How do plants grow?
Plants need many essential things in order to grow, such as: water, air, nutrients, sunlight, and warm temperature. Plants need their space too! If a plant grows too close to other plants, it may not grow healthy and strong, because the plants may compete over the available water, nutrients, and space in the soil for their roots to grow. Read more...iWorksheets :4Study Guides :1Vocabulary :2
Plant Structure and function
Plants are living organisms made up of cells. Plants need sunlight and water to live and grow healthy. A plant has different parts that are all important in keeping the plant alive and healthy: Roots, Stem, Leaves. A plant’s roots collect water and minerals from soil for the rest of the plant. The main job of a plant’s stem is to carry water and minerals from the roots to the rest of the plant. Read more...iWorksheets :3Study Guides :1Vocabulary :4

Cells, tissues and organs
FreeCells need ENERGY to do all this work. Cellular respiration is the process where cells turn food into usable energy. When similar cells group together and work together for the same purpose, they form tissues. For example, skin tissues protect our bodies from dirt and germs getting inside our bodies. Nerve tissue helps us feel things, such as if something is hot or cold. Read more...iWorksheets :3Study Guides :1Vocabulary :6
Roots, Stems and Leaves
Plants have two different root systems: a Taproot and a Fibrous Root system. Leaves of a plant are made of plant organs and tissues. The top layer of leaf, which protects the leaf, is called its epidermis. Leaves have tiny openings underneath them called the stomata which let air and water in and out of the leaf. Read more...iWorksheets :4Study Guides :1Vocabulary :2
Flowers and seeds
The flower is the seed factory of the plant – where the flower produces seeds. A flower’s sepals cover a developing flower bud in order to protect the bud while it grows. The petals of a flower are often bright and colorful. The stamen is the male part of a flower. The pistil of a flower includes the stigma, style, and ovary. The ovary of a flower contains seeds. The ovule is the part of the plant that becomes a fruit. Read more...iWorksheets :4Study Guides :1Vocabulary :2

Changes on earth
A glacier is a slow moving large body of ice. A volcano is an opening in the Earth’s crust from which hot, melted rock forcefully comes out when pressure is built up inside the Earth. An earthquake is a sudden shift in the Earth’s crust that causes the ground to shake and vibrate violently. Weathering is the process of rocks being changed over time by conditions such as rain, snow, ice, pressure.Read more...iWorksheets :4Study Guides :1Vocabulary :2
