Presentation Transcript

Our Learning Garden - Grade 3-Unit 2 Lesson 1-4 Going Green with Green Lentils

  • Lesson Summary- This unit connects children to seeds (green lentils) as they learn about germinating, harvesting, preparing and sharing food. Students explore the anatomy and physiology of seeds in a dynamic PowerPoint presentation that includes many hands on activities. We explore where green lentils are grown and do mapping exercises.

  • Students use required Math skills in the farmer activity- calculating out how many seeds to plant based on germination. The unit culminates with the class creating “The Great Lentil Recipe Book”

  • Our goal is to meet many curriculum outcomes as we introduce the students to a Green Lentils (SUPER FOOD) that is incredibly nutritious

  • All lesson plans and related files for download - ourlearninggarden.ca

The files are open so feel to change content to class requirements.

Grade 3 Kit Contents

  • dry green lentils (available at most supermarkets), bowl, colander and water. Wash /rinse the lentils then soak them in water around 6-10 hours.

  • Some small ziplocs for students to take seeds home, print off the instructions and recipe log book for students -ourlearninggarden.ca

  • Letting the students taste spouted lentils that are added into a soup. Dry soup mix works great is a good introduction for the recipe book activity


Going Green with Green Lentils


Our Learning Garden - Grade 3 Lesson 1 Going Green with Green Lentils

  • Dormancy – The Sleeping Seeds

  • Waking Up the Seed

  • Are Seeds Alive

  • Life Cycles

  • Seeds Anatomy

  • Sprouting (Safe Sprouting)


Wake up that dormant (sleeping) seed.

Do seeds dream?

Cierra, stop dreaming, you have a lesson to teach


  • Seeds are called dormant when they are not growing. Dormant is like sleeping, the seed uses very little energy when it is dormant.




When the seeds wakes up it germinates. Germination is when a seed starts to grow.

  • Seeds start to germinate (wake up) from water

    or Sunlight


The heat from the sun can wake up dormant seeds

The sun heats up the earth.



Inside the Seed

becomes the plant

Is the food for the plant

A seed has its own food supply that it uses called the endosperm


  • When the seed germinates or sprouts the food supply changes so that it is healthier for us to eat

  • The endosperm (food supply) is largest part of the seed

  • The seed uses this food to help it grow when it is very small


Are seeds alive?

  • Sleep (dormant)

  • Dream about ………?

  • Wake up (germinate)

  • Grow when planted


Short Life Cycle


Long Life Cycle

Strawberry plants can live for many years. The runners are a strawberry community that can live as long as 50 years!


Safe Sprouting Practices

  • Soaking: Turning a dormant seed into a nutritional powerhouse. Soak in water 6-10 hours. Remove and drain

  • Draining: It is essential that sprouts be drained thoroughly after rinsing. Use a strainer.

  • Rinsing: Try to rinse 2 or 3 times a day.

  • Air Circulation: If your sprouts can’t breathe while growing they can die. Don’t put them in a closed container.

  • 48 hours or less your sprouts will be ready to eat

  • Cleanliness: Your seed should be clean and your sprouting device should be clean.. Storage: Properly stored, fresh sprouts will keep for up to 1 weeks in your refrigerator but fresher is better. Never refrigerate wet sprouts.


Lets add water to some green lentils and germinate the seeds. Leave the seeds in water for around 6-10 hours


  • The lentils grow bigger as

    they imbibe (drink) the water


Keep the lentils in water for 6-10 hours.

What happens when the lentils are in the water?

IMBIBE or drink the water


Arts & English Assignment

  • Explain in language and drawings why seeds are alive.

    “I wake up when water is splashed on me……………..”


Our Learning Garden - Lesson 2 Going Green with Green Lentils

  • Germination / Sprouting Exercises

  • Learning about Sprouted Green Lentils

  • Bar Graphs and Math

  • Why do farmers need to know the germination rate?

  • Activity-Pretend you are a farmer planting a crop.


After, soaking the seeds, let’s drain and rinse the green lentils


Rinse and wash


Let’s rinse them a few times each day and see what happens


We call the seeds sprouted when the root emerges.

When the seed germinates or sprouts the seed changes so that it is healthier for us to eat


How many seed have sprouted?


Lets count the beans

  • How many lentils have sprouted?

Observe what a sprouted lentil looks like. You can see the root emerging.


  • How many did not sprout?

If no root or sprout emerged (came out),the seed did not germinate (grow).


Sprouting is also called germination

  • Farmers always test their seeds before planting.

  • Gardeners / Farmers need to know the germination rate

  • How many seeds will grow


Gardener Yossi needs to grow 10 corn plants

How many seed will germinate (grow)?

If Yossi wants 10 corn plants but only 1 out of 2 (1/2) seeds germinate.

How many corn seeds would Yossi need to plant in the garden?


Bar Graph

Total seeds 10

Number that germinate 5

Number that do not germinate

Plants you will get 5


Can you make a germination bar graph ?


How many seeds are there?

How many seeds germinated?


ACTIVITY you are a farmer and need 1000 corn plants.

  • You need to have 1000 stalks of corn growing

  • But only ½ or 1 out of 2 corn seeds germinates or grows.

  • How many seeds of corn do you need to plant to get 1000 stalks of corn



On the farm

  • Your farm has 4 acres of land and you need to get 400 stalks of corn.

  • How many seeds do you need to plant if the germination rate is 1 out of 2 seeds (1/2) or 50%?


Lesson 3

  • Understanding why sprouted green lentils are healthy

  • Student Journal Activity and Project

  • “The Great Sprouted Lentil Cookbook”

  • “My Great Sprouted Lentil Recipe Log”

  • Taste Lentils teacher prepares lentils in dry soup mix for students to experience *



Let’s eat some sprouted green lentils


When a seeds sprouts or germinates, the seed usually changes such that is much more nutritious and healthy.

It is easier for your body to get the vitamins and minerals from the sprouted seed.

Increased Bioavailability

Green lentil sprouts contain Vitamins A, B, C and E as well as Calcium, Iron ,Magnesium and Protein: 14%


Sprouted Green Lentils

  • This food is very low in Saturated Fat, Cholesterol and Sodium. It is also a good source of Thiamin, Iron, Phosphorus and Copper Vitamin C, Folate and Manganese.

  • Are sprouted green lentils healthy?


Sprouted Green Lentils


Will you get to try some sprouted lentils in chicken soup?

Make certain your entire family is involved in creating the recipe.

Get all your friends and family to taste it.

Write down the recipe to share with your class.

Then your class can combine all the recipes to make the

Instructions: Soak lentils in water for 10‐12 hours, then drain.

Rinse seeds 2 to 3 times a day until sprouted (2‐3) days).

Sprouted lentils can be stored in the refrigerator for a few days.

Sprouted green lentils contain vitamins A, B, C and E as

well as Calcium, Iron and Magnesium. Protein: 14%

They are very healthy. Great in soup and salads

Lesson 4

  • In the Garden

  • Planting Lentils in the spring

  • Food Security


Sprout some lentils


Sprouted lentils will usually grow when planted in the garden


Record how many seeds you plant.

Observe how many grow into plants


When you harvest your lentil plant; count how many lentils you harvest.

How many seeds did you plant?


Seeds Harvested – Seeds Planted =Yield


Your garden is a healthy fun way to provide your family and community with food.



Growing your own food does not cost very much money. So it has economic benefits. $$$$$


Why is growing your own food good for the environment ?
