Science

• The three states of matter is solid, liquid and gas.
• the state of matter that has definite shape and volume is solid
• A blood is an example of liquid
• what has definite volume but no shape?

  Liquid
• What is something that can take up space?

  Matter
• what is the quantity of matter in a physical body?

  Mass
• what state of matter is that the particles are very close to each other?

  Solid
• what do plants need to photosynthesize?

  Light, water, and carbon dioxide.
• What do plants produce during photosynthesis ?

  Sugar and Oxygen
• When the amount of carbon dioxide increases, the rate of photosynthesis?

  Increases
• What do the bubbles produced by the plant contain?

  Oxygen
• When more baking Soda is added, did the number of bubbles produced by the plant increases or decreases?

  Increases
• how is the number of bubbles produced by the plant related to the rate of photosynthesis?

  when the number of bubbles produced increases, the rate of photosynthesis increases.
• How does the rate of photosynthesis change when the amount of carbon dioxide increases?

  The rate of photosynthesis increases.
• Plants Trap light in their leaves to carry out photosynthesis
• Glucose made during photosynthesis can be stored as starch in plants.
• Carbon dioxide enters through stomata on the undersides of leaves.
• Photosynthesis takes place in the chloroplasts of green parts of plants such as leaves.
• Chlorophyll absorbs energy from sunlight which is used to make glucose.
• Light energy is absorbed by pigments called chlorophyll which are found in chloroplasts.
• Oxygen produced during photosynthesis diffuses out of leaf through stomata.
• The process of photosynthesis involves carbon dioxide, water and light energy.
• Stomata are tiny pores found on the underside of leaves that allow gases to enter or leave the plant.
• Water from roots moves up into the stem and then into the leaf.
• When the lamp is nearer, the light is brighter.
• When the lamp is further, the light is dimmer
• How did the number of bubbles produced by the plant change when the lamp was placed further from the plant?

  The number of bubbles produced decreased.
• How does the rate of photosynthesis change when the amount of light increases?

  The rate of photosynthesis increases.
• How can the energy in bread be traced back to the sun?

  Photosynthesis
• Plants and animals get their energy directly or indirectly from the sun.
• The energy in food made by plants comes from the sun.
• What do plants produce during photosynthesis ?

  Oxygen and sugar
• Energy has many forms.
• When an object is at a greater height, it has more gravitational potential energy.
• When A toy car is released from a ramp at a greater height, the distance it travels is further.
• What type of energy does the toy car have when it is travelling along the table?

  Kinetic
• How did the height Of the ramp affect the distance travelled by the toy car?

  When the height of the ramp increases, the distance travelled by the toy car increases.
• When the height of the ramp is greater, the toy car on the ramp has more gravitational potential energy. Thus, it travels a further distance.
• Greater mass has more gravitational potential energy.
• When the mass of a ball is greater, it makes a deeper depression.
