Adaptations are special characteristics of organisms that help them survive in their habitat. Adaptations can be structural, like a polar bear's thick coat of fur, or behavioural, such as how toads hide during the day and come out at night. If an environment changes and becomes unfavorable, organisms must either move to a new habitat or adapt their behaviors and structures to survive, otherwise they will not be able to cope and will eventually die out.
The document discusses using a table of contents (TOC) to help answer science questions involving diagrams, tables, and graphs. It provides examples of how to construct different sections of a TOC, including the manipulated variable, responding variable, fixed variables, aim of the experiment, observations and comparisons, inferences, and operational definitions. Constructing a clear TOC helps convey the key ideas and relationships in a science experiment in a simple, structured way.
Plants have developed various structural and behavioral adaptations to survive in different environments. Structural adaptations include thorns for protection, brightly colored fruits to attract animals for reproduction, and waxy coatings to reduce water loss in dry climates. Behavioral adaptations comprise plants leaning toward sunlight, vines climbing trees, and desert flowers blooming only after rain. Adaptations are seen in plant roots that absorb water and nutrients, leaves that photosynthesize or reduce water loss, and seeds designed for wind or animal dispersal. These adaptations allow plants to thrive in environments like deserts, grasslands, forests, and bodies of water.
This document summarizes a workshop on effectively using clickers in university courses. The workshop covered clicker basics, benefits of clickers, stages of clicker use from simple factual questions to complex conceptual questions, how to write good clicker questions, how to respond to student clicker responses, planning clicker use, and resources for support. Participants practiced writing clicker questions and responding to simulated student answer histograms. The goal was to help instructors think through how to integrate clickers in a way that enhances student learning.

Replication is more than Duplication: Position slides for CHI2011 panel on re...Ed Chi
This document discusses the importance of replication in HCI research, drawing on precedents from experimental psychology. It notes that early HCI research was influenced by experimental psychology's emphasis on establishing the field as a science through rigorous experimentation and replication. The document also describes a 1997 study that compared a hyperbolic and conventional browser but found no overall performance difference, though later analysis revealed individual differences as a better explanation. It argues replication is valuable for exploring more contextual factors and variability in human behavior.
Mathematics has successfully been applied to understand physics, but its application to biology and medicine is still developing. While early attempts at mathematical formalization of biology lacked biological substance, the situation has improved in recent decades. In medical imaging, mathematical approaches can be used to understand image data and make inferences about organs. One promising approach models growth as random iterated diffeomorphisms in biologically meaningful "darcyan coordinates". This allows modeling of growth through discrete cellular decisions over time and derivation of differential equations describing growth in the limit. Further developing the biological basis and applying these methods to real medical data offers opportunities to advance the role of mathematics in understanding biology and medicine.
I. Pattern recognition involves identifying stimuli by recognizing correspondences with stored memories. It allows recognition of variations on patterns and works with incomplete information.
II. Neural network models incorporate top-down and bottom-up processing between word, letter, and feature levels. Top-down signals begin in the frontal cortex while bottom-up signals arise from sensory cortex.
III. Prototype theory proposes that recognition compares input features to stored prototypes, with better category matches seen as more attractive. Facial recognition may involve greater attention to distinguishing features of later-learned racial groups.

This document outlines a natural science unit on reducing casualties from earthquakes and volcanoes. It will cover key concepts like the Earth's internal energy and structure, tectonic plates, earthquakes, volcanoes, and tsunamis. Students will demonstrate their knowledge through exams, activities, and essays. They will learn how density and seismic risk are measured, and how to plot coordinates on a map. The unit aims to develop approaches to learning skills and IB learner profile attributes like being inquirers, thinkers, and risk-takers.
The document provides an overview of statistical analysis concepts through a series of PowerPoint slides. It discusses key terms like the mean, error bars, standard deviation, and T-tests. It explains how to calculate measures like the range and standard deviation. Several slides focus on performing T-tests, including defining the null hypothesis, calculating the critical value and degrees of freedom, and determining whether to accept or reject the null hypothesis based on the test statistic. The document also covers correlations, noting that a correlation does not necessarily indicate causation. Overall, the document reviews important statistical techniques and calculations through worked examples and practice questions.
