They're tiny and they're teeny, much smaller than a beany! That Atoms Family! The study of atomic structure has to get creative due to the issue of scale - models and research are two ways students can access information about atomic structure. In this lesson, students critically read scientific texts adapted for classroom use to obtain scientific information to describe evidence about the natural world SP8.

In this case, the natural world is made of atoms! So students work to learn the fundamentals of atomic structure in order to access more sophisticated concepts like: Develop models to describe the atomic composition of simple molecules and extended structures MS-PS A basic understanding of atomic structure is fundamental to further study of molecules, chemical reactions and properties of matter.

After students conduct research, they construct scientific explanations based on valid and reliable evidence obtained from their sources SP6. This cross cutting concept also weaves through these related lessons:. Building Atomic Models Simulation Investigation.

This lesson is best used in conjunction with other inquiry-based lessons that use modeling of atomic structure like those above. It can serve as a pre and post assessment or a way to summarize or introduce concepts. This lesson gains "teeth" by using it to support inquiry-based learning.

To help students explore and explain, students access resources to complete the Atoms Family Handout. Hurricane heads harley prompts for the research are on page 2 and their responses are recorded on page 1.

To support students when accessing scientific texts, it is important to find a variety of levels of text with different methods of exploration interactive models, images, etc. Science textbooks include good basic information. Additional online resources that support this research inquiry are:. Chem4Kids Atomic Structure. Science Class Atomic Structure. Nuclear Wallchart Atoms. Teacher Note: This lesson has an artistic component. Once students complete the notes part of the activity on page 1, students cut out the matching rectangular "doors" on page 2.

This cut and staple project adds time to the research, but also helps to blend kinesthetic activity with the mental activity of reading texts and formalizing responses.InDalton put forward a theory which explained the composition of matter. According to Dalton, an atom may be defined as the smallest part of matter that can be take part in a chemical reaction.

Other than hydrogen atom, every atom contains these three subsatomic particles. Structure of hydrogen atom shown that it has only one electron and one proton while the number of neutrons present in it is 0.

The existence of electrons and protons in atoms was first suggested by Sir J. Thomson and Goldstein respectively based on discharge tube experiments and was further confirmed by the phenomenon of radioactivity discovered by Becquerel. The neutron was discovered by James Chadwick by bombarding beryllium with a rays. Matter is any substance which occupies space and has mass. Dalton, inproposed that matter was made up of extremely small, indivisible particles called atoms.

In Greek atom means which cannot be cut. This means that a chemical reaction is just a simple rearrangement of atoms and the same number of atoms must be present before and after the reaction. Atoms of different elements combine in a fixed ratio of small whole numbers to form compound atoms, called molecules.

However, the researches done by various eminent scientists and the discovery of radioactivity have established beyond doubt, that atom was not the smallest indivisible particle but had a complex structure of its own and was made up of still smaller particles like electrons, protons, neutrons etc.

At present about 35 different subatomic particles are known but the three particles namely electron, proton and neutron are regarded as the fundamental particles. We shall now take up the brief study of these fundamental particles. The existence of electrons in atoms was first suggested, by J.

Thomson, as a result of experimental work on the conduction of electricity through gases at low pressures and high voltage, which produces cathode rays consisting of negatively charged particles, named as electrons.

We know that an atom is electrically neutral, if it contains negatively charged electrons it must also contain some positively charged particles. This was confirmed by Goldstein in his discharge tube experiment with perforated cathode. On passing high voltage between the electrodes of a discharge tube it was found that some rays were coming from the side of the anode which passed through the holes in the cathode.

These anode rays canal rays consisted of positively charged particles formed by ionization of gas molecules by the cathode rays. These positively charged particles are called protons. The positive particles are positive residues of the gas left when the gas is ionized. The neutral charge particle, neutron was discovered by James Chadwick by bombarding boron or beryllium with a—particles.

Atoms are made up of three fundamental particles. The charge and mass of these fundamental particles are as follows:. We will gain an in depth knowledge of concepts of atomic structure i.
