(We used boiled eggs instead of raw eggs)
[Grade 3] THAT MAKES SENSE: Exploring the FIVE SENSES
• Exploring the FIVE SENSES •
What’s in the box?
**Students were blindfolded and were asked to pick up an item from the box. They have to touch/ feel and describe the object they have picked and they have to guess what it is.
Loud Sound or Soft Sound?
**Students had to guess which of the items make the loud sound, the soft sound.
Exploring the sense of hearing
Exploring the sense of touch

[Grade 4] Week4: Food Groups
• Looking after ourselves •
• To identify/ classify different food groups:
Healthy (Everyday) Vs. Not Healthy (Sometimes)
Go, Grow, Glow Food
Carbohydrates, Proteins, Fats, Vitamins, Minerals
• Springboard •
Identify the following whether they are “everyday” food or “sometimes” food:
lettuce cheese pizza nuts rice sausages candy apples ham cake
carrots meat pasta milk orange chocolate chicken banana popcorn watermelon
| Go Foods | Grow Foods | Glow Foods |
| > provide you with heat and energy | > help you grow TALL and STRONG | > keeps your body well |
| > rich in carbohydrates, fats | > are rich in protein | > rich in vitamins and minerals |
| starches and sugars | > keep the blood red | > help you maintain good eyesight |
| > make bones, nails and | and healthy skin | |
| Examples: | teeth hard and strong | > keep us from illness/ sickness |
| Rice, bread, pasta, cheese, butter | Examples: | Examples: |
| corn flakes, potato, corn | Chicken, Tuna, eggs, meat, beans | apples, bananas, carrots, lettuce, |
| nuts, tofu, milk and cheese | tomatoes, pineapple, spinach | |
**Carbohydrates give you energy (sugary and starchy foods like: potatoes, rice, cereals, pasta, bread)
**Fats act as the body’s reserve tank of energy, helps our bodies stay warm in cold weather, (dairy products, red meat, poultry, fish and many of the ‘sometimes’ foods)
**Protein helps your body grow and repair itself (meat, poultry, fish, dairy products, eggs and beans
**Minerals help your body grow, develop and be healthy
Iron is good for the blood, Calcium is good for the bones and teeth, Magnesium is good for the nerves (fruits and vegetables)
**Vitamins: vitamin means vital/ essential to life
Vitamin A: Orange and yellow fruits and vegetables (like carrots, sweet potato and pumpkin) and green leafy vegetables, milk and cheese, egg yolk, liver, fish oils
Vitamin D: Tuna, sardines and salmon, Margarines (vitamins added), Milk, butter and cheese, Eggs
Vitamin E: Vegetable oils and some margarine, Nuts and seeds.
Vitamin K: Leafy green vegetables like spinach, broccoli and cabbage, liver.
A
I help you see at night and help your body fight infections
D
I help make strong bones
E
I protect your skin
K
I help stop bleeding

[Grade 5] Week Four: Observation
Objective: To determine which added material will make ice melt the fastest.
This week is observation week, and we will start with “melting”
Review:
∗Solids are often hard and brittle.
∗Liquids are fluid, can move around a little and fill up containers.
∗Gases are always around you.
Today….
We will determine which added material will make the ice cubes melt the fastest.
The changes of state of matter
•When a substance changes from one state or phase to another. (Changes always occur with the change of HEAT.
Today’s Observation:
What makes ICE melt the fastest?
Will a cube of ice melt faster in hot water or in cold water?
Will a cube of ice melt faster in sugar or in salt?
Materials:
ice cubes
transparent cups, bowls
sugar (15ml) + hot water (15ml)
salt (15ml) + hot water (15ml)
hot water (60 ml)
cold water (60 ml)
stopwatch or phone timer
