Science Club: Smoothies and Healthy Eating

Our second science club was all about healthy eating and the children made smoothies.

Smoothie Week

Arrival Craft:

Balanced diet mobiles. 

I drew pictures of dairy foods, fruits and vegetables, meat and fish, and cereals and potatoes. I gave the children some pictures to colour and plates to make simple mobiles.

I gave the younger children one picture from each food group. I gave the older chlidren three pictures from each food group and asked them to sort the pictures into food groups.

The children hung the foods that belonged to the same type together on wool from their paper plates to create a model of a balanced diet (tip: a metal skewer is a really quick and easy way to poke holes in paper plates).

Introduction:

What food groups do we need to eat in order to have a balanced diet? (fruit and veg., meat and fish, dairy, bread and cereals and potatoes, fatty and sugary)

How much fruit should we eat? (UK gov. recommend five portions of fruit and veg. a day, of which a maximum of 1 can be juice, and at least 3 should be veg.)

What is a portion? (for adults 80g fresh or 30g dried; for kids, suggested rule is one handful equals one portion)

Why is fruit good for you? (contains sugar, fibre, vitamins and minerals)

Guess which vitamins each of our fruits contains: stick the vitamins onto the right parts of the body. A (hair and teeth)- Carrot, B1 (heart) – Orange & Pineapple, B2 (growing) – Banana, B5 (digestive system) – Raspberries, B6 (immune system)- Banana & Pineapple, B9 (brain) – Orange, Pineapple & Raspberries, C (bones & teeth) – Orange & Pineapple, E (skin) – Raspberries, K (blood and bones) – Raspberries & Carrots.
Middly helped me draw a picture of a person for this. Then I drew pictures of raspberries, carrots, pineapple, orange and banana on post it notes. As I told the children different parts of the body that these fruits and vegetable were used in, they took it in turns to stick the post its onto the big picture.

Individual Task:

Plan and make your own smoothie.

Bigger children colour fruit pictures, or write words to make their recipe. Here are the recipe sheets for the children to fill in: YourSmoothieRecipe

Biggest children work out the percentages of each fruit in their smoothie to write an accurate recipe.

Gather Together for the Conclusion:

How does your smoothie taste?

Did you look at the fruits as you were mixing them up?

How are they different from each other? (colours, sizes, shapes)

What do all the fruits have in common? (all have seeds, many have skin or rind, all have a fleshy part that can be eaten)

Taste some unusual fruits (just see what we can get hold of); vote on favourites and make a bar chart on the whiteboard.

Break for drink and snack

Optional Extension:

Fruit and parts of fruit colouring sheets.

Cut and stick food pyramids.

Look at a selection of smoothie adverts (I collected catalogues and advertising leaflets to take along, and asked other parents to bring some too) and make an advert for your own smoothie. MakingaPersuasiveSmoothieAdvert
