a liquid.

By Hana

We made green slime! It has green bubbles in it.

We put some cold water in a cup and we added some guar gum and stirred it. Then we put some green colour in and it turned dark green. Mrs Brieseman gave us some borax and we stirred it again. It turned solid. When it was sunny it turned very solid.

By Khayne

Here is a link to the slime recipe. We were fortunate to get given the ingredients from a friend of mine trialling science kits but you should be able to get the borax from Lower Hutt Bin Inn and the guar gum from a gluton free store.

ANZAC Writing

Here are 3 examples of our Anzac Writing this week

The Dawn Parade

Why is the Dawn Parade so early in the morning?

The ANZAC Soldiers landed at Gallopoli on the beach at dawn. The soldiers who didn’t die wanted to remember their soldier friends who died. Also, they meet at dawn because it is a quiet time of day.

I think it is good to remember the soldiers.

Poppies

Why do we have lots of poppies?

A poppy grows and scatters many seeds so lots more pppies spread all over the land. The poppies spread all over the fields where the soldiers had been fighting. The soldiers that did not die will remember the people who died in the war because the poppy reminds them

By Ruby

Poppies

Why do we have poppies on ANZAC Day?

Poppies are a flower. They are all over the world. Poppies can be a weed because the seed spreads and grows easily. Poppies grew in the fields where the war happened. They grew where soldiers had died.

We wear poppies on ANZAC Day to remember the people who died.

I think ANZAC Day is a cool day.

Wheels Day

Wheels Day, Fundraising for Vanuatu, and Island dress-ups -What a great way to end the term!

Egg-citing Discovery!

The 'science spot' in Discovery had an Easter theme with eggs - raw eggs!

What we needed was:
A large glass of water
A plastic plate
A cardboard tube (1/3 of a  glad wrap roll but a toilet paper tube would work just as well!)
A raw egg

What we did:
1. Place the plate on top of the glass of water
2. Sit the cardboard tube on top of the plate, lined up directly over the glass
3. Rest the raw egg sideways on the tube
4. Knock the plate out of the way and see what happens!

 

A special thanks to our 'eggs-pert' Damon for the demonstration

What was going on:?:

This is very like the table cloth trick where you pull out the cloth and everything stays on the table. Only this has a higher success rate! 

The plate needed a rim to catch the edge of the tube. The egg is just sitting - not moving. As the support is moved, gravity makes it drop and it lands in the water. (One of Newton's laws of motion) 

Have a 'crack' at this at home- outside!

Happy Easter everyone!
