Hi everyone, my name is Miss Grove and I'm so excited to be here with you today.

We're going to be looking at the lesson, Being careful with chemicals, and this fits into the unit, Risky substances: How to stay safe at home.

For this lesson, you are required to be with an adult.

So please make sure they are present with you before you press.

Today's lesson outcome is, I can identify dangerous chemicals and items at home.

Let's take a look at our ground rules together and we have some friends here to help us.

Laura says, "We should listen to others." Jacob says, "No judgement !" And that means we shouldn't judge other people based on their stories or experiences that they might share in today's lesson.

Andeep says, "Respect privacy." And that means if someone does tell a story or share their experience, that we don't go and repeat it to other people outside.

And Izzy says, "Choose your level of participation." And that means you can decide whether you want to share something or if you simply just want to listen.

These are today's key words.

I'll read them first to you and then you can repeat after me.

Are you ready? Chemical, battery, poisonous, damage, dangerous.

Great job everyone.

So a chemical is a substance that can change what it touches.

A battery is something we put in electronic things to make them work.

Poisonous is a chemical that can make us very ill if we swallow it or put it on our skin.

Damage, something that causes damage can hurt or injure us.

Dangerous, when something is dangerous, it can cause us harm.

Let's see if we can spot these key words throughout the lesson.

This is today's lesson outline and we are going to begin with why are chemicals dangerous? A chemical is a substance that can change what it touches.

They come in lots of different forms. Here are some examples.

Cleaning spray, vinegar that we might put on our food, and batteries.

Some chemicals are poisonous.

This means they can make us very ill if we swallow them or put them on our skin.

Aisha says, "We must be careful around chemicals to prevent us from hurting ourselves." Well done Aisha.

Some chemicals can damage our skin and some chemicals can damage our eyes.

Check for understanding ,true or false? Chemicals can damage our skin and eyes.

And you can give me a thumbs up if you think it's true or a thumbs down if you think it's false.

True or false? Chemicals can damage our skin and eyes.

Pause this video so you can have some thinking time.

Well done if you said true, chemicals can damage our skin and eyes.

Some chemicals can be liquids, but not all liquids are chemicals.

Here are some examples of liquids that are not chemicals.

Like milk that we drink and honey that eat.

Some chemicals are solids, but not all solids are chemicals.

Here are some examples of solids that are not chemicals like salt that we put in our food and sugar that we eat.

Jacob says, "We can use these in our cooking and they are safe to eat." Some chemicals are gases like this picture here of gas on the stove.

Gases often invisible like air.

The gas from a stove is very dangerous.

It can catch fire and poison us if it leaks out.

Some adults come across chemicals in their jobs.

They use protective clothing to prevent damage to themselves and their bodies.

Like this firefighter, he is wearing gobbles, protective clothes and gloves.

Okay, check for understanding, true or false? Firefighters do not need to wear protective clothing to prevent damage to themselves and their bodies.

You can give me a thumbs up if you think it's true or a thumbs down if you think it's false.

Firefighters do not need to wear protective clothing to prevent damage to themselves and their bodies.

True or false? Pause this video so you can have some thinking time.

Well done if you said false.

Firefighters wear gloves to protect their skin on their hands from chemicals.

Time for a task now.

Label the protective clothing the scientist is wearing.

One example has been done for you.

I spotted that this scientist is wearing a laboratory coat.

Then once you are finished labelling the protected clothing, I want you to explain to your partner why the scientist has to wear protected clothing.

Pause this video so you can complete the task and then we'll go through the answers together.

Okay, well done if you spotted all the things that this scientist is wearing to protect her body.

She is wearing a hairnet to protect her hair, goggles to protect her eyes, a laboratory coat to protect her skin and body and gloves to protect skin on her hands.

Well done.

Now let's see what you could have said to your partner to explain why the scientist has to wear protective clothing.

Your answer could include the scientist is wearing protected clothing because it protects them from dangerous chemicals that can cause damage to their body and skin.

Well done if you said something similar to your partner.

Now let's move on to the second and final part of our lesson.

Which chemicals should I be careful of at home? Sometimes it can be fun making pretend magic potions, but we should never use real chemicals when doing this.

Jacob says, "Using real chemicals is very dangerous because they can cause damage to our body and skin." Some chemicals are safe to use at home.

I wonder if you've spotted any of these chemicals in your house.

For example, washing up liquids to clean your pots and pans, toothpaste to clean your teeth and cooking oil that we can use while we're cooking and making food.

Some chemicals are more dangerous.

We must be careful when using them at home.

For example, cleaning products, gas on a stove, and batteries.

Batteries have chemicals inside.

We can't always see these chemicals.

Some of these chemicals are made from metal.

Batteries can be poisonous.

This means they can make us very ill if we swallow them.

Button batteries can kill us if we swallow them, so we must never put them near or in our mouths.

And here is a picture of a button battery so you know what they look like.

Okay, check for understanding.

True or false? I should be careful when using batteries.

You can give me a thumbs up if you think it's true or a thumbs down if you think it's false.

I should be careful when using batteries.

True or false? Pause this video so you can have some thinking time.

Well done if you said true.

You should be careful when using battery because they are poisonous and could make us very ill if we swallowed them.

Matches are also found in the home.

The head of the match contains two chemicals.

When the head of the match is struck, it creates flame.

Matches can cause dangerous fires and here is a picture of a match with a label that shows you what the match head looks like.

Adults can use matches to light candles or a barbecue.

John says, "Children should never touch matches because they are dangerous." Well done, John.

When we come across dangerous chemicals at home or school, we must find a trusted adult to help us keep safe.

John says, "A trusted adult might be your parents, carer or teacher." Sofia asked, "Can you think of another trusted adult?" Okay, check for understanding.

Who can help me if I come across a dangerous chemical at home or school? a, a friend, b, a teacher, and c, parent or carer.

Who can help me if I come across a dangerous chemical at home or school? Pause this video so you can have some thinking time.

Well done if you said b, teacher, and c, parent or carer.

A trusted adult like teachers, parents and carers can help you if you come across a dangerous chemical at home or school.

Okay, time for a task now.

Sort the words at the bottom of the table into whether they are safe or dangerous chemicals.

One has been done for you and I've put toothpaste in the safe chemical box because I know toothpaste is safe, I use it to brush my teeth.

Pause this video so you have time to do the task and then we will go through the answers together.

Okay, well done for doing the task.

Let's see if your answers are correct.

In the safe chemical box, you should have put toothpaste, washing up liquid and cooking oil.

In the dangerous chemical box, you should have put gas, batteries and cleaning products.

Well done if you sorted out those words correctly.

Okay, so this is the end of our lesson now and I've had a wonderful time with you here today.

Let's take a look at this summary.

So this is all the information that we have covered today.

Some chemicals like cleaning products and gas from a stove are poisonous.

Some chemicals can damage our skin and eyes if we touch them.

Some adults wear protected clothing to protect their body and skin from damage caused by dangerous chemicals.

Matches can start fires that can be very dangerous.

Batteries are dangerous and can kill us if we swallow them.

We should tell a trusted adult if we find chemicals, matches or batteries at home or at school.
