EdPlace's 5-a-day for home learning

Hey super-star! Looking for National Curriculum aligned short lessons to keep your child engaged and learning? We've got you covered. Our experienced team of teachers have created English, maths, science and 11+ lessons so your child can learn and hone their key skills no matter where they are.

Get them started on the lesson below and then jump into our teacher created activities to practice what they've learnt. We've recommended 5 to ensure they feel secure in their knowledge - 5-a-day helps keeps the learning loss at bay (or so we think!).

All activities are created by teachers and automatically marked. Plus, with an EdPlace subscription, we can automatically progress your child at a level that's right for them. Sending you progress reports along the way so you can track and measure progress, together - brilliant! 

Are you keen to start practising straight away? Head to the bottom of the page to find the activities. 

Now...onto the lesson!

Year 7 statutory requirements - The variation between individuals within a species being continuous or discontinuous, to include measurement and graphical representation of variation

 

Our learning objective

Every good lesson has a purpose or an objective. We’re confident by the end of this that your child will be able to identify different variations. They’ll be able to apply their knowledge and if they’ve really cracked it, they should be able to compare the different types of variations.

 

Step 1: Let's learn

Before we jump into identifying the types of variations it’s important to check that your child understands what the key terminology means.

A variation is simply the differences between organisms either of the same species or different species. Humans belong to the same species yet there’s lots of ways we are different. Some people may have brown coloured eyes whilst others have blue eyes; this is an example of a variation.

Inherited or genetic variation is a feature that has been passed on from your parents, something that’s in your genes, so for example the brown hair that you’ve got from your mum.

Other characteristics are due to a person’s surroundings or environment. For example, a scar on your arm from when you fell over as a child. You don’t inherit these.

Children vary a lot. Some may be really tall for their age, others may have really large feet, these variations can be measured (literally, with a ruler maybe or meter stick) and are called continuous variations. 

Other variations can’t be measured, for example one child may be able to roll their tongue while the other can’t. There isn’t an in-between, (you can’t half roll your tongue!) so we call this a discontinuous variation. When you think of the word discontinuous think of discrete or distinct (as in distinct categories).
 

Step 4: Let's have a go

Why not apply your knowledge to the following questions?

Identify whether each variation is continuous or discontinuous.

  1. Natural eye colour

  2. Length of hair

  3. Having a cold

Compare the following variations and state why they are different:

  1. Shoe size and foot length

  2. Having a tattoo and length of arm

 

Answers:

  1. Discontinuous variation

  2. Continuous variation

  3. Discontinuous variation

  4. Shoe size is an example of discontinuous variation whereas foot length is continuous variation. This is because shoe sizes are distinct categories and aren’t measured (a bit of a trick question, as you can be a shoe size 5 or 5½ but you can’t be a shoe size of 5¼!) whereas foot length is continuous variation as it can be measured from a range of values (for example 21.6cm).

  5. A tattoo is discontinuous as it’s a distinct category and length of arm is continuous as it’s a measurement.

 

Step 5: Let's apply your knowledge

Now, you’ve covered this together why not put this to the test and assign your child the following 5 activities in the following order.

All activities are created by teachers and automatically marked. Plus, with an EdPlace subscription, we can automatically progress your child at a level that's right for them. Sending you progress reports along the way so you can track and measure progress, together - brilliant! 

Activity 1 - Fertilisation

Activity 2 - Variation

Activity 3 - Sorting Organisms

Activity 4 - Classification 

Activity 5 = Environmental Variation
