Champion ChallengesHere are Y3-Y6’s Champion Challenges for March 8th to March 12th

Share your learning with your class teacher on J2E, Class Dojo or email.This Champion Challenge focus is SIMPLY SCIENCE because it is British Science Week.

Minecraft Hour of Code

Using Minecraft Education Edition (free from Hwb) complete the Hour of Code 2019 (AI), see video.

Program the Minecraft Agent to collect data about forest fires. Learn coding basics and explore a real-world example

of artificial intelligence.

SALTY SCIENCE - Make your own salt crystals You will need ❋ Warm water

❋ Salt ❋ Large jug or container

❋ Several different shaped and sized small containers ❋ Coloured plastic plate or shallow dish

Put about half a litre of warm water into the jug. Stir in a large spoon of salt until you can no longer see all the grains of salt which means they have dissolved. Keep on stirring in salt, a

spoon at a time, until you reach the point where no more salt will dissolve. Then pour a small amount onto a flat coloured

plate or tray and leave the plate somewhere warm.WHAT DO YOU NOTICE?

Things to talk about … Over the next few days have a close look at what is happening

on the plate. What do you notice? Where do you think the water is going? Can you see the salt again? Does it look the

same as the salt that you started with? What is the same about it? What is different?

Challenge yourself and see if you can make hanging crystals!!

Alfred Russel Wallace

TemperaturesYou can find this activity on a pdf file in the Champion Challenges

folder

Alfred Russel Wallace was a very famous Welsh Scientist. He was an explorer and biologist who was fascinated by

animals and how they lived and survived.

What else can you find out about him and what are his most important Scientific discoveries?

Make a fact sheet about him on J2E5, Adobe Spark, PowerPoint or paper to share what you have found out.

Challenge 1 – Can you write some sentences to explain what you have learnt about the information in the table.

Challenge 2 – Can you use the graph paper to plot a

graph showing the information in the table.

Challenge 3 – Can you create your own temperature chart and graph by finding out the temperature for each day of the week – you could watch the weather report or find out from the internet. You can do this on the graph

paper in the folder or on J2data. Day Temperatur

Grow Your Own Rainbow ExperimentResources you will need:

Paper Towel Felt tips Water 2 small glasses

1. Fold over a piece of paper towel (so you have 2 pieces on top of each other). Trim the length to be 7.5 inches (any longer and the rainbow may not connect fully). TIP: The shorter your piece of paper towel, the better it will connect.2. Draw rectangles of the rainbow colours on each end.3. Place 2 cups with water filled ¾ full. You only want the bottom of the paper towel in so leave some space from the top of the cup.4. The washable marker dye with slowly make it’s way up with the water to meet the other side in the center of the paper towel.5. Leave the paper towel for 10-15 minutes and it will eventually connect the colours together.

Lego Rainbow Challenge

Can you make a rainbow using building bricks?How high is your rainbow going to be?

Is your rainbow going to be sitting on clouds or coming out of the ground?

How many bricks have you used?Have you found a pot of gold at the end of your rainbow?

Design a ParachuteA parachute slows down something that is falling to the ground.

You are going to design parachutes to find out what material makes the best parachute.

You will need:• a ball of plasticine • four pieces of string • different types of

material, e.g. paper towel, writing paper. They all need to be the same size. • stopwatch

How to do it:1. You are going to test one parachute material at a time.

2. Put the four ends of string in the plasticine and press down so they stay in.

3. Tie the other ends of the string to each corner of the parachute material.

4. Hold the parachute up by the material. Each time you do the experiment, you should hold it at the same height.

How to make an Invertebrate Hotel

Can you design and create an Invertebrate Hotel?

What is an invertebrate?

5. Have someone ready to press start on the stopwatch. You might ask a grownup to help with this.

6. When you let go, the person with the stopwatch presses start. They press stop as soon as the parachute hits the ground. 7. Record each time on the British Science Week Parachute

Recording Sheet.

You will need to use resources that you have found both inside and outside.

Have a look at the attached sheet ‘How to make an Invertebrate Hotel’. It includes:

- A list of suggested resources for you to use. - Your instructions. - Key questions to consider throughout the process. - Extension tasks.

Fun Fact- Invertebrates are the most numerous creatures on planet Earth!

The science of a splat!

Your challenge is to investigate water splashes.“Which stone makes the biggest splash? Devise a safe and fair experiment to find out. You will need a bucket, stones and a container of water. Use them wisely!

You will have to decide what you will measure and how you will measure it. Some ideas:

Finding out the mass of each stone. (think about how you could do this)

Deciding the volume of water to be used for each splash.(how will you measure the volume, will you keep it the same for each one – conducting a fair test).

Considering whether the displacement of water by the stone will impact the results. (A scaled jug would be useful in this instance).

Agreeing the height at which each stone should be dropped. (How will you decide on the height and keep it the same for each one).

Measuring the size of the splat. You could chalk around each splat and find out the perimeter of it by using some string to measure it.

You could mark a cross and place the bucket on the cross. The longest length from the cross to the furthest edge of each water splat could then be calculated for

each one.

Think about how you will conduct your experiment and how you will record the results.

How will you measure/ record the splash?

How will you record the weight or mass of the stone, what will you use to find out its weight/ mass?

What do you want to find out?

Think about all of the above and create a simple table to share with your class teacher, you could include pictures of the experiment.
