Ten simple rules for providing a meaningful research experience to high school students
There are many formal opportunities for high school students to conduct research, but early-career scientists and principal investigators (PIs) do not necessarily have much experience working with this age group, which presents different opportunities and challenges than working with undergraduates. [...]we present guidance in this Ten Simple Rules article on how to be an effective research mentor for high school students based on our experiences as early-career biologists and our formal mentor training. Some universities and medical schools have volunteer offices or organized programs for bringing high school students into the laboratory, so check whether there are already connections to schools in your area through previous student placements. [...]when initiating contact with prospective mentees, consider the opportunity you have to make a meaningful impact in the lives of young people who come from historically underrepresented and underserved populations or underprivileged backgrounds. Set goals early, and revisit them often The student might have unrealistic expectations of what they can accomplish during their research experience because they are new to laboratory research. [...]it is your duty as the mentor to explicitly set goals with both the best- and worst-case scenarios in mind and to manage expectations. [...]to put everything on paper, consider developing a document in collaboration with the student that outlines expectations for communication and goals for your time together [14].

Demand Effects in Survey Experiments: An Empirical Assessment
Survey experiments are ubiquitous in social science. A frequent critique is that positive results in these studies stem from experimenter demand effects (EDEs)—bias that occurs when participants infer the purpose of an experiment and respond so as to help confirm a researcher’s hypothesis. We argue that online survey experiments have several features that make them robust to EDEs, and test for their presence in studies that involve over 12,000 participants and replicate five experimental designs touching on all empirical political science subfields. We randomly assign participants information about experimenter intent and show that providing this information does not alter the treatment effects in these experiments. Even financial incentives to respond in line with researcher expectations fail to consistently induce demand effects. Research participants exhibit a limited ability to adjust their behavior to align with researcher expectations, a finding with important implications for the design and interpretation of survey experiments.

The Ultimate Book of Saturday Science
The Ultimate Book of Saturday Scienceis Neil Downie's biggest and most astounding compendium yet of science experiments you can do in your own kitchen or backyard using common household items. It may be the only book that encourages hands-on science learning through the use of high-velocity, air-driven carrots.
Downie, the undisputed maestro of Saturday science, here reveals important principles in physics, engineering, and chemistry through such marvels as the Helevator--a contraption that's half helicopter, half elevator--and the Rocket Railroad, which pumps propellant up from its own track. The Riddle of the Sands demonstrates why some granular materials form steep cones when poured while others collapse in an avalanche. The Sunbeam Exploder creates a combustible delivery system out of sunlight, while the Red Hot Memory experiment shows you how to store data as heat. Want to learn to tell time using a knife and some butter? There's a whole section devoted to exotic clocks and oscillators that teaches you how.
The Ultimate Book of Saturday Sciencefeatures more than seventy fun and astonishing experiments that range in difficulty from simple to more challenging. All of them are original, and all are guaranteed to work. Downie provides instructions for each one and explains the underlying science, and also presents experimental variations that readers will want to try.

Publication bias in the social sciences
We studied publication bias in the social sciences by analyzing a known population of conducted studies—221 in total—in which there is a full accounting of what is published and unpublished. We leveraged Time-sharing Experiments in the Social Sciences (TESS), a National Science Foundation–sponsored program in which researchers propose survey-based experiments to be run on representative samples of American adults. Because TESS proposals undergo rigorous peer review, the studies in the sample all exceed a substantial quality threshold. Strong results are 40 percentage points more likely to be published than are null results and 60 percentage points more likely to be written up. We provide direct evidence of publication bias and identify the stage of research production at which publication bias occurs: Authors do not write up and submit null findings.
