Are genetically modified (GM)
foods okay?

Vocab: genetically modified (GM), crop, benefits, risks, extreme weather, pests, genes

Grammar: should/shouldn't

Warm up: An interactive quiz to engage students and introduce them to the topic.

Real world text: a clip from a video that explains genetic modification in a simple way


Debate: What are the benefits and risks of genetically modifying crops?

Getting to know you!

Do you... ?

What would you... ?

How do
you... ?

Have you
ever... ?

Can you tell
me... ?

What is
your... ?

For example, we can make plants grow bigger or taste better by changing their genes.

GM foods are foods that have been changed by humans, such as scientists like me.

Let's learn more about GM foods.

Hello. I'm Tim, and I'm a scientist. I create genetically modified (GM) foods. Do you know what they are?

Quiz time!

They can grow without sunlight

They don't need soil

They don't need to be cared for

They require less water

They require less water

genes

genetically modiefied (GM)

 when scientists have changed the genes of a plant or animal to make it better or different

good things or advantages that you get from something

possible bad things that might happen

 plants that farmers grow for food, like wheat, corn and rice

very bad weather, like hurricanes, floods or very high temperatures

small animals or insects that can damage plants, like bugs that eat leaves

are tiny parts inside plants that decide how the plant looks and grows

Humans have been genetically modifying plants and animals for thousands of years. Maybe a few of your crops had very good yields. Maybe one of your wolves was especially loyal. So you did the smart thing, and bred the plants and animals that had traits beneficial to you.

yields

bred

beneficial

bred =  have more of

yield =  very high number of something

beneficial =  of benefit, a good thing

 Traits are just an expression of genes. So with each generation, those genes got more pronounced. After thousands of years, almost every single plant and animal around us is vastly different from its pre-domesticated state. If humans have been changing genes for millennia, what makes a so called "Genetically Modified Organism", or GMO, different? 

pre-domesticated

millennia

more pronounced = get stronger

millennia =  thousands of years

pre-domesticated = before humans owned something

more pronounced

generation

generation =  the time it takes for a plant to become an adult, make seeds and die

  Selective breeding is basically hoping for lucky hits. Genetic engineering eliminates this factor. We can choose the traits we want. Make fruit grow bigger, immune to pests, and so on. So, why are people concerned about them ? 

eliminates

immune

concerned

immune =  can fight off

eliminates =  stops

concerned =  worried

Are genetically modified crops
a new thing?

What examples of genetically modified crops did you see in the video?

Do you know of any worries people have about GM foods?

Some people think GM crops might make us sick in the future.

Others don't think it's okay to modify plants' genes and think crops should be left to be natural.

Not everyone thinks GM crops are okay.

What do you think?

Scientists shouldn't
be making GM crops.
It's dangerous!

What do you think?

We should use genetic modification to make crops more healthy.

What do you think?

We should use
genetically modified
crops to help people in countries that don't have enough food.

What are the benefits and risks of genetically modified crops?

Team: benefits

Team: risks

We should genetically modify crops because...

We shouldn't genetically modify crops because...

they are strong against pests

they make enough food to feed lots of people

they reduce the variety of plants
and animals on farms

they have unknown long-term
health effects

 they are expensive

Team: benefits

Team: risks

What are the benefits and risks of genetically modifying crops?

We have a problem! Extreme weather is causing crops to die. Let's create a new GM crop to help!

Create your own GM crop!

What benefits would you like your crop to
have?

Let's chat

Would you eat a GM vegetable that glows in the dark? Why or why not?

If you could make a GM fruit that mixes your two favourite fruits, what would it be and why?

Describe the coolest GM food you can imagine!

Would you prefer to eat natural or GM food? Why?

What would you say to someone who is scared of eating GM food?

Think of your
own question.
