Odd One Out

• Furniture group: baby stands out.
• Flowers: boat is the odd item.
• Metals: sand does not belong.
• Solids: sugar is different from salt and copper sulfate.

Separation of Mixtures

• Separation is essential for purity and utility.
• Example uses: washing fruits to remove dirt, filtering water to obtain clarity.

Winnowing

• A process used to separate husk from grains using wind or air.

Separating Pulses

• Use water to rinse pulses, allowing husk and dirt to float and be discarded.

Sieving

• A method of separating solids based on size, often used in flour processing.

Sand and Water Separation

• Utilize filtration or decantation to separate sand settled at the bottom from water.

Sugar and Wheat Flour Separation

• Physical methods such as dissolving sugar in water and filtering can separate components.

Obtaining Clear Water

• Allow muddy water to settle; clear water can be poured off from the top after settling.

Fill in the Blanks for Separation Processes

• The separation method for paddy seeds is called threshing.
• Cream separation from milk involves filtration.
• Salt is obtained through evaporation from seawater.
• The separation method used with muddy water is decantation.

True or False for Separation Methods

• Mixture of milk and water can be separated by filtration. (True)
• Powdered salt and sugar cannot be separated by winnowing. (True)
• Husk separated from grains by handpicking is correct. (True)
• Sieving separates larger particles from smaller. (True)
• Decantation applies in sand and water mixtures. (True)
• Filtration separates insoluble solids from liquids. (True)
• Evaporation can separate solids from liquids. (True)
• A saturated solution cannot dissolve more solute. (True)

Correcting Statements about Plant Parts

• Roots absorb water and minerals from the soil.
• Stem holds the plant upright.
• Roots conduct water to the leaves.
• Number of petals and stamens can vary.
• Joined sepals typically mean petals are also joined.
• Joined petals do not affect the pistil’s attachment.

Drawing Requirements

• Draw a leaf, a taproot, and a flower from the studied material.

Plants with Weak Stems

• Example plant: morning glory, classified under climbers.

Functions of a Stem

• Supports leaves and flowers, conducts nutrients and water.

Leaf Venation

• Reticulate venation is found in: tulsi, China rose.
• Plants with fibrous roots usually have parallel venation in leaves.
