Democritus believed that atoms were uniform, solid, hard, incompressible, and indestructible and that they moved in infinite numbers through empty space until stopped. Differences in atomic shape and size determined the various properties of matter.
Chadwick felt that the radiation could not be γ rays. The α particles could not provide enough energy to do this. He thought the beryllium rays were neutrons. He bombarded a piece of beryllium in a vacuum chamber with α rays.
Science allows students to explore their world and discover new things. It is also an active subject, containing activities such as hands-on labs and experiments. This makes science well-suited to active younger children. Science is an important part of the foundation for education for all children.
AdaptedMind was created by graduates of Stanford, Berkeley and Harvard to improve the way children learn. We aspire to bring a revolution to education, improving it by pushing the frontier in learning science.
Two-dimensional or 2-D shapes do not have any thickness and can be measured in only two faces. We can classify figures on the basis of the dimensions they have. A circle, triangle, square, rectangle and pentagon are examples of two-dimensional shapes.

“Ecosystem is a complex in which habitat, plants, and animals are considered as one interesting unit, the materials, and energy of one passing in and out of the others” – Woodbury. Organisms and environment are two non-separable factors.
It is mostly used to keep records, calculate probabilities, and provide knowledge. Basically, it helps us understand the world a little bit better through numbers and other quantitative information. Thus, the application of statistics is evident in our everyday activities.
With resources for Pre-K to 8th grade, IXL Math is a good site for practice and drill. While the site also has a paid membership that includes comprehensive coverage of math skills, the free access provides plenty of interactive practice on a variety of skills arranged by age and topic.
Measures are the items in a research study to which the participant responds. Research measures include survey questions, interview questions, or constructed situations. When constructing interviews and surveys, it is important that the questions directly relate to the research questions.
An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts.
