17) The atmosphere of the earth only has one layer called “the atmosphere”
Activity: 2.1c The rock at Earth’s surface forms a nearly continuous shell around Earth called the lithosphere.
2.1d The majority of the lithosphere is covered by a relatively thin layer of water called the hydrosphere.
Standard: 2.1a Nearly all the atmosphere is confined to a thin shell surrounding Earth. The atmosphere is a mixture of gases, including nitrogen and oxygen with small amounts of water vapor, carbon dioxide, and other trace gases. The atmosphere is stratified into layers, each having distinct properties. Nearly all weather occurs in the lowest layer of the atmosphere.
18) Earthquakes and volcanoes occur in random locations around the world.
Correction: Earthquakes and volcanoes do not occur randomly but on specific limited belts as a result of the plate tectonic forces.
Standard: 2.2a The interior of Earth is hot. Heat flow and movement of material within Earth cause sections of Earth’s crust to move. This may result in earthquakes, volcanic eruption, and the creation of mountains and ocean basins.
Global warming and climate change
19) The greenhouse effect or global warming is caused by something to do with the ozone layer.
Correction: global warming is caused by increased human activities which result to pollution leading to global warming.
Activity: 7.2d Since the Industrial Revolution, human activities have resulted in major pollution of air, water, and soil. Pollution has cumulative ecological effects such as acid rain, global warming, or ozone depletion. The survival of living things on our planet depends on the conservation and protection of Earth’s resources.
20) Man-made activities have little to do with global warming.
Correction: Manmade activities are the major causes of global warming since global warming is brought about by pollution as a result of increased manmade activities.
Activity: 7.2d Since the Industrial Revolution, human activities have resulted in major pollution of air, water, and soil. Pollution has cumulative ecological effects such as acid rain, global warming, or ozone depletion. The survival of living things on our planet depends on the conservation and protection of Earth’s resources.
Standard: 7.2c Overpopulation by any species impacts the environment due to the increased use of resources. Human activities can bring about environmental degradation through resource acquisition, urban growth, land-use decisions, waste disposal, etc.
21) Animals are the only living things. Plants, fungi, eggs and seeds are not living.
Correction: All ling things function through the cellular structure and therefore plant, fungi, and other organisms with cells are all living things.
Standard: 1.1a Living things are composed of cells. Cells provide structure and carry on major functions to sustain life. Cells are usually microscopic in size.
22) Only living things make up an ecosystem.
Correction: An ecosystem consists of both ling and non-living things.
Activity: 6.1a Energy flows from the sun to the ecosystem in one direction through producers, to consumers and then to the decomposers.
6.1c Matter is transferred from one organism to another and between organisms and their physical environment. Water, nitrogen, carbon dioxide, and oxygen are examples of substances cycled between the living and nonliving environment.
6.1b Food webs identify feeding relationships among producers, consumers, and decomposers in an ecosystem.
23) Plants get water through their leaves.
Correction: plants get water through their roots.
Standard: 6.2a Leaves help the plant utilize sunlight through photosynthesis which occurs in plants and other organisms with chlorophyll which is the green coloring matter.
24) Plants obtain their energy directly from the sun.
Correction: Plants, through their leaves absorb light from the sun. This light is then converted to energy in form of sugars.
Activity: 6.2a Photosynthesis is carried on by green plants and other organisms containing chlorophyll. In this process, the Sun’s energy is converted into and stored as chemical energy in the form of a sugar. The quantity of sugar molecules increases in green plants during photosynthesis in the presence of sunlight.
6.2c Green plants are the producers of food which is used directly or indirectly by consumers.
25) Plants produce oxygen for our benefit
Activity: 6.2b The major source of atmospheric oxygen is photosynthesis. Carbon dioxide is removed from the atmosphere and oxygen is released during photosynthesis.
26) Only large land mammals are animals.
Activity: Mammals are not only found on land. There are other mammals found in other habitats.
Standard: Their mode of reproduction is sexual through giving birth or laying of eggs.
27) Whales, jelly fish, and star fish are all fish.
Activity: Fish are in the category of reptiles characterized by their backbone, scales and gills.
Standard: Their reproduction is characterized to be sexual through laying of eggs.
28) Behavior and habitat are criteria for classification.
Correction: Classification is determined by the complexity of the cell structure, body organization, nutrition and lifestyle.
Activity: 1.1b The way in which cells function is similar in all living things. Cells grow and divide, producing more cells. Cells take in nutrients, which they use to provide energy for the work that cells do and to make the materials that a cell or an organism needs. 1.1c Most cells have cell membranes, genetic material, and cytoplasm. Some cells have a cell wall and/or chloroplast. Many cells have a nucleus. 1.1d Some organisms are single cells; others, including humans, are multicellular. 1.1e Cells are organized for more effective functioning in multicellular organisms. Levels of organization for structure and function of a multicellular organism include cells, tissues, organs, and organ systems.
Standard: 1.1h Living things are classified by shared characteristics on the cellular and organism level. In classifying organisms, biologists consider details of internal and external structures. Biological classification systems are arranged from general (kingdom) to specific (species).
