2nd Grade Units


	Introduces students to this universal force. Their experimentation confirms that gravity is a constant force. They discover the center of gravity of various objects and learn how this influences balance (Physical Science).	$495.00
	*Science Topics* 1 • The Pull of Gravity – the force of gravity pulls everything down 2 • Gravity is Constant – gravity acts equally on different objects 3 • Center of Gravity – the relationship between gravity and balance 4 • Balancing – how to apply the concepts of gravity

	Allows students to discover the many special properties of water. This includes experimenting with gels, surface tension and water displacement (Physical Science).	$495.00
	*Science Topics* 1 • Water – the many properties of water 2 • Surface Tension – the surface tension of water 3 • Displacement of Water – water cannot be compressed 4 • Attraction of Water Molecules – the attraction of water to itself

	Introduces students to the four factors that affect weather (wind, water, temperature and pressure), including making a Cartesian diver. They use weather instruments and study clouds and storms (Physical & Earth Sciences).	$495.00
	*Science Topics* 1 • What Affects Weather? – wind, water, air pressure and temperature 2 • Weather Instruments – instruments used to forecast the weather 3 • Clouds – cloud formations 4 • Storms – aspects of various storms

	Students discover that the world is round and why we have day and night. Their experiments clearly show why we have different seasons (Earth Science).	$495.00
	*Science Topics* 1 • Day and Night – the rotation of the Earth 2 • The Earth is Round – evidence concerning the shape of the Earth 3 • What Makes a Year – the Earth revolves around the Sun 4 • Why We Have Different Seasons – how the tilt of the Earth makes the seasons change

	Students experiment with wheels, simple machines, flight and the forces that affect motion (Physical Science).	$495.00
	*Science Topics* 1 • Wheels – the role wheels play in transportation 2 • Simple Machines – levers, pulleys and inclined planes and how they work 3 • Forces Which Affect Motion – pressure, air, resistance, friction and inertia 4 • Flight – what keeps planes in the air

	Exposes students to the inhabitants of a pond, using simple microscopes to observe the smaller plants and animals. Throughout the unit, they develop, maintain and study a pond environment in their classroom (Life Science).	$495.00
	*Science Topics* 1 • Looking at a Pond – how to make and use a simple microscope to study pond life 2 • What Lives in a Pond? – the types of plants and animals found in a pond 3 • Tadpole to Frog – growth stages of a frog 4 • Life at a Pond – how to apply their knowledge regarding ponds

	Students learn to identify the main parts of a plant and what plants need to survive and grow. They observe plants as they experiment with photosynthesis and study the life cycle of plants (Physical Science).	$495.00
	*Science Topics* 1 � What is a Flowering Plant? � Plants have distinct parts which have specific functions. 2 � Seeds Grow into Plants � Most plants start as a seed 3 � What Do Plants Need to Grow? � Plants need water and sunlight to grow 4 • The Life Cycle of a Flowering Plant � Plants go through a life cycle

	Students learn to identify the different states of matter and begin to understand different physical and chemical changes (Physical Science).	$495.00
	*Science Topics* 1 • Solid, Liquid and Gas – differences between solids, liquids and gases. 2 • Ice, Water and Steam – the three states of water molecules 3 • Physical Changes – temperature can change the states of matter 4 • Chemical changes – chemical changes can affect the states of matter

	Students learn the basics of nutrition, and what comprises a healthy diet. An understanding of the Food Pyramid and how nutrients are absorbed from food are crucial elements in this unit (Life Science).	$495.00
	*Science Topics* 1 � What is Nutrition? - Students learn to use the Food Pyramid. 2 � Nutrients from Food - Students learn about nutrients from food and how our body uses them. 3 � Where Does Food Go? - Students learn about the digestive system and why food is important to our health. 4 • Exercise Keeps Us Healthy - Students learn that exercise and diet is the best way to maintain health.

	Focuses on the composition of sand and soil and their applications as building materials and environmental regulators (Earth Science).	$495.00
	*Science Topics* 1 � What is Soil - Compare different types of soil and properties of each. 2 � How Does Your Garden Grow? - How properties of soil help affect the growth of plant life. 3 � Does Soil Hold Water - Exploring an important property of soil. 4 • Can We Build It - Soils have different uses based upon their properties.
